Purpose: In the Agriculture industry, tortoises may not have a great commercial value compared with chicken and hoofed mammals; nevertheless, they have a substantial economic value for food, medicine, and ecological services. The empirical work was conducted at the Departmental Research Center (DRC), to investigate the impact of growth phases on body weight (BW) and morphometrics of different age groups. Design/ Methodology/ Approach: Eighty freshwater tortoises of 4 age groups (20 hatchlings, 20 juveniles, 20 sub-adults and 20 adults) were obtained from the Ministry of Forestry and Wildlife in Nigeria. A deep litter housing system was used for the present study. Tortoises were fed with cooked meat, concentrate, fermented cassava, and palm fruits. Findings: The mean BW ranged from 41.00g - 848.00g. The result revealed that the mean BW of the tortoise value (503g). The Coefficient of Variance (CV) of morphometrics ranged from 9.73% - 15.63%. The straight carapace length (SCL) had a higher CV value (15.63%), followed by plastron length (PL) (12.90%) and least value (9.73%) for carapace width (CW). There was a huge difference in all the morphometrics except SCL and CW for sub-adult and adult tortoises. The result revealed that SCL, CW, PL and plastron width (PW) differed distinctly from BW. The correlation coefficient of BW and morphometric of juvenile growth phase (JGP) and sub-adult phase (SAGP) ranged from (0.326 - 0.964) and (0.275 - 0.953) respectively. Research Limitation/Implications: This research focused on Nigeria's availability and sustainability of freshwater tortoises. Practical Implication: This paper has potential implications for understanding the management and improvement of the freshwater tortoise in Nigeria. Social Implication: This study will enhance the availability and development of freshwater tortoise for policy-makers in addressing sustainable food security through social, economic and environmental stability for the present and future generations. Originality/Value: This study is based on the data collected on body weight and morphometric traits during growth phases. [ABSTRACT FROM AUTHOR]

The aim of this study is to determine whether or not the breed and sex factors have an effect on the shape in the mandibles of Hamdani and Awassi sheep. A total of 31 mandibles were used. The samples were analyzed via geometric morphometric methods by using semilandmark. In the study, it was determined that the first principal component accounted for 36.52% of the total shape difference. According to principal component analysis, samples were clustered significantly in terms of breed; whereas, they were not clustered in terms of sex. In terms of the first principal component, the places where the shape differences were concentrated were the attachment sites of teeth to the mandible, between the second molar and ramus mandibulae, the processus coronoideus and the angulus mandibulae. The Mandibulae of Hamdani sheep had a higher body than the mandible of Awassi sheep. The mandibulae of male sheep was more voluminous than the mandible of female sheep, especially in the body area. Consequently, it is thought that the data obtained as a result of the study would serve as a reference for the ruminant mandible remains obtained from archaeological excavations.

The genus Swietenia includes two mahogany species, Swietenia macrophylla (King.), commonly known as Honduran mahogany, and Swietenia mahagoni (L.) Jacq, commonly known as Cuban mahogany. There are reports of morphologically intermediate forms between Cuban and Honduran mahogany that have been localized in some Caribbean islands. The main objective of this research is to distinguish morphologically intermediate forms between the parental species S. mahagoni and S. macrophylla based on leaf morphological characters. Phenotypic data from a total of 357 mahogany trees were collected in the province of Sancti Spiritus, Cuba. Rachis length, petiole length, leaflet length, leaflet width, number of leaflets and number of nerves were evaluated. Morphological descriptor analysis revealed significant differences in the morphometric variables of the evaluated leaves, with rachis length, number of leaflets, leaflet length, petiole length, leaflet width, and number of nerves being significantly higher in S. macrophylla than in S. mahagoni. ANOVA reflected the variance between all leaf morphological parameters evaluated between the two pure species with statistically significant difference. Using the function obtained in the first DC of the two species, the individuals in the mixed stands were classified into 71 morphologically intermediate forms, 45 S. macrophylla and 64 S. mahagoni. In the second DC with the two species and the morphologically intermediate forms, Wilks' partial lambda indicates that the variable "leaflet length" with 0.67 contributed most to the overall discrimination.

The drainage characteristics are basic information for watershed management. The morphometric analysis carried the slope contribution and linear, areal, and relief aspects. Takhar province is 390 km distance from Kabul. Located in the North Eastern Region of the country, the capital of Takhar province is Taluqan (Provincial Center). Badakhshan borders Takhar in the North-East, Panjsher in the south, Baghlan in the South-West and Kunduz in the North-West. Takhar is situated at an elevation of 801 meters above sea level and covers a land area of 12328.684 Km², representing 1.91 percent of the total Afghan territory. The SRTM (90 m) Digital Elevation Model (DEM), in conjunction with SOI toposheets, have been used to delineate the hydrological boundaries of the study area. The finding variation in the elongated shapes of the basins is due to the guiding effect of faulting and thrusting in the basin. The Rc of the basins is fewer than 1. It indicates that the infiltration rate varies throughout the basin. The Bangi, Farkhar, and Warsaj districts have low Fs, which indicates that there is less side flow for a shorter duration and high main flow for a longer duration. High Fs in Khwaja ghar, Taluqan, and Darqad districts with high side flow for a longer duration and low main flow for a shorter duration causing high peak flows in a shorter duration.

AbstractThe present study was designed with the aim to study morphometric characterization as well as phylogeny and diversity of the local Surguli goat at their breeding tract district Kohat through mitochondrial DNA region, i.e., Cytochrome C Oxidase Subunit One (CO1) gene. Morphometric data and blood samples were collected from thirty (30) pure goats. Morphometric analysis showed that sex had significant effect (p < 0.05) on body weight, body length, hearth girth and horn length while no significant effect (p > 0.05) was observed for other characteristics. The results also indicated that age had significant effect (p < 0.05) on height at rump, ear length, horn length and tail length while no significant effect (p > 0.05) was observed for other characteristics. The phylogenetic analysis through CO1 nucleotide sequences within nucleotide range 1–767 showed nine polymorphic sites segregating into eight haplotypes. The mean intraspecific diversity and mean interspecific diversity were calculated as 0.23 and 2.36%, respectively. Phylogenetic tree revealed that Capra Ibex and native Surguli goat have common ancestors. The morphometric and molecular results obtained from the present study can be exploited as a selection tool for breeding and overall improvement. [ABSTRACT FROM AUTHOR]

Aim: To provide normal values for the lumbar spinal canal, lumbar vertebral body and dural sac dimensions and canal body ratio by MRI for a Jordanian population sample. Material and methods: Three well trained observers reviewed 218 lumbar MRI scans performed between 2019–2021 (1090 lumbar levels) and obtained from the central computerized medical archive of three main governmental hospitals in north, central and south Jordan. All MRIs with alignment abnormalities (scoliosis and kyphosis), canal compression, vertebral disease (including fractures) or technical artifacts were excluded. The following were measured from L1 to L5 levels: the midsagittal diameters of the spinal canal and vertebral body, axial anteroposterior (AP), and transverse diameter of the vertebral body, dural canal and dural canal area. Data on sex and age were also documented. Results: The studied MRI scans included 113 males (51.8%) and 105 females (48.2%). Age ranged between 23–86 years old (mean 52.23 ± 13.125). The mid sagittal mid vertebral AP diameter of the lumbar spine range was 2.8–3.1 cm. The mid sagittal spinal canal diameter range was 1.3–1.5 cm. Canal body ratio was 3.3–3.6. The AP, transverse dural sac diameter ranges were 1.2–1.4 cm and 1.5–1.9 cm, respectively. Finally, the dural sac area ranged from 331–362 mm2. Conclusion: The dimensions of the lumbar spinal canal, vertebral bodies, and vertebral canal ratio at all levels were documented for a Jordanian population sample. Dimensions varied according to sex and when compared with other ethnic groups (Asian and African). The findings suggest that canal stenosis criteria should take these differences into consideration.

Trichopodus, the genus of dwarf gourami fish, is the oldest genus in the Osphronemidae family, with six valid species, three of which are found in Sumatra. In this study, the status, distribution, and morphometrics of Trichopodus leerii, T. pectoralis, and T. trichopterus from Sumatra were observed and analyzed. Although these species can be distinguished based on phenotypic characteristics, it is still possible to misidentify them in small or preserved samples. In this study, analyses were carried out on specimens in the collection of the Museum Zoologicum Bogoriense, combined with literature on the species status. The results showed that T. trichopterus and T. pectoralis were in the least concern category. T. trichopterus had the widest distribution, followed by T. pectoralis. T. leerii had the smallest distribution and is in a near-threatened conservation status. Further analysis revealed that 23 of the 25 measured morphological characteristics were informative, with the first three axes of a principal component analysis on morphometric data explaining 51.28% of the total variance in the sample. The three species were distinguished using a combination of pectoral fin length, eye diameter, pelvic fin length, and anterior snout width. Cluster analysis showed that there is consistency in the morphometrics of the species from various sample locations, where the same species are in the same clade. This research contributes to our understanding of the status and distribution of the species in genus Trichopodus and employs morphometric analysis to provide a practical key to classifying them in Sumatra.

Yellowtail Fusilier (Caesio cuning) is one of the fish caught by fishermen landed in Kaliadem, which is then sold at Muara Angke Fish Market, Jakarta. (Caesio cuning) has high economic value and has been widely consumed by various circles of society. This study aims to determine the heavy relationship with morphometric variation of (Caesio cuning) to obtained fish growth pattern. The collection of 30 fish samples was carried out in April 2018 with a survey method at the Muara Angke Fish Market. Morphological observations were carried out traditionally using a ruler with 0.01 mm accuracy and weighed using analytical scales with an accuracy of 0.01 gr. The analysis used for morphometric and fish weight measurement data is multiple linear regression. The results obtained that the overall morphometric character affects fish weight by 98.4%, where the morphometric characters in the mouth length (PM) have a positive effect on fish body weight with a p-value of 0.048 and coefficients of 21.843. This figure can be assumed that every time there is an addition to the mouth length of 1cm, it will increase by 21.8gr fish body weight with category positive allometric growth pattern.

This study evaluated the morphological diversity of some Nigerian accessions of Bambara groundnut. Field experiments were conducted in Nigeria in two locations and the phenotypic variation of Bambara groundnut accessions evaluated in 3 years (2017–2020) using a randomized complete block design. Twenty-eight quantitative and 10 qualitative traits were observed. Twenty-three out of the 28 quantitative morphological traits showed significant differences. TVSu-589 (28.85) and TVSu-670 (28.57) had the highest plant height; TVSu-572 (121.52), TVSu-271 (113.10) and TVSu-336 (104.15) had the highest 100-seed weight. Genetic variations were also observed in seed colour, terminal leaflet shape, petiole colour and eye pattern. Principal component analysis showed PC1 constituting 23.36% and PC2 constituting 15.76% of the total variation, while the first eight principal components with eigenvalues ≥1 revealed 77.28% of the total variation. Cluster analysis grouped the accessions into four groups. Based on yield data in this study, accessions TVSu-594, TVSu-350, TVSu-336, TVSu-1242, TVSu-129, TVSu-14, TVSu-179, TVSu-2100, TVSu-261 and TVSu-589 were the best for yield and are recommended for further evaluation to improve yield. This study showed that a wide range of diversity exists in Bambara groundnut of Nigerian origin that could be useful for further utilization of genetic resources and improvement.

In this study, the otolith morphology of yellowtail snapper (Ocyurus chrysurus) was used for stock identification based on different shape analyses viz. morphometric parameters with shape indices, Elliptical Fourier descriptors (EFD), wavelet transform (WT), and landmarks. The samples were collected from Fortaleza (Ceará) and Recife (Pernambuco) in the coastal waters of Brazil to identify stocks and determine the best method for stock discrimination of O. chrysurus. The result showed no significant difference between these two regions which was supported by the Linear Discriminant Analysis (LDA). To select the best discrimination methods a correct classification through jack-knifed and Wilks’ λ test was performed. The morphometric parameters with shape indices showed a correct classification of 25% and the landmark method’s correct classification was 33.1%. These two methods had a lower correct classification than the otolith contouring methods (EFD = 42.3% and WT = 43.5%). Also, the Wilks’ λ test showed lower power discrimination for morphometric with shape indices and landmark method (λ= 0.904 and λ= 0.808, respectively), in comparison with the two contouring methods (EFD λ = 0.688 and WT λ = 0.601). These results indicate that the most suitable methods for observing small variations in O. chrysurus otoliths can be EFD and WT. [ABSTRACT FROM AUTHOR]

Chiari malformation (CM) is characterized by herniation of the cerebellar tonsil(s) and/or medulla oblongata into the spinal canal, resulting in various morphometric abnormalities. The current study aimed to evaluate the magnetic resonance imaging (MRI) findings and morphometric features of the craniocervical region in patients who underwent surgery for CM. Demographic and radiological data were collected from 59 patients who underwent surgery for CM and a control group of 58 randomly selected nonsurgical patients. For between-group comparisons, Continuous variables were described as the mean (±SD) or median (IQR) and categorical variables as frequency (%). The mean age of the control group participants was 33.38 years. The mean age of patients in the CM group at the time of surgery was 33.83 years. The diameter of the foramen magnum, the maximum anteroposterior diameter of the C1 vertebra, the maximum diameter of the spinal canal at the C2 vertebra, and the atlantodental interval were all positively correlated with the total cerebellar tonsil length [r=0.54, 0.37, 0.42, 0.71]. Comparisons of total cerebellar tonsil length with other morphological and clinical variables, including contact between the brainstem and clivus, basilar invagination, preoperative hydrocephalus, remnant cartilage between the odontoid and C2 corpus, and associated craniovertebral junction anomalies, revealed no other significant correlations. CM is associated with many structural anomalies in the brain. However, there is relatively little detail in the existing literature on the morphometric parameters associated with the malformation. The findings of this study provide insights for future research and contribute to knowledge of the morphometric features of CMs in general and CMs in patients requiring surgical management in particular.

Buffaloes (Bubalus bubalis) in Kaliakah Village are exploited in the makepung lampit tradition, in addition to food and agricultural tools. However, the population of buffaloes in Kaliakah Village is very small hence information on their morphology is needed to inform conservation efforts. This study aimed to describe qualitative and quantitative characters in the morphology of male and female buffaloes in Kaliakah Village. This survey study was analyzed on 24 male buffaloes and 30 female buffaloes. Qualitative characters observed consist of body shape, body color, eye color, and horn shape, while quantitative characters measured consist of chest girth (CG), leg length (LL), body length (BL), head length (HL), neck length (NL), tail length (TL), and estimated body weight (BW). The study results revealed variations in body shape (stocky and fat), body color (black and albino), and eye color (black and reddish black) in both male and female buffaloes. Male buffaloes have a CG of 167 ± 19.18 cm, LL of 57.63 ± 5.23 cm, BL of 128.13 ± 7.60 cm, HL of 31.38 ± 3.50 cm, NL of 49.25 ± 5.99 cm, TL of 61.88 ± 6.53 cm, and BW of 740.79 ± 198.59 kg. Female buffaloes had a CG of 160.40 ± 16.53 cm, LL of 57.17 ± 4.31 cm, BL of 127.39 ± 7.55 cm, HL of 30.72 ± 3.67 cm, NL of 72 ± 5.46 cm, TL of 60.56 ± 6.48 cm, and BW of 700.94 ± 168.87 kg. Based on ANOVA (one-way) analysis, there was no significant differences between the quantitative characters of male and female buffaloes. Based on an analysis of correlation, there are differences in quantitative characters that are strongly correlated among male and female buffaloes. [ABSTRACT FROM AUTHOR]

A study was conducted to establish the correlation between morphometric traits and carcass yield as well as predict carcass yield from morphometric traits in three strains of broiler chicken. The morphometric traits studied were Wing length (WL), Keel length (KL), Thigh length (TL), Body girth (BG) and Body height (BH), while the carcass yield were dressed weight (DRSWT), thigh weight (TWT) and breast weight (BRSWT). A total of 144 birds were divided into three treatment groups according to strains and each group was randomly replicated four times with 12 birds per replicate. The data obtained were subjected to correlation analysis, linear and multiple regression analyses were also used to predict body weight and carcass yield from morphometric traits. The results showed that the correlation between body weight, morphometric traits and carcass traits were significantly positive (p<0.001) with correlation coefficient ranging from 0.068 - 0.993, 0.216 - 0.882 and 0.027 - 0.990 in Arbor Acres, Ross 308 and Cobb 500 respectively. The correlation between breast weight and all morphometric traits were positive and significantly high (p<0.001) in all the three strains of broiler studied. suggesting dependency among these traits. Simple linear regression equation predicted carcass yield from morphometric traits in all the three strains, as R2 value computed using each morphometric trait in the three strains were above 50%. However, inclusion of more than one trait in the regression model increased the accuracy of prediction. It could be recommended that more than one trait should be included in the regression model for greater accuracy. [ABSTRACT FROM AUTHOR]

The purpose of this study is to map and geographically locate areas with a high probability of natural events occurring such as "rockfall". In this context, a multi-method approach is proposed to characterize and evaluate the potential vulnerability of an unstable ground as well as rockfall risk, through morpho-tectonic, geological, and morphometric analysis integrated into a geographic information system (GIS). Several parameters such as slope, lithology, lineaments, morphology, land use, and rainfall have been integrated and indexed in a geographic information system to be able to develop the rockfall risk map that allowed us to detect and geographically delimit the unstable areas in the Korbous cliff. The studied area presents a contrasted territory, from both morphological and geological points of view. The steep slopes' rockfalls are quite frequent and constitute a potential risk to infrastructure and habitats at the bottom of slopes such as Korbous village, Ain Oktor, and MC 128 road. The proposed rockfall risk map, in this study, would serve as a guide and decision-support tool for the choice of preventive measures for reducing disaster risk (RDR). [ABSTRACT FROM AUTHOR]

In this comprehensive study, we examined 15 distinct morphometric characteristics within seven Indonesian hornbill species. Precise measurements of these morphometric traits were obtained using 0.1 mm calipers and a 1000 mm measuring tape. Our analysis encompassed a total of 85 individuals representing seven hornbill species: Anthracoceros albirostris (18 individuals), A. malayanus (4 individuals), Aceros cassidix (3 individuals), Rhyticeros plicatus (7 individuals), R. undulatus (36 individuals), Buceros bicornis (1 individual), and B. rhinoceros (16 individuals). To elucidate the morphometric ratio data, we employed a robust analytical approach involving the Principal Component Analysis (PCA), Discriminant Analysis, and Cluster Analysis. Our findings underscored a clear separation between hornbill genera, primarily attributed to a combination of PC1 (pertaining to body length) and PC3 (associated with beak morphology). Key morphometric traits that delineated these genera on PC1 included tail length, beak length, horn length, total length, and wing length. Meanwhile, on PC3 (characterizing beak morphology), the distinguishing features encompassed beak width, horn width, and tarsus length. Additionally, our analysis unveiled the characteristics that distinguish species within the genera Anthracoceros and Rhyticeros to be a composite of tail length and head length. This discerning morphometric data facilitated the clustering of seven hornbill species into two distinct groups: Group I comprised A. albirostris and A. malayanus, while Group II included R. plicatus, R. undulatus, A. cassidix, B. rhinoceros, and B. bicornis. Notably, these groups exhibited a 31.93% degree of similarity. This dataset holds immense potential for facilitating genetic classification and comparative studies of Indonesian hornbills.

The study examined the spatial analysis of the morphometric characteristics of the Lower Orashi River, Niger Delta Region, Nigeria. The river course was segmented into 30 equal distances of 4.8m from each other and at each point, the morphometric parameters like width, depth, and flow velocity. The discharge was measured from these parameters. Descriptive and inferential statistics were employed for data analysis while results are presented using tables and graphs. Results showed that width of the river ranged from 77.90m to 2788.00m with the mean width of 318.83m. The depth ranged from 2.10 to 7.60m with the mean depth recording 4.14m as it was higher at the upper section of the river while it becomes lower as it is entering the Atlantic Ocean. Furthermore, width was significantly correlated with the depth (r= -0.556, p

In this study, the Tigris bream Acanthobrama marmid individuals (44 females and 31 males) were captured from the Tigris River. The scale size (as centroid size) and shape were analyzed separately using 2–dimensional geometric morphometric methods. Procrustes ANOVA revealed significant differences in scales size between sexes, while no difference in shape was observed. Groups based on season and age showed significant differences in both size and shape. Female individuals had larger scale sizes than males, with the scales of the Autumn group being larger than those of the Spring and Summer groups. Scale size also increased with age groups. PCA analysis showed variation in the first five components when examined by age, season, and gender. CVA and DFA results indicated significant differences in shape between different age groups and seasonal groups, but no significant differences between sexes were observed.

Abstract The aim of the research was to study the quality of livestock production in relation to carcass quality and body weight. The research was conducted descriptively using exploratory techniques on cattle and their products (carcasses). Research for 1 (one) month at the cattle slaughtering location in Manokwari district, namely the first slaughtering location is Transito Wosi, the second slaughtering location is Rendani and the third location is Wosi Market. Samples were obtained randomly by selecting 86 male cattle which were slaughtered with the following criteria: Age 1-2 years, Age 2-3 years, Age 3-4 years, Age 4-5 years and Age > 5 years. The results of this study indicate that the percentage of cattle slaughtered is based on age, namely 2-3 years of 67.44%, 3-4 years of 43.99%, while the highest carcass weight is in the 3-4 year age category of 162.89 ± 77. 32 kg, and the longest carcass length in the 4-5 year old cattle category was 122.40 ± 11.80 cm. Slaughter weight has a close relationship (94.72%) with carcass weight, carcass percentage and carcass length. Differences in age category had no effect on carcass weight, carcass length and carcass percentage. Body weight is strongly influenced by body length and chest circumference. It is necessary to carry out further research with observations starting from livestock rearing, feed given, livestock handling before to after slaughter, carcass quality (thickness of fat, area of rib eye veins).

The South American tomato leaf miner, Tuta absoluta (Meyrick) (Lepidoptera: Gelechiidae), invaded Algeria in 2008 and caused severely significant devastation to tomato plants. This study designed to evaluate the thermal requirements and assess the influence of temperature on the life cycle of this devastating pest under controlled greenhouse environment. Through a series of experiments, we observed four generations of T. absoluta at various temperatures and relative humidity levels. We chased the population dynamics by using pheromone traps and revealed four overlapping generations, each of which corresponded to peaks in adult flying activity. These peaks were influenced by the greenhouse's temperature and humidity levels. The development of successive and overlapping generations of T. absoluta requires temperatures ranging from 25 to 30 °C, coupled with humidity levels between 58.5 % and 69.33 %. Additionally, the morphometric analysis of T. absoluta larvae allowed the identification of four larval stages characterized by lengths of 2.5 mm for the first instar, 2.5 to 4 mm for the second instar, 4.5 to 5.5 mm for the third instar, and 6 to 7 mm for the fourth instar. By studying the biology of T. absoluta and its thermal and hygrometric requirements, we can develop an integrated pest management strategy that efficiently battles against this destructive pest.

Abstract Background Morphometric study of the bony elements of the appendicular skeleton in the ostrich was fully described and identified. The appendicular skeleton included the bones of the pectoral girdle, the wing, the pelvic girdle and the pelvic limb. Results The shoulder girdle of the ostrich included the scapula and coracoid bones. The scapula appeared as a flattened spoon-like structure. The coracoid bone appeared quadrilateral in outline. The mean length of the scapula and coracoid (sternal wing) were 15.00 ± 0.23 and 10.00 ± 0.17 cm, respectively. The wing included the humerus, ulna, radius, radial carpal bone, ulnar carpal bone, carpometacarpus and phalanges of three digits. The mean length of the humerus, radius, and ulna were 33.00 ± 0.46, 10.50 ± 0.40 and 11.50 ± 0.29 cm respectively. The carpometacarpus was formed by the fusion of the distal row of carpal bones and three metacarpal bones. Digits of the wing were three in number; the alular, major and minor digits. Os coxae comprised the ilium, ischium and pubis. Their mean lengths were 36.00 ± 0.82 cm, 32.00 ± 0.20 and 55.00 ± 0.2.9 cm, respectively. The femur was a stout short bone, that appeared shorter than the tibiotarsus. The mean length of the femur, tibiotarsus, and tarsometatarsus were 30.00 ± 0.23, 52.00 ± 0.50 and 46.00 ± 0.28 cm. Tibiotarsus was the longest bone in the pelvic limb. The fibula was a long bone (44.00 ± 0.41 cm) lying along the lateral surface of the tibiotarsus. The tarsometatarsus was a strong long bone formed by the fusion of the metatarsal (II, III, IV) and the distal row of tarsal bones. It was worth mentioning that metatarsal II was externally absent in adults. Conclusions In the appendicular skeleton of ostrich, there were special characteristic features that were detected in our study; the clavicle was absent, the coracoid bone was composed of a sternal wing and scapular wing, the ulna was slightly longer in length than the radius. The coupled patellae i.e., the proximal and distal patella were observed; and the ostrich pedal digits were only two; viz., the third (III) and fourth (IV) digits.

Identifying the most critical sub-watershed or reservoir catchment in relation to water spread, pattern of soil erosion and aquifer recharge in a basin can be highly useful for implementing conservation measures. Thus, a study was undertaken to (i) review the various parameters used in watershed morphometric analysis with their appropriate mathematical expressions, (ii) discuss their importance in watershed prioritization and conservation planning, (iii) formulate mathematical relationship between important morphometric parameters, and (iv) discuss the different tools and techniques used for sub-watershed prioritization. All the morphometric parameters are important for hydrologic characterization and watershed prioritization. However, some of them are highly significant for better understanding of the watershed drainage network, geometry, drainage texture and relief parameters. The smaller values of shape parameters viz. form factor (Ff < 0.78), elongation ratio (Re < 0.80) and circularity ratio (Rc < 0.50) indicate a basin having elongated shape and flatter peak for extended period and permit a greater soil erosion/loss as these are inversely related with erodibility. Whereas, the greater values of Ff (>0.78), Re (>0.80) and Rc (>0.50) indicate a basin having circular shape and higher peak for smaller period. The higher values of drainage density (Dd > 0.60), drainage texture (Dt > 0.6) and stream frequency (Fs > 10) also indicate higher erosion due to their direct relationship with erodibility. As per this review, watersheds can be prioritized by several techniques including morphometric analysis, LULC change analysis and soil loss estimation. However, the morphometric analysis-based watershed prioritization is found to be laborious and time consuming as it involves numerous parameters, and hence can be replaced by modern data reduction methods like principal component analysis (PCA) using suitable software's like R, SPSS and XLSTAT. Thus, geospatial techniques-based catchment/watershed prioritization supported with an appropriate data dimension reduction technique (e.g. PCA) would be highly significant for planning conservation measures and management in a watershed.' HIGHLIGHTS Remote sensing and GIS-based watershed prioritization are useful for land and water management.; Smaller values of shape parameters indicate higher soil erosion.; Higher values of linear parameters also indicate higher erosion.; Principal component analysis (PCA) using any suitable software such as R, SPSS, and XLSTAT makes the watershed prioritization time-efficient.;

Kaliurang is one of the local taro cultivars in Indonesia, potentially due to its high productivity and delicacy. This study analysed morpho-genetic variation between one diploid and three tetraploid Kaliurang taro clones from in vitro polyploid induction after plantlet acclimatization in the greenhouse for 6 weeks. Plants' morphological characters were analysed using the unweighted pair group method with arithmetic mean (UPGMA) method based on 50 characters according to the taro descriptor from the International Plant Genetic Resources Institute (IPGRI). Furthermore, a morphometric characterization based on the Euclidean distance of 17 digitations from mature leaves, was analysed with the Analysis Phylogenic and Evolution package in R software. DNA band pattern was also performed with ISSR to analyse the clone's genetic variance. The results showed morpho-genetic character diversity in diploid and tetraploid plants. A plant morphological study revealed that 22 out of 50 characters were distinct, with similarity coefficients ranging from 0.35 to 0.78. Leaf geometric morphometric analysis showed changes in five digitations and formed three clusters. Twelve ISSR primers out of twenty amplified the sequence of the Kaliurang taro genome to yield two clusters with a similarity coefficient of 0.71-0.83. Based on these three characterization approaches, tetraploid clones (K2 and K3) consistently differed morphologically from diploid clones (K0).

The study investigates morphometric features, seminal profile and post-thaw semen quality of Munshiganj cattle. Morphometric features were measured using measuring tape from 20 Munshiganj cattle while coat color was measured by observing in naked eye. Fresh and post thaw semen quality parameters were analyzed using Computer Assisted semen analyzer (CASA). Coat color of Munshiganj male cattle were creamy white to dull pinkish and female were white to creamy. The mean body weight, body length, hearth girth, height at wither, head length, head width, ear length, ear width, fore leg length, hind leg length, tail length, tail doc circumference, horn length, horn diameter and mouth circumference were 362.80 kg, 137.31 cm, 160.66 cm, 135.21 cm, 50.97 cm, 20.58 cm, 19.75 cm, 9.88 cm, 73.02 cm, 74.84 cm, 106.10 cm, 20.75 cm, 13.60 cm, 16.12 cm and 43.00 cm, respectively. There was significant difference (p 0.05) on post thaw semen quality except slow motility and proximal droplet percentages. Munshiganj cattle had a distinctive phenotypic feature with standard quality semen and had no effect of egg yolk free and egg yolk based diluters on post thaw semen quality.

Seagrasses are long-lived, clonal plants that can integrate fluctuations in environmental conditions over a range of temporal scales, from days to years, and can act as barometers of coastal change. There are many estimated seagrass traits and ecosystem parameters that have the potential to reflect ecosystem status, linking seagrass condition to natural and anthropogenic drivers of change. We identified five seagrass indicators and seven metrics that are suitable, affordable and frequently measured by 38 monitoring programs across the Gulf of Mexico (GoM). A specific set of ratings and assessment points were formulated for each measurable metric. We determined metric ratings (Acceptable, Concerning, Alarming) and validated assessment points using long-term monitoring data from Texas and Florida, coupled with existing literature and input from a panel of seagrass biologists. We reported scores using a blue-gray-orange (Acceptable-Concerning-Alarming) scale to summarize information in a format accessible to the public, resource managers, stakeholders, and policymakers. Seagrass percent cover, shoot allometry and species composition were sensitive indicators of large-scale climatic disturbances (droughts, hurricanes). Severe drought led to reductions in total seagrass cover and leaf length in Upper Laguna Madre, Texas, and Florida Bay; however, Syringodium filiforme was disproportionally affected in Texas while Thalassia testudinum beds responded strongly to drought impacts in Florida. Hurricanes Harvey (TX) and Irma (FL) also resulted in loss of seagrass cover and diminished leaf length in the Texas Coastal Bend and Florida Keys; both storms largely impacted T. testudinum and to a lesser extent, S. filiforme. Many of the metrics within these affected bays and basins received either a “Concerning” or “Alarming” rating, driven by the impacts of these disturbances. Our proposed indicators serve as a tool to evaluate seagrass condition at the bay or basin scale. Moreover, the indicators, metrics, and assessment points are amenable to large-scale evaluations of ecosystem condition because they are economically feasible. This framework may provide the foundation for a comprehensive assessment of seagrass status and trends across the entire GoM.

Background: The anatomical parameters of hip joint will be of immense importance to orthopedicians, radiologists and prosthetists. These parameters help in designing patient specific implants and can be utilized to understand etiopathogenesis of osteoarthritis. Aim and objective: The objective of this study is to compare acetabular diameter (AD) and acetabular depth (Depth) morphology in humans in terms of age and gender. Material and Method: This is a prospective, descriptive, cross sectional and observational study conducted at Department of Anatomy and Radiology, Index Medical College, Indore from January 2020 December 2022. Study group divided into 3 groups: Group A: 18-35 years, Group B: 36-55 years and Group C: 56-75 years. Result: It is defined as the angle between the line connecting the lateral edge of the acetabular roof touching the lower iliac tip of acetabular surface and a line parallel to the pelvic tear drop. The angle between the centre line of both femoral heads and the line from centre towards the anterior margin of acetabulum. The angle between the centre line of both femoral heads and the line from centre towards the posterior margin of acetabulum.CONCLUSION: The depth studied on acetabulum in the present study showed statistically significant differences between males and females. Studies based on depth of acetabulum are relatively few in the literature, hence the findings of the present study can provide a guideline for further studies on acetabulum. Considering that total hip replacement is a common surgery performed now a day, awareness of the dimensions of the acetabulum is of immense importance to the orthopaedic surgeons.

The climbing mouse is a rare, small mammal listed as an endangered species on the China species red list. Molecular phylogenetic analyses and the evolutionary history of the genus remain unexplored because of the extreme difficulty in capturing individuals and their narrow distribution. Here, we collected 44 specimens, sequenced one mitochondrial and eight nuclear genes, and integrated morphological approaches to estimate phylogenetic relationships, delimit species boundaries, and explore evolutionary history. Molecular analyses and morphological results supported the validity of these four species. Here, we describe two new species, Vernaya meiguites sp. nov. and Vernaya nushanensis sp. nov., and recognize Vernaya foramena, previously considered a subspecies of Vernaya fulva, as a valid species. The estimated divergence time suggests that the climbing mouse began to diversify during the Pliocene (3.36 Ma). [ABSTRACT FROM AUTHOR]

We conducted a morphometric study and wall texture analysis on extant and fossil specimens of the planktonic foraminifera Globigerina falconensis plexus. Our global data reveal morphological inconsistencies between fossil and extant populations. Our results are significant as G. falconensis is widely used in palaeoceanographic studies in conjunction with its sister taxon G. bulloides. Morphologically these two species are similar, with the main difference being the distinctive apertural lip present in G. falconensis. We selected cores covering the entire stratigraphic range of G. falconensis, from the early Miocene to current day, spanning sites from high latitudes in the North Atlantic Ocean and the southern Indian Ocean to sites in equatorial regions. The morphology found in the modern ocean is not consistent with the Miocene holotype of Globigerina falconensis Blow described from lower Miocene sediments in Venezuela. A more lobate morphology evolved in the late Miocene, thus, a new name is required for this morphotype, coexisting in the modern oceans with G. falconensis s.s. We thus describe the new morphospecies, G. neofalconensis for the more lobate forms which evolved in the late Miocene and inhabit the modern oceans. Additionally, we report a pseudocancellate wall texture present in the G. falconensis plexus. We use the molecular sequences from the PR2 database to explore the generic attribution of the G. falconensis lineage, confirming its close relationship with G. bulloides and its retention in the genus Globigerina.

In nature, organisms are exposed to variable environmental conditions that impact their performance and fitness. Despite the ubiquity of environmental variability, substantial knowledge gaps in our understanding of organismal responses to nonconstant thermal regimes remain. In the present study, using zebrafish (Danio rerio) as a model organism, we applied geometric morphometric methods to examine how challenging but ecologically realistic diel thermal fluctuations experienced during different life stages influence adult body shape, size, and condition. Zebrafish were exposed to either thermal fluctuations (22–32°C) or a static optimal temperature (27°C) sharing the same thermal mean during an early period spanning embryonic and larval ontogeny (days 0–30), a later period spanning juvenile and adult ontogeny (days 31–210), or a combination of both. We found that body shape, size, and condition were affected by thermal variability, but these plasticity‐mediated changes were dependent on the timing of ontogenetic exposure. Notably, after experiencing fluctuating temperatures during early ontogeny, females displayed a deeper abdomen while males displayed an elongated caudal peduncle region. Moreover, males displayed beneficial acclimation of body condition under lifelong fluctuating temperature exposure, whereas females did not. The present study, using ecologically realistic thermal regimes, provides insight into the timing of environmental experiences that generate phenotypic variation in zebrafish. [ABSTRACT FROM AUTHOR]

Galls function as provide shelter for gall inducers, guarding them against their natural enemies. Previous research has illuminated the interactions between galls, gall inducers, and their corresponding parasitoids within various caltrop plants. However, less is known about these relationships within Nitraria sibirica , particularly regarding the efficacy of parasitism. Therefore, this study aimed to identify the morphometric relationships among the swollen galls, gall inducers, and their parasitoids. Two species of gall inducers and three species of parasitoids were obtained from the swollen galls of N. sibirica. The correlations of the parasitization indexes, the lifespan of gall inhabitants, and temperature and the morphometric relationships between the galls and their inhabitants were analyzed. The dominant gall inducer identified was Contarinia sp. (Diptera: Cecidomyiidae). Furthermore, it was observed that three solitary parasitoids attacked Contarinia sp. in the swollen galls, with only Eupelmus gelechiphagus acting as an idiobiont ectoparasitoid. The dominant parasitoids were Platygaster sp. and Cheiloneurus elegans at sites 1 and 2, respectively, with Platygaster sp. displaying greater abundance than C. elegans in the swollen galls. The lifespan of the gall inhabitants shortened gradually as the temperature increased. Moreover, the optimal number of gall chambers ranged from two to four per swollen gall with maximized fitness, which can be considered the optimal population density for the gall inducer Contarinia sp. Morphometric analysis exhibited a strong linear correlation between gall size and chamber number or the number of gall inhabitants, as well as a weak correlation between gall size and body size of the primary inhabitants of swollen galls. Our results highlight the importance of the biological investigation of parasitoids and gall inducers living in closed galls with multiple chambers and may pave the way for potential application in biological control.

Summary: Deladenus taedae n. sp. was isolated from loblolly pine wood (Pinus taeda) intercepted in Ningbo, P.R. China, in imports from the USA. This new species is morphologically described and illustrated and characterised molecularly. Both mycetophagous and infective forms were recovered and described. The new species, D. taedae n. sp., resembles some other species of Deladenus in which the excretory pore is situated anterior to the hemizonid. The new species is characterised by the lateral fields with six lines, pointed tail ending and small spermatheca in mycetophagous females and short stylet in infective females. In mycetophagous females, the excretory pore is 74-98 μ m from the anterior end and 37-54 μ m anterior to the hemizonid. The partial rDNA 18S, complete internal transcribed spacer, 5.8S and partial 28S D2/D3 genes were amplified and sequenced. Phylogenetic analyses of the genes distinguished this new species from all other sequenced Deladenus species. [ABSTRACT FROM AUTHOR]

The population status and age distribution of Baobab (Adansonia digitata L.) trees in Zing Local Government Area of Taraba State, Nigeria, were studied. Six (6) wards cutting across 25 villages were purposely selected, and baobab clusters were randomly sampled. Data on the number of stands, stand density (SD) per cluster, height, CBH, crown cover (CC), number of branches (NB), and number of flowers or fruits (NF) were recorded. A total of 851 baobab stands were recorded in an area covering 751,105.56 m2 . Zing AI, AII, and B recorded 18 clusters (35.25%) and a total stand of 370 (43.46%), while Dingding, Monkin, and Yakoko recorded 33 clusters (54.71%) and a total stand of 481 (56.92%). Baobab clusters were more aggregated in Dingding, Monkin, and Yakoko than in Zing AI, AII, and B. Mean CBH (4.23+0.26), mean CC (3.78+0.48), mean NB (5.70+1.65), mean NF (18.94+13.94), and area of clusters (416,135.91m2 ) were highest in Zing AI, AII, and B, while total stand (481), SD (1.43E-3), and mean baobab height (13.94+1.63) were highest in Dingding, Monkin, and Yakoko, although not statistically significant (p>0.05). The results also revealed very low natural regeneration, as only 66 (7.76%) juveniles and 785 (92.24%) adults were recorded, with no single seedling sighted. We therefore, recommend that extensive research be conducted into unearthing the factors limiting natural regeneration and poor recruitment of young baobab trees. [ABSTRACT FROM AUTHOR]

Wetlands' morphometric or shape properties, such as their area and perimeter, impact a multitude of ecosystem functions and services. However, current models used to quantify these functions often only use area as an independent variable, as the static area and perimeter of different wetlands have been found to be closely related. The study uses monthly inundation maps, derived from remote sensing data, to assess the temporal covariation of geographically isolated wetlands' perimeter and surface area. The results show that using static representations of wetlands to evaluate temporal dynamic perimeter–area relationships can introduce significant discrepancies and that these discrepancies can be reduced if evaluations using static data are performed separately for each wetlandscape. This study concludes that models that use implicit area–perimeter relationships based on static wetland representations, as is usually the case, should be applied with caution. Additionally, it suggests that incorporating perimeter–area relationships from temporally dynamic data can improve estimates of wetland functions. [ABSTRACT FROM AUTHOR]

Samples of small flying fox were collected from Bababu Dinagat Islands and Hundred Islands Pangasinan and were subjected to gross morphology and histological evaluation. Gross anatomy evaluation revealed that the heart of small flying fox is oval in shape with the base of the heart being wider than the apex and surrounded by pericardium that appears as a transparent and firm structure. Fats and lymphatic tissue are also found around the heart and its blood vessels. The heart has a mean weight of 4.7 ± 0.42 grams for male and 4.7 ± 1.92 grams for female. Its left and right atrial wall showed no difference in their thickness and has a smooth wall while the left ventricular wall is twice the thickness of the right ventricular wall. The heart samples have two papillary muscles on the right and left ventricle. The number of chordae tendinae on the left ventricle is 5 while it has four chordae tendinae on the right ventricle. Female small flying fox right lung have a mean length of 5.4 ± 1.47 cm, mean width of 6.47 ± 0.47 cm and mean weight of 6.83 ± 1.90 grams. The male small flying fox right lung has a mean length of 5.50 ± 0.14 cm, mean width of 6.45 ± 0.35 cm and mean weight of 6.85 ± 0.07 grams. The female small flying fox left lung has a mean length of 5.17 ± 0.90 cm, mean width of 5.17 ± 0.61 cm and mean weight of 5.0 ± 0.96 grams. The male small flying fox left lung has a mean length of 5.15 ± 0.35 cm, mean width of 5.15 ± 0.64 cm and mean weight of 5.0 ± 0.28 grams.

The bronchioles are lined with simple cuboidal epithelium while the alveoli are lined with simple squamous epithelium. Type I and Type II pneumocytes were also observed. [ABSTRACT FROM AUTHOR]

The Crassostrea gasar (C. gasar) are economically important bivalves. The study investigated the physico-chemistry, the morphometrics and microbial profiles of C. gasar, water, and sediment from the Lagos Lagoon. The physico-chemistry and morphometry of C. gasar were determined using standard methods while the microbial were identified by Vitek 2 automated system. The mean Total Heterotrophic Bacterial Counts (Log CFU/mL) of C. gasar flesh and shells ranged from 5.28 ± 0.3 to 5.41 ± 0.3 and 5.49 ± 0.1 to 5.62 ± 0.3 respectively. The mean total coliform counts of sediment ranged from 4.34 ± 0.2 to 4.39 ± 0.2 Log CFU/mL, while the highest mean faecal coliform counts and total fungal counts of water samples were 2.41 ± 0.3 and 2.41 ± 0.1 Log CFU/mL, respectively. Vibrio spp, Pseudomonas aeruginosa, Staphylococcus aureus, Bacillus spp, Streptococcus faecalis, Escherichia coli and Aspergillus niger were the species found in all samples in varying percentages. The median-sized C. gasar had the highest values of 7.5 – 12.4 cm (TL); 4.5 – 7.4 cm (MW); and 80.5 – 160.4 g (TW). The highest mean values for surface water temperature, pH, salinity, Chemical Oxygen Demand and Phosphate were 27.3 ±1.51oC, 29.8 ± 1.94, 16.5 ± 0.39 ‰. 7.26 ±0.01 mg/L and 0.39 ± 0.01 mg/L respectively. This study revealed that C. gasar from the riparian swampy areas harboured some potential pathogenic organisms of significant public health concern and can contribute to the spread of illnesses when consumed.

Resistant rice varieties are considered to be a potential alternative for controlling the plant-parasitic nematode Meloidogyne graminicola in the field due to their joint economic and environmental sustainability features. However, the emergence of virulent pathogen forms threatens natural resistance durability. In this study, we isolated a virulent M. graminicola population from a naturally infested field in Cambodia that overcomes the resistance of the Oryza sativa Zhonghua 11 rice variety. We used molecular (internal transcribed spacer of rDNA and mitochondrial markers) and morphological approaches to unequivocally identify and confirm the species identification. Few intraspecific variabilities in traits between the virulent pathotype and several avirulent pathotypes were found. Remarkably, histological analysis showed the absence of a hypersensitive response (HR) on root cells surrounding the nematode in the "virulent pathotype–Zhonghua 11" interaction. In addition, the virulent pathotype reproduced to a significant extent in two other Oryza sativa varieties known to be resistant to M. graminicola. However, this virulent population was unable to overcome the previously described resistance in three Oryza glaberrima varieties. We concluded that the virulent M. graminicola pathotype isolated in this study could compromise rice breeding programs based on the sole use of known resistant O. sativa gene pools. The identification of this virulent pathotype should provide the genetic resources needed to study the molecular mechanisms that may enable M. graminicola to bypass HR resistance.

Introduction and Objective Gully erosion affected by many factors causes the destruction and loss of large volumes of soil along with great economic and social damage. The variability of diversity, the number and size of the influence of different factors from one point to another and the difference of their participation in the formation and expansion of gullies is based on the conditions of the land. Such conditions have caused more researches to be carried out to identify as many factors as possible in the phenomenon of gully erosion and the extent of their participation in the formation and expansion of this phenomenon. In this regard, the present study has been planned with the aim of monitoring and evaluating the effective factors in the development of gullies in the Haddam and Sharif watersheds of Khuzestan province. Modares Shushtar watershed, having Sharif and Hadam subwatersheds, as one of the important and typical basins of the province, every year a large area of its agricultural land is threatened by gully erosion.Materials and Methods In order to carry out this research, first, the parts with gullies in the study area were identified on the topography map with a scale of 1:250,000 during the 20-year period (1993-2012). Then, 15 gullies have been identified and investigated from each climate class of hot-dry desert and hot-semi-arid. Features such as the slope of the initial point of creating a gully and the slope of the front of the gully were calculated by the field method and using a tape measure, level and inclinometer measuring device and the mirage area of the gully front in the Google Earth softwave. Also, the physical and chemical characteristics of the soil of each gully were tested.Results and Discussion The results showed that the average percentage of bare soil above the head cut of selected gullies in Haddam and Sharif watersheds is 99.8% and 97.26%, respectively. Based on soil characteristics, the main cause of soil instability and erosion in gullies in both watersheds is EC. The morphometric characteristics of the gullies showed that in the Haddam watershed, all gullies are V-shaped in terms of cross section, and in the Sharif watershed, only gullies are B12, V-shaped and the rest are U-shaped. The Haddam watershed has the highest depth, width, and top of the gully compared to the Sharif watershed. The total volume of soil loss in Sharif and Haddam watersheds is 23000 and 51579 m3, respectively. Gullies A18 and B1 in Haddam watershed have the highest and lowest soil loss volume, at 11599 and 1612 m3, respectively. In the Sharif watershed, the maximum and minimum soil loss volume of gullies related to gullies A2 and B4 are 5282 and 369 m2, respectively.Conclusion and Suggestions The most important factors in the volume of soil loss and expansion of gulies are the characteristics of the watershed located upstream of the gully front (such as the extent and slope of the watershed) as well as the fineness of the geological formation (silt) and high soil salinity. Due to the excessive bareness of the soil, increasing the roughness of the soil surface with the establishment of vegetation is one of the compatible and low-cost methods in protecting soil resources. In order to control the spread of gully erosion, it is necessary to increase soil organic matter, modify saline and sodium soils with the use of modifiers, and also divert the runoff from the gully front.

Indian jujube displays genetic diversity and does not prominently display minute morphometric variations, and this makes correct identification a difficult and long-term task. However, little work has been conducted to bring jujube cultivars into domestication. So, the present study aimed to evaluate eleven cultivars of Indian jujube in terms of the fruit’s morphometric characteristics, as well as molecular marker studies by plastidial megakaryocyte-associated tyrosine kinase (matK) barcoding and inter-simple sequence repeats (ISSR) markers for species differentiation, identification, and relationships among Indian jujube cultivars. The results of the morphometric characteristics showed that the mean geometric diameter, surface area, sphericity, sphericity ratio, shape index, fruit length, fruit diameter, fruit weight, and seed weight varied among cultivars. The results also showed that the color values of L*, a*, and b* for fruits differed in different cultivars. In addition, the results showed a discrepancy in the genetic diversity parameters related to the matK barcoding, ISSR markers, and relationships among Indian jujube cultivars. Substantially, hierarchical clustering by heatmap revealed that ‘Zytoni’ and ‘Um-Sulaem’ with spines seem to be mono-clades distinct from other cultivars, which related to variations in the expression levels of genes. Therefore, they should be relied upon together to distinguish and identify cultivars in order to maximize the effectiveness of local germplasm conservation and exploitation.
