Estimating the population density of organisms is of great concern to ecologists and much effort has been put into making accurate assessment of population levels in nature. We evaluated the trapping web (TW) method for the determination of the density of species of burying beetles. We found eight and six species of burying beetles at Beopjusa and Ssanggok‐ri areas, respectively. Most of the species population comprised Nicrophorus quadripunctatus, with densities of 65 and 195 per ha for Beopjusa and Ssanggok‐ri areas, respectively. Moreover, the flight intercept trap (FIT) method from 2003 to 2007 also revealed the same trend: Beopjusa temple (2928) to Ssanggok‐ri (5835). However, the differences in number of individuals were probably due to the differences in the methods and the length of the trapping period. The populations of N. quadripunctatus exist as metapopulations, making accurate assessment of the population densities extremely difficult. We hypothesized that the TW method could accurately estimate population densities extrapolated from patch population size per area. [ABSTRACT FROM AUTHOR]

This study aimed to establish the best applicable method for the National Ecosystem Survey (NES) guidelines by (i) verifying the efficiency of an insect trap that combined the Malaise trap, flight intercept trap, and pitfall trap (MFP trap) as part of the improvement for the terrestrial insect field in the fifth NES, and (ii) comparing the result with the currently used Malaise trap and pitfall trap (MP traps). We found that the efficiency of attaining species diversity was much higher with the added flight intercept trap function than the current Malaise trap alone for flying insect collection. For collecting ground insects, the efficiency of attaining species diversity of the pitfall trap from the MFP trap was lower than that from the MP trap. Besides, the Malaise trap of the MP trap showed superior efficiency than that of the MFP trap in species diversity. The results suggested that modification, supplementation, and re‐testing should be performed by analyzing various factors such as the trap material, barrier size, capturing container inlet, and mesh size, with consideration of the design of the current Malaise trap. Therefore, in survey‐based research, which aims at identifying insects species diversity and inhabiting status—such as the NES, it is necessary to introduce the MFP trap with the flight intercept trap function added to the Malaise trap function, and for the pitfall trap function of the MFP trap, it can be operated as a separate trap from the MFP trap.

One conclusion of this study is that as the road network expands in rural and remote areas the surrounding butterfly populations are generally noted to be decreasing or even disappearing. However, there is one exception, Libythea celtis. This common species, living close to forested areas, have actually increased while thier competing species have decreased according to this study. The endangered species of Korea, Parnassius bremeri, Sinia divina and Argynnis nerippe, which inhabit the area of the study have also decreased or disappeared. Another result of this study is that, while the number of species which inhabit the grasslands have decreased, no similar changes have been noted in the number for the species which inhabit the shrubs. Furthermore, there has been a growth in the numbers of the species that inhabit trees. In addition, the number of individuals has decreased in the grasslands and shrubs but increased in the trees. Overall, the general conclusion of this study is that, while the development of rural and remote areas showed a decrease in the number of specific butterfly species, they are being replaced by more common species.

Hipparchia autonoe, designated Natural Monument no. 458, is a species inhabiting Mt. Halla on Jeju Island, which is the only habitat of H. autonoe in South Korea. Recently, this species is in danger of extinction as the population has been remarkably reduced because its host plants and nectar plants are gradually disappearing due to plant succession in its habitat. On the climbing road of Jeju Island Eorimok, H. autonoe used to be observed at and above 1300 m a.s.l. However, since Sasa quelpaertensis has recently expanded its habitat up to 1400 m, H. autonoe is now observed at and above 1500 m. In Mongolia, the population of H. autonoe seems quite stable as there are dense populations of a host plant and nectar plants. Accordingly it is judged that we can maintain a stable community for support of H. autonoe if we successfully manage the host plant and nectar plant communities by controlling the density of S. quelpaertensis using biological and physical control methods. Comparative analysis of DNA barcode region of COI (658 bp) was done to check the homogeneity and the genetic diversity of H. autonoe collected in Korea and Mongolia. The DNA sequence difference among individuals collected in South Korea was 0.0-0.2%, and in Mongolia 0.0-1.4%. This confirmed a 0.06-1.2% barcoding gap. We believe that this result will provide basic information useful to guide conservation of H. autonoe in South Korea. [ABSTRACT FROM AUTHOR]

Endoparasitoids of Anomis privata larvae include five species in three families of two orders. In this work, two species of Hymenoptera Braconidae ( Cotesia sp., Microplitis sp.), one species of Ichneumonidae ( Mesochorus vittator) and two species of Diptera Tachinidae ( Exorista ( Podotachina) sorbillans, Timavia amoena) were investigated. Of the 261 larvae of A. privata examined, 32 had a parasite, so the rate of parasitism was 12.26%. Parasitism by taxon was the highest, at 10.35% (27 individuals), in Cotesia sp. in Hymenoptera Braconidae. Parasitoids of Braconidae and Ichneumonidae were larval parasitoids. A parasitic insect of Tachinidae was a larva-pupal parasitoid. Solitary parasitoids included Microplitis sp. in Braconidae and E. sorbillans in Tachinidae. Gregarious parasitoids included Cotesia sp. in Braconidae, M. vittator in Ichneumonidae and T. amoena in Tachinidae. There was also a multiparasitoid ( T. amoena) and two superparasitoids ( Cotesia sp., M. vittator). A larva of A. privata sought feed even after it was parasitized every parasitoid investigated in this study, so five species of parasitoids were all koinobiont. [ABSTRACT FROM AUTHOR]

Background: This study examined the effects of systemic vibration exercises on cerebral palsy patients., Methods: Literature published in Cumulated Index to Nursing and Allied Health Literature (CINAHL), Cochrane library, Embase, Physiotherapy Evidence Database (PEDro), and PubMed was reviewed. A total of 2978 studies were initially retrieved. After further reading of the full texts 17 articles were finally included. A quality assessment of the included studies was conducted using the risk of bias (RoB) 2.0, and the Funnel plot and the Egger test were conducted to confirm the publication bias. Subgroup analysis was carried out according to the dependent variables, the international classification of functioning, disability, and health (ICF), frequency, treatment period and age., Results: The overall effect size of homogeneity was 0.474 (CI = 0.148-0.801). The analysis of the dependent variables showed the following order of the effect size: balance, muscle strength, spasticity, bone density, range of motion of the joint, gait function, and motor function. In the ICF classification, the effect size was observed to follow the order of body structure and function, activity, and participation. The effect size in the intervention according to the treatment period showed the following order: 7 to 12 weeks, 1 to 6 weeks, and 14 to 24 weeks. The age-dependent classification showed the following order in the effect size: school age, adolescent and adult, and infant and school age., Conclusions: Systemic vibration is the most effective intervention to improve the balance and gait in patients with cerebral palsy and improve the body structure and function according to the ICF., Competing Interests: The authors have no conflicts of interest to disclose., (Copyright © 2023 the Author(s).

The purpose of this review was to analysis the effects of treadmill training on gait function in children with cerebral palsy. Cumulative Index to Nursing and Allied Health Literature (CINAHL), Cochrane Central Register of Controlled Trials, Physiotherapy Evidence Database (PEDro), PubMed and Web of Science were searched. Investigating the effects of treadmill training on gait endurance, gait speed, limb support time, cadence, and step length in children with cerebral palsy. Similar outcomes were pooled by calculating the standardized mean difference. Of the eight studies, 179 participants were included. The average PEDro score was 6.25/10. The results of the sensitivity test for bias evaluation using the duval and tweedie's trim and fill method showed low publication bias. The test regarding the effect of treadmill training on overall gait function yielded a moderate effect size of 0.53, which was a statistically significant effect as its confidence interval did not include. The overall effect size of gait endurance was 0.85. The overall effect size of gait speed and limb support time were 0.52 and 0.73. The overall effect size of cadence and step length were 0.14 and 0.21, indicating a nonsignificant improvement. These findings suggested that treadmill training on cerebral palsy was effective for gait endurance, gait speed and limb support time than cadence and step length., Competing Interests: CONFLICT OF INTEREST No potential conflict of interest relevant to this article was reported., (Copyright © 2020 Korean Society of Exercise Rehabilitation.)

The purpose of this pilot study is to examine the immediate effect of interventions based on the frequency of whole-body vibration on children with cerebral palsy's balance and walking abilities. A total of 12 were selected as subjects. All subjects measured 10-m walking test (10MWT), Timed Up and Go (TUG) test and measured sway length (SL) and limit of stability (LOS) by bio-rescue. And those were performed again after the frequencies of the 12, 18, and 26 Hz were applied respectively. To check the immediate effect, all subjects performed only one frequency of interventions per day and no other treatment was performed in parallel to control the foreign variables. After intervention, 10MWT were significantly increased in the 12 and 18 Hz groups ( P <0.05). TUG test and LOS were significantly increased in the 18 Hz group ( P <0.05). There were no significant differences on TUG, SL, and LOS in the 12 Hz group. There were no significant differences on 10MWT, TUG, SL, and LOS in the 26 Hz group. Looking at the results of this study, the immediate effect of whole-body vibration shows that the frequency of the 18 Hz group is the most effective interventions in promoting walking and balancing abilities in children with cerebral palsy than frequencies of the 12 and 26 Hz groups., Competing Interests: CONFLICT OF INTEREST No potential conflict of interest relevant to this article was reported.
