In contrast to medical education, information on the use of arts as a learning approach is scarce in veterinary anatomy. The aim of this prospective, questionnaire-based study was to survey students' use of drawing in various aspects of veterinary anatomy learning (self-study, examinations, preparation for, and reflection on cadaver dissection). The quantitative data showed that first-year students with artistic preferences used drawing significantly more often in most aspects of anatomy learning than students with no such preferences, apart from the reported use of drawing in examinations and for reflection after cadaver dissection. The lack of significant correlations of the reported use of drawing in examinations with any other study variable provided support for the author's observation that student-generated drawings are not as commonly used in examinations as previously. In contrast to the study hypothesis, previous university studies did not correlate significantly with any aspect of the use of drawing in anatomy learning. None of the reported uses of drawing addressed the benefits of drawing in learning the comparative anatomy of animal species, a characteristic distinguishing veterinary anatomy from human anatomy. Qualitative student feedback indicated that encouragement and teacher-produced images would increase the use of drawing as a learning approach even if the implementation of drawing into the curriculum is not feasible. Conclusions from this study were implemented through self-directed learning in anatomy courses that replaced the canceled cadaveric dissections during the COVID-19 outbreak and also through the ongoing drawing workshops to further advance the use of drawing in veterinary anatomy learning.

The endangered Saimaa ringed seal (Pusa hispida saimensis) is an endemic freshwater subspecies inhabiting Lake Saimaa in Finland. The Baltic ringed seal (Pusa hispida botnica) inhabits the brackish Baltic Sea, which is almost entirely landlocked. Recent research shows that Saimaa and Baltic ringed seals may be genetically even further apart from each other than from other ringed seal subspecies. We documented histologically the integument microstructure of Saimaa and Baltic ringed seals to determine whether the geographic and genetic isolation was manifested as variation in the integument microstructure of these subspecies adapted to icy aquatic environments. The skin structures of these subspecies were similar to those of other phocids. The association of the sweat glands with hair follicles in both subspecies suggested that they were small apocrine sweat glands described previously in terrestrial or aquatic mammals. None of the apocrine glands had large lumina, and some of the ducts were relatively straight and short. Further studies analysing the mode of secretion, for example, apocrine versus eccrine, in the sweat glands are necessary to confirm the types of sweat glands in seals. [ABSTRACT FROM AUTHOR]

Collaborative learning has been used in anatomy courses to support students' learning of challenging topics but the success of group work depends significantly on the students' ability to communicate in a professional manner. Veterinary students' experiences with tasks related to collaborative learning and professional conduct were studied by comparing learning collaborative competences and pedagogy, as well as perceived positive and challenging aspects, in two gross anatomy courses. Both qualitative and quantitative data were collected from students' experiences of course assignments and collaboration, as well as from self-evaluated collaboration competence development. Trying things out oneself, practical application and professional conduct were positively highlighted particularly in the first-year course (myology and arthrology) group work and learning from others more in the second year (topographical anatomy). Various group work challenges, often relating to practical matters or communication, were the key concerns for students. The main difference between the two courses in learning of collaborative knowledge work competencies appeared to relate to the nature of the group work assignment. The topography course included the element of collaboration in preparing a presentation and teaching session for the rest of the class. Interestingly, students on the myology and arthrology course gave more positive comments on professional conduct than the students on the topography course despite the fact that the latter course included more practical elements relating to their future profession.

The various models used in gross anatomical studies to improve the visualization of blood vessels differ in the amount of manual labour, cost, equipment and time involved. This study aimed to compare chemical and enzymatic maceration processes for soft‐tissue removal from arterial silicone casts on skull scaffolds using ringed seal (Pusa hispida) skull specimens. Both processes produced specimens that covered all anatomical aspects required to visualize the intracranial arterial arrangement on a bone scaffold. Overall, the enzyme maceration process was better for production of such specimens, as this process is easy and safe to perform, is less harmful to the bony parts of the specimen, and the resulting specimens are visually more appealing for display and teaching. Compared with previously published models, the end result varied in the amount of dissolved bone tissue and the visual presentation of the model. [ABSTRACT FROM AUTHOR]

The anatomical architecture of the hip and stifle joints of the Saimaa ringed seal was determined by dissection to be similar to that of the Baltic ringed seal. There was no ligament of the femoral head in the hip joint. The lateral side of the stifle joint lacked a collateral ligament but the collateral ligament on the medial side was of considerable size. The medial meniscus was larger and thicker than the lateral meniscus. The asymmetrical anatomical architecture allows for much lateral movement during aquatic motion, but it is poorly adapted to terrestrial locomotion. [ABSTRACT FROM AUTHOR]

We examined home range size and habitat use of nine female northern myotis (Myotis septentrionalis) within an intensively managed forest in the central Appalachians of West Virginia. Using the 95% adaptive kernel method, we calculated a mean home range of 65 ha. Northern myotis used recent diameter-limit harvests and road corridors more than expected based on availability of these habitats. Intact forest stands and more open deferment harvested stands were used less than expected based on the availability of these habitats, although intact forest stands still constituted the overall majority of habitat used. Partial timber harvests that leave a relatively closed canopy appear to promote or improve northern myotis foraging habitat in heavily forested landscapes. However, the long-term ecological impacts on bats and other biota from this silviculturally unacceptable practice are unclear.

Abstract Hantavirus genome sequences were recovered from tissue samples of Myodes rufocanus, Microtus fortis and Microtus oeconomus captured in the Baikal area of Buryatia, Russian Federation. Genetic analysis of S- and M-segment sequences of Buryatian hantavirus strains showed that Myodes-associated strains belong to Hokkaido virus (HOKV) type while Microtus-associated strains belong to Vladivostok virus (VLAV) type. On phylogenetic trees Buryatian HOKV strains were clustered together with M. rufocanus- originated strains from Japan, China and Far-East Russia (Primorsky region). Buryatian Microtus- originated strains shared a common recent ancestor with M. fortis- originated VLAV strain from Far-East Russia (Vladivostok area). Our data (i) confirm that M. rufocanus carries a hantavirus which is similar to but distinct from both Puumala virus carried by M. glareolus and Muju virus associated with M. regulus, (ii) confirm that M. fortis is the natural host for VLAV, and (iii) suggest M. oeconomus as an alternative host for VLAV.

Abstract Sixty one tissue samples from several rodent species trapped in five provinces of Thailand were examined for the presence of hantaviral markers by enzyme-immunoassay and immunoblotting. Four samples, all from the great bandicoot rat Bandicota indica, were confirmed positive for the hantaviral N-antigen. Two of them were trapped in Nakhon Pathom province, the other two in Nakhon Ratchasima province, approximately 250 km from the other trapping site. When analysed by RT-nested PCR, all four rodents were found positive for the hantaviral S- and M-segment nucleotide sequences. Genetic analysis revealed that the four newly described wild-type strains belong to Thailand hantavirus. On the phylogenetic trees they formed a well-supported cluster within the group of Murinae-associated hantaviruses and shared a recent common ancestor with Seoul virus.

As part of our research aiming to understand the morphological variation in ringed seals, we dissected mastication muscles of nine Saimaa ringed seals and two Baltic ringed seals. We found no significant differences in the muscles of mastication between these subspecies but the location of the tympanic bulla in relation to the articular surface of the temporomandibular joint was more medial in the Saimaa ringed seal. As compared with the previously studied Baikal and Caspian seals, the origin of the jaw-opening digastricus muscle covered less of the tympanic bulla in the Saimaa and Baltic ringed seals. Our data on masticatory-muscle masses indicated that similarly to terrestrial mammal species, the growth patterns of mastication muscles of the Saimaa ringed seal differed from each other according to the body size.
