Abstract Extensive field surveys were carried out to explore the distribution of Leisler’s Bat Nyctalus leisleri (Kuhl, 1819) in selected area of FATA regions, Pakistan. Specimens of Leisler’s Bat Nyctalus leisleri (Kuhl, 1819) (n5) were collected from Kurram Agency (Shublan) (N33.8229788 E70.1634414) at elevation 1427m and Khyber Agency (Landi Kotel) (N34.0909899 E71.1457517) at elevation 1091m for two years survey extending from May 2013 through August 2015. The mean head and body length, hind foot length, ear length and tail length the Nyctalus leisleri specimens captured from the study area was 65.08 ± 1.58 mm, 44.06 ± 0.52 mm, 8.38 ± 0.60 mm, 13.20 ± 0.99 mm and 39.46 ± 1.46 mm, respectively. For molecular analysis the sequences of COI gene were obtained and analyzed. The mean intraspecific divergences of Nyctalus leisleri was 0.04%. The mean interspecific divergences of Nyctalus noctula and Nyctalus leisleri was 0.2%. The mean concentration of each nucleotides was A = (26.3%), T = (32.8%), G = (15.9%) and C = (25.0%). The mean A+T contents were 59.2%and C+G were 40.9%. In the phylogenetic tree Nyctalus leisleri and Nyctalus noctula clustered with significant bootstrap support value.

The increasing international grain trade make it necessary to have more deep facilities for large draught ships. Within the areas of major agriculture developments, Bahia BIan ca harbour complex, is one of the most important and consequen (;ly also its improvement. In order to achieve this improvement a deeper and wider navigation channel has to be designed. The actual channel, 100 km. long is limited to bulk up to 37 ft. draught. It is developed along a sandy coast with large bars and islands. Bahia Blanca is the southwest of the Buenos Aires Province, within trapezoidal shape, where the mean tidal range chang m in the inner part to 1,8 m in the outer part. Try prove a so long channel in a complex sedimentologic imply a rather difficult task, which requires a ful gation programme to achieve an economical and techn tion. To this end, extensive field and desk studies ed out covering all the influence area and testing altematives . . carriers and silty located at a Bay of es from 3,5 ing to imal area . ly investiical so luwe re carri different One of the major problems to solve is the sedimentological sta bility of the channel due to the action of currents and waves. The use of mathematical models and of large and reliable field surveys, together with a pilot test dredging used as a one to one model for the calibration of the transport formulas, looks as the most suitable method to attack such problems. The results of this study are part of the navigation channel project carried out by the firm NEDECO-ARCONSULT for the Argen tine Government.

Lower Mobility

The long-tailed goral (Naemorhedus caudatus) is a critically endangered herbivore in South Korea. Despite government efforts to recover the population through reintroduction programs, the animal remains vulnerable to heavy snowfall. From March to June 2010, 24 animals were found dead due to heavy snowfall in the Wangpi Stream basin. In this study, we hypothesized that gorals that died due to snowfall are low-status individuals that lived in the sub-optimal or non-suitable areas. Using the occurrence data from extensive field surveys from 2008 to 2010 in the Wangpi Stream and the carcass location data, we (1) defined the goral habitat characteristics and (2) compared the habitat characteristics between dead and living gorals using ensemble species distribution modeling. The results suggested that the sites where dead gorals were found were highly related to typical goral habitats. These results implied that the optimal goral habitats could become uninhabitable following heavy snowfall. Most of the dead animals were pregnant females or were young, implying that they could not escape their primary habitats due to lower mobility. Thus, when there is a climate catastrophe, the optimal goral habitats should be considered for rescue and artificial feeding.

Extensive field surveys of the Critically Endangered Central and Eastern Rûens Shale Renosterveld have uncovered that Notobubon striatum, as currently circumscribed, comprises two distinct species. Upon careful examination of the type material it has become clear that names exist for both species. The type specimen of N. striatum clearly matches the lesser known species, a large shrub, ca. 1 m. tall, with a powerful anise-scent and which is restricted to the banks of seasonal rivers and watercourses in the Central and Eastern Rûens Shale Renosterveld. The second and better known entity, with a wider distribution, corresponds to the type material of Dregea collina Ecklon & Zeyher. As such, a new combination, Notobubon collinum (Ecklon & Zeyher) Magee, is here made to accommodate this taxon, restricted to dry quartz and silcrete patches or outcrops in Eastern Rûens Shale Renosterveld. In their revised circumscriptions N. striatum and N. collinum are readily distinguished by habit, scent, leaf size and division, as well as leaf lobe shape and sepal size. Comprehensive descriptions of both species are provided, together with notes on their ecology and conservation status, and the existing key to the species of Notobubon updated. This brings the number of recognised species in the genus to thirteen.

Glacial Relict

The Pannonian root vole Alexandromys oeconomus ssp. mehelyi represents a rare glacial relict, whose occurrence is nowadays bound to several areas in Europe. Four somatic and 25 craniological features were analysed, based on 355 measured specimens. Sex is a significant factor affecting the average value of all four somatic features, where all of them achieve higher values in males than in females. While body length and tail length were also affected by seasons, body weight and the length of the hind foot were stable features present across the seasons. In cranial features, the largest variability in the adult population is characterised by neurocranium breadth (LaN), total length of the cranial base (LB), and skull (LCr); whereas the smallest variability of the cranial dimensions is reflected in the values of the greatest palatal breadth (PS) and postorbital breadth (Io). Calculating the weight from cranial remains may be used to estimate the size of the prey and to determine vole biomass consumed by predators, such as raptors, highlighting the utility of studying feeding ecology.

We adopted DNA barcoding technique using a 658-bp fragment of the mitochondrial cytochrome c oxidase I (COI) gene to identify shrimp species collected from the different areas of Bangladesh. A total of 24 sequences were generated belonging to 14 species including four new records- Macrobrachium nipponense, Macrobrachium kistnense, Exopalaemon carinicauda and Alpheus malleator. Genetic distance measured with Kimura 2 parameter showed that genetic divergence increased with higher taxonomic rank. The mean genetic divergence was evaluated and found to be 0.935%, 22.67% and 30.92% within species, genus and family, respectively. In addition to the barcode-based species identification system, phylogenetic relationships were established where individuals belonging to the same species were grouped under the same clade. Maximum likelihood (ML) was preferred as the statistical method and as expected, the phylogenetic tree complemented and ensured the conventional taxonomy. The present study evidently showed that DNA barcoding can be served as an effective tool to discriminate the shrimp species and this will enhance the understanding on evolution and conservation biology.

The aim of current study is to provide a significant traditional knowledge on wild medicines used for ethnoveterinary purposes in the rural area of Maraog region in district Shimla. The medicinal plants have played a significant role in the treatment of human as well as animal’s diseases. The rural people of the Maraog region were interviewed through a questionnaire and extensive field surveys were conducted from June 2020 to July 2021. The discussion, observations and interviews were conducted in study site and included 96 informants. The information gathered from the residents is presented in a table format and includes scientific and local names, different parts used, diseases treated and mode administration. The most commonly used taxa are calculated with used value. The study revealed 100 plants in which trees (7), shrubs (26), herbs (56), ferns (5), grasses (3) and climbers (3) were identified. The most commonly documented livestock diseases were found to be hoof infections, eyes infections, poisoning and skin infections. In the current study, the Rosaceae family was reported as being the highest number (11), followed by Asteraceae (10) and then Lamiaceae (6). It was found that leaves, roots, flowers and fruits are the commonly used parts for ethnoveterinary medications. The phytochemicals present in the plant, such as alkaloids, sterols, glycosides, flavonoids, lignin, coumarins and terpenoids, etc., may be responsible for their medicinal properties. In this documentation, it was observed that the younger generation does not have good knowledge of medicinal plants as compared to the older ones. Therefore, it is necessary to preserve the traditional knowledge of these medicinal plants before their permanent loss. The documentation and conservation of medicinal plants can be a good start for novel phytopharmacological research in the veterinary field.

Abstract: Postnatal growth and development of the small Neotropical mouse Oecomys rutilus (Sigmodontinae: Cricetidae) were investigated from birth to day 143, in the laboratory. Morphometric measurements at age of 3 days, of both sexes combined, revealed body weight to be 3.4 ± 0.3 g, mean tail length as 27.4 ± 1.1 mm, and mean hind foot length as 9.3 ± 0.7 mm. Body weight was found to increase steadily until at least 69 days, whereas the instantaneous growth rates of other measurements declined earlier: the daily growth of hind foot length declined to a minimum at age of 24 days, and the growth of tail and of ear declined by the age of 33 days. Average litter size for 12 captive births was 2.5, ranging from 2 to 3. The preserved eye crystalline lens was weighted in 23 captive-born animals of known age, allowing a rough estimate of the age of reproduction in wild-caught animals. Based on the inferred relation between eye-lens weight and age, the youngest reproductive (pregnant) wild-caught females had an estimated age of 90 and 95 days.
