Abstract Seven hundred and twenty four fish specimens were captured from March to September 2016. The materials used in the current study were cast nets, hand nets. Eight cyprinid fish species were studied for their length-weight relationships. Parameter b in the LWR was 3.03, 3.06, 3.02, 2.29, 2.82, 3.43, 2.73 and 2.47 for Schizothorax plagiostomus, Schizothorax esocinus, Racoma labiata, Tor putitora, Barilius vagra, Garra gotyla, Puntius ticto and Arassius auratus respectively. Current study is the first attempt on the LWRs of cyprinid species, provide a baseline approach for conservation and /management of local fish fauna of economic importance.

Abstract Feral dogs are well-organized hunters of ungulates in many parts of the world, causing great damage to wildlife populations and ultimately to the ecosystem. In Pakistan, the impacts of feral dogs on the wildlife have not been documented yet. In a period of fifteen years (2006-2020), feral dogs have killed hundreds of threatened markhor in Chitral gol national park (CGNP), Pakistan. Despite direct predation other impacts including disturbance and competition with other natural predators, could compromise conservation and management efforts. The population of feral dogs seems to have been increased with the increase of dumping sites by communities. Our findings suggest that there are pressing needs of controlling the feral dogs population and eradicating them from the core zone of CGNP and surrounding buffer communities. Conventional culling of dogs should be coupled with modern techniques like castration and sterilization. Communities should be educated regarding the clean environment, proper disposal of home wastes and, biodiversity conservation.

The species diversity and abundance of wildlife are the important indicators of a healthy ecosystem. A survey-based scientific study on species diversity, abundance and status of vertebrate wildlife was conducted from May 2015 to April 2016 at Sreepur upazila, Magura, Bangladesh. A total of 123 species of vertebrate wildlife was recorded during the 12 months of study period. Among them, eight species (6.5%) were amphibians, 13 (10.57%) reptiles, 84 (68.29%) birds and 18 species (14.64%) were mammals. Out of 84 species of birds, 45 (53.57%) were passerines and 39 (46.43%) non-passerines. Most of the observed birds (72 species, 85.72%) were resident and the rest 12 species (14.28%) were migratory. The highest number of wildlife species was observed in winter (108 species, 87.80%), particularly in December (62 species, 50.40%). The lowest number of species was recorded in June (33 species, 26.83%). Out of 123 species of vertebrate wildlife, three (2.44%) were very common, nine (7.32%) common, 26 (21.14%) fairly common and 85 (69.1%) were common. Of the total species, 117 (95.12%) species were least concern, five (4.06%) near threatened and one (0.81%) was endangered according to IUCN Bangladesh 2015. Implementation of conservation and management plan is required to save the wildlife in the study area. J. Biodivers. Conserv. Bioresour. Manag. 2021, 7(1): 51-62

Historically the study of diet caribou and reindeer (Rangifer tarandus (Gmelin, 1788)) has been specific to herds and few comprehensive circumpolar analyses of Rangifer diet exist. As a result, the importance of certain diet items may play an outsized role in the caribou diet zeitgeist, e.g., lichen. It is incumbent to challenge this notion and test the relevant importance of various diet items within the context of prevailing hypotheses. We provide a systematic overview of 30 caribou studies reporting caribou diet and test biologically relevant hypotheses about spatial and temporal dietary variation. Our results indicate that in the winter caribou primarily consume lichen, but in warmer seasons, and primary productivity is lower, caribou primarily consume graminoids and other vascular plants. In more productive environments, where caribou have more competitors and predators, consumption of lichen increased. Overall, our description of caribou diet reveals that caribou diet is highly variable, but in circumstances where they can consume vascular plants, they will. As climate change affects Boreal and Arctic ecosystems, the type and volume of food consumed by caribou has become an increasingly important focus for conservation and management of caribou.
