Animals, Journal Year: 2023, Volume and Issue: 13(5), P. 937 - 937

Published: March 5, 2023

Rapidly changing environmental conditions (bioclimatic, anthropogenic, topographic, and vegetation-related variables) are likely to alter the spatial distribution of flora fauna. To understand influence variables on Blue bull's identify potential conflict zones, habitat suitability analysis bull was performed using ensemble modeling. We modelled an extensive database current selected 15 ecologically significant variables. used ten species modeling algorithms available in BIOMOD2 R package. Among algorithms, Random Forest, Maxent, Generalized linear model had highest mean true skill statistics scores, ensuring better performance, were considered for further analysis. found that 22,462.57 km2 (15.26%) Nepal is suitable bull. Slope, precipitation seasonality, distance road contributing most Of total predicted habitats, 86% lies outside protected areas 55% overlaps with agricultural land. Thus, we recommend future conservation initiatives including appropriate mitigation measures should be prioritized equally both ensure species' survival region.

Gharial (Gavialis gangeticus) is one of the most highly threatened fauna fresh water ecosystems in world. Yet, information about species habitat characteristics influencing its distribution and threats to existence are still lacking Nepal. This study identified important associated with gharial presence existing Rapti River An opportunistic search method was adopted for field surveys conducted November December 2018. As part survey, Global Positioning System (GPS) coordinates were recorded each sighting location behavioral activity captured from photographic documentation. Habitat at stations spaced 500 m intervals along river addition locations where sighted. Data collected moving downstream on side (left right banks), which included both that comprised a total 200 sampling points. factors analyzed using combination MS Excel, ArcGIS R Binomial model logit link function.

Mugger crocodiles (hereafter called muggers) are the apex predator and keystone species in slow flowing freshwater ecosystem. They play an important role its functioning by distributing nutrients increasing primary productivity. Muggers have a sympatric distribution with gharials Rapti Narayani River of Chitwan National Park, but more research conservation attention has been focused on Nepal. The inadequate availability information occupied habitats muggers restrict their evidence-based management. Therefore, we investigated ecological factors affecting habitat selection threats River. We conducted preliminary survey, followed detailed February March 2022. During pre-defined characteristics were recorded at each station spaced 500 m intervals along river as well locations where sighted. used generalized linear model (glm) under binomial family logit link function to analyze influencing muggers. dependent variable was presence or absence sampling points independent variables included: bank aspect, width, mid-river depth, substrate type, slope, water current, invasive alien plant species, anthropogenic disturbances. In addition, relative whole-site ranking method employed determine most prevalent mugger. survey period, total 46 mugger individuals, 74% observed basking 26% submerged river. highest percentage (39.1%) sandy bank, grass forest (19.5%), clay (15.1%), respectively. Only banks moderate (15–25°) moderately steep (25–35°) slopes found be significant occurrence Fishing extraction materials, disposal garbage solid waste ranked threats.

The chital, Axis axis, constitutes one of Nepal's six deer species and maintains a closed population within the forest Institute Forestry, Hetauda Campus. Presently, chital faces range challenges, prompting comprehensive study encompassing status, habitat preference analysis, threat assessment. We utilized pellet group count method on 74 systematic random sample plots (4×4m) 100×100 m grid for estimation. Pellet presence/absence in predetermined characteristics was analyzed to assess preferences. Concurrently, relative ranking from household interviews employed evaluate existing threats. revealed total estimate approximately 141 individuals, with density 190 individuals per km2. Their showed an affinity towards areas abundant Sal riverine forests, along inclination locations further roads forested areas. Primary threats encompassed attacks feral dogs, illegal hunting, degradation mainly due invasive alien plant species. This shows that effective management mitigation strategy control hunting help local authorities, improving conditions concerning their preferences, has potential continue growing coming years.
