The Hazel Dormouse ( Muscardinus avellanarius) is commonly considered a typical lowland species, occasionally observed at higher elevations in mountain habitats. This study began with preliminary investigations the Gran Paradiso National Park Western Alps, where nests of Dormice were around 2000 m a.s.l. In 2019, mark-recapture project started two valleys (Valsavarenche and Val di Rhêmes), posi...

jajrood protected complex (khojir and sorkheh hesar national parks and jajrood protected area) is one of the most important habitats of central alborz wild sheep (ovis gmelini x o. vignei) in iran. since the species mate in fall, then fall home range has critical rule in life cycle of this species. using the ecological niche factor analysis (enfa), effective factors on the presence of species w...

Climate change might pose an additional threat to the already vulnerable giant panda (Ailuropoda melanoleuca). Effective conservation efforts require projections of vulnerability of the giant panda in facing climate change and proactive strategies to reduce emerging climate-related threats. We used the maximum entropy model to assess the vulnerability of giant panda to climate change in the Qin...

The local distribution of basking sharks in the Bay of Fundy (BoF) is unknown despite frequent occurrences in the area from May to November. Defining this species' spatial habitat use is critical for accurately assessing its Special Concern conservation status in Atlantic Canada. We developed maximum entropy distribution models for the lower BoF and the northeast Gulf of Maine (GoM) to describe...

Background and objectives: Climate change has been a serious issue in the last two decades and many studies have focused on its various aspects. Therefore, it is necessary to determine the future habitat of rangeland species present and future years, under climate warning models. In this regard, it should be investigated whether the increase in temperature will have a positive effect on the pre...

Winter dens are one of the important components of brown bear's (Ursus arctos syriacus) habitat, affecting their reproduction and survival. Therefore identification of factors affecting the habitat selection and suitable denning areas in the conservation of our largest carnivore is necessary. We used Geographically Weighted Logistic Regression (GWLR) and Generalized Linear Model (GLM) for model...

Habitat degradation is one the important reasons of plant species extinction. Modeling techniques are widely used for identifying the potential habitats of different plant species. Thus, the purpose of current study was to determine potential habitats of Zalzalak in Lorestan Province. Species presence data and 23 environmental variables were collected in Lorestan Province. Correlation analysis ...

One way that climate change will impact animal distributions is by altering habitat suitability and habitat fragmentation. Understanding the impacts of climate change on currently threatened species is of immediate importance because complex conservation planning will be required. Here, we mapped changes to the distribution, suitability, and fragmentation of giant panda habitat under climate ch...
