Identifying Conservation and Conflict Zones for Tibetan Brown Bears Under Climate Change Through Integrated Habitat and Prey Modeling on the Qinghai-Tibet Plateau. [PDF]
Ecol EvolThis study evaluates the future habitat dynamics of the Tibetan brown bear on the Qinghai‐Tibet Plateau under climate change by integrating predator–prey relationships and environmental variables using the MaxEnt model. Results show significant habitat contraction and shifting patterns, increasing the risk of human‐bear conflict.

High contributions of sea ice derived carbon in polar bear (Ursus maritimus) tissue
PLoS ONE, 2018 Polar bears (Ursus maritimus) rely upon Arctic sea ice as a physical habitat. Consequently, conservation assessments of polar bears identify the ongoing reduction in sea ice to represent a significant threat to their survival.

The impact of climate change on the structure of Pleistocene mammoth steppe food webs
, 2013 Species interactions shape predator-prey networks, impacting community structure and, potentially, ecological dynamics. It is likely that global climatic perturbations that occur over long periods of time have a significant impact on species interactions
