Impact of global change on the distribution of mountain mammals and birds
Conservation Biology, EarlyView.Abstract Climate change and land‐use changes are key drivers of global biodiversity loss. Many species are shifting to higher elevations or latitudes in response to global warming, often encountering unfavorable land‐use conditions during the shift. These changes can lead to reduced range size and increased extinction risks, particularly for mountain ...
