Life on Earth is undergoing its sixth ever mass extinction, one that is entirely driven by humans. Amongst the multitude of “global change” factors causing species’ extinctions, climate change and the loss and degradation of natural habitats are major causes. This is especially the case for species in tropical mountain ranges, where most of Earth’s terrestrial biodiversity is concentrated, and where species tend to be thermally sensitive. Umesh Srinivasan and his team study how forest degradation combines with climate change to impact Himalayan biodiversity at multiple levels, from geographic range shifts to behaviour and demography. Their main ongoing work is in the eastern Himalayas of Arunachal Pradesh, where they have been monitoring bird populations in primary and logged forests for a decade using mist netting and bird ringing. They combine this with behavioural observations to understand how climate change and forest loss are altering the composition of mixed-species bird flocks across the elevationa
