Biogeography is the study of the distribution of animals.

Introduction to Wildlife Corridors

Wildlife corridors are overpasses and underpasses that connect natural regions and provide safe transit for migratory animals through human infrastructure.

Scientists are now worried that the future of the 17,000 wolves known to live in Europe is in jeopardy due to crossbreeding with dogs.

The National Weather Service in Miami recently issued a "falling iguana" warning during a cold spell.

Why Do Iguanas Drop From Trees When It’s Cold in Florida?

Occasionally, the temperature in southern Florida approaches freezing, leading to falling iguanas.

An analysis of 24 years of radar data shows a shift to earlier spring migrations, particularly for birds at higher latitudes where regions are warming more quickly. Figure: Horton et al., 2020.

Spring Bird Migration is Happening Earlier for Some Birds

With changes in temperature due to climate change, researchers looking at  24 years of radar data from the National Oceanic and Atmospheric Administration (NOAA) have found that migrating birds were more likely to arrive at certain stops earlier than they would have twenty years ago. 

Researchers analyzed Landsat satellite imagery between 1993 to 2018 to look at changes in subnival vegetation cover in the Himalayas.

Plant Life is Expanding in the Area around Mount Everest

Using satellite imagery, researchers have found that subnival vegetation, the vegetation that grows between the treeline and snowline, is increasing in spatial extent around the Mount Everest and Himalaya area.
