Tracking Pacific walrus, impacts of early-life stress, and plant traits matter more than origin

Monitoring Pacific Walrus: With the end of summer fast approaching, US Geological Survey (USGS) researchers are once again gearing up to radio-tag walruses on Alaska’s northwestern coast as part of the agency’s ongoing study of how the marine mammals are coping with declining sea ice. “Sea ice is an important component in the life cycle of walruses.  These tracking studies will help us to better understand how top consumers in the...

Hybrids in the Arctic

Hybridization has led to some of the unique, naturally-occuring species present today, such as the Mallard duck-American Black duck hybrid. Usually this natural process takes generations to produce a new distinct species; however, it is possible for hybrids to emerge within one generation. For example, interspecies breeding could be expedited due to environmental stressors caused by climate change. Species that would not normally come...

Immersed in the clouds: Interview with tropical cloud forest researcher

There is a world within the canopy of a tropical cloud forest that not many people get to see. In this unique ecosystem—maintained by the exceptionally wet microclimate of cloud cover—orchids, moss, lichens and other epiphytes grow in every crease and pocket of the supporting tree branches. Here, hundreds of species of birds, along with monkeys and other mammals navigate the aerial landscape, scattering seeds along the way (see below...
