Low oil concentrations impact Gulf fish, Jellyfishes’ rising ecosystem status and the importance of bees

Miniscule oil amounts, major biological ramifications for fish: Trace amounts of oil from a spill can have harmful and lasting biological effects, according to Andrew Whitehead, a biologist with the Louisiana State University (LSU). Whitehead, along with Fernando Galvez (also an LSU biologist), led a study examining the biological effects of low concentrations of oil on fish in the Gulf of Mexico.  Their research has previously shown...

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...

Ecological research in images

(Click the below image to view the photo gallery.) This week, the American Museum of Natural History launched the exhibit “Picturing Science: Museum Scientists and Imaging Technologies” which explores the images produced by scientists while performing research. The images range from bug genitalia to staghorn coral (see video at the end of this post). As quoted in a recent Wired Science article, “‘A lot of people come to the museum...

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...
