Social immunity of bees

by Liza Lester, ESA communications officer A honey bee (Apis mellifera) afflicted with Varroa destructor, a parasitic mite that sucks away its vital, blood-like hemolymph, often passing along viruses in the process, and leaving open wounds. The mite spreads by bee-to-bee contact, accelerated by yearly circuits of agricultural bee broods transported to pollinate almonds and blueberries and other crops. Varroa is a suspect in the still...

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...

Pollination from the plant’s perspective

If plants had a perspective, they would probably think of pollinators as more than just extra-friendly house guests. That is, plants would be more likely to view pollinators as the mutual friend who likes to set up blind dates. Bees might limit pollen to its use as a protein source for the hive, and birds might devour the flesh of a fruit and eliminate the seed as waste. However, many flowering plants, as Bug Girl pointed out in a...
