A new study published in Animal Behaviour found that bottlenose dolphins in Sarasota Bay, Florida, that engage in risky human-centric foraging behaviors, such as taking bait or catch from fishing gear, scavenging discarded bait or fish, or approaching humans for food tend to associate more with other dolphins that use similar tactics. The study also found that severe harmful algal blooms, commonly known as red tides, altered the relationship between these foraging behaviors and dolphin social structure. 

The research was led by Kyra Bankhead of Oregon State University, with co-authors Mauricio Cantor of Oregon State University, Katherine McHugh and Randall Wells of the Sarasota Dolphin Research Program, which is operated by Brookfield Zoo Chicago. 

A deadly combination of fungal, parasitic and bacterial infections could push certain species of snakes toward extinction, according to new research from the University of Georgia.
