Read how the tarantula hawk transforms from a mean stinger to an invertebrate villain of science fiction proportions.
Sunday Sketch: Blood Sharing Bats
As their name suggests, vampire bats need to consume blood often to stay alive. Female vampire bats roost in groups, and when some bats aren’t able to get a meal, others in the same group will regurgitate their own meals to share! Research revealed that females who shared meals with an extensive network of nonrelatives…
Field Frame Friday: Grazing or lazing
Beef cattle (bos taurus) display individual differences in grazing behavior on rangelands such as those in California. Even same-breed cattle can exhibit a variety of grazing patterns, such as traversing more terrain, traveling further from water, and climbing higher elevation than their fellow herdmates.

Sunday Sketch: Learning to pick your battles
Northern elephant seal harems (Mirounga angustirostris) are a cacophony of noises with males vocalizing at each other and occasionally getting into physical battles; what information is coded within those noises? Researchers at University of California, Santa Cruz used playback experiments (i.e. recording vocalizations and then playing the vocalizations back to other individuals) to discover that…

Navigating the zoo debate: what we thought was black and white is actually gray all over
When approached to write an article highlighting zoos and aquariums, I did not hesitate to say yes, as zoos and aquariums have defined my career interests. However, brainstorming has been an overwhelming process, as there are so many directions this article could take. Should it highlight the history of zoos, and how they are evolving…
Field Frame Friday: How do you like your eggs?
Due to warmer temperatures, egg incubation in tropical birds presents a different set of challenges than temperate species. To regulate temperatures, lesser noddies (Anous tenuirostris) will rotate the egg around the nest every 50 minutes, and when ambient temperatures get above 30℃ (86 ℉) , parents will actually lift off of the egg, and depend…
Newsroom: Counter culture
Does social learning help or hinder adaptive response to human-induced rapid environmental change? Human-induced rapid environmental change (HIREC), such as climate change, habitat fragmentation, and pollution, poses a potential threat to a variety of wildlife species. If or how it changes animals’ traits is a question of central importance bridging evolutionary ecology and conservation management….
