Did you know? Reindeer are the only deer species where both males and females grow antlers. Though the males shed their antlers in late autumn after mating season, the females retain theirs throughout the winter pregnancy to defend scarce food patches. It is likely then, that Rudolph was in fact a female rather than a…

Field Fiasco Friday: The Lonely Male – Bentley
It was nearly daybreak. In the twilight of the dry-forests of Costa Rica, I sat silent at the base of a giant tree along the trail. As everything around me slowly came into focus, the trees started to stir. At the top of the tree under which I sat, monkeys began to wake up…
5 Ways to be a Sensitive Animal
Animals, just like humans, can have personalities. Too bad, that unlike us, they can’t take online personality quizzes! Instead, scientists measure personality traits using behavioral assays. For example, we can test the “shyness” of an individual cricket by putting him in a box in a new space and see how long it takes him to…
Like a Moth to Flame
How humans have accidentally hacked the light-loving instincts of animals (and how animal behavior can save them). Arguably one of humans’ most conspicuous behavioral traits is our unparalleled predilection for engineering the habitats we settle upon. As we shape the world around us, some species may be drawn towards our settlements – into what they…
Buggin’ Out
It’s a hot summer night in Davis, one of the rare few where the delta breeze fails to bring relief from the scorching daytime highs. Tossing and turning in bed, you decide the effort is futile and you might as well engage in a little nocturnal foraging bout. You drag yourself from bed, bleary-eyed, and…

Bowels and Movements
It’s a classic scene: a majestic humpback whale breaches, thrusting its mass into the air. Its pectoral fins wave as it turns to land with a splash. It disappears into the depths before resurfacing, exhaling a spout of steam from its blowhole. We watch in awe, but there’s something missing in this description that may…

Getting off the ground: climbing salamanders and Individual-Based Models
By: Kira McEntire Imagine you are a salamander. You are a small amphibian found in forests, ponds and/or streams. You probably have 4 legs and a long tail. You may be brightly colored with toxic skin. Got it? Good. What are the things most important to you (as a salamander)? How do you spend…
Saving the Kingfisher!
POST BY: Andrew Alba I have been fortunate to work closely with some of the best zoos in the country. I recently completed a Master’s thesis at the University of Missouri, during which I collaborated with 21 zoos and 2 conservation breeding facilities. The commitment to animal care and welfare, wildlife conservation, and scientific research…
