Male bats with high testosterone levels have large forearm crusts when females are fertile
Diciembre 17, 2020
Male Fringe-Lipped bats smear a sticky, odorous substance on their forearms. When this was discovered, researchers guessed that it might play a role in mating. Post-doctoral fellow Mariana Muñoz-Romo has confirmed that the presence and size of the forearm "crust" is, indeed correlated with other reproductive traits.

Mary Jane West Eberhard receives Linnean Medal for Zoology
Junio 09, 2021
“Her unification of developmental plasticity and genetics is a huge advance in our understanding of evolution. Her decades-long work with tropical social wasps focusing on careful field observation is testimony to what a careful observer of natural history can contribute to evolutionary biology.”-the Linnean Society

The fate and function of marine megafauna
Junio 11, 2021
Large marine animals generally have unique functions for the ecosystem. They are also more susceptible to extinction when their habitats are altered. Around 3 million years ago, at least one third of the marine megafauna became extinct, possibly due to sea level fluctuations and the contraction of coastal habitats. This also led to a loss of some of their ecological functions. In the current era, many large marine animals are deemed at risk of extinction. What will be the consequences of this potential loss?
