Using environmental DNA for fish monitoring

Using environmental DNA for fish monitoring

Kara Andres, a Living Earth Collaborative postdoctoral researcher, used eDNA to follow invisible trails of genetic information from fish. While her original study probed the Great Lakes, her recent work is focused on microbial communities in local waterways.
Hormone alters electric fish’s signal-canceling trick

Hormone alters electric fish’s signal-canceling trick

New research from Washington University in St. Louis shows that testosterone — which naturally triggers male electric fish to broadcast slightly different signals during the breeding season — also alters a system in the fish’s brain that enables the fish to ignore its own signal. The study by biologists Matasaburo Fukutomi and Bruce Carlson in Arts & Sciences is published in Current Biology.

Schaal elected member of American Philosophical Society

Barbara A. Schaal, the Mary-Dell Chilton Distinguished Professor in the Department of Biology in Arts & Sciences, was elected a member of the American Philosophical Society in May. Schaal was among the first scientists to use molecular biology-based approaches to understand evolutionary processes in plants.

Missouri native is flowering earlier due to climate change

Biologist Matthew Austin in Arts & Sciences published a study in the American Journal of Botany that describes changes to the flowering time and other important life cycle events in Leavenworthia species, a group of small flowering plants found in glades in Missouri.
Wonder, enchantment and the epic of evolution

Wonder, enchantment and the epic of evolution

As a biology faculty member, Professor Emerita Ursula Goodenough invited non-science majors to understand and reflect on the history of life on Earth. The second edition of her book, The Sacred Depths of Nature: How Life Has Emerged and Evolved, brings the wondrous saga to a new audience.
