An Integrated Approach to Understanding Behavioral Responses of Free-Living Mammals to Human-Induced Rapid Change
Dr. Jennifer E. Smith and her students received a grant from Save Mount Diablo's Mary Bowerman Science and Research Program in 2018. The grant, "An integrated approach to understanding behavioral responses of free-living mammals to human-induced rapid change," supported research addressing an an important issue in ecology, the ability for wildlife to cope with human-induced rapid environmental change. A team of five undergraduates quantified variation in behavioral responses of a [...]
Ryan Fay and Ray Sullivan received a Mary Bowerman Science and Research Program grant in 2018. Ryan Fay,Â Geologist at Albion Partners, presented their research on Marsh Creek volcanics at Save Mount Diablo's Mary Bowerman Science and Research Colloquium in December 2018. This research was an investigation about the intrusive history of volcanic units in the Marsh Creek and northern Diablo area. The purpose was to explain volcanic presence including time [...]
Predatory Behavior and Cyanide Resistance of Millipede-Hunting Beetles (Promecognathus) in the Diablo Range
Brandt Weary, Entomologist, received a 2018 grant from Save Mount Diablo's Mary Bowerman Science and Research Program and presented his research at Save Mount Diablo's 5th Annual Mary Bowerman Science &Â Research Colloquium in December 2018. Weary summarized his results as follows: Promecognathus ground beetles from the Diablo range specialize on hunting millipedes that are chemically defended with cyanide. These beetles utilize a unique hunting behavior to subdue their toxic [...]
On Tuesday, December 4, Save Mount Diablo's 5th Annual Mary Bowerman Science and Research Colloquium was held at the David Brower Center in Berkeley, CA. (The Center's name honors the work of an extraordinary conservationist who was the first Executive Director of the Sierra Club and also did many other things on behalf of our environment.) The event was a huge success, full of captivating new information and discoveries presented [...]
This yearâ€™s Bioblitz was the most highly attended SMD Bioblitz since 2007, with seventy-five biologists and expert naturalists compared to the usual thirty to forty naturalists of years past. Participants came from LSA, Nomad Ecology, Swaim Biological, UC Davis, UC Berkeley, the California Academy of Sciences, and the California Native Plant Society, among others, and donated their time over the weekend. Arroyo Del Cerro is home to the federally listed California red-legged frog and â€śhas the potential for California tiger salamander,â€ť said Malcolm Sproul. Other species were spotted as well, including the endemic Contra Costa manzanita. (Endemic means this species of manzanita only occurs in the area.) In total, 419 species were found, a high number that reflects the diverse habitat on the land.
