Long-term bird population trends at the Jasper Ridge Biological Preserve by Julien Ueda, Dirzo Lab, Stanford University

Birds provide numerous ecosystem services and intrinsic value as a part of our planet’s biodiversity. However, human impacts, such as land use and climate change, have altered and depleted native bird communities. Researchers and volunteers have collected multiple long-term bird survey datasets at the Jasper Ridge Biological Preserve, and in this talk, I will present my analysis of 30 years of bird transect data. I will describe bird species population trends at Jasper Ridge, compare my results to species trends nationally, and discuss probable ecological causes. Finally, I will preview a new study I plan to conduct over the upcoming spring and summer to determine the effects urbanization has had on local bird communities.

Control and Biocides - Mosquitoes and People at Jasper Ridge by Tanvi Dutta Gupta, Hadly Lab, Stanford University

What do Silent Spring by Rachel Carson, the invention of birth control, Paul Ehrlich's research, and the Insect Apocalypse have to do with each other? All come together in the past, present, and future of mosquito control at Jasper Ridge. My presentation will tell the story of how, for the last half-century around Jasper Ridge Biological Preserve, managers, researchers, and citizens have worked to understand what it means to live with the difficult, dangerous, and sometimes just annoying parts of nature exemplified by mosquitoes.
