There are many and increasing threats to biodiversity. To protect the plants and animals that share our world, we need to understand what they need to survive – and ideally, thrive – in a warming, more crowded world. And we need to better understand how meeting those needs can align with other societal values.

To do that, our scientists conduct ecological research to elucidate conservation problems, test hypotheses and solutions, and monitor results. We collaborate with the scientific community to inform and review our work, and share our findings with scientists and conservation practitioners around the world.

Variation in a sparrow’s reproductive success with rainfall: food and predator-mediated processes

Scott A. Morrison, Douglas T. Bolger

Reproductive success of many species in arid environments can be sensitive to rainfall patterns: rainfall events can produce a boom of primary productivity that fuels an ecological response from the…

Lack of an urban edge effect on reproduction in a fragmentation-sensitive sparrow

Scott A. Morrison, Douglas T. Bolger

Fragmentation-sensitive species – those that tend to disappear when their habitat is fragmented – pose particular challenges for conservation, in part because fragmentation ushers in such…

Arthropods in urban habitat fragments in southern California: area, age and edge effects

Douglas T. Bolger, Andrew V. Suarez, Kevin R. Crooks, Scott A. Morrison, Ted J. Case

Habitat fragmentation ushers in a wide array of ecological changes, and understanding the drivers and impacts of those changes is critical for conservation management. This study examines an often…
