个人简介

Plant Ecology, Community Ecology, Vegetation dynamics (dispersal, seed banks, seedling establishment, mycorrhizae), Fire Ecology, Vegetation conservation and management, Evolution and Ecology of Arctostaphylos (Ericaceae) and Ceanothus (Rhamnaceae), Tidal Wetlands, Chaparral, Mixed Evergreen Forests I study the ecology and evolution of plant communities, focusing on their dynamics. Current research includes the effects of climate change on tidal wetlands of the San Francisco Bay-Delta, and the ecology and evolution of Arctostaphylos species in chaparral and other communities.

研究领域

Research in this lab focuses on questions related to short and long-term community dynamics. Current topics include: 1) ecology and evolution in Arctostaphylos (Ericaceae), and ecological evolutionary impacts such as the influence of seed size on the density of seeds in long-term persistent seed banks, ecological significance of leaf morphology. 2) the effect of climate change on tidal wetlands in the San Francisco Bay-Delta estuary, coastal scrub and other systems. 3) Mutualisms: These mostly include aspects of dispersal and mycorrhizae. 4) conceptual approaches to how ecological systems work
