My name is Margie Mayfield and I am a postdoctoral fellow at UCSB working with Jonathan Levine. My research focuses on how human activities influence the diversity, ecology and evolution of native plant communities. For my postdoc, I am studying variation in the germination biology of 40 native annual plants living across the current climate gradient found in coastal California. The goal of this work is to make better predictions about how annual plant species will respond to human-induced climate change. In addition to my postdoctoral research , I also have ongoing projects in other systems. These are my other research projects. 1. I am interested in the impacts of landscape structure on the evolution of native plant species surviving in agriculture-dominated landscapes. My work on this subject focuses on native wetland plants living in the rice fields and remnant wetlands of Northern California. 2. Based on my graduate research on the diversity of herbaceous and shrubby plants in human-dominated landscapes in Costa Rica, I continue to examine how plant communities in deforested and forested portions of tropical landscapes differ in terms of their biodiversity, functional diversity and ecological processes. 3. I also am very interested in factors influencing crop pollination by wild pollinators. In the past I have done serveral projects examining the effects of wild vegetation on crop pollination services in agricultural landscapes.
