Jennifer R. Gremer
I am a second year PhD student in the Population Biology graduate group studying population and community ecology. I am particularly interested in invasive species, functional traits, and demographic studies.
I am a first year PhD student in the Population Biology graduate group primarily interested in investigating the effects of climate change on plant responses. Currently, I am working on a project exploring the impacts of snow melt on the phenology and population genetics of a native California wildflower, Streptanthus tortuosus, at Lassen Volcanic National Park. During my PhD, I aim to ask questions that lie at the interface of evolutionary biology, genetics, and ecology, and answer those questions using a combination of observational, genetic, and experimental techniques. Other research topics I may explore include studying the effects of climate change on plant-pollinator interactions, plant distributions, and landscape genetics and how those effects differ at varying spatial scales. I am also an avid science writer and communicator. See research updates on my blog here and my science writing portfolio here.
Visiting Graduate Student
I am a PhD candidate at the University of California, Irvine and a recent National Park Service Young Leader in Climate Change. I am a plant ecophysiologist interested in invasive species, their evolutionary ecology, and their impacts on native plant communities in “extreme” environments. My field sites include much of the desert southwest, alpine regions of Colorado, the montane forests of Baja California, and the tundra of northern Japan. All of my research focuses on climate change impacts on native systems, with an emphasis on Parks and protected areas. For more information, please check out my website.
I help out with a number of projects in the lab, but most of my time goes towards studying life history evolution in Streptanthus tortuosus. This plant is very labile in its life history strategies, and I’m particularly interested in the role this lability has played in shaping the range of S. tortuosus. At a larger scale, I’m curious about the prevalence of within-species life history lability and how evolutionary transitions in life history strategies have shaped plant diversity.
Undergraduate Research Assistant
My research interests are primarily revolving around plant ecology, focusing on the varying requirements for germination in Streptanthus tortuosus across the different environments it grows in as well as the fitness of the seeds that do germinate in the differing treatments they undergo. I hope to also look at whether the different treatments that induce germination will have any effect on the phenotypic differences in the mature plants.
