Kirsten Fisher

California State University, Los Angeles

The Fisher lab is broadly interested in the ecology and evolution of mosses in extreme environments, and we currently use ecological genomics to address questions about reproductive ecology, demography, and genetic diversity in populations of the desert moss, Syntrichia caninervis.

For the Dimensions project, my students and I will be investigating areas such as:

  1. population sex ratios and their correlation with (macro)environmental variables
  2. microhabitat niche partitioning between male and female mosses within populations
  3. the extent of population differentiation along environmental versus geographic gradients
  4. the frequency and direction of migration between populations
  5. and the influence of mosses on hypolithic microbial community composition.
