Research Focus:


The overarching focus of the Blois Paleoecology Lab is investigating the relationship between species, communities, and the environment, focusing on the past 21 thousand years of life on earth in order to inform the next one hundred years and beyond. We are particularly interested in determining the the ecological and evolutionary processes that underlie spatial patterns of diversity across the landscape, and how stable the relative influence of those processes have been through time.

We have many different research projects in the lab, but have been focusing particular attention to understanding drivers of variability vs. cohesion in genetic, population, and community responses to climate change, focusing on small mammals from the Sierra Nevada mountains of California.

Jessica has been involved in determining stability through time of the patterns and processes of significant species associations.

From Blois et al. 2014, Ecography. Patterns of attribution of the causes of a significant taxon pair through time, for (A) 161 segregated and (B) 288 aggregated pairs (Table 1). If there is no color for a given time period (e.g. whitespace), the taxon pair was classified as a random pair at that time or the cause could not be statistically attributed to any potential outcome. Colors are the same as in Fig. 3. See Supplementary material Appendix 1, Table A3 to match the index values with a taxon pair.
