Seal genomics at the Gordon Conference

By | Presentation, Research

Kristina presented her findings on the impacts of historical bottleneck, recent recovery, and geographic expansion in gray and harbor seals* at the Gordon Research Conference (GRC) on Ecological and Evolutionary Genomics in Biddeford, Maine.  GRC’s are scientific meetings with an explicit focus on cutting-edge research and promoting scientific discussion.  This year’s meeting spanned the spectrum from model to non-model system, and from theoretical to empirical.  It left me feeling inspired and excited to apply new sequencing technologies and analytical pipelines to marine mammal species in an effort to better understand their ecology and evolution.

New publication: Cost of tolerance

By | Publication, Research

In collaboration with new marine physiology professor, Nishad Jayasundara, and collaborators at Duke University, we’ve published our findings on the cost of evolving tolerance to anthropogenic pollutants in the Atlantic killifish.  These fish represent a “natural experiment” in which to study the evolution of toxin resistance; they have evolved the ability to survive exposure to high levels of PAHs, making it possible to inhabit Superfund sites in the Elizabeth River, Virginia.  In this system, our new paper explores the hypothesis that the evolution of resistance to one stressor makes organisms more susceptible to other stressors.  For more information, check out our paper here.
