We used experimental evolution to test the central assumption that parasites evolve to target rare over common host genotypes. It’s out today in Biology Letters!

The lab has been awarded an R35 MIRA through the National Institute of General Medical Science! Our project “A general test of the genetic basis of parasite resistance across genetic and environmental contexts” will study the evolution of parasite resistance across genetic and environmental contexts. We plan to use experimental evolution, evolutionary theory, transgenic lines and GWAS and QTL mapping withC. elegans and its natural parasites.
The lab has received a Jeffress Trust Award in Interdisciplinary Research for our project “Modeling the Evolution of Disease Resistance in a Variable World”! This grant funds research that merges computational and quantitative scientific methodologies and supports undergraduate researchers in the lab.
Fabiane Mundim – a nematologist, ecologist, and plant physiologist – has joined the lab as a postdoctoral researcher! She comes to us from the University of Nevada, Reno, where she worked on the impact of root parasites on the stability of ant-aphid mutualisms above ground. Welcome Fabiane!
2nd-year undergraduate Sophie Wong received a grant from the Ingrassia Family Echols Scholars Research Fund to support her work using experimental evolution to select for thermal tolerance in the algal symbionts of coral. Congratulations Sophie!
Extensive musings on a problem nicely summarized White (1973, Animal Cytology and Evolution)
“It is not entirely clear…how forms whose genetic system must be very inflexible manage to become adapted to new environments when they do get transported to them: the apparent ecological versatility in space seems to be at variance with their lack of ecological versatility in time.”
Thanks to Simran for help in data collection, Ryan Earley for inviting the paper, and the Wissenschaftskolleg zu Berlin for the time to think.
The Gibson lab had a blast at the Southeastern Population Ecology and Evolutionary Genetics Conference at Clemson this weekend! Big congratulations to Emily and Anna for presenting awesome posters on their work.
The Gibson lab achieved Gold Level Certification as part of UVA’s Green Lab’s Sustainability Program!! We’re one of only four labs on campus to have achieved Gold, the highest level of the program. Thanks in particular to our Green Leader Anne Janisch for spearheading this effort!
