What we’re reading: Landscape genetics of pikas, a genetic link between larval and adult behavior, and the saddest quest story of the year so far

Castillo JA, CW Epps, AR Davis, SA Cushman. 2014. Landscape effects on gene flow for a climate-sensitive montane species, the American pika. Molecular Ecology doi: 10.1111/mec.12650.

Pikas are heat intolerant and restricted to cool microclimates, thus range contractions have been predicted as climate changes. We evaluated the correlation between landscape variables and genetic distance using partial Mantel tests in a causal modeling framework, and used spatially-explicit simulations to evaluate methods of model optimization including a novel approach based on relative support and reciprocal causal modeling.

Edelsparre AH, A Vesterberg, JH Lim, M Anwari, MJ Fitzpatrick. 2014. Alleles underlying larval foraging behaviour influence adult dispersal in nature. Ecology Letters doi:10.1111/ele.12234.

Using laboratory and field experiments, we demonstrate that natural allelic variation in a gene underlying a foraging polymorphism in larval fruit flies (for), also influences their dispersal tendencies as adults.
