Our new paper on landscape epigenetics in anoles is out in Molecular Ecology. Based on 8,459 single nucleotide polymorphisms (SNPs) and 8,580 single methylation variants (SMVs) from eight populations of the Puerto Rican crested anole, Anolis cristatellus, we compared patterns of genetic and epigenetic variation and found evidence for significant epigenetic isolation by environment (IBE), even after controlling for genetic structure. We also detected significant associations between key environmental variables and 96 SMVs, including 42 located in promoter regions or gene bodies.

Ian authored a new R package for calculating shortest topographic distances and topographic least cost paths. The topoDistance package is available from CRAN, and the paper describing the package has been published in Methods in Ecology and Evolution.
In collaboration with André Lourenço, João Gonçalves, Filipe Carvalho, and Guillermo Velo‐Antón, Ian has a new paper in Molecular Ecology comparing the effects of reproductive mode on genetic connectivity in fire salamanders (Salamandra salamandra).
