Selection scans, and the genomics of adaptive/maladaptive introgression
Natural selection, and the adaptive evolution of hybrid reproductive incompatibilities post divergence are known to be major drivers of speciation. At the phenotype level, these manifest as fitness differences between introgressing populations. At the genomic level, speciation “genes” or “islands” … Continue reading
Sous les mers: cradles or museums of biodiversity?
While thinking about environmental genomics and writing this post on a recent article in Heredity, I interviewed Eric Pante.

Grasping gorgonians
A recent issue of Heredity focused on the brave new world of environmental genomics. After highlighting the special issue, I started chatting to one of the contributors, Eric Pante and became interested in his work on gorgonians. Eric and his co-authors explored the … Continue reading

Clonal conundrum, part un
Molecular ecologists are faced with a clonal conundrum when we wish to investigate the evolutionary ecology of clonal organisms. An attack of the clones is not something that should frighten one away …
Just like an elephant and a manatee …
There is a positive correlation between the time since two lineages have diverged and the strength of the reproductive barriers between them. Rothfels et al. (2015) have described a natural hybridization event between two fern genera that diverged from one … Continue reading

Beauty is in the eyes of the beholder
Many animals use visual signals to scope out potential mates. In a new paper in Molecular Ecology, Sandkam et al. (2015) demonstrate that the variation underlying preference in female guppies could be explained by simple changes in expression and coding of … Continue reading
From crocodiles to coconuts
The first plant trypanosomatids were discovered in plant tissues over 100 years ago, but we know very little about their biology, life cycle or how they have adapted to life inside plants. Jaskowska et al. (2015) provide a review of … Continue reading

Growing the evolutionary relationship between green algae and salamanders
The presence of green algae within the developing egg masses of amphibians has been recognized since the early 1900s, but only recently have researchers discovered that the these algae (termed “Oophila”) persist in animal tissues far after leaving the egg. The … Continue reading
