A race to the bottom with a new card from the coevolutionary deck

I’m a sucker for a clever, amusing title, though I’ve recently read that amusing titles are cited less (see here). Alas, maybe a well placed metaphor can enliven a manuscript and also not get lost in a citation-less abyss? In basic … Continue reading

Pre-adapted algal ancestors colonized land

The colonization of land by plants 450 Mya marked a major transition on Earth and was one of the critical events that led to the emergence of extant terrestrial ecosystems. Chief among the challenges the terrestrial environment presented for these … Continue reading

Bees brought to their knees

As regular readers of TME will have read, this past summer was a whirlwind of sampling in which I took the briefest of holidays in the Southwest of England before attending the European Phycological Congress (read about the congress here and here). … Continue reading

Anti-predatory adaptations in sticklebacks and butterflies

Two recent studies analyze character shifts in response to different selection regimes – (1) Mullerian mimicry wing patterns in Heliconius butterflies, and (2) anti-intraguild-predator adaptations in armor and shape of threespine sticklebacks. Hoyal Cuthill and Charleston 2015 Wing patterning genes … Continue reading

On background selection in Ficedula flycatchers

Several recent studies (including those I wrote about last week) use genome-wide scans of differentiation to understand evolutionary mechanisms behind high or low divergence. However, there has been contentious support for and against these differentiation islands being due to differential … Continue reading

Sweptaway – Part 3 – Adaptation genomics of White Sands Lizards

Recent colonization events offer juicy insights into the adaptive evolution of species in response to natural selection of novel habitats – however, they are confounded by demographic changes (eg. bottlenecks, differential migration). In a recent study, Laurent et al. (2015) … Continue reading

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 …
