Lab Meeting 28 March: Sticklebacks and the genetics of adaptation

Posted on Posted in Uncategorized

We’re going to switch topics to sticklebacks for the next 3 weeks, and there’s plenty to talk about. I’d like to begin with consideration of research exploring the genetic architecture of ecomorph traits in sticklebacks, and how these studies contribute to resolving outstanding, largely theoretical debates about the the nature of adaptive evolution. So we’ll […]

Adaptive Radiation of Sulawesi Fanged-frogs

Posted on Posted in Field Work, Research Updates

Sulawesi is a remarkable island for the study of speciation. The island has always enjoyed isolation from other land areas, but until fairly recently (in geologic history) the island was actually an archipelago, so it is possible to assess what happens when closely related, allopatrically distributed species come into secondary contact in the regions where […]

Lab Meeting, Friday 9 September, 12:00pm

Posted on Posted in Lab Meetings

We’re going to discuss two papers that are a prelude to a manuscript I am finishing. One is a discussion of Madagascar as model region for the study of species diversification, and discusses several mechanisms that may be responsible for the major patterns of diversity on the island (i.e., species richness and micro-endemicity). The next […]

Recent Papers on the Neutral Theory (the Biodiversity One)…

Posted on 15 CommentsPosted in Fun Stuff, Research Updates

Just stumbled upon some recent papers concerning the neutral theory of biodiversity and biogeography that I thought I’d share.  The first is an examination of the effects of neutral processes on phylogenetic tree imbalance (Davies et al. 2011). Interestingly, the authors find that neutral theory can account for the variation in species diversity among clades […]

We’ll continue in the community structure vein with a recent selection from Ecography: Machac et al. 2011. If there’s rain, we’ll stay behind and watch a heavily medicated Prof. Glor speak slur in tongues.  Otherwise, I’m feeling Sully’s or Lee’s Vietnamese Sandwiches.

Lab Meeting 5 April 2011

Posted on Posted in Uncategorized

I’m going to discuss some results from a recent project I started, so lets read these two papers: Vast underestimation of Madagascar’s biodiversity evidenced by an integrative amphibian inventory and Density-dependent diversification in North American wood warblers. I’ll begin with a discussion of the Malagasy herpetofuana, with an emphasis on frogs and geckos, including the […]

Gonatodes and Neil Diamond: the future of evolutionary biology?

Posted on 1 CommentPosted in Research Updates

Friend, collaborator, and fellow geckophile Tony Gamble just published an exciting paper in the Journal of Evolutionary Biology elucidating the biogeographic history of all New World gecko lineages.  A particularly noteworthy finding is that geckos reached the Americas via almost every possible biogeographic scenario: land bridges, overseas dispersal, and human-mediated introductions [DOI link].  If that’s […]
