Sometimes selection gives you more bang for your buck

Most species experience many environmental stressors simultaneously which means the direction and magnitude of evolutionary responses will depend on trade-offs between traits whose relationship may prevent them from being simultaneously optimized. Multiple sources of stress may act in opposing ways, for … Continue reading

Bigger on the inside

Evolutionary biology is, fundamentally, the study of how populations of living things change over time. Different creatures live different lives, and at any given point in time they seem to do so relatively well, which poses a question: how do … Continue reading

Coral conservation through assisted evolution

Coral reefs occupy a tiny portion of the world’s oceans (see map below) but their biodiversity is hugely disproportionate to their size. More than 450 million people from 109 countries live in close proximity to coral reefs and depend upon the … Continue reading

Interspecific gene flow enhances vectorial capacity

There are charismatic cases of gene flow between species, such as Neanderthals (see also Arun’s posts here and here), but the role of introgression in evolution remains poorly documented. Recently diverged species have incomplete reproductive isolation and can hybridize. Rapid … Continue reading

Twice Mixed? Testing hypotheses of Neanderthal Introgression

Human migration in, and out of Africa was wrought with complex patterns of admixture (see my previous post summarizing the story so far). Of note were some recent findings on the disparity in amounts of Neanderthal introgression/ancestry between East Asians … Continue reading

Rescue me

Whiteley et al. (2015) review genetic rescue (GR), or the increase in population fitness (growth) owing to immigration of new alleles, in a new paper in TREE. Genetic rescue is a controversial and hasn’t been applied to any great extent … 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

Species and sensibility

Pante et al. (2014) performed a literature review of marine population connectivity in order to illustrate the biased estimates of connectivity which can result from the failure to recognize an evolutionary-relevant unit, such as a species. When exploring the connectivity … Continue reading

Not everyone likes it hot … winter or not

On this Boxing Day, many of us may be bracing against winter storms.  For those of us in the Northern Hemisphere, we might all be dreaming of summer weather (including those of us who think a Southern Californian version of winter downright … Continue reading

C.L. Gloger’s favorite owl

Biologists love clines. We’ve been mentally masticating on clines for decades. Clines in body size. Clines in color. Clines in heart size! Clines that go in circles! Recognizing clinal patterns in phenotypes or genotypes is fun, but discovering the mechanisms behind … Continue reading
