Habitat-matching dispersal facilitates local adaptation

Migration disrupts local adaptation. At least, this is the first reaction I have when I consider these two processes. In fact, my initial thought is almost always: how strong does selection have to be to overcome gene flow? Gene flow … Continue reading

Shared patterns of genomic diversity across populations of distantly related taxa

Genomic diversity is shaped by the complex interplay between the effects of genetic drift and natural selection among populations. Several of these effects, especially those of linked selection at neutral sites, adaptive introgression, and barriers to migration (often called “genomic … Continue reading

Music to an amniote’s ears, an “accordion” model of genome size evolution

How did we get where we are? Genetically speaking, that is. A few posts ago, that whole genotype-phenotype question was discussed, how do genomes make plants and animals (and don’t forget the microbes!) look and act how they do. Another … Continue reading

At the molecular level, there’s more than one way to fly higher

Parallel adaptation is coming into its own lately, as we’re increasingly able to examine the molecular changes underlying similar adaptations in distantly related species. A fundamental prediction of evolutionary theory is that species coping with the same environment should converge … Continue reading

Conifer convergence

Convergent local adaptation is typically studied within a species or between closely related species. In these cases, it is perhaps not unexpected to observe parallel evolution due to common genetic variation, constraints, etc. Convergence between species is somewhat less studied, … Continue reading

Macroalgal miscellany

It’s been a jam-packed week and I’ve found myself at Friday. Grandiose plans for a post continuing the series on clonality (see here and here) did not come to fruition. But, I was saved with a new article that tumbled … Continue reading

What we’re reading

As we head into the weekend, here’s a few things we found this week that might be worth your screen time: In the journals Maughan, H., P. W. Wang, J. Diaz Caballero, P. Fung, Y. Gong, S. L. Donaldson, L. … Continue reading
