(Un)usual sources of ancient DNA
Working with ancient DNA can be quite painful at times, but hard work pays off (or so they say) and scientists are starting to reap great benefits from their effort by exploring more and more things to extract DNA from.

The Hype Cycle of Ancient DNA
Recently I saw a graph that I’ve learnt is called the Hype Cycle and is a methodology used in assessment of new technologies and their marketing. What strikes me about it is how well it fits my own research field, … Continue reading

Mapping genomes and navigating behavior for wildlife conservation
Virginia Aida wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. She is currently evaluating a potential pharmacotherapy in traumatic brain injury and anticipates graduating with her MS in summer 2017. Although she … Continue reading

Like Turtles, Terrapin Research Moves a Little Slow
Marlee Hayes wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. Her primary interests focus on challenges in conservation and sustainability. Previously, she evaluated fitness of post-hatchling Diamondback terrapins (Malaclemys terrapin), … Continue reading
Different ways to have sex, yet still be a weed
Baker (1955) noticed that when mates are lacking, the ability to undergo self-fertilization will greatly enhance colonization success. Uniparental reproduction seems to be common in colonizing species, whether it’s from a continent to an oceanic island, during a biological invasion or during range … Continue reading
Polyploidy in the era of GBS
Ploidy, dear reader, is something that I think about literally all the time. It impacts every facet of my research from the field to the bench to the stats used to analyze data sets. It’s been simultaneously the greatest and the … Continue reading

Deep in the meadow, under the … seagrass, a bed of temporally stable diversity?
Genetically diverse populations are often more stable and productive. For habitat-forming organisms, such as seagrasses, this results in increased habitat complexity and more abundant associated communities (e.g., Hughes and Stachowicz 2004, Reusch et al. 2005). Spatial patterns of genetic diversity … Continue reading
