How do you use genome-wide diversity in conservation?
Measuring how genome-wide diversity matters to threatened species has been a constant endeavor of conservation genetics, and still is in the era of genomics. But what should we do with the fact that it often do not correlate with IUCN Red List categories, a measure of species’ threat status? Continue reading
In the pipeline – Part 1: ‘Plan, plan, and plan some more’
So you’ve decided it’s time to finally get around to starting that sequencing project. But before you aimlessly leap into it and generate terabytes of sequencing data, just STOP. It’s far too tempting to rush into sequencing projects for a … Continue reading

Fieldwork in the time of COVID
Life as we knew it came to a screeching halt back in March. Almost a year ago, how is that possible??? Yet, at the same time it feels like several lifetimes have passed … At a recent editorial meeting, we … Continue reading

Kelp forests: the underwater woodlands
Aisha O’ Connor wrote this post as a project for Stacy Krueger-Hadfield’s Conservation Genetics course at the University of Alabama at Birmingham. She sat in on lectures while she was at UAB as part of a British Phycological Society Student Bursary … Continue reading
La vie en rouge … l'algue rouge
Best laid plans of a #NewPI … what happens to them? Well, they often get triaged for more urgent things that were triaged earlier for more urgent things that were also triaged even earlier for more urgent things … and … Continue reading
When less might be more: The evolution of reduced genomes
The advent of affordable genome sequencing has provided us with a wealth of data. Researchers have sequenced everything from Escherichia coli (4.6 Mbp genome size), to sea urchins (810 Mbp), chimpanzees (3.3 Gbp), and humans (3.2 Gbp). Then there are the … 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
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
Have we got the power?
Sabrina Heiser wrote this post as a final project for Stacy Krueger-Hadfield’s Science Communication course at the University of Alabama at Birmingham. Sabrina grew up in Germany, completed a BSc (Hons) in Marine Biology at Plymouth University (UK) and then lived … Continue reading
Divergence and Linked Background Selection
We have widely discussed the reduction in neutral diversity due to demography and linked selection effects (e.g. selective sweeps and hitchhiking, or background selection) in several previous posts (e.g see here, here, and here). However, how linked selection affects neutral divergence … Continue reading
