Can you believe that until now there were more genomes sequenced for the woolly mammoth than for living African elephants?

Today, we bring you the first genomic, continent-scale analyses of 232 high-quality genomes of both species, the savanna and forest elephant.

Very excited to share our study of an ancient environmental genome extracted from lake sediment! It originates from a brown bear that lived around 9,600 years ago close to the last ice-sheet remains in northern Sweden, and has an unexpected mitochondrial haplogroup. 1/7 www.pnas.org/doi/10.1073/...

A single wandering male bear has provided crucial insights into the history of brown bears in Scandinavia after the last ice age. This is shown by DNA analysis of clay from a lake. New study from @cpgsthlm.bsky.social & @zoologysthlm.bsky.social published in @pnas.org

Whole genomes reveal subpopulations and isolation-by-distance patterns in the Norwegian lemming - BMC Biology Background The Norwegian lemming (Lemmus lemmus) is a small rodent endemic to the Fennoscandian alpine and arctic tundra. The species is known for cyclic population outbreaks and mass movements during peak years. Previous research based on microsatellites revealed high genetic variation but a weak population structure in the Norwegian lemming. Results In this study, we revisit the population structure of the species using genome-wide data. To do this, we generated a high-quality de novo reference genome for Lemmus lemmus, and resequenced genomes to 2.5–5 × coverage, from 86 lemmings sampled across the species’ entire geographic distribution. Our results reveal that the population is geographically structured into distinct subpopulations, with an overall pattern characterised by isolation-by-distance among subpopulations. Furthermore, our results are consistent with earlier work suggesting that the species survived the last ice age within a northern refugium. Conclusions Together, these findings provide a genome-wide perspective on today’s population structure of the Norwegian lemming. In addition, we provide a de novo reference genome, which we believe will be a valuable resource to the research community.

How did catastrophic black death and myxomatosis outbreaks on an isolated island affect the genomes of humans & rabbits, respectively?

And how did the microbes evolve in response to this?

It’s always been a mystery to me how the genetic diversity and composition of the Scandinavian brown bear originated 🤔

Today, we publish a new paper that sheds new light on this, and a real-time example of how mito-nuclear discordances can evolve during severe bottlenecks:
