Peer-reviewed journal covering the use of molecular methods in ecology and evolution, including population genetics, conservation genetics and eDNA.
Flinders University researchers resampled replanted sites over six years and found different parts of the soil fungal community recover at different rates. Vegetation, the usual yardstick of replanting, does not automatically show soil recovery, the Flinders researchers warn.

Smithsonian and Penn State researchers sampled more than 370 museum frogs from Boracéia, Brazil, and found chytrid fungus only in specimens from the 1980s. The timing matches the 1979 to 1982 die-offs that some scientists had blamed on climate or extreme weather.
Reality
Researchers raised wasp spiders from opposite ends of Europe under identical lab conditions to ask whether the species' northward spread involves evolution and not only warmer weather, as British sightings arrive further north.

By pulling DNA out of annually layered mud, a team rebuilt 1,000 years of plants, animals, bacteria and fungi at the lake proposed as the Anthropocene's marker, confirming decades of earlier work and adding cattle the older methods never saw.

A Leeds-led team sequenced 363 birds and 51 shared food and water resources at 12 farmland sites, and found the more virulent Type A strain over twice as prevalent in birds feeding at dense stations as at wild seed.

University of Georgia researchers report the first epigenetic age clock validated in a shark, built from 10 DNA methylation markers in blood. The alternative is killing the animal.
