eDNA metabarcoding evaluated for fish diversity assessment

Environmental DNA (eDNA) metabarcoding has emerged as a powerful tool for monitoring aquatic biodiversity, enabling researchers to identify fish species from traces of DNA found in water without using invasive techniques ...

How animals use leveling behaviors to put alphas in their place

Inequality is not unique to human groups and societies. Individuals with relatively little power possess a variety of behavioral strategies to counterbalance or regulate power differences. In humans, these strategies include ...

Koala population crash came before humans, genomic study reveals

A genomic study has reshaped our understanding of the evolutionary history of the koala (Phascolarctos cinereus), revealing the iconic Australian marsupial experienced a severe population decline around 100,000 years ago, ...

How wax moth larvae can help reduce animal testing in research

Researchers at the Helmholtz Institute for One Health (HIOH) have demonstrated that larvae of the greater wax moth, Galleria mellonella, are suitable as an alternative infection model for investigating the pathogenicity of ...

Medieval pandemic left a hidden legacy in Europe's oldest trees

A new study published in the Proceedings of the National Academy of Sciences demonstrates how radiocarbon dating can reveal the maximum lifespan of Mediterranean hardwoods, uncovering hidden links between human history and ...

Scientists map more than 200 years of nature's progress

Armed with trail cameras, artificial intelligence, and a powerful national research network, scientists are revisiting Lewis and Clark's legendary journey to see how America's wildlife has changed over the past 200 years.
