Simulations of eco-evolutionary processes involved in artificial selection of microbial communities provide a guide to optimize experimental design for improving ecosystem functions.
The Y chromosome of the freshwater fish Poecilia parae may have successively evolved five haplotypes that are maintained in the population for alternative male reproductive strategies.
Four new Late Pleistocene European modern human genomes had Neanderthal ancestors in their immediate family history, suggesting that interbreeding with the last Neanderthals was common.
It has long been asserted that samples of taxa that span more of the Tree of Life contain more features that humans find useful. This has now been tested at a global scale: across 13,500 plant genera and nearly 9,500 uses, the prediction holds, supporting a macroevolutionary perspective on biodiversity conservation.
Combining detailed spatial maps of deforestation with international commodity trade patterns reveals that some countries’ consumption patterns play an outsized role in driving deforestation in others.
A collation of national spending on biodiversity presents new data and explores the relationship with biodiversity loss, while also highlighting the difficulty in generating indicators for cross-national biodiversity assessment.
Global warming is irrevocably changing coastal marine communities, resulting in community reorganizations that favour generalist fishes that are able to associate with degraded or novel habitats.
A coarse-grained model of bacterial metabolism quantitatively predicts the trade-off between drug-free growth rate and antibiotic resistance evolution.
Phylogenetic analysis of oxygen-utilizing and -producing enzymes indicates an early emergence of an oxygenated biosphere, providing phylogenetic insight into a question that has more commonly been approached from the basis of fossils and geochemical tracers.
The quantity of UVA/deep violet light varies seasonally and affects locomotor activity in a marine annelid, providing cues for phenology in addition to those provided by change in photoperiod.
Natural selection does not disappear with age, according to a new evolutionary demographic model. This conclusion is at odds with the widespread belief that ending reproduction relaxes purifying selection on alleles that increase our ageing body’s vulnerability to diseases such as cancer, Alzheimer’s or diabetes.
