Exploring regenerative abilities in planarian flatworms across a diverse living collection reveals independent gains and losses of head regeneration and the rescue of regeneration defects by inhibiting a single cell–cell interaction signal.
A catastrophic flooding event offered an unusual chance to demonstrate that spatial sorting — the differential dispersal of phenotypes — occurs in soapberry bugs as they recolonize after a major disturbance. But this process does not always prove to be adaptive.
Inspired by systems biology, a statistical model now shows that low-order ecological interactions — which are inferable from relatively limited species-presence datasets — can successfully predict functional performance across synthetic microcosms.
An experiment that simulates rainfall events in dry soils reveals that virus members of the soil microbiome maintain the turnover of prokaryotic host communities through a ‘cull-the-winner’ model.
Camera-trap data from across 20 North American cities show how urbanization affects multiple mammal species, and that these effects are stronger in warmer and less-vegetated cities.
An analysis of distributions of over 99% of the world’s seed plant flora shows that species that originate from large and biodiverse regions are more successful at establishing naturalized populations outside of their native range. They are also more likely to be used by humans for economic purposes.
Genome sequences of all living kākāpō provide new approaches for evidence-based conservation management, including the identification of genomic regions that are associated with fitness traits, at a time of increased need for breeding programmes for species recovery.
An analysis of the geographical range and climatic niche dynamics of Australian frogs highlights the role of an emerging chytrid fungal disease in reshaping the distributions of native species through novel host–pathogen interactions.
A study of over 18,000 effect sizes from more than 350 published studies in ecology finds clear evidence of selective reporting and exaggeration of effect sizes.
An ancient genomics study of Holocene human individuals in Brazil provides hard-won data that illuminate the early history of population settlement in South America
International trade poses a risk to many species, especially those threatened with extinction. A new assessment tool based on the IUCN Red List may help to improve transparency, oversight and regulation of the international trade in wildlife.
Sex differences in physiology and longevity are widely observed. A study that manipulates heterochromatin content in Drosophila Y chromosomes shows no association between the length of the Y chromosome and longevity, thus challenging the hypothesis that Y chromosome-derived heterochromatin causes Y chromosome-bearing animals to live shorter lives.
An analysis of Y chromosomes from 29 primate species shows lineage-specific evolutionary strata as well as changes in the 3D structure, rearrangements and positive selection that have shaped the primate Y chromosome over the past 80 million years.
A study from Belize demonstrates how to set targets for coastal ecosystem conservation and restoration, and to quantify the resulting suite of benefits for achieving climate change mitigation and adaptation goals under the Paris Agreement.
A quasi-experimental impact evaluation quantifies reduced forest loss, avoided social cost of emissions and potential carbon-offset revenue associated with India’s designation of protected areas as tiger-conservation reserves with enhanced protection.
A new genetic study provides strong support for the view that our species evolved from exchanges between several ancestral populations in different African regions.
Human genetic material can be inadvertently captured and enriched from environmental DNA samples. This has both legal and ethical implications for future research.
Gene–environment interactions have been found to shape ageing plasticity in the muscle tissue of migratory locusts through adaptive changes in lipid metabolic processes.
