The nature of the last universal common ancestor and its impact on the early Earth system
The nature of the last universal common ancestor (LUCA), its age and its impact on the Earth system have been the subject of vigorous debate across...

Co-evolutionary dynamics of mammalian brain and body size
Despite decades of comparative studies, puzzling aspects of the relationship between mammalian brain and body mass continue to defy satisfactory...

Floristic diversity and its relationships with human land use varied regionally during the Holocene
Humans have caused growing levels of ecosystem and diversity changes at a global scale in recent centuries but longer-term diversity trends and how...

Viperin immunity evolved across the tree of life through serial innovations on a conserved scaffold
Evolutionary arms races between cells and viruses drive the rapid diversification of antiviral genes in diverse life forms. Recent discoveries have...

Global evaluation of current and future threats to drylands and their vertebrate biodiversity
Drylands are often overlooked in broad conservation frameworks and development priorities and face increasing threats from human activities. Here we...

Insufficient pollinator visitation often limits yield in crop systems worldwide
Declining pollinator populations could threaten global food production, especially if current crop yields are limited by insufficient pollinator...

Metabolic complexity drives divergence in microbial communities
Microbial communities are shaped by environmental metabolites, but the principles that govern whether different communities will converge or diverge...

Extant and extinct bilby genomes combined with Indigenous knowledge improve conservation of a unique Australian marsupial
Ninu (greater bilby, Macrotis lagotis ) are desert-dwelling, culturally and ecologically important marsupials. In collaboration with Indigenous...

Tree phytochemical diversity and herbivory are higher in the tropics
A long-standing but poorly tested hypothesis in plant ecology and evolution is that biotic interactions play a more important role in producing and...

Habitat amount modulates biodiversity responses to fragmentation
Anthropogenic habitat destruction leads to habitat loss and fragmentation, both of which interact to determine how biodiversity changes at the...

Spatial match–mismatch between predators and prey under climate change
Climate change is driving a rapid redistribution of life on Earth. Variability in the rates, magnitudes and directions of species’ shifts can alter...

Increasing frequency and intensity of the most extreme wildfires on Earth
Climate change is exacerbating wildfire conditions, but evidence is lacking for global trends in extreme fire activity itself. Here we identify...
