Proceedings of the National Academy of Sciences (PNAS), a peer reviewed journal of the National Academy of Sciences (NAS) - an authoritative source of high-impact, original research that broadly spans...

We show that species from phylogenetically diverse home ranges can colonise even undisturbed sites, highlighting evolutionary imbalance as a potentially influential driver of asymmetric invasion patt...

Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long-term dynamics of biological invasions. A large body of empirical research on bio...

Plants use chemicals to respond to consumers, competitors, and the wider environment. Most work has focused on consumers in driving the diversity of these

Darwin's theory of natural selection provides two seemingly contradictory hypotheses for explaining the success of biological invasions: (1) the pre-adaptation hypothesis posits that introduced speci....

Freshwater bivalves are globally distributed, diverse, and common in benthic communities. Many taxa, particularly in the most species-rich order, Unionida, are declining due to anthropogenic stressor...

Scale terms, which include both ecological (e.g., ‘local’, ‘regional’) and methodological (e.g., ‘plot’, ‘quadrat’) characteristics are frequently used in plant community ecology. We show that the ar...

Many specialized metabolic pathways have evolved convergently in plants, but distinguishing multiple origins from alternative evolutionary scenarios can be difficult. Here, we explore the evolution .....

Lepidoptera is the most herbivorous of all the insect orders, with predatory caterpillars globally comprising less than 0.13% of the nearly 200,000 moth and butterfly species. Here, we report a specie...

2024 HARPER PRIZE SHORTLIST: For the next two weeks, we are featuring the articles shortlisted for the 2024 Harper Prize. The Harper Prize is an annual award for the best early …

The enemy release hypothesis as an explanation for (a) increased exotic performance is the product of (b) three factors, which are modulated by (c) seven contexts. Three factors: 1) the difference in...

Parasite species frequently co-occur more or less than expected by chance. These nonrandom co-occurrence patterns can be driven by pre- or postinfection priority effects: parasites are more or less l...

Many taxa around the globe are threatened by often unexplained mass mortality events (MMEs), which can decimate populations and compromise key ecosystem functions. One example of a highly threaten...
