We present an overview of the global spatiotemporal distribution of avian biodiversity,
changes in our knowledge of that biodiversity, and the extent to which it is imperilled. Birds …

Invasive species are pervasive around the world and have profound impacts on the
ecosystem they invade. Invasive species, however, can also have impacts beyond the …

The inherent complexity of high‐diversity systems can make them particularly difficult to
understand. The relatively recent introduction of functional approaches, which seek to infer …

The world's coral reefs are rapidly transforming, with decreasing coral cover and new
species configurations. These new Anthropocene reefs pose a challenge for conservation; …

Marine megafauna, the largest animals in the oceans, serve key roles in ecosystem
functioning. Yet, one-third of these animals are at risk of extinction. To better understand the …

Coral reefs are highly diverse ecosystems that thrive in nutrient-poor waters, a phenomenon
frequently referred to as the Darwin paradox. The energy demand of coral animal hosts can …

Environmental DNA (eDNA) metabarcoding, a technique for retrieving multispecies DNA
from environmental samples, can detect a diverse array of marine species from filtered …

Exotic species are a growing global ecological threat; however, their overall effects are
insufficiently understood. While some exotic species are implicated in many species …

Identifying species that are both geographically restricted and functionally distinct, ie
supporting rare traits and functions, is of prime importance given their risk of extinction and …

Positive relationships between biodiversity and ecosystem functioning (BEF) highlight the
importance of conserving biodiversity to maintain key ecosystem functions and associated …
