  • Predicting ecological niche space and ecosystem function from morphological traits is challenging. Here, the authors show that avian trophic diversity can be reduced to four dimensions, based on nine key morphological traits, which reflects convergence of trait combinations.

  • Diversification does not vary consistently across elevations, but highland species are more likely to migrate than lowland species, setting up species pumps that are particularly strong in the tropics.

  • The authors show how a resistance index based on biotic assemblage resemblance can predict the spread of invasive bird species without having to estimate their ecological niche.

  • Using geographical data for approximately 36,000 marine and terrestrial species and climate projections to 2100, the authors show that the area of each species’ geographical range at risk of thermal exposure will expand abruptly, highlighting the urgency of mitigation and adaptation actions.

  • Combining phylogenetic, morphological and environmental data on range overlap among 1,115 pairs of bird species, the authors show that coexistence is best explained by a model integrating both dispersal-assembly and niche-assembly processes.

  • Using annual projections of temperature and precipitation to estimate when species will be exposed to potentially harmful climate conditions reveals that disruption of ecological assemblages as a result of climate change will be abrupt and could start as early as the current decade.

  • Climate change is exposing marine species to unsuitable temperatures while also creating new thermal opportunities of varying persistence. Here, the authors examine how the interplay between these processes varies over time, demonstrating the potential of thermal opportunities to drive marine biodiversity changes, especially in the near and mid-term.

  • The authors develop a climate risk index for marine species under two emission scenarios and find that exploited species in low-income countries have the greatest risk under the high emissions scenario. Mitigating emissions reduces risks, enhances ecosystem stability and benefits low-income countries that depend on fisheries.
