ABSTRACT The global proliferation of dams has altered flow and sediment regimes in rivers, presenting a major threat to freshwater biodiversity. Diadromous species, such as fishes, decapod crustaceans and gastropods, are particularly susceptible to fragmentation because dams obstruct their breeding migrations between coastal waters and rivers. Although

The evolution of reproduction in Ediacaran–Cambrian metazoans
ABSTRACT The evolution of reproductive style is a fundamental aspect of metazoan life history but has not been explored holistically through the Ediacaran–Cambrian rise of metazoans. Recent molecular clock analyses based on only unequivocal metazoan fossil calibrations suggest that Porifera were present by at least 590 million years ago (Ma), all major

Effects of land cover and protected areas on flying insect diversity
Abstract Widespread insect losses are a critical global problem. Mitigating this problem requires identifying the principal drivers across different taxa and determining which insects are covered by protected areas. However, doing so is hindered by missing information on most species owing to extremely high insect diversity and difficulties in ...

We found microplastic contamination of the upper water column around the Chagos Archipelago, a remote, protected archipelago in the central Indian Ocean. Key aggregation areas for reef manta rays (Mobula alfredi) were contaminated, putting them at risk of microplastic ingestion.
