Tropical Atlantic nitrogen isotope records show that N₂ fixation was reduced during the warm late Pliocene due to decreased global water column denitrification. It increased as Earth cooled into the P...

Late Ordovician ostracods from the “butter shale” Lagerstätten of the Cincinnati Arch region, Ohio, USA

The relative importance of biotic and abiotic factors in clade extinction is unclear. Here the authors identify 2 extinction phases in 12 extinct marine clades, an initial, gradual decline reflecting ...

Climate change impacts not only life on land but also the largely unexplored deep-sea ecosystem, home to unique and largely unexplored fauna. Deep-sea animals, which have adapted to stable and extreme...

Wan et al. reveal that rice-fish coculture enhances invertebrate natural enemies (i.e., predators and parasitoids), suppresses pests (i.e., invertebrate herbivores, diseases, and weeds), and boosts ri...

In the Ukrainian part of the Danube Delta, rewilding efforts have reconnected the life-giving waters of the River Danube with Lake Kartal. The lake’s rapid comeback — and the growing benefits this is ...

Western boundary observations in the Atlantic suggest a meridionally consistent decline in the ocean overturning circulation.

The Quaternary Period (the last 2.58 Ma) was characterized by the waxing and waning of large ice sheets in the Northern Hemisphere. Using sediment sequences from the Iberian Margin, we demonstrate tha...

The discovery of the live animals in New Guinea, originally known only from fossils, is a story of hope for biodiversity and the importance of conservation across the Pacific.

Nature Ecology & Evolution - The authors survey community palaeontological databases, documenting their contributions to science as well as their vulnerabilities, and provide recommendations...

New findings from articulated head and trunk material of Megamastax amblyodus yield previously unseen morphological details of a Silurian stem osteichthyan.

This preliminary study investigates the trace-element composition of ostracod shells (Ostracoda: Crustacea) as biogenic calcium carbonates in their ro…

Using nitrogen isotopes from ancient and modern fish otoliths and corals, the study shows Caribbean reef food webs are now 60–70% shorter and functionally less diverse, indicating human-driven trophic simplification and increased risk of collapse.

Abstract. Over the past century and into the present, rates of overexploitation of species globally have increased significantly (for large species and sma

Heredity - Seizure samples reveal complex evolutionary dynamics among Southeast Asian pangolins

Central to the purpose of the Academy is the recognition and support of outstanding contributions to the advancement of science. The honorific awards recognise outstanding contributions to the advance...

Climate change threatens the future of the Antarctic Ice Sheet. Here the authors show that individual drainage basins have different thresholds and loss patterns, suggesting the need to consider the d...
