Great Britain has three native shrews, while the greater white-toothed shrew (GWT: Crocidura russula ) is native to the European continent and some Channel islands. The GWT shrew was first reported in northern England in 2022. We detail its immediate investigation through national authorities, non-government bodies and individuals. Sixteen GWT were among 595 small mammals live-trapped. Barn owl pellet analysis revealed 56 GWT...

Phytoplankton play a central role in the regulation of global carbon and nutrient cycles, forming the basis of the marine food webs. A group of biogeochemically important phytoplankton, the coccolithophores, produce calcium carbonate scales that have been hypothesized to deter or reduce grazing by microzooplankton. Here, a meta-analysis of mesocosm-based experiments demonstrates that calcification of the cosmopolitan coccolith...

How do populations of highly mobile species inhabiting open environments become reproductively isolated and evolve into new species? We test the hypothesis that elevated ocean‐surface temperatures can facilitate allopatry among pelagic populations and thus promote speciation. Oceanographic modelling has shown that increasing surface temperatures cause localization and reduction of upwelling, leading to fragmentation of feeding...
