Method‐dependent differences in zooplankton abundance and size metrics: Microscopy vs. ZooScan
Limnology and Oceanography: Methods, EarlyView.Abstract Image‐based approaches such as ZooScan are increasingly used for high‐throughput zooplankton monitoring. However, quantitative evaluations of methodological differences relative to conventional microscopy remain limited. In this study, zooplankton abundance and size‐based metrics obtained from microscopy and ZooScan image analysis were ...

Remote Sensing in Ecology and Conservation, EarlyView.Discovery and fine‐scale mapping of a hadal xenophyophore field: submersible video transects and photogrammetry enable semi‐automated delineation of xenophyophores, revealing their abundance, spatial organisation, structural complexity and contribution to habitat heterogeneity at ~8000 m depth.

Acta Zoologica, EarlyView.ABSTRACT Pedicellariae are small appendages on the surface of the echinoid test, involved in defence, cleaning, and locomotion. Pedicellariae in three species of camarodont sea urchins common in UK waters (Paracentrotus lividus [Lamarck, 1816], Psammechinus miliaris [P.L.S Müller, 1771] and Echinus esculentus [Linnaeus, 1758]) are the focus of this ...

Effects of climate change on marine biodiversity on the western Atlantic coast
Conservation Biology, EarlyView.Abstract The current climate crisis, driven by greenhouse gas emissions, threatens global biodiversity, including that in marine ecosystems. However, projections for the western Atlantic Ocean that jointly quantify species richness and endemism while accounting for spatially biased and incomplete occurrence data remain limited.

Ecology and Evolution, Volume 16, Issue 10, October 2026.Deep reefs (25–30 m) were expected to be climate havens for fish fleeing warming shallow waters near Egypt's Nile Delta—but the opposite was observed. As you head south, the reef habitat shifts from primary producers (algae) to filter‐feeding bryozoans, and fish abundance and diversity drop sharply.

Limited capacity for rapid acclimation to marine heatwaves in coastal invertebrates
Journal of Animal Ecology, Volume 95, Issue 10, Page 2088-2103, October 2026.Across 10 coastal invertebrate species, we provide a rare multi‐species test of rapid acclimation to realistic marine heatwaves. Responses are consistently weak, revealing that short‐term plasticity cannot keep pace with warming and may lead to underestimated vulnerability in coastal ecosystems. Abstract Marine heatwaves are increasing in frequency and
