Tubbataha Reefs Natural Park: the first comprehensive elasmobranch assessment reveals global hotspot for reef sharks

Journal of Asia-Pacific Biodiversity, 2019
Elasmobranchs are experiencing population declines worldwide because of anthropogenic stressors. Marine protected areas (MPAs) have been shown to benefit mesopredatory species of shark.

Corallivore assemblage, feeding behavior, and cover of Acropora corals drive fish corallivory on tropical reefs

Ecosphere, Volume 17, Issue 9, September 2026.
Abstract Understanding spatial patterns and drivers of corallivory is essential for assessing reef resilience and identifying recovery pathways. Fish corallivory patterns arise from the complex direct and indirect effects of key factors, including food availability (cover of preferred corals), the nature of the corallivore assemblage (richness and ...

Two eDNA Assays to Detect the Sympatric Seahorses Hippocampus hippocampus and Hippocampus guttulatus During Their Northward Range Shifts

Environmental DNA, Volume 8, Issue 5, September‐October 2026.
Small and well camouflaged fish are difficult to monitor, but they do release DNA into the water (1). These assays allow for targeted monitoring of two European seahorses of conservation concern, using two primers and probe pairs with high specificity (2) and proven detections from the field (3).

Refining techniques for high‐frequency monitoring of chlorophyll a fluorescence in estuarine systems

Limnology and Oceanography: Methods, Volume 24, Issue 9, September 2026.
Abstract Concentrations of the photosynthetic pigment chlorophyll a are commonly used as a proxy for phytoplankton biomass in aquatic systems. Traditional methods for extracting chlorophyll a in discrete samples limit measurement frequency, while in situ sensor technology provides high frequency chlorophyll a fluorescence measurements at a more ...

Deep blueprint: A literature review and guide to automated image classification for ecologists

Journal of Animal Ecology, Volume 95, Issue 9, Page 1558-1585, September 2026.
A practical, literature‐grounded review that gives ecologists a clear, modular workflow for deep learning image classification. With code, GUIs and a novel deep sea case study (automated deep sea biotope classification) it lowers technical barriers and provides a usable blueprint for accelerating, standardising, and scaling ecological image analysis ...

Native habitat affinities predict fish invasions with post‐invasion habitat shifts

Journal of Animal Ecology, Volume 95, Issue 9, Page 1762-1777, September 2026.
Initial invasion success is gated by native pre‐adaptations, but post‐invasion establishment is characterized by habitat shifts. We demonstrate that forecasting risk based solely on native niches severely underestimates future ecological impacts, and we provide an empirically validated watchlist of future invaders.
