Depth & upwelling reshape annelid communities: SACW pulses spark trait overdispersion on Brazil’s inner shelf, while deep, coarse sediments keep it offshore. Timing upwelling is key for monitoring & conservation. #MEPS #Upwelling.@marinecologybot

Mangrove expansion onto intertidal oyster reefs was found to be associated with reef acidification and loss of oyster shell mass. These findings indicate mangroves can negatively impact oysters, potentially degrading reef habitats over time.

Pacific oysters thrive with the right phytoplankton. Our 10-year study shows that non-harmful diatoms, such as Skeletonema, Asterionellopsis glacialis, and Thalassiosiraceae, promote growth, unlike other diatoms or dinoflagellates.

Our Bayesian #IntegratedPopulationModel revealed key insights into Baltic #RingedSeal population dynamics, responses to sea ice loss, and interactions with human activities, offering essential guidance for monitoring and management efforts.

Drones, photogrammetric measurement techniques, photo-identification, and an individual-based multivariate model were used in this study to estimate growth dynamics of bottlenose dolphins living in the fiords of southwestern Aotearoa/New Zealand.

Identifying trophic units of the Fuegian sprat (Sprattus fuegensis), a key forage species in the SW South Atlantic, is crucial to understand its ecological role, improve management strategies, and support conservation efforts.

Atlantic bluefin tuna diet meta-analysis reveals environmental, spatial, temporal, and biological drivers.

Tracking movements of invasive green crabs with an acoustic telemetry positioning system in a Maine estuary quantifies home ranges and assess how movements vary with reproductive status and environmental conditions.

Ecosystem modelling of the Barents Sea applying hot climate scenarios resulted in a community shift towards northeast in the 2090s. In contrast, under cool and intermediate scenarios, spatial patterns became similar to the present after 2050.

Video is a common gear to survey fish in structured habitats, but it is often assumed that video detects all species present. The authors used a paired sampling approach to show that video detection for reef fish species was never perfect. @fishynate

Inshore South African Bryde’s whales show within-population foraging plasticity. Individual whales use different modes of lunge-feeding, at different depths & within the same feeding dive, revealing how whales optimize the depth & time of a foraging event.

How do corals time reproduction in equatorial reefs? A study at Lankayan Island, Malaysia, shows how seasonal light cycles synchronize coral gametogenesis. Understanding these cues helps predict coral resilience to climate change!.

New study uses passive and active acoustics with oceanographic sampling to examine how cetaceans are impacted by prey responses to the physical environment, offering insights into predator–prey dynamics and informing management strategies.

White sharks are on the rise in Atlantic Canadian waters! Our new study reveals an increase in their presence since 2019, with migration probabilities up to 3.7x higher and their seasonal stay extending by over 20 days.

We characterized neonatal growth patterns in harbour seal pups in the St. Lawrence Estuary. We found that neonatal growth is nonlinear. Males are born heavier than females and large pups at birth tend to gain more mass than small pups.

Tropical #CoralReefs host rich hidden biodiversity. Our study shows how deterministic & stochastic processes shape sessile #cryptobenthic communities at multiple spatial scales around Réunion Island—key insights for reef conservation. #Betadiversity #ARMS .

Does oyster aquaculture affect underwater grass habitat? A new study shows sometimes it does, sometimes it doesn't. It depends on the strength of a site's waves and currents and how much the aquaculture gear dampens these physical forces.

Compared to two other Gulf of Mexico shipwrecks, the Deepwater Horizon wreckage hosts a community with unique organisms. We propose wreck age, depth, and the presence of oil as potential factors influencing community assemblage.

New MEPS publication: Using photo identification to determine demographics, fishery interactions and behavioral associations for oceanic whitetip sharks around Hawaii. Read the full article at

Discover the effects of noise on blue mussel larvae, which are of immense economic and ecological importance. Noise from shipping promoted development in suboptimal habitats with higher metabolic costs.
