Using the Diet Composition of Adult Chinook Salmon to Understand the Regional Structure of Salish Sea Forage Communities

Fisheries Oceanography, Volume 35, Issue 4, Page 565-579, July 2026.
ABSTRACT Small pelagic fish and other forage species are patchily distributed over space and time, resulting in variable foraging conditions experienced by their predators. The high‐resolution data necessary to understand the spatiotemporal structure of forage communities are challenging to collect with expensive fishery‐independent surveys, meaning ...

Killer Whales in the Central Tropical Pacific: Occurrence, Resightings, Morphology, and Acoustics

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT Compared to their well‐studied coastal temperate counterparts, killer whales (Orcinus orca) in tropical‐subtropical and oceanic areas are under‐documented. We used sighting, photo‐identification, and acoustic data of killer whales in the central tropical Pacific (CTP), collected from multiple platforms between 2002 and 2023, to assess their ...

Foraging Ecology and Fisheries Interactions of Common Bottlenose Dolphins (Tursiops truncatus) Inferred From Strandings in Western Iberian Atlantic Waters

Marine Mammal Science, Volume 42, Issue 3, July 2026.
ABSTRACT The common bottlenose dolphin (Tursiops truncatus) is a resident species along the Portuguese mainland coast, yet knowledge of its stranding patterns and feeding ecology is scarce. This study presents a comprehensive assessment of strandings (n = 264, from 1980 to 2019) and feeding ecology based on stomach content analysis (n = 43 from 1997 to

Zooplankton, micronekton and biological pump: Beyond the mesopelagic zone [PDF]

, 2012
Migrant biota transports carbon to the mesopelagic zone due to their feeding at the shallower layers and their defecation, respiration, excretion and mortality at depth.

Light comfort zone in a mesopelagic fish emerges from adaptive behaviour along a latitudinal gradient [PDF]

, 2019
Throughout the oceans, small fish and other micronekton migrate between daytime depths of several hundred meters and near-surface waters at night. These diel vertical migrations of mesopelagic organisms structure pelagic ecosystems through trophic ...

Marine growth along the mesopelagic zone

Floating wind farms in offshore areas in the world marks a significant stride towards harnessing renewable wind power from deeper oceanic expanses. While the technology is still evolving, its potential as a key player in the renewable energy landscape is evident.

Light-sensitive vertical migration of the Japanese eel Anguilla japonica revealed by real-time tracking and its utilization for geolocation. [PDF]

PLoS ONE, 2015
Short-time tracking (one to eight days) of the Japanese eel (Anguilla japonica) using ultrasonic transmitter was performed in the tropical-subtropical area adjacent to the spawning area and temperate area off the Japanese Archipelago. Of 16 eels (11 wild

Unifying Retaria Research: A Common Framework for Studying Foraminifera and Radiolaria

BioEssays, Volume 48, Issue 6, June 2026.
Research on Foraminifera and Radiolaria has predominantly focused on their fossil remains. This synthesis identifies the “Big Five” disciplines of a unified Retaria research: diversity and evolution, ecology, life cycles, and ecosystem roles, highlighting this lineage as a model system for understanding life's resilience in a rapidly changing planet ...

Individual specialization and temporal changes in Antarctic fur seal trophic ecology from a multi‐tracer approach

Ecosphere, Volume 17, Issue 6, June 2026.
Abstract Substantial individual variation in diet and foraging strategies can exist within populations. These differences can enhance individual foraging efficiency, reduce intraspecific competition, and provide fitness advantages that increase the resilience of a population.

Whale foraging seascapes: Advective prey aggregation mechanisms predict North Atlantic right whale foraging grounds

Limnology and Oceanography, Volume 71, Issue 6, June 2026.
Abstract During foraging activity, baleen whales are generally dependent on the occurrence of dense prey patches. These are largely influenced by the interaction between ocean currents and the vertical distribution of individual prey. Identifying the spatio‐temporal dynamics of the areas where prey form dense aggregations, at submeso scale (~ 10 km ...
