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

Profundum solomoni (Amphipoda: Uristidae) Exhibits a Disjunct Geographic Distribution at Hadal Depths Across the San Cristobal Trench, Santa Cruz Trench and Nova Canton Trough

Zoologica Scripta, Volume 55, Issue 4, Page 639-651, July 2026.
ABSTRACT Hadal environments (> 6000 m ocean depths) are often viewed as isolated locations with high species endemism due to limited dispersal. However, molecular studies continue to reveal greater complexity that questions historical perceptions. Recent population genetic studies focused on scavenging amphipods have identified broadly distributed ...

Cooperative Associations Between Fishes and Bacteria: The Influence of Different Ocean Fishes on the Gut Microbiota Composition

Fishes
Gut microbial communities perform a multitude of physiological functions for their hosts; however, the drivers and distribution patterns of microbiota in wild animals remain largely underexplored.

Observations of shifts in cetacean distribution in the Norwegian Sea

Frontiers in Ecology and Evolution, 2015
This study aimed to assess possible shifts in distributional patterns of cetaceans residing in the Norwegian Sea, and if possible relate the distribution to their feeding ecology during the summer seasons of 2009, 2010 and 2012.

"Once upon a time in the Mediterranean" long term trends of Mediterranean fisheries resources based on fishers' Traditional Ecological Knowledge.

PLoS ONE, 2015
We investigate long-term changes in the Mediterranean marine resources driving the trawl fisheries by analysing fishers' perceptions (Traditional Ecological Knowledge, TEK) throughout the Mediterranean Sea during the last 80 years.

Mercury and Selenium Trophic Transfer in the Mexican California Current Ecosystem Using a Top Predator as a Model

Fishes
Research on the trophic transfer of trace elements in food chains, particularly toxic elements like mercury (Hg) and essential elements like selenium (Se), is crucial for understanding their impact on human health.
