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

Coarse-scale vertical distribution of pelagic amphipods in two contrasting seasons of the southern Gulf of Mexico

Frontiers in Marine Science
In the oceans, ecological analyses of pelagic amphipods have mainly focused on the epipelagic zone with few studies in the deep waters. In this study, a coarse-scale vertical analysis, between 0 and 1000 m depth, was performed in the southern Gulf of ...

Changes in DOM Quality Determine Prokaryotic Activities and Extracellular Release in the NW Mediterranean Sea: An Experimental Approach

Environmental Microbiology Reports, Volume 18, Issue 3, June 2026.
Changes in DOM composition influence prokaryotic species growth in the Mediterranean Sea, shaping their metabolic responses and organic matter processing. In our study, higher DOP consumption and alkaline phosphatase activity led to the accumulation of recalcitrant DOM, highlighting how microbial community shifts drive distinct pathways in carbon ...

Diazotroph‐Driven 210Po Scavenging Reveals a Potential Radiotracer for Marine Nitrogen Fixation

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The role of phytoplankton, particularly diazotrophs, in affecting in situ 210Po scavenging has been little investigated. Here, we first report an enhanced 210Po deficit in a cyclonic eddy core relative to its edge in the subtropical Pacific, coinciding with an elevated integrated nitrogen fixation rate (NFR).

Gradients of bacteria in the oceanic water column reveal finely-resolved vertical distributions.

PLoS ONE
Bacterial communities directly influence ecological processes in the ocean, and depth has a major influence due to the changeover in primary energy sources between the sunlit photic zone and dark ocean.

Using 228Th/228Ra Disequilibrium to Constrain Particulate Organic Carbon Export From the Upper Twilight Zone of the Northern South China Sea

Geochemistry, Geophysics, Geosystems, 2023
We utilized the 228Th/228Ra and 234Th/238U disequilibrium methods to estimate the export of particulate organic carbon (POC) from the upper twilight zone in the northern South China Sea during four cruises from August 2009 to May 2011, covering an entire
