Cascading effects of calanoid copepod functional groups on the biological carbon pump in the subtropical South Atlantic

Frontiers in Marine Science, 2022
Life strategies, ecophysiological performances and diel vertical migration (DVM) of zooplankton key species affect the efficiency and strength of the biological carbon pump (BCP).

Depth-related patterns in microbial community responses to complex organic matter in the western North Atlantic Ocean [PDF]

Biogeosciences, 2022
Oceanic bacterial communities process a major fraction of marine organic carbon. A substantial portion of this carbon transformation occurs in the mesopelagic zone, and a further fraction fuels bacteria in the bathypelagic zone. However, the capabilities

The protist community traces seasonality and mesoscale hydrographic features in the oligotrophic Sargasso Sea

Frontiers in Marine Science, 2022
Protists represent the majority of the eukaryotic diversity in the oceans. They have different functions in the marine food web, playing essential roles in the biogeochemical cycles.

An 18S V4 rRNA metabarcoding dataset of protist diversity in the Atlantic inflow to the Arctic Ocean, through the year and down to 1000 m depth [PDF]

Earth System Science Data, 2021
Arctic marine protist communities have been understudied due to challenging sampling conditions, in particular during winter and in deep waters. The aim of this study was to improve our knowledge on Arctic protist diversity through the year, in both the ...

Measures and models of visual acuity in epipelagic and mesopelagic teleosts and elasmobranchs

Journal of Comparative Physiology A, 2023
AbstractEyes in low-light environments typically must balance sensitivity and spatial resolution. Vertebrate eyes with large "pixels" (e.g., retinal ganglion cells with inputs from many photoreceptors) will be sensitive but provide coarse vision. Small pixels can render finer detail, but each pixel will gather less light, and thus have poor signal ...

Using a recreational grade echosounder to quantify the potential prey field of coastal predators.

PLoS ONE, 2019
Quantifying the distribution of prey greatly improves models of habitat use by marine predators and can assist in determining threats to both predators and prey.
