Expanding our view of the cold-water coral niche and accounting of the ecosystem services of the reef habitat [PDF]

Scientific Reports, 2023
Coral reefs are iconic ecosystems that support diverse, productive communities in both shallow and deep waters. However, our incomplete knowledge of cold-water coral (CWC) niche space limits our understanding of their distribution and precludes a ...

Zooplankton and micronekton respond to climate fluctuations in the Amundsen Sea polynya, Antarctica. [PDF]

Sci Rep, 2019
The vertical migration of zooplankton and micronekton (hereafter 'zooplankton') has ramifications throughout the food web. Here, we present the first evidence that climate fluctuations affect the vertical migration of zooplankton in the ...

Zooplankton and micronekton active flux around the Iberian Peninsula

Frontiers in Marine Science
The biological carbon pump comprises a set of processes that transfer organic carbon from the ocean surface to its depths, playing a vital role in the global carbon cycle.

The impact of a Southern Ocean cyclonic eddy on mesopelagic micronekton

Journal of Geophysical Research: Oceans, 2021
AbstractMesoscale eddies shape the foraging ecology of predators such as marine mammals and seabirds. A growing number of animal tracking studies show that predators alter their swimming, diving, and foraging behavior within mesoscale eddies. However, little is known about how Southern Ocean eddies influence the distribution of mesopelagic micronekton (

Influence of oceanic conditions in the energy transfer efficiency estimation of a micronekton model [PDF]

Biogeosciences, 2020
Micronekton – small marine pelagic organisms around 1–10 cm in size – are a key component of the ocean ecosystem, as they constitute the main source of forage for all larger predators.

Species distribution models describe spatial variability in mesopelagic fish abundance in the Southern Ocean

Frontiers in Marine Science, 2023
IntroductionMesopelagic fishes play a central role in the transfer of energy through open-ocean food webs, particularly in the Southern Ocean where they are both important predators of zooplankton and a key prey group for many higher predators.

Fine-scale vertical structure of sound-scattering layers over an east border upwelling system and its relationship to pelagic habitat characteristics [PDF]

Ocean Science, 2020
Understanding the relationship between sound-scattering layers (SSLs) and pelagic habitat characteristics is a substantial step to apprehend ecosystem dynamics. SSLs are detected on echo sounders representing aggregated marine pelagic organisms.

VERDA: A Multisampler Tool for Mesopelagic Nets

Journal of Marine Science and Engineering, 2023
Different types and systems to discriminate plankton samples at different strata in the water column have been developed in recent decades. For sampling at sufficient depth, opening and closing zooplankton multinets are ideal because there is no ...

Swimbladder properties of Cyclothone spp. in the northeast Atlantic Ocean and the Western Mediterranean Sea

Frontiers in Marine Science, 2023
Non-migratory bristlemouth fishes (Cyclothone spp.) are the most abundant vertebrates on Earth and play an important role in the biological carbon pump by remineralizing organic carbon in deep ecosystems.
