Spatiotemporal analysis of micronekton biomass at the mouth of the River Plate

Acta Scientiarum: Biological Sciences
The region adjacent to the River Plate is renowned for its fishing activity and abundant biodiversity. Both are closely linked to the significant local river flows responsible for fertilizing extensive marine areas.

Zooplankton and micronekton active flux around the Iberian Peninsula [PDF]

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.

Exploring the future of the Coral Sea micronekton [PDF]

Progress in Oceanography, 2021
Abstract Ecosystem models forced by future climate simulations outputs from the Coupled Model Intercomparison Project Phase 5 (CMIP5) simulate a substantial decline of tropical marine animal biomass over the course of the 21st century. Regional projections are however far more uncertain because of well-known biases common to most CMIP5 historical ...

Differences in the trophic ecology of micronekton driven by diel vertical migration. [PDF]

Limnol Oceanogr, 2019
AbstractMany species of micronekton perform diel vertical migrations (DVMs), which ultimately contributes to carbon export to the deep sea. However, not all micronekton species perform DVM, and the nonmigrators, which are often understudied, have different energetic requirements that might be reflected in their trophic ecology.

Trophic structure of micronekton in the Northwest Pacific Ocean

Frontiers in Marine Science, 2022
IntroductionStable isotope analysis has been widely used in the study of the trophic structure of marine micronekton in recent years.MethodsIn this study, the carbon and nitrogen stable isotope values of fish, cephalopod, shrimp and zooplankton species ...

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.

Modeling the contribution of micronekton diel vertical migrations to carbon export in the mesopelagic zone [PDF]

Biogeosciences
Micronekton plays a significant but often overlooked role in carbon transport within the ocean. Using a one-dimensional trait-based model, we simulated the diel vertical migrations (DVMs) of micronekton and their carbon production through respiration ...

Biogeography of Micronekton Assemblages in the Natural Park of the Coral Sea [PDF]

Frontiers in Marine Science, 2020
Mesopelagic resources are central to the ecosystem but remain poorly studied mainly due to the lack of observations. This paper investigates the assemblages of micronekton organisms and their habitat in the Natural Park of the Coral Sea around New ...

Seasonal oceanography from physics to micronekton in the south-west Pacific [PDF]

Deep Sea Research Part II: Topical Studies in Oceanography, 2015
Tuna catches represent a major economic and food source in the Pacific Ocean, yet are highly variable. This variability in tuna catches remains poorly explained. The relationships between the distributions of tuna and their forage (micronekton) have been mostly derived from model estimates.

Synthetic pelagic biomass size spectra of the tropical and subtropical Atlantic

Ecosphere
Synthetic normalized biomass size spectra (NBSS) comprising non‐synoptically sampled phytoplankton, meso‐ and macrozooplankton, and micronekton including mesopelagic fishes were explored to analyze pelagic community structure in seven regions of the ...
