Relationships between acoustic scattering layers and ocean stratification: An acoustic approach to estimate mixed layer depth

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Ocean stratification, measured as mixed layer depth (MLD), is an important feature that influences many processes in the ocean; for example, by mediating the fluxes of momentum, heat and crucially key gases such as CO2 and oxygen from the atmosphere into the water column and vice versa. The conventional methods to measure stratification (e.g.,

The feeding ecology of some zooplankters that are important prey items of larval fish [PDF]

open access: yes, 1984
Diets of 76 species of fish larvae from most oceans of the world were inventoried on the basis of information in 40 published studies. Although certaln geographlc, size- and taxon-specific patterns were apparent, certain zooplankton taxa appeared in the ...

Reproduction and respiration of a climate change indicator species: effect of temperature and variable food in the copepod Centropages chierchiae [PDF]

open access: yes, 2013
The abundance of the calanoid copepod Centropages chierchiae has increased at the northern limits of its distribution in recent decades, mainly due to oceanic climate forcing, suggesting this as a key species in monitoring climate change.

Improved COI taxonomic assignment workflow enhances detection of invertebrates in environmental DNA

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Environmental DNA (eDNA) metabarcoding is an increasingly popular and powerful tool in ecology, offering a non‐invasive method to assess biodiversity and monitor ecosystem health across diverse environments. While the mitochondrial cytochrome c oxidase subunit I (COI) gene is one of the most widely used markers for studying eukaryotic ...

First De Novo Transcriptome of the Copepod Rhincalanus gigas from Antarctic Waters

open access: yesBiology, 2020
Antarctic waters are the largest almost untapped diversified resource of our planet. Molecular resources for Antarctic organisms are very limited and mostly represented by sequences used for species genotyping.

The IceShark, an effective method for sampling plankton under sea ice

open access: yesLimnology and Oceanography: Methods, EarlyView.
Abstract Seasonal sea ice plays a crucial role in shaping coastal ecosystem dynamics throughout the circumpolar region. Of particular interest to oceanographers is the ice‐ocean interface which functions as a multidimensional habitat, supporting both sympagic algae and pelagic phytoplankton in the under‐ice surface waters.

Environmental Stress Responses and Experimental Handling Artifacts of a Model Organism, the Copepod Acartia tonsa (Dana)

open access: yesFrontiers in Marine Science, 2018
Handling animals during experiments potentially affects the differential expression of genes chosen as biomarkers of sub-lethal stress. RNA sequencing was used to examine whole-transcriptome responses caused by laboratory handling of the calanoid copepod,

Climate Change May Restrict the Predation Efficiency of Mesocyclops aspericornis (Copepoda: Cyclopidae) on Aedes aegypti (Diptera: Culicidae) Larvae

open access: yesInsects, 2020
(1) Dengue is the most spread mosquito-borne viral disease in the world, and vector control is the only available means to suppress its prevalence, since no effective treatment or vaccine has been developed.

The Advantages of Inorganic Fertilization for the Mass Production of Copepods as Food for Fish Larvae in Aquaculture

open access: yesLife, 2022
Copepods are commonly used as live feed for cultured fish larvae, but the current mass production method using organic fertilizers cannot meet the market demand for copepods.

Seasonal variations in planktonic food web structure affect stability by shifting the distribution of energy fluxes

open access: yesOikos, EarlyView.
Seasonality in temperate ecosystems shapes species phenology, influencing interactions and food web structure. Variations in species richness and biomass affect trophic interaction strength, a crucial factor for community stability, which can be assessed through energy fluxes – an essential indicator of ecosystem function.
