Grazing, egg production and carbon budgets for Calanus finmarchicus across the Fram Strait

Frontiers in Marine Science, 2022
Calanoid copepods comprise around 90% of Arctic zooplankton biomass and are fundamental to the ecological and biogeochemical functioning of high-latitude pelagic ecosystems.

Seasonal Variations in the Biodiversity, Ecological Strategy, and Specialization of Diatoms and Copepods in a Coastal System With Phaeocystis Blooms: The Key Role of Trait Trade-Offs

Frontiers in Marine Science, 2021
Although eutrophication induced by anthropogenic nutrient enrichment is a driver of shifts in community composition and eventually a threat to marine biodiversity, the causes and consequences on ecosystem functioning remain greatly unknown. In this study,

Mortality of marine planktonic copepods : global rates and patterns

, 2002
Using life history theory we make predictions of mortality rates in marine epi-pelagic copepods from field estimates of adult fecundity, development times and adult sex ratios.

Abundance, composition, and development of zooplankton in the Subarctic Iceland Sea in 2006, 2007, and 2008 [PDF]

, 2012
A large-scale study of zooplankton from surface waters and depth-stratified sampling at selected sites in the Iceland Sea was conducted during the years 2006–2008.

Does predation control adult sex ratios and longevities in marine pelagic copepods?

, 2010
We assess the causes of adult sex ratio skew in marine pelagic copepods by examining changes in these ratios between the juveniles and adults, sexual differences in juvenile stage durations, and mortality rates of adults in the field and laboratory (when

Sex Reversal in Copepods [PDF]

Nature, 1948
BETWEEN February and June 1947, 20·5 per cent of the males, 3·7 per cent of the females and 0·3 per cent of the copepodids of Pseudocalanus elongatus Boeck, collected from six stations between Flamborough Head and the Dogger Bank, were found to be parasitized by Blastodinium contortum hyalinum Chatton. Almost all the observed parasites were found to be

Microplastics in the menu of Mediterranean zooplankton: Insights from the feeding response of the calanoid copepod Centropages typicus

Marine Ecology, EarlyView., 2023
Abstract Microplastic input into the ocean represents an increasing threat to marine biota and may endanger the functioning of marine ecosystems, especially in semi‐enclosed basins, such as the Mediterranean Sea. The size spectrum of microplastics overlaps with that of nano‐microplankton (2–200 μm), thus potentially misleading suspension‐feeding ...

Zooplankton Community Stability and Environmental Filtering in a Shallow Eutrophic Lake. [PDF]

Ecol Evol
Anthropogenic pressures led to zooplankton shift to small‐bodied dominance, not structural reorganization. Integrated management is crucial for long‐term resilience. ABSTRACT Zooplankton are key regulators of trophic interactions and nutrient cycling in shallow eutrophic lakes and are sensitive indicators of ecological responses to anthropogenic ...

Fecundity of marine planktonic copepods: global rates and patterns in relation to chlorophyll a, temperature and body weight

, 2003
Global rates and patterns of fecundity in marine epipelagic copepods were studied as a function of temperature, body weight of the female and concentration of chlorophyll a.
