Ingestion, faecal pellet and egg production rates of Calanus helgolandicus feeding coccolithophorid versus non-coccolithophorid diets.
Ingestion rates, faecal pellet and egg production were obtained in laboratory experiments with females of the copepod Calanus helgolandicus collected from the English Channel in November 1994. Five different algal monocultures were used as food: Prorocentrum micans (30 µm ESD), Thalassiosira weissflogii (13 µm ESD), Dunaliella tertiolecta (7 µm ESD), Emiliania huxleyi (5 µm ESD) and Coccolithus...
متن کاملGenomic approaches to detecting thermal stress in Calanus finmarchicus (Copepoda: Calanoida)
Zooplankton may be subjected to physiological stress as they encounter rapid and large changes in temperature through vertical migration or transfer into different water masses. Induction of one or more heat shock proteins (hsp) is a common protective response to thermal stress in organisms. We looked for evidence for such a response in Calanus finmarchicus. We compared hsp70 expression in cope...
متن کاملAcrocalanus gracilis (Copepoda: Calanoida) development and production in the Timor Sea
We investigated the juvenile development of the calanoid copepod Acrocalanus gracilis in the Timor Sea. The development was characterized by the calculation of stage-specific duration, median development time, moulting period duration, moult and growth rates. The morphometry of the experimental and wild populations were compared. Food concentrations in the experiment were lower than those in th...
متن کاملMulti-Gene Analysis Reveals a Lack of Genetic Divergence between Calanus agulhensis and C. sinicus (Copepoda; Calanoida)
The discrimination and taxonomic identification of marine species continues to pose a challenge despite the growing number of diagnostic metrics and approaches. This study examined the genetic relationship between two sibling species of the genus Calanus (Crustacea; Copepoda; Calanidae), C. agulhensis and C. sinicus, using a multi-gene analysis. DNA sequences were determined for portions of the...
متن کاملSpatial Modeling of Calanus finmarchicus and Calanus helgolandicus: Parameter Differences Explain Differences in Biogeography
The North Atlantic copepods Calanus finmarchicus and C. helgolandicus are moving north in response to rising temperatures. Understanding the drivers of their relative geographic distributions is required in order to anticipate future changes. To explore this, we created a new spatially explicit stage-structured model of their populations throughout the North Atlantic. Recent advances in underst...
