Vertical distribution and population dynamics of copepods by dynamic optimization
Vertical distribution and population dynamics of copepods are viewed as a consequence of individual maximization of reproductive value (RV). RV for all individuals of all size classes (stages) and conditions (physiological states) is found by dynamic programming, and specifies a trajectory of optimal habitats in time and space. The optimal habitat is found by balancing the risk of predation and...
متن کاملVertical distribution patterns of copepods, chlorophyll, and production in northeastern Baffin Bay
High resolution vertical distributions of chlorophyll and zooplankton were collected with an instrumented Batfish vehicle in northeastern Baffin Bay. The dominant copepod species wc1.e Calanusfinmllrchicus, Calanus glncinlis, and Calanus hyperlporeus V and VI. Copepod layers consisting of C. jkmclr-chicus and C. glncialis were commonly situated ~3-4 m above the chlorophyll maximum in a depth re...
متن کاملOntogenetic vertical distribution patterns in small copepods: field observations and model predictions
We investigated fine-scale (5m, 4h) speciesand stage-specific (N1 to C6) distributions of common copepods at an anchor station in a Swedish fjord during two 24 h periods in October 1997. Generally, both calanoid and cyclopoid nauplii were found near the surface, while copepodids stayed deeper in the water column. No diurnal migration was observed. To analyze the observed distributions, we combi...
متن کاملDistribution and production of plankton communities in the subtropical convergence zone of the Sargasso Sea. II. Protozooplankton and copepods
The oligotrophic Sargasso Sea in the western part of the North Atlantic Ocean is influenced by a complex set of oceanographic features that might introduce nutrients and enhance productivity in certain areas. To increase our understanding of the variability in plankton communities and to determine the potential reasons why Atlantic eels Anguilla spp. use this area for spawning, we investigated ...
متن کاملVertical distribution of phytoplankton biomass, production and growth in the Atlantic subtropical gyres
Ninety-four stations were sampled in the Atlantic subtropical gyres during 10 cruises carried out between 1995 and 2001, mainly in boreal spring and autumn. Chlorophyll a (Chl-a) and primary production were measured during all cruises, and phytoplankton biomass was estimated in part of them. Picoplankton (o2mm) represented 460% of total Chl-a concentration measured at the surface, and their con...
