In the Arctic Ocean, vertical fluxes of particulate organic carbon (POC) remain low during the dark winter period because POC fluxes are derived from photosynthetic production. Passively sinking dead...

Typically, all undecomposed metazoans found in formalin-poisoned cups of sediment traps are considered to be active intruders (or ‘‘swimmers’’) and are removed to prevent an overestimation of the down...
The concentrations of Ag, Cd, Cu, Hg(II), monomethylmercury (MeHg), Pb, and Zn were measured and modeled in calanoid copepods collected from the Hudson River plume in April 2005 and May 2006. Copepod...
We carried out field experiments in two clear mountain lakes of both hemispheres (Lake Los Ca′ ntaros,Patagonia, Argentina, and Lake La Caldera, Sierra Nevada, Spain) performing a full factorial desig...
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 morta...
We determined the probability of mating as a function of population density in the estuarine copepodAcartia hudsonicaby combining experimental measurements with a simple model. Pairs of unmated copepo...
We show how four co-occurring calanoid copepod species modulate their responses to two contrasting hydrodynamic stimuli. Species-specific patterns in escape behavior included quantitative differences ...
We describe patterns of body size scaling of feeding by marine calanoid copepods based on a literature review. Maximum feeding rates of calanoid copepods, determined in the laboratory, were temperatur...
With 14C-labeled phytoplankton as tracer, dissolved organic carbon (DOC) produced by sloppy feeding was measured for three species of marine copepods (Acartia tonsa, Centropages typicus, and Temora lo...
The oceans are nutritionally dilute, and finding food is a major challenge for many zooplanktonic predators. Chemodetection is necessary for successful preycapture, but little is known about the infoc...
We examined patterns of genetic isolation-by-distance in two sister species of freshwater copepods, Eudiaptomus graciloides and Eudiaptomus gracilis, using the polymorphism of microsatellite markers....
We studied the response of the copepods Acartia tonsa and Temora longicornis to spatial gradients of flow velocity and fluid density to determine whether the presence of physical gradients initiated l...
We measured field abundances, feeding rates, swimming behavior, and particle colonization of two harpacticoids, the pelagic Microsetella norvegica and the semibenthic , to examine (1) if aggregates ha...
