Sapphirinid copepods as predators of doliolids: Their role in doliolid mortality and sinking flux
predators of doliolids Sapphirinid copepods
2014/4/2
A substantial export flux of particulate organic carbon linked to sinking dead copepods during winter 2007–2008 in the Amundsen Gulf (southeastern Beaufort Sea, Arctic Ocean)
southeastern Beaufort Sea particulate organic carbon
2014/4/4
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...

Significant contribution of passively sinking copepods to the downward export flux in Arctic waters
Significant contribution passively sinking copepods downward export flux Arctic waters
2014/4/17
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 influence of river plume dynamics on trace metal accumulation in calanoid copepods
iver plume dynamics calanoid copepods
2014/4/17
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...
Stoichiometric dietary constraints influence the response of copepods to ultraviolet radiation-induced oxidative stress
Stoichiometric dietary constraints the response of copepods ultraviolet radiation-induced oxidative stress
2014/4/17
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...
Does predation control adult sex ratios and longevities in marine pelagic copepods?
predation contro adult sex ratios longevities marine pelagic copepods
2014/4/16
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...
Mate limitation in an estuarine population of copepods
Mate limitation estuarine population copepods
2014/4/18
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...
Escape strategies in co-occurring calanoid copepods
Escape strategies co-occurring calanoid copepods
2014/4/21
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 ...
Scaling of feeding in marine calanoid copepods
Scaling of feeding marine calanoid copepods
2014/4/23
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...
Production of dissolved organic carbon by sloppy feeding in the copepods Acartia tonsa, Centropages typicus, and Temora longicornis
Production of dissolved organic carbon sloppy feeding the copepods Acartia tonsa Centropages typicus Temora longicornis
2014/4/22
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...
Dimethyl sulfide triggers search behavior in copepods
Dimethyl sulfide triggers search copepods
2014/5/4
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...
A comparative population genetic study on calanoid freshwater copepods: Investigation of isolation-by-distance in two Eudiaptomus species with a different potential for dispersal
A comparative population genetic study calanoid freshwater copepods
2014/4/23
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....
Response of copepods to physical gradients associated with structure in the ocean
Response of copepods physical gradients associated with structure the ocean
2014/5/13
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...
Benthic life in the pelagic: Aggregate encounter and degradation rates by pelagic harpacticoid copepods
Benthic life in the pelagic Aggregate encounter degradation rates pelagic harpacticoid copepods
2014/5/9
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...
