First report of infestation by a parasitic copepod (Pennella balaenopterae) in a harbour porpoise (Phocoena phocoena) from the Aegean Sea: a case report
copepod Pennella balaenopterae harbour porpoise ectoparasite southern Aegean Sea
2015/4/17
An adult, female harbour porpoise (Phocoena phocoena relicta) was found stranded on the southern Aegean Sea coast of Turkey. Thirteen holes made by copepods were observed on the lateral sides of the p...
Feeding rates and prey : predator size ratios of the nauplii and adult females of the marine cyclopoid copepod Oithona davisae
predator size Feeding rates and prey
2014/11/28
We studied the feeding behavior of the nauplii and adult females of the marine cyclopoid copepod Oithona
davisae in the laboratory. Functional response experiments showed that O. davisae can feed on ...
Threshold-driven shifts in two copepod species: Testing ecological theory with observational data
Threshold-driven shifts two copepod species Testing ecological theory observational data
2014/4/2
We used an observed abrupt shift in the dominance pattern of two coexisting copepod species in Müggelsee, a shallow eutrophic lake in Germany, to investigate mechanisms leading to this shift, by embed...
Functional response of carbon absorption efficiency in the pelagic calanoid copepod Acartia tonsa
Functional response carbon absorption efficiency the pelagic calanoid copepod Acartia tonsa
2014/4/17
We constructed a general relationship between prey concentration and absorption efficiency (AE; previously termed assimilation efficiency) in the cosmopolitan calanoid copepod Acartia tonsa. The relat...
Density-dependent nutritional value of the dinoflagellate Cochlodinium polykrikoides to the copepod Acartia tonsa
Density-dependent nutritional value dinoflagellate Cochlodinium polykrikoides copepod Acartia tonsa
2014/4/17
The nutritional value of the dinoflagellate Cochlodinium polykrikoides to the copepod Acartia tonsa was evaluated over a range of ecologically relevant cell densities. Based on egg production rate, eg...
How to surprise a copepod: Strike kinematics reduce hydrodynamic disturbance and increase stealth of suction-feeding fish
Strike kinematics reduce hydrodynamic disturbance increase stealth suction-feeding fish
2014/4/17
To capture prey with suction, fish must get sufficiently close to their prey to allow the suction flow to overwhelm the prey and draw it into the mouth. Both swimming towards the prey and suction flow...
Dead in the water: The fate of copepod carcasses in the York River estuary, Virginia
Dead in the water The fate of copepod carcasses the York River estuary Virginia
2014/4/16
Using laboratory and field experiments we investigated three fates of copepod carcass organic matter in the York River estuary, Virginia: ingestion by planktivores (necrophagy), microbial decompositio...
Disrupted seasonal clockwork in the population dynamics of a freshwater copepod by climate warming
Disrupted seasonal clockwork the population dynamics freshwater copepod climate warming
2014/4/17
Life history responses are expected to accompany climate warming, yet little is known how long-term effects of climate and environmental change affect the seasonal dynamics of planktonic organisms. We...
Sex-related differential mortality of a marine copepod exposed to a toxic dinoflagellate
Sex-related differential mortality marine copepod exposed toxic dinoflagellate
2014/4/21
In this study we hypothesized that the sexes of the copepod Acartia hudsonica experience different mortalities when exposed to the toxic dinoflagellate Alexandrium fundyense. In laboratory experiments...
ANALYSIS OF CLIMATE CHANGE SCENARIOS BASED ON MODELLING OF THE SEASONAL DYNAMICS OF A DANUBIAN COPEPOD SPECIES
Cyclops vicinus geographical analogy hydrobiology simulation modelling
2010/3/25
Climate change is one of the most crucial ecological problems of our age with great influence.
Seasonal dynamics of aquatic communities are — among others — regulated by the climate, especially by te...
Diel periodicity in both sei whale vocalization rates and the vertical migration of their copepod prey observed from ocean gliders
Diel periodicity both sei whale vocalization rates the vertical migration their copepod prey observed ocean gliders
2014/5/16
The daily activity cycles of marine predators may be dictated in large part by the timing of prey availability. For example, recent studies have observed diel periodicity in baleen whale vocalization ...
Population dynamics of a freshwater calanoid copepod: Complex responses to changes in trophic status and climate variability
Population dynamics a freshwater calanoid copepod Complex responses changes in trophic status climate variability
2014/4/21
The long-term dynamics of the calanoid copepod Eudiaptomus gracilis were analyzed in Lake Constance, a deep lake that has been influenced strongly by changes in trophic status and climate variability ...
Copepod reproduction is unaffected by diatom aldehydes or lipid composition
Copepod reproduction unaffected diatom aldehydes lipid composition
2014/4/21
We investigated whether reduced reproductive success of copepods fed with diatoms was related to nutritional imbalances with regard to essential lipids or to the production of inhibitory aldehydes. In...
Production, oxygen respiration rates, and sinking velocity of copepod fecal pellets: Direct measurements of ballasting by opal and calcite
Production oxygen respiration rates sinking velocity copepod fecal pellets Direct measurements ballasting by opal calcite
2014/4/21
Production, oxygen uptake, and sinking velocity of copepod fecal pelletsegested byTemora longicorniswere measured using a nanoflagellate (Rhodomonassp.), a diatom (Thalassiosira weissflogii), or a coc...
