UV-enhanced fish predation and the differential migration of zooplankton in response to UV radiation and fish
UV-enhanced fish predation zooplankton
2014/4/18
The intensity and spectral composition of visible light are known to influence fish predation on zooplankton.
However, in clear-water systems, ultraviolet (UV) radiation (UVR) may also influence fish...
Calculations of Differential Kinematic Properties from Lagrangian Observations in the Western Caribbean Sea
Differential Kinematic Properties Lagrangian Observations Western Caribbean Sea
2009/3/24
Observations of the motions of drifter clusters were made in the western Caribbean Sea during the summer of 1971. By two independent analyses of the relative motions of a cluster, two time series of h...
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...
Rotating Convection Driven by Differential Bottom Heating
Rotating Convection Driven Differential Bottom Heating
2008/7/11
Convection experiments were carried out in a rectangular tank as a model of oceanic meridional overturning circulation. The objective was finding a relation between the meridional heat flux and therma...
Intrusions in Double-Diffusively Stable Arctic Waters: Evidence for Differential Mixing?
Double-Diffusively Stable Arctic Waters Differential Mixing?
2008/6/6
Intrusions like those observed in double-diffusively stable regions of the Arctic Ocean can grow from uniform ambient temperature and salinity gradients if diapycnal mixing of these two components dif...
Differential effects of phosphorus limitation on cellular metals in Chlorella and Microcystis
phosphorus limitation Chlorella Microcystis
2014/4/21
We investigated the effect of phosphate bioavailability on cellular metal quotas in two species of freshwater
phytoplankton (the eukaryote Chlorella sp. UTCC522 and the cyanobacterium Microcystis sp....
Differential grazer-mediated effects of high summer temperatures on pico- and nanoplankton communities
Differential grazer-mediated high summer temperatures pico nano plankton communities
2014/4/21
We investigated the role of a macrograzer (the filter feeding musselDreissena polymorpha) in mediating effects of high summer temperatures on the dominant components of natural river plankton (i.e., b...
Sex-related differential mortality of a marine copepod exposed to a toxicdinoflagellate
Sex-related differential mortality marine copepod exposed toxicdin of lagellate
2014/4/18
In this study we hypothesized that the sexes of the copepod Acartia hudsonicaexperience different mortalities when exposed to the toxic dinoflagellate Alexandrium fundyense. In laboratory experiments,...
Nutrient quality drives differential phytoplankton community composition on the southwest Florida shelf
Nutrient quality drives differential phytoplankton community composition southwest Florida shelf
2014/4/22
During May 2003, the dry season, the southwest Florida shelf was surveyed for nutrient concentrations and phytoplankton community composition concurrently with plankton nutritional and physiological s...
Molecular quantification of differential ingestion and particle trapping rates by the appendicularian Oikopleura dioica as a function of prey size and shape
Molecular quantification of differential ingestion particle trapping rates the appendicularian Oikopleura dioica function of prey size and shape
2014/4/22
To investigate whether particles are ingested or merely trapped in the house of the appendicularian Oikopleura dioica, we developed a real-time quantitative polymerase chain reaction (qPCR) assay and ...
Differential effect of algal- and soil-derived dissolved organic matter on alpine lake bacterial community composition and activity
algal- and soil-derived dissolved organic composition activity
2014/5/5
We studied the effects of algal- and soil-derived dissolved organic matter (DOM) enrichments on the activity
and community composition of bacterioplankton in an alpine lake. The effects of the DOM so...
Differential effects of phosphorus and fatty acids on Daphnia growth and reproduction
phosphorus and fatty acids Daphnia growth and reproduction
2014/5/8
We investigated the effects of various mineral and biochemical limitations on Daphnia magna. These daphniids have much lower saturation thresholds for growth for the polyunsaturated fatty acids (PUFA)...
Differential uptake of dissolved and particulate organic carbon by the marine mussel Perna viridis
Differential uptake of dissolved particulate organic carbon marine mussel Perna viridis
2014/5/19
We used radiotracers in laboratory experiments to determine the organic carbon uptake by the marine mussel Perna viridis from different diets (phytoplankton and detritus) and from the dissolved phase ...
Life cycle plasticity and differential growth and development in marine and lacustrine populations of an Antarctic copepod
Life cycle plasticity differential growth and development marine and lacustrine populations Antarctic copepod
2014/5/14
We examined life cycle plasticity in two populations of the copepod Paralabidocera antarctica, one of which inhabits the coastal sea ice belt of Antarctica and the other of which has been isolated in ...

Deep-water renewalLake Issyk-Kul driven
2014/5/21
During two field campaigns on Lake Issyk-Kul in March and August 2001, 179 high-resolution conductivitytemperature-depth profiles were measured, along with profiles of dissolved oxyg...
