Climate Impacts on Zooplankton Population Dynamics in Coastal Marine Ecosystems
Global ocean ecosystem dynamics zooplankton predators Marine ecosystems reproduction
2015/7/16
The 20-year US GLOBEC (Global Ocean Ecosystem Dynamics) program examined zooplankton populations and their predators in four coastal marine ecosystems. Program scientists learned that environmental co...
Roles of phosphorus and ultraviolet radiation in the strength of phytoplankton–zooplankton coupling in a Mediterranean high mountain lake
Roles of phosphorus ultraviolet radiation
2014/4/17
Ultraviolet solar radiation (UVR) and atmospheric nutrient inputs associated with aerosols are major
worldwide stressors that simultaneously affect species and the interaction among them. A 2 3 5 fie...
Lake-wide distributions of temperature, phytoplankton, zooplankton, and fish in the pelagic zone of a large lake
temperature phytoplankton zooplankton
2014/4/18
We studied three-dimensional distribution patterns of temperature, phyto- and zooplankton, and fish in the
large, prealpine Lake Constance during spring 2007. A strong westerly wind induced an intens...
Climatic forcing of zooplankton dynamics is stronger during low densities of planktivorous fish
Climatic forcing of zooplankton dynamics planktivorous fish
2014/4/18
We analyze interannual variation in zooplankton biomass in the southwestern Barents Sea in spring (May) and
summer (June–July) 1959–1993. Using a threshold modeling approach, we quantify spatial, cli...
Quantification of zooplankton trophic position in the North Pacific Subtropical Gyre using stable nitrogen isotopes
zooplankton trophic position North Pacific Subtropical Gyre
2014/4/17
We quantify the trophic positions of subtropical open-ocean zooplankton species using amino acid–specific
(AA) stable nitrogen isotopic compositions. We model animal trophic position by computing tro...
Effect of zooplankton-mediated trophic cascades on marine microbial food web components (bacteria, nanoflagellates, ciliates)
zooplankton-mediated trophic marine microbial food
2014/4/17
To examine the grazing effects of copepod-dominated mesozooplankton on heterotrophic microbial
communities, four mesocosm experiments using gradients of zooplankton abundance were carried out at a
c...
A standard protocol for stable isotope analysis of zooplankton in aquatic food web research using mass balance correction models
stable isotope analysis zooplankton
2014/4/22
Stable isotope analysis has become a crucial tool for aquatic food web ecologists, but a lack of methodological
standardization hinders comparisons between studies. One methodological inconsistency i...
Major contribution from littoral crustaceans to zooplankton species richness in lakes
littoral crustaceans zooplankton species
2014/5/5
A study of pelagic and littoral species richness among microcrustaceans in 2,466 Norwegian lakes recorded 120
crustacean species: 77 cladocerans, 31 cyclopoids, and 12 calanoids, respectively. Very f...
Unsynchronized and synchronized vertical migration of zooplankton in a high arctic fjord
Unsynchronized synchronized vertical
2014/5/5
We measured vertical migration of zooplankton in an arctic fjord at 79uN between June and September 2002
and transcending a period of continuous illumination to one of true day and night to investiga...
The role of climate in shaping zooplankton communities of shallow lakes
shaping zooplankton communities lakes
2014/5/13
We analyzed data from 81 shallow European lakes, which were sampled with standardized methods, for combined
effects of climatic, physical, and chemical features of food-web interactions, with a speci...
Reproduction as one of the main causes of temporal variability in the elemental composition of zooplankton
Reproduction temporal variability
2014/5/13
With the aim to determine the contribution of development and reproduction to the variability in the elemental
composition of zooplankton, we measured the carbon (C), hydrogen (H), nitrogen (N), and ...
Changes to zooplankton community structure following colonization of a small lake by Leptodora kindti
zooplankton colonization
2014/5/16
The predaceous cladoceran Leptodora kindti (Focke) became established in Third Sister Lake, Michigan, after
individuals escaped from experimental enclosures in 1987. By 1988, the Leptodora population...
Physical, chemical, and biotic effects on arctic zooplankton communities and diversity
Physical chemical biotic effects
2014/5/16
We examined how physical and chemical factors and fish populations affected the presence and density of
zooplankton species in 104 Alaskan arctic lakes. Five fish species and nine zooplan...
Mechanisms, effects, and scales of dispersal in freshwater zooplankton
Mechanisms effects freshwater zooplankton
2014/5/16
The distribution of organisms can be regulated by local environmental factors and regional processes such as
dispersal. Here, we review recent work on the role of dispersal for generating population ...
Testing zooplankton food limitation across gradients of depth and productivity in small stratified lakes
Testing zooplankton food limitation productivity
2014/5/16
We examined the significance of vertical structure in lake plankton to grazer-resource coupling by quantifying
how the intensity and mechanism of grazer food limitation varies with depth. We us...
