Species-specific encystment patterns in three Baltic cold-water dinoflagellates: The role of multiple cues in resting cyst formation
Species-specific encystment patterns Baltic cold-water dinoflagellates
2014/4/18
The relationships among cellular nutrient status, environmental conditions (temperature and nutrient
availability), and cyst production were studied in batch cultures of three cold-water dinoflagella...
Competition and facilitation between unicellular nitrogen-fixing cyanobacteria and non–nitrogen-fixing phytoplankton species
Competition facilitation unicellular nitrogen-fixing
2014/4/22
Recent discoveries show that small unicellular nitrogen-fixing cyanobacteria are more widespread than
previously thought and can make major contributions to the nitrogen budget of the oceans. We comb...
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...
Response of fish communities in five north temperate lakes to exotic species and climate
Response of fish communities north temperate lakes
2014/5/5
Exotic species invasions and climatic variation that occurred in north central Wisconsin provided the
opportunity to contrast influences of climate and invasive species in shaping fish community dyna...
A new numerical technique for tracking chemical species in a multisource, coastal ecosystem applied to nitrogen causing Ulva blooms in the Bay of Brest (France)
tracking chemical species multisource
2014/4/30
A new numerical technique is presented that allows the tracking of any chemical element from any source in a
simulated foodweb, for instance assessing the proportion of these sources (river loadings,...
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....
A species invasion mediated through habitat structure, intraguild predation, and parasitism
habitat structure intraguild predation
2014/5/19
With field, laboratory, and modeling approaches, we examined the interplay among habitat structure, intraguild
predation (IGP), and parasitism in an ongoing species invasion. Native Gammarus du...
To sink or swim: Variable diapause strategies among Daphnia species
Variable diapause strategies Daphnia species
2014/5/16
Although dormancy is assumed to be fundamental to population persistence in temporary ponds, it has been
suggested that diapause may be less frequent in populations that inhabit permanent lakes. We c...
Nonrandom sexual reproduction and diapausing egg production in a Daphnia hybrid species complex
Nonrandom sexual reproduction
2014/5/16
Sexual reproduction in Daphnia results in the production of diapausing eggs, which are enclosed in a structure
called ephippium. Ephippia, accumulated by sedimentation, can be preserved for decades a...
Millennial-scale relationships of diatom species richness and production in two prairie lakes
2014/5/16
Insight into the causes and consequences of changes in aquatic biodiversity requires an improved understanding
of the nature of the relationships between species richness and ecosystem function over ...
Predation as a factor mediating resource competition among rotifer sibling species
rotifer sibling species Predation
2014/5/14
The relevance of predation as a factor mediating the competitive interaction among ecologically very similar
species is investigated by experimentally analyzing the effect of the copepod predator Dia...
Pelagic species size distributions in lakes: Are they discontinuous?
Pelagic species size distributions lakes
2014/6/9
Aquatic ecologists have many models for size distributions of pelagic communities. However, few studies have
looked for discontinuities (clumps of similarly sized species or gaps of sizes that contai...
