Extrinsic and intrinsic controls of zooplankton diversity in lakes.
Pelagic crustacean zooplankton were collected from 336 Norwegian lakes covering a wide range of latitude, altitude, lake area, mean depth, production (as chlorophyll a), and fish community structure.Expand
Major contribution from littoral crustaceans to zooplankton species richness in lakes
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. VeryExpand
Energy input and zooplankton species richness
What are the relative contribution of temperature and solar irradiance as types of energy deliveries for species richness at the ecosystem level? In order to reveal this question in lake ecosystems,Expand
The ecological niches of Bythotrephes and Leptodora: lessons for predicting long-term effects of invasion
We here exploit two large datasets on zooplankton in Norwegian lakes, spanning a wide range of geographical, physical, chemical and biological properties, to assess the ecological niches and habitatsExpand
The rarity concept and the commonness of rarity in freshwater zooplankton
Summary 1. Regional distribution, frequency of occurrence and relative abundance were scored in 2467 Norwegian lakes for all the recorded 130 species of crustacean zooplankton. The majority ofExpand
Littoral microcrustaceans (Cladocera and Copepoda) as indices of recovery of a limed water system
A 7 year study (1992–1998) of littoral microcrustaceans (Cladocera and Copepoda) in the watercourse of the River Rore, South Norway, illustrates that qualitative data on cladocerans and copepods areExpand
Littoral Microcrustacean (Cladocera and Copepoda) Indicators of Acidification in Canadian Shield Lakes
Abstract We identify littoral microcrustacean indicators of acidification in 2 surveys of Canadian Shield lakes conducted 10 years apart. We found a total of 90 cladoceran and copepod species withExpand
Interactions between demography and environmental effects are important determinants of population dynamics
Warmer winters alter the dynamics of a local bird population and reduce immigration rate due to density-dependent feedback. Climate change will affect the population dynamics of many species, yet theExpand
Littoral Microcrustacean (Cladocera and Copepoda) Indicators of Acidification in Canadian Shield Lakes
Abstract We identify littoral microcrustacean indicators of acidification in 2 surveys of Canadian Shield lakes conducted 10 years apart. We found a total of 90 cladoceran and copepod species withExpand
Crustacean Communities in Canada and Norway: Comparison of Species along A pH Gradient
Increased pH in acid lakes changes the crustacean fauna from communities dominated by acid-tolerant species to communities dominated by more acid-sensitive species. Studies from Canada (Killarney)Expand
