Zooplankton (Cladocera) species turnover and long-term decline of Daphnia in two high mountain lakes in the Austrian Alps
We investigated long-term succession of sedimentary cladoceran assemblages in two morphologically divergent mountain lakes by utilizing sediment traps and previously available sediment data. We aimedExpand

The jellification of north temperate lakes
Calcium (Ca) concentrations are decreasing in softwater lakes across eastern North America and western Europe. Using long-term contemporary and palaeo-environmental field data, we show that this isExpand

A review on utilizing Bosmina size structure archived in lake sediments to infer historic shifts in predation regimes
Zooplankton are considered excellent indicators of aquatic food web structure, due to their role as grazers on primary producers and their sensitivity to predation by both planktivorous fish andExpand

A comparison of pre-industrial and present-day changes in Bosmina and Daphnia size structure from soft-water ontario lakes.
Understanding the long-term controls on cladoceran size structure has important implications for aquatic ecosystems. Although there has been considerable interest in zooplankton size trends forExpand

Establishing past environmental conditions and tracking long-term environmental change in the Canadian Maritime provinces using lake sediments
Freshwater lakes in the Canadian Maritime provinces have been detrimentally influenced by multiple, often synergistic, anthropogenically-sourced environmental stressors. These include surface-waterExpand

Examining the effects of climate change, acidic deposition, and copper sulphate poisoning on long-term changes in cladoceran assemblages
We analyzed cladoceran remains in dated sediment cores from four lakes in Nova Scotia, Canada, to assess the potential effects of climate warming, acidic deposition, and a major fish kill caused byExpand

Assessing environmental stressors on a commercial walleye fishery from a large northern ecosystem (Tathlina Lake) using water chemistry and paleolimnology
Abstract Tathlina Lake (Northwest Territories, Canada) is a large, shallow ecosystem in the rapidly warming northern boreal forest. This lake is of considerable cultural and economic significance asExpand

Establishing reliable minimum count sizes for cladoceran subfossils sampled from lake sediments
The effects of low counts on assemblage inferences in paleolimnological investigations have been examined for many biological proxies, but not yet for Cladocera. Established guidelines leading to theExpand

An illustrated guide to the identification of cladoceran subfossils from lake sediments in northeastern North America: part 1—the Daphniidae, Leptodoridae, Bosminidae, Polyphemidae, Holopedidae,
Cladocera identifications based on subfossil remains differ considerably from identifications based on whole animals, yet despite this very few subfossil Cladocera identification guides exist. InExpand

An illustrated guide to the identification of cladoceran subfossils from lake sediments in northeastern North America: part 2—the Chydoridae
The diverse members of the cladoceran family Chydoridae are typically well preserved in lake sediments, although identifications of chydorids using subfossil remains still differ from identificationsExpand
