TLDR
The present study employed allozymic and morphological analyses to ascertain the taxonomic status of six species in the genus Bosmina from North America.Abstract:
Prior morphological studies have led to the recognition of six species in the genus Bosmina from North America. The present study employed allozymic and morphological analyses to ascertain the taxo...read more

Facilitative interactions among aquatic invaders: is an "invasional meltdown" occurring in the Great Lakes?
TL;DR: A widely cited hypothesis in ecology is that species-rich communities are less vulnerable to invasion than species-poor ones, owing to competition for limiting resources (the "biotic resistance" hypothesis).

Cladocera and Other Branchiopod Crustaceans
Atte Korhola,Milla Rautio +1 more
TL;DR: Lake sediments contain a variety of organic and inorganic remains that may be used to track the history of a lake or its catchment, and many contradictory records and opinions have been presented concerning their paleoecology and indicator value of cladocerans.
Journal ArticleDOI
Functional diversity of crustacean zooplankton communities: towards a trait‐based classification
TL;DR: A regional community dendrogram for common north-eastern North American zooplankton species was generated and shows that taxonomic differences between species do not capture fully functional differences based on the traits of body length, habitat, trophic group and feeding type.

Ballast-mediated animal introductions in the Laurentian Great Lakes: retrospective and prospective analyses
Igor A. Grigorovich,Robert I. Colautti,Edward L. Mills,Kristen T. Holeck,Albert G. Ballert,Hugh J. MacIsaac +5 more
TL;DR: In this article, the authors integrated knowledge of species' invasion histories, shipping traffic patterns, and physicochemical factors that constrain species' survivorship during ballast-mediated transfer to assess the risk of future introductions to the Great Lakes.
Journal ArticleDOI
Effects of an invasive bivalve on the zooplankton community of the Hudson River
TL;DR: This study used intervention time series analysis of abundance, biomass and reproduction over the period 1987–95 to assess changes in zooplankton in response to the invasion of zebra mussels.

A revision of the Australian Cladocera (Crustacea)
N. N. Smirnov,Brian V. Timms +1 more
TL;DR: The cladoceran fauna of Australia, besides including many cosmopolitan and pantropical forms, also has some species widely distributed in the Holarctic, some Gondwanaland species, and a large number of endemics.

The taxonomy and biogeography of the Cladocera
TL;DR: It is concluded overwhelmingly that the chydorid Cladocera are not cosmopolitan in distribution but instead are restricted to smaller regions by their specific ecological requirements for habitat type and also by long-term events in earth history.

Polyphyletic origins of asexuality in daphnia pulex. i. breeding-system variation and levels of clonal diversity.
TL;DR: This paper examined the genotypic structure of Daphnia pulex populations from a region in which there is an abrupt microgeographical shift in breeding system and found that the shift to asexuality has been linked to sex-limited meiosis suppression.
Journal ArticleDOI
The Cladocera of Ontario with remarks on some species and distribution
TL;DR: The Cladocera of Ontario were studied from material collected over a wide geographical area and based on a study of this material Daphnia pulicaria Forbes is raised from synonymy in the North American fauna.
Journal ArticleDOI
The Divergence of Adjacent Populations
TL;DR: In Union Bay, a temperate embayment in Seattle, Washington, USA two different kinds of predators maintain a polymorphism of the cladoceran Bosmina longirostris, setting up a spatial situation in which adjacent populations of BosminA actually diverge phenotypically and genetically during the summer.
