Global diversity of rotifers (Rotifera) in freshwater
TLDR
Rotifera is a Phylum of primary freshwater Metazoa containing two major groups: the heterogonic Monogononta and the exclusively parthenogenetic Bdelloidea.Abstract:
Rotifera is a Phylum of primary freshwater Metazoa containing two major groups: the heterogonic Monogononta and the exclusively parthenogenetic Bdelloidea. Monogononta contains 1,570 species-level taxa, of which a majority (1,488) are free-living fresh or inland water taxa. Bdelloidea contains 461 “species,” only one of which is marine, but with many limnoterrestrial representatives or animals of unknown ecology. Actual numbers may be much higher, considering the occurrence of cryptic speciation in Monogononta and the unsatisfactory nature of taxonomic knowledge. Rotifers, mostly monogononts, occur in all types of water bodies, worldwide. They are particularly diverse in the littoral zone of stagnant waterbodies with soft, slightly acidic water and under oligo- to mesotrophic conditions. The rotifer record is highest in the Northern hemisphere, which may be due to the concentration of studies in those regions. Diversity is highest in the (sub)tropics; hotspots are northeast North America, tropical South America, Southeast Asia, Australia, and Lake Baikal, endemicity is low in Africa (including Madagascar), Europe, the Indian subcontinent, and Antarctica. Although the lack of fossil evidence and of molecular phylogenetic studies are major hindrances, contrasting hypotheses on the origin and evolutionary history of Brachionus, Macrochaetus, and Trichocerca are presented.read more

The Freshwater Animal Diversity Assessment: an overview of the results
TL;DR: The diversity and distribution of vertebrates, insects, crustaceans, molluscs and a suite of minor phyla is compared and commented upon and it is shown that data are deficient for many other groups.

Implications of differences between temperate and tropical freshwater ecosystems for the ecological risk assessment of pesticides
TL;DR: Pesticide dissipation rates and vulnerability of freshwaters appear not to be consistently higher or lower in tropical regions compared to their temperate counterparts, however, differences in fate and effects may occur for individual pesticides and taxa.

Patterns of diversity in soft-bodied meiofauna: dispersal ability and body size matter
Marco Curini-Galletti,Tom Artois,Valentina Delogu,Willem H. De Smet,Diego Fontaneto,Diego Fontaneto,Ulf Jondelius,Francesca Leasi,Alejandro Martínez,Inga Meyer-Wachsmuth,Karin Sara Nilsson,Paolo Tongiorgi,Katrine Worsaae,M. Antonio Todaro +13 more
TL;DR: The macroecological analysis of meiofauna indicates that not only body size but mostly dispersal ability and also occurrence in the endobenthic habitat are important correlates of diversity for these understudied animals, with different importance at different spatial scales.

TL;DR: In this paper, the authors provide a baseline synthesis of the terrestrial and freshwater invertebrate fauna of the Barents Sea archipelagoes, highlight the taxa present, the characteristic elements of fauna and the complexity of their biogeography.

Freshwater biodiversity in the rivers of the Mediterranean Basin

TL;DR: A comparison of the ecological and biological traits of endemic and non-endemic species of three riverine groups revealed that endemic species have several strategies and mechanisms to face typical mediterranean-climate conditions, such as drought, when compared to non- endemic species.

The Unified Neutral Theory of Biodiversity and Biogeography
TL;DR: A study of the issue indicates that it is not a serious problem for neutral theory, and there is sometimes a difference between some of the simulation-based results of Hubbell and the analytical results of Volkov et al. (2003).
Journal ArticleDOI
The Monopolization Hypothesis and the dispersal–gene flow paradox in aquatic organisms
TL;DR: It is argued that founder events combined with rapid local adaptation may underlie the striking patterns of genetic differentiation for neutral markers in many aquatic organisms, and patterns of regional genetic differentiation may often reflect historical colonization of new habitats rather than contemporary gene flow.

The Ubiquity of Small Species: Patterns of Local and Global Diversity
Tom Fenchel,Bland J. Finlay +1 more
TL;DR: For small organisms, the relationship between species and area is flat, and a latitudinal diversity gradient is absent or weak, and these patterns are explained by some of the assumptions underlying the unified neutral community model.

TL;DR: The early Cretaceous is one of three large continental blocks with large contiguous land areas surrounded by shallow epicontinental waters at high sea-level stands as discussed by the authors, and there were no deep-water passages to the Arctic.
