On Recent species of Tonnacypris Diebel & Pietrzeniuk, 1975 (Crustacea, Ostracoda), with new species descriptions from Mongolia (2009)

Van Der Meeren, Thijs, Khand, Yondon, Martens, Koenraad

The ostracod species Tonnacypris estonica (Järvekülg, 1960), T. tonnensis (Diebel & Pietrzeniuk, 1975), T. edlundi n. sp. and T. mazepovae n. sp. are here reported from Mongolia. Redescriptions of...

Global diversity of ostracods (Ostracoda, Crustacea) in freshwater (2008)

Martens, Koenraad, Schon, Isa, Meisch, Claude, Horne, David J.

There are close to 2,000 subjective species and about 200 genera of Recent non-marine Ostracoda. Together, Cyprididae (1,000 spp.) and Candonidae (c. 550 spp.) represent more than 75% of the extant...

The freshwater animal diversity assessment: An overview of the results (2008)

Balian, E. V., Segers, H., Leveque, C., Martens, Koenraad

We present a summary of the results included in the different treatments in this volume. The diversity and distribution of vertebrates, insects, crustaceans, molluscs and a suite of minor phyla is...

Martens, Koenraad

The present paper describes Mnementh brennei n. sp. n. gen., a new non-marine ostracod species and genus from temporary wetlands in the Western Cape Province (South Africa). The new genus is the...

Water quality and diversity of the Recent ostracod fauna in lowland springs from Lombardy (northern Italy) (2007)

Pieri, Valentina, Caserini, Claudia, Gomarasca, Stefano, Martens, Koenraad, Rossetti, Giampaolo

The Po river plain (northern Italy) is delimited to two mountain ridges, the Alps and the Apennines. It hosts peculiar lowland man-modified springs, locally known as "fontanili", which originate from...

Early release of eggs and embryos in a brooding ancient asexual ostracod: brood selection or a gambling strategy to increase fecundity? (2007)

Pinto, Ricardo L., Rocha, Carlos E.F., Martens, Koenraad

Asexual lineages lack the means to purge their genomes of (deleterious) mutations through recombination. Evolutionary theory thus predicts that such lineages will be prone to early extinction. In...

Matzke-Karasz, Renate, Martens, Koenraad

Afrocypris barnardi G. O. Sars, 1924, a giant temporary pool ostracode from South Africa, is here redescribed, based on new material. It is only the second time that this species has been found. The...
