The geographic distribution of the European Branchiopods (Anostraca, Notostraca, Spinicaudata, Laevicaudata)

Abstract

The 'Large Branchiopod' fauna of Europe consists of 72 species and sub-species: 50 anostracans, 8 notosnacans, 12 spinicaudatans, and 2 laevicaudatans. Their geographical distribution is mapped, and remarks on ecological requirements of species are given.

A rapid survey of large branchiopods in Romania

“…This is probably related to the landscape variability of this country (five biogeographic regions are represented), the continental precipitation patterns and the large surface of lowlands. In agreement with the literature (Botnariuc andOrghidan 1953, Brtek andThiéry 1995), our data show that the areas with the largest number of species tend to be flatlands and open areas. In more than half of the surveyed landscapes we found frequency values of large branchiopods as a group larger than 25%, suggesting a high detection probability of large branchiopod habitats.…”

“…Those species were C. carnuntanus (Banat Plain), D. hankoi, T. stagnalis (Ciuc basin), L. couesii (Lower Danube) (Table 1). T. stagnalis is a relatively widespread species in Western Europe (Brtek & Thiéry 1995), but it was found in Romania only very recently (Demeter 2004(Demeter , 2005. Some species were found to be rare on the landscape level as S. torvicornis and T. cancriformis in the Ciuc basin, but widespread on the national level based on literature data (S. torvicornis) and this study (T. cancriformis).…”

General aspects of the large branchiopod crustacean fauna of Mongolia

“…2); Lepidurus mongolicus Vekhov, 1992 (Fig. 5); and Triops numidicus (Grube, 1865) (described as Apus; ϭ Apus granarius Lucas in Simon (1886), ϭ Triops granarius (Lucas, 1886); concerning this synonymy, see Brtek and Thiéry 1995;Brtek 1997;Naganawa 2001a) (Fig. 2).…”

“…However, most common Mongolian anostracans are not localized-endemic to the region. For example, the nonchirocephalids Branchinecta orientalis and Branchipodopsis affinis were earlier described from easternmost Mongolia (Sars 1901) and later found to be more widespread (Vekhoff 1993;Brtek and Thiéry 1995;Belk and Brtek 1995).…”

pH-related Hatching Success of Triops cancriformis (Crustacea: Branchiopoda: Notostraca)

“…The tadpole shrimp Triops cancriformis (Bosc, 1801), an inhabitant of temporary freshwater pools, is widely distributed in Eurasia and North Africa (Longhurst, 1955;Zaffagnini & Trentini, 1980;Brtek & Thie´ry, 1995). The subspecies T. cancriformis cancriformis occurs in Austria primarily along the Morava and Danube rivers, and the Wiener Becken Depression as well as the National Park Neusiedler See -Seewinkel (Eder & Ho¨dl, 2003).…”
