“…The floodplain of the Medjerda river is in fact a hot-spot of large branchiopod diversity in the Mediterranean bioregion: an area of a few square kilometres between the northern shore of the Sebkha El Ariana and the mouth of the Medjerda river itself hosts 9 large branchiopod species, with large branchiopod multiple coexistence of up to 7 species at a single site. Such a high diversity is comparable to that of the Chaouia Plain in Morocco (Thiéry 1991, van den Broeck et al 2015.…”

“…In the Maghreb, Moroccan and Algerian large branchiopod faunas are relatively well-known (see Thiéry 1987, van den Broeck et al 2015, Samraoui et al 2006, and references therein), and are characterised by a high diversity and a pronounced degree of endemism. Conversely, to date an updated and comprehensive synoptic inventory of Tunisian Anostraca, Notostraca and Spinicaudata has not been compiled, and only scattered records are available for several species.…”

Abstract:Temporary ponds are the most peculiar and representative water bodies in the arid and semiarid regions of the world, where they often represent diversity hotspots that greatly contribute to the regional biodiversity. Being indissolubly linked to these ecosystems, the so-called "large branchiopods" are unanimously considered flagship taxa of these habitats. Nonetheless, updated and detailed information on large branchiopod faunas is still missing in many countries or regions. Based on an extensive bibliographical review and field samplings, we provide an updated and commented checklist of large branchiopods in Tunisia, one of the less investigated countries of the Maghreb as far as inland water crustaceans are concerned. We carried out a field survey from 2004 to 2012, thereby collecting 262 crustacean samples from a total of 177 temporary water bodies scattered throughout the country. Large branchiopod crustaceans were observed in 61% of the sampled sites, leading to the identification of fifteen species. Among these, the halophilic anostracan Branchinectella media is here reported for the first time for the country; conversely, four eScholarship provides open access, scholarly publishing services to the University of California and delivers a dynamic research platform to scholars worldwide. of the species reported in literature were not found during the present survey. Based on literature and novel data, the known large branchiopod fauna of Tunisia now includes 19 species, showing a noteworthy species richness when the limited extension of the country is considered. For each species, the regional distribution is described and an annotated list of references is provided. Under a conservation perspective, the particular importance of the temporary ponds occurring in the Medjerda river alluvial plain is further stressed. In this location, several large branchiopod taxa with different ecological requirements converge and form unique and species-rich assemblages that should be preserved.

The higher Fager's index values for combinations involving one Table III. notostracan and one anostracan species were comparable with values detected in Moroccan ponds (Van Den Broeck et al 2015). The long hydroperiod and the large surface area of the Sandonaci floodplain (pond codes PU001-4) probably promoted the rare conditions that allowed the alternation of different large branchiopods assemblages in the same site (up to six syntopic species).…”

Diversity and distribution of large branchiopods (Branchiopoda: Anostraca, Notostraca, Spinicaudata) in Apulian ponds (SE Italy)

A first extensive survey in the inland waters of Apulia was carried out with the aim to detect occurrences of large branchiopods and to assess their diversity and distribution in the region. Samples were gathered during each wet season between 2004 and 2016, in several cases with multiple collections per site in different years. A total of 240 water bodies were studied. Based on a careful review of the available literature data and the results of this survey, 10 large branchiopod species (six Anostraca, two Notostraca, two Spinicaudata) are reported to occur in the Apulian inland waters at present. The findings of the spinicaudatans Leptestheria mayeti and Cyzicus tetracerus and of the anostracan Streptocephalus torvicornis are new records for the Italian mainland. Different species assemblages were found to correspond to specific sets of environmental conditions and habitat types. The diversity of large branchiopods in the region indicates the distinctive role of the Apulian inland waters and their ecological importance in the biogeography of the crustacean inland water fauna in the Mediterranean area. The conservation status of the environments where the species were collected is also discussed.

“…Although large branchiopods have a worldwide distribution, their diversity patterns, distribution and conservation status are poorly known, especially for large parts of Africa (Brendonck et al, 2008). Distribution and ecology of North African large branchiopods are currently best known from Morocco (Thiéry, 1987;Roux & Thiéry, 1988, van den Broeck et al, 2015, and references therein), and Algeria (Gauthier, 1928a, b;Samraoui & Dumont, 2002;Samraoui et al, 2006). Conversely, after the seminal contributes of Gurney (1909) and Gauthier (1928a, b), and some further data recently published (e.g.…”

The role of spatial environmental factors as determinants of large branchiopod distribution in Tunisian temporary ponds

et al. 2016

View full text Add to dashboard Cite

The influence of spatial and environmental factors in explaining the structure of large branchiopod assemblages at different spatial scales is still poorly explored. We hypothesized that the extent of actual spatial connectivity, and thus the spatial distribution of a metacommunity, may depend on the environmental conditions as represented by climatic gradients and the structural characteristics of the landscape. To test this hypothesis, the distributional patterns of 14 large branchiopod species in a set of 177 temporary water bodies repeatedly sampled across Tunisia and on its main islands were analysed. Physical, chemical, morphological and climatic characteristics of the studied water bodies were collected as well, and spatial structures were described using distance-based Moran’s Eigenvector Maps. Distance-based Redundancy Analysis and variance partitioning explained more than one-half of total variation. Mantel’s autocorrelograms demonstrated that species composition was spatially autocorrelated at shorter distances in the Mediterranean part of the country than in the southern, more arid part. These results suggest that both dispersal limitation and species response to spatially structured environmental gradients might be involved in determining large branchiopod distribution in Tunisia and that these patterns may greatly vary on a regional basis
