“…This difference had previously been observed in a survey within T. cancriformis populations (sensu Korn et al, 2006), where a very low level of variability was found for the 12S and 16S genes . The same paper demonstrated also that T. cancriformis was significantly differentiated from a selection of congeneric taxa, thus supporting the hypothesis that this species should be ascribed to a separated genus (Linder, 1952).…”

Mitochondrial and nuclear DNA variability in the living fossil Triops cancriformis (Bosc, 1801) (Crustacea, Branchiopoda, Notostraca)

The living fossil Triops cancriformis comprises bisexual (either gonochoric or hermaphroditic) and unisexual populations. Genetic surveys have recently revealed a general trend of low differentiation of 12S and 16S mitochondrial genes. We, therefore, surveyed further mitochondrial (COI gene and control region) and nuclear markers (dinucleotide microsatellites) to assess the genetic variability and to establish any relationship with the different reproductive modes found in European populations. The mitochondrial analyses confirmed the pattern of low variability. Hence, the low mitochondrial genetic variability appears as a common feature of the genus Triops. The microsatellite analysis found that Italian populations are monomorphic or exhibit little polymorphism, while other European samples display a higher degree of polymorphism and private alleles. Spanish, Austrian and Italian populations show patterns of Hardy-Weinberg disequilibrium that could be explained by the mode of reproduction, or by a higher frequency of null alleles in these populations. The low diversity and differentiation among Italian populations lead us to question the Monopolization Hypothesis. One microsatellite locus appears to be sex-linked, with heterozygotes detected only in males and hermaphrodites.

“…Linder (1941) questioned that the female and male specimens described by Gurney (1909) did in fact belong to the same species, and suggested that the presumptive S. bimaris females could actually have been immature Chirocephalus specimens. Conversely, according to Belk and Brtek (1995), S. bimaris might be a senior synonym of the Ethiopian species Streptocephalus chappuisi Brehm, 1935.…”

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.

“…Adolpho Lutz, otherwise, registered the occurrence in Macaiba, Rio Grande do Norte-RN, in 1929, from the species Dendrocephalus ornatus, by its bright scarlet color. Linder (1941), in turn, verified that the species described by Lutz (1929) was actually Dendrocephalus brasiliensis that Pesta wrote about in 1921.…”
