Mitochondrial DNA Regionalism and Historical Demography in the Extant Populations of Chirocephalus kerkyrensis (Branchiopoda: Anostraca)
2012
BackgroundMediterranean temporary water bodies are important reservoirs of biodiversity and host a unique assemblage of diapausing aquatic invertebrates. These environments are currently vanishing because of increasing human pressure. Chirocephalus kerkyrensis is a fairy shrimp typical of temporary water bodies in Mediterranean plain forests and has undergone a substantial decline in number of populations in recent years due to habitat loss. We assessed patterns of genetic connectivity and phylogeographic history in the seven extant populations of the species from Albania, Corfu Is. (Greece), Southern and Central Italy.Methodology/principal findingsWe analyzed sequence variation at two mito…
Chirocephalus sarpedonis sp. nov. (Branchiopoda, Anostraca, Chirocephalidae) from Turkey questions the monophyly of the traditional Chirocephalus spe…
2017
Chirocephalus sarpedonis sp. nov. (Anostraca, Chirocephalidae), collected in a temporary pond in Lycia (Turkey), is described and its affinities with the other species of the genus are investigated based on both morphology and mtDNA cytochrome oxidase subunit I (COI) sequences. Male and female morphology suggests its major affinity with the species belonging to the bairdi-group although the morphological peculiarities of the species make it difficult to ascribe C. sarpedonis sp. nov. to any of the Chirocephalus species-groups which are currently used in the systematics of the genus. Furthermore, molecular analyses based on the comparison with available Chirocephalus spp. COI sequences fail …
Molecular and morphological data suggest weak phylogeographic structure in the fairy shrimp Streptocephalus torvicornis (Branchiopoda, Anostraca)
2017
Inland aquatic organisms almost ubiquitously display a pattern of marked provincialism characterized by substantial population differentiation and genealogical discontinuities. This is the result of strong priority effects and local adaptation following dispersal and colonization of new habitats. We present a case that defies this biogeographic paradigm. We have investigated the phylogeography of the fairy shrimp Streptocephalus torvicornis across its circum-Mediterranean and Eurasian distribution. Based on three independent datasets, namely sequence variation at 12S and 16S rRNA, cyst morphology and male second antenna characters, we discern a pattern of extensive genetic and morphological…
Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Crustacea, Branchiopoda, Anostraca): On the verge of extinction?
2016
The province of Cadiz (South of Spain) hosts the only known locality in the world of Linderiella baetica Alonso & Garcia-de-Lomas 2009 (Anostraca). In this paper, the geographical distribution of the species based on published sampling data focused on large branchiopods and temporary pools in Andalusia and the entire Iberian Peninsula is assessed. The current situation is summarized based on the threats to their survival, which are mainly related to habitat alteration. In the Iberian Peninsula, at least 1,648 bodies of water (about 720 in Andalusia) have been explored. Prevalence data suggest that L. baetica is a rare species (localities with presence / sample locations = 6.07 . 10-4). The …
