![]() The role these organisms play in the life history of the sponge is unclear although some bacteria are certainly symbiotic. It is in the endosome that some sponges also harbour vast numbers of other organisms, particularly bacteria, including cyanobacteria, and microalgae. They have two distinct layers, the outer ectosome and the inner endosome. Sponges provide an ideal habitat for microorganisms including cyanobacteria. These studies have provided abundant sequence data to the 16S rRNA gene together with phylogenetic analysis, thus providing good material for future comparisons. įor a number of years cyanobacteria have been the focus of intense molecular studies in the hopes of determining the origins of the higher plant plastid. In this situation, where a large number of species occur and many species are unculturable, phylogenetic analysis of sequence data from the 16S ribosomal RNA (rRNA) gene provides a powerful tool for the classification of microbes including cyanobacteria. Marine sponges contain a complex mixture of bacteria (both symbiotic and incidental), fungi, unicellular algae and cyanobacteria (also both symbiotic and incidental).

The evolutionary history of the relict scorpion family Iuridae of the eastern Mediterranean. Parmakelis A, Dimitriadou D, Gkigkiza E, Karampatsou L, Stathi I, Fet V, et al. The genus Neocalchas emerges as one of the most ancient scorpion clades, with divergence time about 27 mya. Based on our findings, three new genera of Iurinae ( Metaiurus, Anatoliurus, and Letoiurus) are established. Both subfamilies are largely confined to the Anatolian peninsula and its few coastal islands only the most derived genus Iurus has dispersed westward to Crete and Peloponnese. Ancient patterns of isolation and dispersal are revealed. The multi-locus phylogeny clearly confirms an ancient division into two clades, Calchinae and Iurinae. Divergence time-estimate analyses, species delimitation approaches and estimation of ancestral areas were implemented in order to: (1) reconstruct the phylogenetic relationships of the Iuridae taxa, (2) evaluate the morphological classifications, and (3) obtain insights into the biogeographic history of the family in the East Mediterranean. Sequence data from three molecular markers (COX1, 16S rDNA, ITS1) originating from numerous Iuridae taxa were analyzed within a phylogenetic framework. The latest taxonomic review, based on morphological and anatomical features, raised the number of Iuridae genera to four, and the number of species to 14. Several taxonomic revisions have been conducted on this family that initially comprised two genera. Iuridae taxa are mainly found in Turkey and Greece, whereas a single species is found in northern Iraq. Iuridae is a family of scorpions that exhibits a highly complex biogeographic and taxonomic history. stathiae (Soleglad, Fet, Kovarik & Yagmur, 2012) (Greece: Karpathos Island). kadleci (Kovarik, Fet, Soleglad & Yagmur, 2010) (Turkey: Antalya and Mersin Provinces).

The subfamily Calchinae Birula, 1917 is raised from synonymy with Iurinae Thorell, 1876. There have been some studies of this family in the recent years, but in a recent article Aristeidis Parmakelis and co-workers have conducted a phylogenetic analysis of the family and based on this suggested several taxonomic decisisons. The family Iuridae are mainly found in Turkey and Greece and contains some of the largest scorpions in Europe. ![]()
