DNA taxonomy of the potamid freshwater crabs from Northern Africa (Decapoda, Potamidae)

2020

The Mediterranean area, from southern Balkans to western Maghreb, is inhabited by the Potamon subgenus Euthelphusa, with three currently recognised species. The Maghrebian species P. (E.) algeriense is isolated from other Potamon species by the Mediterranean Sea and the Sahara Desert, and nearly no molecular data are currently available for this taxon. Present study investigated the mtDNA and nuDNA diversity in Potamon algeriense s.l. with the aims of exploring its molecular diversity pattern throughout its known distribution range, and testing the possible presence of cryptic taxa currently lumped under this binomen. The phylogenetic and DNA taxonomy analyses showed the presence of two wel…

Do distantly related parasites rely on the same proximate factors to alter the behaviour of their hosts?

2006

Phylogenetically unrelated parasites often increase the chances of their transmission by inducing similar phenotypic changes in their hosts. However, it is not known whether these convergent strategies rely on the same biochemical precursors. In this paper, we explored such aspects by studying two gammarid species ( Gammarus insensibilis and Gammarus pulex ; Crustacea: Amphipoda: Gammaridae) serving as intermediate hosts in the life cycle of two distantly related parasites: the trematode, Microphallus papillorobustus and the acanthocephalan, Polymorphus minutus . Both these parasite species are known to manipulate the behaviour of their amphipod hosts, bringing them towards the water surfa…

Kali dodecanesicum (Chenopodiaceae, Salsoloideae) a new species from Greece

2015

Kali dodecanesicum, a new species from some islands (i.e. Rhodes, Kos and Nisyros) of the Dodecanese in the south-eastern Aegean (Greece), is described and illustrated. According to recent literature, Kali is treated as a distinct genus from the polyphyletic Salsola s.l., which includes several annual species. The new species is morphologically well separated from the other Kali taxa mainly for the shape of the fruiting perianth, showing closer relationships with Kali ponticum. Its ecological requirements, distribution, and conservation status are also examined, together with an analytic key of the Kali species occurring in the Mediterranean area.

A new species of Kali (Salsoloideae, Chenopodiaceae) from Sicily, supported by molecular analysis

2015

Nomenclatural and taxonomical considerations on Kali , a controversial genus recently segregated from the polyphyletic Salsola s. lat. ( Chenopodiaceae ), are provided. The Kali group includes annual plants with leaves ending in a spine and lacking hypodermis, having also a cortex alternate to longitudinal chlorenchymatous striae. The species belonging to this genus mainly have a paleotemperate distribution (Europe, Asia and North Africa), occurring as aliens in North America, Australia and South Africa. A new species collected on Mt. Etna (Sicily), and closely related to K. australe , is described and illustrated as K. basalticum Its morphological and molecular features, karyology (2n=54),…

First Report of Agaricus aridicola in Saudi Arabia and Ecological Notes on Agaricus bisporus

2015

Agaricus aridicola is reported for the first time from Saudi Arabia while Agaricus bisporus is a new record for Northern region of Saudi Arabia. This study includes notes on taxonomy, ecology and distribution of both the species. It was also reported that the habitat of A. aridicola and A. bisporus are characterized by calcareous sandy soil, poor in organic matter, with presence of little amount of salinity.

The genus Bolbelasmus in the western and southern regions of the Mediterranean Basin (Coleoptera: Geotrupidae: Bolboceratinae)

2016

The Bolbelasmus Boucomont, 1911 species of the western and southern regions of the Mediterranean Basin (Northern Africa, Iberian Peninsula and France) are revised. The following three new species are described: Bolbelasmus brancoi Hillert & Král sp. nov. and Bolbelasmus howdeni Hillert & Král sp. nov., both from Spain and Gibraltar, and Bolbelasmus nikolajevi Hillert, Arnone, Král & Massa sp. nov. from Egypt, Libya and Tunisia. Bolbelasmus vaulogeri (Abeille de Perrin, 1898) stat. restit. is removed from synonymy with B. bocchus (Erichson, 1841) and reinstated as a separate species. Bolbelasmus romanorum Arnone & Massa, 2010 is considered a junior subjective synonym of B. vaulogeri. Lectoty…
