Catalogue and Systematics of Pliensbachian, Toarcian and Aalenian Radiolarian Genera and Species

This volume comprises a catalogue of 90 genera, 274 species and 13 subspecies of Pliensbachian, Toarcian and Aalenian Radiolaria. Two genera, 37 species and 3 subspecies are new formal descriptions, 24 species are described in open nomenclature. Each taxon is presented with a complete and up-to-date synonymy, original description and original remarks (translated into English where necessary), subsequent emendations, remarks by the authors of this catalogue, and etymology. Descriptions of species/subspecies further contain the original measurements, type locality, and data on geographic distribution. Plates illustrate the holotype and one or several specimens from our material, from different paleogeographic realms where possible. The material was collected from 30 measured sections in the Circum-Pacific belt (Baja California Peninsula, Oregon, British Columbia, Japan) and the Tethyan realm (Oman, Turkey, Slovenia, Austria). Abbreviated locality information and a list of all treated taxa are given in the last two chapters.A useful book for paleontologists interested in taxonomy of Jurassic radiolarians.Katalog obsega 90 rodov, 274 vrst in 13 podvrst radiolarijev iz treh stopenj v spodnji in srednji juri: pliensbachija, toarcija in aalenija. Dva rodova, 37 vrst in 3 podvrste so formalno opisani novi taksoni, 24 vrst je opisanih v odprti nomenklaturi. Vsak takson je predstavljen z vso dosedanjo sinonimiko, originalnim opisom in originalnimi opombami (v prevodu, če originalni jezik ni angleščina), poznejšimi revizijami, pripombami avtorjev tega kataloga in etimologijo. Opisi vrst in podvrst vsebujejo še originalne meritve, ime tipične lokalitete in podatke o geografski razširjenosti. Vsaka vrsta ali podvrsta je predstavljena s samostojno tablo, na kateri so slike holotipa in več primerkov iz naših vzorcev. Kjer je mogoče, so ilustrirani primerki z različnih paleogeografskih območij. Vzorci so bili pobrani na 30 profilih, posnetih v cirkumpacifiškem pasu (Kalifornijski polotok, Oregon, Britanska Kolumbija, Japonska) in v območju Tetide (Oman, Turčija, Slovenija, Avstrija). Dodatek na koncu knjige vsebuje kratek opis vzorčevanih profilov in seznam vseh obravnavanih taksonov

Origin and diversification of dung beetles in Madagascar

Madagascar has a rich fauna of dung beetles (Scarabaeinae and Aphodiinae) with almost 300 species described to date. Like most other taxa in Madagascar, dung beetles exhibit an exceptionally high level of endemism (96% of the species). Here,we review the current knowledge of the origin and diversification of Malagasy dung beetles. Based on molecular phylogenies, the extant dung beetles originate from eight colonizations, of which four have given rise to extensive radiations. These radiations have occurred in wet forests, while the few extant species in the less successfu lradiations occur in open and semi-open habitats. We discuss the likely mechanisms of speciation and the ecological characteristics of the extant communities, emphasizing the role of adaptation along environmental gradients and allopatric speciation in generating the exceptionally high beta diversity in Malagasy dung beetles. Phylogeographic analyses of selected species reveal complex patterns with evidence for genetic introgression between old taxa. The introduction of cattle to Madagascar 1500 years ago created a new abundant resource, onto which a few species have shifted and thereby been able to greatly expand their geographical ranges.Peer reviewe

The Bostrichidae of the Maltese Islands (Coleoptera)

The Bostrichidae of the Maltese Islands are reviewed. Ten species are recorded with certainty from this Archipelago, of which 6 namely, Trogoxylon impressum (Comolli, 1837), Amphicerus bimaculatus (A.G. Olivier, 1790), Heterobostrychus aequalis (Waterhouse, 1884), Sinoxylon unidentatum (Fabricius, 1801), Xyloperthella picea (A.G. Olivier, 1790) and Apate monachus Fabricius, 1775 are recorded for the first time. Two of the mentioned species (H. aequalis and S. unidentatum) are alien and recorded only on the basis of single captures and the possible establishment of these species is discussed. Earlier records of Scobicia pustulata (Fabricius, 1801) from Malta are incorrect and should be attributed to S. chevrieri (A. Villa & J.B. Villa, 1835). A zoogeographical analysis and an updated checklist of the 12 species of Bostrichidae recorded from the Maltese Islands and neighbouring Sicilian islands (Pantelleria, Linosa and Lampedusa) are also provided. Rhizopertha dominica (Fabricius, 1792) form granulipennis Lesne in Beeson & Bhatia, 1937 from Uttarakhand (northern India) was overlooked by almost all subsequent authors. Its history is summarized and the following new synonymy is established: Rhizopertha dominica (Fabricius, 1792) form granulipennis Lesne in Beeson & Bhatia, 1937 = Rhyzopertha dominica (Fabricius, 1792), syn. n. Finally, records of Amphicerus bimaculatus from Azerbaijan, of Bostrichus capucinus (Linnaeus, 1758) from Jordan and Syria, of Scobicia chevrieri from Jordan and Italy, of Xyloperthella picea from Italy, and of Apate monachus from Corsica (France) and Italy, are also provided.peer-reviewe
