Cím:Centres of endemism of Noctuidae (Lepidoptera) in the Palaearctic high mountains / Zoltán Varga
Dátum:2009
Megjegyzések:In the Palaearctic two types of oreal fauna co-exist. The alpine type of the humid orobiomes shows strong connections to the tundral zonobiome. Oppositely, the xeromontane faunal type of arid orobiomes shows connections to deserts and grasslands of the eremic zonobiome. The alpine type is influenced by the Quaternary glaciations, resulting in long-distance area disjunctions (arctic-alpine species). The xeromontane faunal type typifies the summer-dry Mediterranean mountains and the arid mountains of Central Asia. High potential of speciation was observed in taxonomic groups adapted to cold-arid conditions (e.g. rodents, cutworm Noctuidae, Orthoptera). The members of the xeromontane fauna often have endemic/disjunct areas. Basic faunal structures were recognised by accumulated occurrence of endemic species and by high species-diversity of some typical genera. The restricted areas of allopatric sisterspecies fulfill the criteria of the "areas of endemism". Core areas indicated by the accumulation of endemic species can be supported by the allopatric subspecies of polytypic species and by allopatric sibling species of superspecies. Noctuinae genera with "cutworm larvae originated in the continental orobiomes (e.g. Euxoa, Dichagyris, Chersotis, Rhyacia). Other genera are connected with xerophytic scrub formations (Auchmis, Lophoterges, Copiphana). Their Mediterranean-Anatolian taxa often show Western and Central Asiatic connections. Other genera evolved under the influence of the young Tertiary aridisation of the Mediterranean basin. The south-eastern Palearctic orobiomes are the most important core areas of many relict genera (Erebophasma, Palaeamathes, Hoeneidia, Hadulipolia, Niaboma, etc.) and ancestral species from widely distributed genera. They have connections to the highmountains of Central Asia and Southern Siberia and also to the continental steppe areas. The stenochorous, ancestral taxa are regularly connected to the monsoonic forested biomes, while the derived species or species groups are inhabitants of the at least seasonally dry orobiomes, or they are zonally distributed in the boreal coniferous forests of the Palearctic/Holarctic).
