Dung beetle assemblages were monitored by monthly dung-baited pitfall trapping from July to October at Þve sites in the Southern Alps (Verdon Valley). The sites were characterized by both elevation (10aAphodiinae10abioclimatic transition10aCoprinae10aEuropean mountain10aScarabaeoidea1 aErrouissi, Faiek1 aJay-Robert, Pierre1 aLumaret, Jean-Pierre1 aPiau, Olivier  uhttps://scarabnet.myspecies.info/composition-and-structure-dung-beetle-coleoptera-aphodiidae-geotrupidae-scarabaeidae-assemblages-mou02623nas a2200229   4500008004100000245016100041210006900202300001200271490000600283520177100289653000802060653001702068653003202085653002502117653001802142653001702160653001002177100002002187700002502207700002302232856013802255       2001                        eng d00aDiversity, distinctiveness and conservation status of the Mediterranean coastal dung beetle assemblage in the Regional Natural Park of the Camargue (France)0 aDiversity distinctiveness and conservation status of the Mediter  a257-2700 v73 aThe Mediterranean region as a whole has the highest dung beetle species richness within Europe. Natural coastal habitats in this region are among those which have suffered severe human disturbance. We studied dung beetle divers- ity and distinctiveness within one of the most important coastal protected areas in the west Euro- Mediterranean region (the regional Park of Camargue, southern France) and made comparisons of dung beetle assemblages with other nearby Mediterra- nean localities, as well as with other coastal pro- tected area (Doñana National Park, Spain). Our finding showed that: (1) The species richness of coastal habitats in the Camargue is low and only grasslands showed a similar level of species rich- ness and abundance to inland habitats of other Mediterranean localities. The unique habitats of the coastal area (beaches, dunes and marshes) are largely colonized by species widely distributed in the hinterland. (2) In spite of their low general distinctiveness, dune and marsh edges are charac- terized by the occurrence of two rare, vulnerable, specialized and large roller dung beetle species of the genus Scarabaeus. As with other Mediterranean localities, current findings suggest a recent decline of Scarabaeus  populations and the general loss of coastal dung beetle communities in Camargue. (3) The comparison of dung beetle assemblages between the Camargue and Doñana shows that, in spite of the low local dung beetle species rich- ness in the Camargue, the regional dung beetle diversity is similar between both protected areas. Unique historical and geographical factors can explain the convergence in regional diversity as well as the striking divergence in the composition of dung beetle assemblages between both territories.10aDon10aDung beetles10ainsect coastal conservation10aMediterranean region10aScarabaeoidea10athe Camargue10ãana1 aLobo, Jorge, M.1 aLumaret, Jean-Pierre1 aJay-Robert, Pierre  uhttps://scarabnet.myspecies.info/diversity-distinctiveness-and-conservation-status-mediterranean-coastal-dung-beetle-assemblage-regio01221nas a2200205   4500008004100000245011300041210006900154300001200223490000600235520046200241653002400703653001500727653001700742653003500759653002500794653001800819100002500837700002000862856013300882       1996                        eng d00aGeographic distribution of endemic dung beetles (Coleoptera, Scarabaeoidea) in the Western Palaeartic region0 aGeographic distribution of endemic dung beetles Coleoptera Scara  a192-1990 v33 aThe distribution of endemic dung beetle species has been analysed in the West Palaearctic region (547spp.). These species are concentrated in the Mediterranean Basin or in the neighbouring regions, with two main centres of endemism located on opposite sides of thls Basin. The centres of endemism and the degree of endemicity were very different according to the three main dung beetle families. The possible explanation of these patterns has been examined.10acentres of endemism10aCOLEOPTERA10aDung beetles10aendemic species distributions.10aMediterranean region10aScarabaeoidea1 aLumaret, Jean-Pierre1 aLobo, Jorge, M.  uhttps://scarabnet.myspecies.info/geographic-distribution-endemic-dung-beetles-coleoptera-scarabaeoidea-western-palaeartic-region01481nas a2200181   4500008004100000245006200041210006000103260000800163300001000171490000600181520091700187653001101104653001801115653002301133100002501156700002501181856009301206       2003                        eng d00aDimorfismo sexual en larvas de Scarabaeoidea (Coleoptera)0 aDimorfismo sexual en larvas de Scarabaeoidea Coleoptera  csep  a15-180 v33 aA well defined sexual dimorphism is present in scarabaeoid larvae. Dimorphism was observed in late-age larvae of some species of Scarabaeidae, Aphodiidae, Trogidae, Orphinidae, Dynastidae, Passalidae and Lucanidae. This dimorphism manifests itself in the presence of a terminal ampulla, a cuticular structure situated in the ventral region of the 9th abdominal segment which is only present in male specimens. In Scarabaeidae, sexual dimorphism was only observed in the pupae of six species. The terminal ampulla in Canthon cyanellus cyanellus LeConte (Scarabaeidae) is present in the male larvae apparently since the first instar, and changes morphologically during the next larva instars. Only a detailed study of the morphogenesis of the terminal ampulla during the larval and pupal stages could help to define exactly what structures of the ejaculatory bulb and aedeagus it will turn into in the adult stage.10alarvae10aScarabaeoidea10asexual dimorphism.1 aM., Imelda, Martinez1 aLumaret, Jean-Pierre  uhttps://scarabnet.myspecies.info/dimorfismo-sexual-en-larvas-de-scarabaeoidea-coleoptera
