Both species show similar daily activity. They coexist in grasslands bordering on tropical forest opened for cattle activity. Results show spatial segregation at local level: both species inhabit open areas but O. batesi less so. This latter species also inhabits the forest, mainly at the edge zones. The possible causes of this spatial segregation along the environmental gradient could be related with a different detection capacity of the two species. Since their flying activity occurs at dusk and dawn, we suggest that the detection of humidity has an important role in the observed segregation. We propose that the adults colonize dung pats located in places with suitable environmental conditions that secure progeny survivorship. However. the possibility of competition between these species, cannot be ruled out. From a historic-evolutive perspective the coexistence of both species is recent. It is necessary to determine the spatial behavior of either species where the other one is missing. What happens with possible interactions in overlapping zones (edge-grassland) and studies about immigration-emigration rates from dung pats in these zones, where the two species coexist, are questions for future research.10aa10aAnimalia-10aAnimals-10aArthropoda-10aBehavior-10aClimatology- (Environmental-Sciences)10aColeoptera-: Insecta-10aDigitonthophagus-gazella (Organisms-Unspecified)10aEcology- (Environmental-Sciences)10aInvertebrata-10aOnthophagus-batesi (Coleoptera-)10aPhysiology-1 aLobo, Jorge, M.1 aMontes, De, Oca Enriqu  uhttps://scarabnet.myspecies.info/local-distribution-and-coexistence-digitonthophagus-gazella-fabricius-1787-and-onthophagus-batesi-ho02273nas a2200313   4500008004100000245016400041210006900205300001000274490000700284520116400291653001401455653001301469653003001482653001601512653001601528653001801544653002601562653003301588653004601621653001201667653001301679653001801692653001901710653002401729100002001753700002201773700002601795856013801821       1997                        eng d00aDiversity and spatial turnover of dung beetle (Coleoptera: Scarabaeoidae) communities in a protected area of South Europe (Donana National Park, Huelva, Spain)0 aDiversity and spatial turnover of dung beetle Coleoptera Scaraba  a71-880 v113 aDiversity and spatial turnover of the spring dung beetle community of Donana National Park (Huelva, Spain), one of the most important wildlife reserves in the Mediterranean area, were examined. The entire dung beetle community is estimated to comprise around 68 species. Coastal dunes and marsh proved to be the most singular habitats within Donana Reserve. Response of Scarabaeidae and Aphodiidae to habitat heterogeneity was different. Scarabaeidae fauna was highly homogeneous throughout the habitats whereas Aphodiidae showed higher rates of species turnover and some singular local communities, thus contributing to a greater extent to the regional diversity. Scarabaeidae family presents more ubiquitous species and lower values of beta diversity, so that its local and regional diversity converge. It is suggested that different adaptive strategies regard in resource partitioning (Scarabaeidae: tunnellers and ball-rollers; Aphodiidae: dwellers) can account for these differences. Although Donana National Park is home to a richer wild mammal fauna and non-human altered habitats, its dung beetle diversity is similar to that of other Spanish regions.10aAnimalia-10aAnimals-10aAphodiidae- (Coleoptera-)10aArthropoda-10aArthropods-10aBiodiversity-10aColeoptera-: Insecta-10aDonana-National-Park (Spain-10adung-beetle (Coleoptera-): Scarabaeoidea-10aEurope-10aInsects-10aInvertebrata-10aInvertebrates-10aPalearctic-region):1 aLobo, Jorge, M.1 aSanmartin, Isabel1 aMartin, Piera, Fermin  uhttps://scarabnet.myspecies.info/diversity-and-spatial-turnover-dung-beetle-coleoptera-scarabaeoidae-communities-protected-area-south
