“…Most species captured in all habitat types were tunnelers, followed by rollers and dwellers, a result that appears to be the general pattern for dung beetles in the Neotropical region (Halffter et al 1992, Louzada and Lopes 1997, da Silva and Di Mare 2012, Campos and Hernández 2013, Silva et al 2015. In addition to being the most diverse group, tunnelers are also the most abundant dung beetles in all habitat types.…”

“…Dung beetles can be divided into three main nesting behavior guilds (hereafter, simply "guild") by the way they use the food resource: (1) rollers form balls of feces or carrion that they then roll and bury some distance from the source, (2) tunnelers bury feces or carrion at or very near the source, and (3) dwellers simply use the feces or carrion at the source without either tunneling or burying (Halffter and Matthews 1966, Halffter and Edmonds 1982, Hanski and Cambefort 1991. These resource-use guilds cause the dung beetle community to be sensitive to variation in landscape conditions, including soil texture, humidity and temperature (Halffter et al 1992, Almeida et al 2011, Silva et al 2015 and to habitat perturbation (Halffter et al 1992, Halffter and Favila 1993, Almeida et al 2011, Filgueiras et al 2011.…”

Although dung beetles are important members of ecological communities and indicators of ecosystem quality, species diversity, and how it varies over space and habitat types, remains poorly understood in the Brazilian Cerrado. We compared dung beetle communities among plant formations in the Serra Azul State Park (SASP) in the state of Mato Grosso, Brazil. Sampling (by baited pitfall and flight-interception traps) was carried out in 2012 in the Park in four habitat types: two different savanna formations (typical and open) and two forest formations (seasonally deciduous and gallery). A total of 5,400 individuals collected comprised 57 species in 22 genera. Typical savanna had the greatest species richness and abundance, followed by open savanna and deciduous forest, while the gallery forest had the fewest species but high abundance. Tunnelers (one of three main nesting behavior guilds) showed the greatest richness and abundance (except in the gallery forest, where one dweller species was extremely abundant) in all plant formations. We found that species richness and abundance of the dung beetle community are influenced by differences among plant formations. Habitat heterogeneity in the different plant formations along with anthropic influences (fire, habitat fragmentation) are cited as important factors that explain guild and species richness and distribution patterns. These results emphasize the importance of protected areas, such as SASP, for the maintenance and conservation of species diversity in the Brazilian Cerrado.

First report on dung beetles in intra-Amazonian savannahs in Roraima, Brazil

This is the first study to address the dung beetle (Coleoptera: Scarabaeidae: Scarabaeinae) diversity in intra-Amazonian savannahs in the state of Roraima, Brazil. Our aim was to survey the dung beetle fauna associated with these savannahs (regionally called 'lavrado'), since little is known about the dung beetles from this environment. We conducted three field samples using pitfall traps baited with human dung in savannah areas near the city of Boa Vista during the rainy seasons of 1996, 1997, and 2008. We collected 383 individuals from ten species, wherein six have no previous record in intra-Amazonian savannahs. The most abundant species were Ontherus appendiculatus (Mannerheim, 1829), Canthidium aff. humerale (Germar, 1813), Dichotomius nisus (Olivier, 1789), and Pseudocanthon aff. xanthurus (Blanchard, 1846). We believe that knowing the dung beetles diversity associated with the intra-Amazonian savannahs is ideal for understanding the occurrence and distribution of these organisms in a highly threatened environment, it thus being the first step towards conservation strategy development. Keywords: Tropical environments, new species occurrence, 'lavrado', Scarabaeinae. Resumo: Este é o primeiro estudo da diversidade de besouros rola-bosta (Coleoptera: Scarabaeidae: Scarabaeinae) nas savanas intra-amazô nicas de Roraima, Brasil. Nosso objetivo foi inventariar a fauna de besouros associada com savanas (conhecidas regionalmente como 'lavrado'), uma vez que pouco se sabe sobre esses besouros nesse ambiente. Nó s amostramos em savanas pró ximas a cidade de Boa Vista durante a estac¸ão chuvosa nos anos 1996, 1997 e 2008, utilizando armadilhas pitfall iscadas com fezes humanas. Coletamos 383 indivíduos de dez espécies, das quais seis nã o haviam ocorrência prévia para savanas intraamazô nicas. As espécies mais abundantes foram Ontherus appendiculatus (Mannerheim, 1829), Canthidium aff. humerale (Germar, 1813), Dichotomius nisus (Olivier, 1789) e Pseudocanthon aff. xanthurus (Blanchard, 1846). Nó s acreditamos que conhecendo a diversidade de besouros associada às savanas intra-Amazô nicas se torna ideal para o entendimento da ocorrência e distribuic¸ã o desses organismos em um ambiente altamente ameac¸ado, sendo o primeiro passo para a tomada de estratégias de conservac¸ão. Palavras-chave: Ambientes tropicais, nova ocorrência de espécies, lavrado, Scarabaeinae.
