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.

“…Para o Nordeste brasileiro, poucos são os trabalhos encontrados na literatura com Coleoptera. As pesquisas têm se concentrado em amostragens com a utilização de armadilhas Malaise (Iannuzzi et al, 2003;Maia et al, 2003;Iannuzzi et al, 2006), armadilhas de solo, Malaise e guarda-chuva entomológico (Vasconcellos et al, 2010), armadilhas de luz (modelo Luiz de Queiroz), rede entomológica e/ou armadilhas com iscas para Cerambycidae (Nascimento & Bravo, 2014;Nascimento et al, 2016) e com iscas para escarabeídeos (Hernández, 2005(Hernández, , 2007Lopes & Louzada, 2005;Lopes et al, 2006;Liberal et al, 2011;Salomão et al, 2014;Salomão & Iannuzzi, 2015;Silva et al, 2017;Vieira et al, 2017). No entanto, tais pesquisas são restritas a poucas famílias de Coleoptera.…”

RESUMO Os besouros apresentam grande diversidade taxonômica e funcional, no entanto, para a Região Nordeste, especialmente para a porção com vegetação de Caatinga, o conhecimento da fauna de Coleoptera é muito restrito. Por se tratar de uma região com grande diversidade de paisagens, torna-se necessário conhecer a coleopterofauna que ocorre nas diferentes fitofisionomias, buscando com isso abranger a variabilidade espacial encontrada nessa região xérica. Diante disso, o objetivo deste estudo foi realizar um levantamento das espécies de besouros no Semiárido paraibano. As coletas foram realizadas semanalmente durante quatro anos (2009-2013) utilizando uma armadilha Malaise por fitofisionomia, sendo amostrada uma área com vegetação xerófila e outra com mata ciliar. Foram coletados 6.567 indivíduos pertencentes a 383 espécies e 42 famílias de Coleoptera. Chrysomelidae (78 spp.), Curculionidae (57 spp.) e Cerambycidae (28 spp.) foram as famílias mais ricas. Em relação às mais abundantes, Chrysomelidae (30,4% dos indivíduos), Curculionidae (8,3%) e Tenebrionidae (7,7%) se destacaram. Foi verificado um elevado número de singletons e doubletons, apesar do prolongado período amostral, indicando que deve haver ainda muitas espécies a serem registradas na área de estudos. Nossos resultados demonstram uma rica fauna de besouros na região semiárida estudada e fornece uma lista de besouros de ocorrência no Semiárido paraibano, com novos registros de espécies para o estado e contribui assim com o conhecimento da diversidade de Coleoptera no Nordeste do Brasil.

“…This relationship was underlined in a study where Odonata species richness decreased with increasing amounts of forest, especially at a 200 m scale 28 . Although the role of forests for Odonata has a great literature 5,14,34 our result shows that for the lowland Zygoptera species the increased amount of woodland could be an obstructive factor.…”

“…Human-caused habitat loss and fragmentation became the major threatening factor during the last few decades for several taxa 11 . While several studies explore the influence of habitat loss on terrestrial populations and communities 12–14 relatively few studies focus on the relationship between landscape change and aquatic invertebrates such as Odonata. These insects are strongly connected with water bodies and regarded to be influenced mostly by the aquatic environment.…”
