Estrutura da comunidade de Scarabaeinae (Scarabaeidae: Coleoptera) em fitofisionomias do cerrado e sua importância para a conservação

Abstract: -The spatial changes in species composition are closely related to the environmental aspects associated to habitat variation. The natural landscapes of Minas Gerais are organized in mosaics, associated to anthropic action or natural factors. Here we study dung beetles in the Perdizes Plateau, Carrancas (Minas Gerais, Southeastern Brazil). The area of study has a landscape composed mainly by four phytophysiognomies: Brazilian savannah, altitudinal grasslands, rupestrian fi elds and forests. The objective of our… Show more

“…The composition of ichthyocenosis and structure differences along the longitudinal gradient are influenced by differential contributions of phytophysiognomies in determining specific structural patterns on stream banks. This provides support for the generalization that phytophysiognomic diversity is fundamental for the maintenance of biodiversity in the Brazilian Cerrado (Mares et al, 1986;Ratter et al, 1997;Oliveira & Marquis, 2002;Almeida & Louzada, 2009). …”

“…Besides the records provided here, C. marseuli is reported only in rupestrian fields in south of state of Minas Gerais (Almeida & Louzada 2009) while Canthon lamproderes was registered also in rupestrian fields at Serra da Canastra and Serra do Espinhaço, both on south of the state of Minas Gerais (CEMT Records)…”

“…Esses resultados contrariaram a hipótese de que o aumento da heterogeneidade de habitat promoveria aumento da riqueza de animais (revisão: Tews et al 2004). Porém, corroboram vários trabalhos que demonstraram o efeito de variáveis ambientais na composição e estrutura da assembléia de besouros rola-bostas (Nichols et al 2007, Davis et al 2008, Gardner et al 2008, Jay-Robert et al 2008, Almeida & Louzada 2009. A relação de maior riqueza de espécies em locais com menor heterogeneidade de habitat também foi encontrada em estudos com o mesmo tipo de fi tofi sionomias em diferentes áreas do cerrado brasileiro (Milhomem et al 2003).…”

“…Formam assembléias bem defi nidas em termos taxonômicos e funcionais (Halffter & Matthews 1966, Halffter 1991) e respondem prontamente a alterações e modifi cações no habitat, sejam elas de origem antrópica, como a fragmentação (Howden & Nealis 1975, Klein 1989, Nichols et al 2007, Gardner et al 2008, ou mudança natural na estrutura da vegetação (Durães et al 2005, Davis et al 2008, Almeida & Louzada 2009). Tais mudanças podem afetar a riqueza e a composição da assembléia desses besouros (Nichols et al 2007, Gardner et al 2008, Jay-Robert et al 2008, Davis et al 1999, 2008.…”
