“…Green cover has also been found to explain the distribution of dung beetles species in different-sized Atlantic forest fragments [80]. Variation in the percentage of green cover illustrates the differences among sites with greater or fewer small plants and shrubs covering the soil.…”

Understanding the ecological mechanisms driving beta diversity is a major goal of community ecology. Metacommunity theory brings new ways of thinking about the structure of local communities, including processes occurring at different spatial scales. In addition to new theories, new methods have been developed which allow the partitioning of individual and shared contributions of environmental and spatial effects, as well as identification of species and sites that have importance in the generation of beta diversity along ecological gradients. We analyzed the spatial distribution of dung beetle communities in areas of Atlantic Forest in a mainland-island scenario in southern Brazil, with the objective of identifying the mechanisms driving composition, abundance and biomass at three spatial scales (mainland-island, areas and sites). We sampled 20 sites across four large areas, two on the mainland and two on the island. The distribution of our sampling sites was hierarchical and areas are isolated. We used standardized protocols to assess environmental heterogeneity and sample dung beetles. We used spatial eigenfunctions analysis to generate the spatial patterns of sampling points. Environmental heterogeneity showed strong variation among sites and a mild increase with increasing spatial scale. The analysis of diversity partitioning showed an increase in beta diversity with increasing spatial scale. Variation partitioning based on environmental and spatial variables suggests that environmental heterogeneity is the most important driver of beta diversity at the local scale. The spatial effects were significant only at larger spatial scales. Our study presents a case where environmental heterogeneity seems to be the main factor structuring communities at smaller scales, while spatial effects are more important at larger scales. The increase in beta diversity that occurs at larger scales seems to be the result of limitation in species dispersal ability due to habitat fragmentation and the presence of geographical barriers.

“…As maiores riquezas de besouros escarabeíneos observadas em áreas de mata em relação a áreas com plantações de eucalipto podem ser explicadas devido a menor complexidade vegetal (e, por consequência, animal); homogeneidade do habitat; animais visitantes; menor diversidade de compostos orgânicos na serapilheira; condições microclimáticas desfavoráveis para algumas espécies (altas temperaturas, radiação solar e menor cobertura do solo para as larvas) (GARDNER et al, 2008b;RIEFF et al, 2010;BRAGA et al, 2013;CAMPOS;HERNÁNDEZ, 2013;. Gardner et al (2008b), trabalhando na Amazônia, defendem que, embora não possam ser considerados "desertos verdes", pois as espécies podem sobreviver em locais próximos à mata, áreas de eucalipto abrigam recursos limitados para as espécies desses locais.…”

ResumoReservas Legais visam à conservação de lorestas nativas e processos ecológicos, podendo formar mosaicos heterogêneos na paisagem. Este trabalho objetivou descrever e comparar assembleias de besouros escarabeíneos coprófagos para melhor entender a distribuição das espécies dentro da paisagem. A amostragem foi realizada em Içara (SC), em 2014, em ambientes com matas nativas, plantações de eucalipto, de milho e em pastagens. Foram utilizadas 10 armadilhas de atração para insetos vivos em cada local, recolhidas após 48 h. Foi coletado um total de 704 indivíduos e 16 espécies de Scarabaeinae, sendo as mais abundantes: Onthophagus catharinensis (n=213), Canthon smaragdulus (n=128) e Canthidium aff. trinodosum (n=112). Matas nativas obtiveram maiores riqueza e abundância. A similaridade de Bray-Curtis agrupou as assembleias dos ambientes de mata entre si (78% de similaridade), que diferiram das áreas com plantações de eucaliptos, assim como das assembleias de áreas abertas. Foram encontradas espécies com alto Valor Indicador Individual para ambientes de mata e de áreas abertas. A área de ligação entre matas teve grande importância, conectando áreas de mata nativa e auxiliando na conservação de espécies. Conforme o esperado, os resultados conirmam que ambientes mais preservados conservam maior biodiversidade, mas outros elementos da paisagem contribuem com a diversidade regional.

Sampling was conducted in the municipality of Içara (SC) in 2014, within environments of native forests, plantations of eucalyptus and corn, and pastures.

BackgroundConserving biodiversity in tropical landscapes is a major challenge to scientists and conservationists. Current rates of deforestation, fragmentation, and land use intensification are producing variegated landscapes with undetermined values for the conservation of biological communities and ecosystem functioning. Here, we investigate the importance of tropical variegated landscapes to biodiversity conservation, using dung beetle as focal taxa.MethodsThe study was carried out in 12 variegated landscapes where dung beetles were sampled using six pitfall traps, 30 m apart from each other, along a transect in each studied landscape use and cover classes—LUCC (forest fragment and corridor, coffee plantation, and pasture). We baited each pitfall trap with 30 g of human feces and left open for a 48 h period. We also measured three environmental variables reflecting structural differences among the studied classes: canopy cover, local vegetation heterogeneity and soil sand content.ResultsWe collected 52 species and 2,695 individuals of dung beetles. We observed significant differences in the mean species richness, abundance and biomass among classes, with forest fragments presenting the highest values, forest corridors and coffee plantations presenting intermediate values, and pastures the lowest values. Regarding community structure, we also found significant differences among classes. Canopy cover was the only variable explaining variation in dung beetle species richness, abundance, biomass, and community structure. The relative importance of spatial turnover was greater than nestedness-resultant component in all studied landscapes.DiscussionThis study evaluated the ecological patterns of dung beetle communities in variegated tropical landscapes highlighting the importance of these landscapes for conservation of tropical biodiversity. However, we encourage variegation for the management of landscapes that have already been fragmented or as a complementary initiative of current conservation practices (e.g., protection of natural habitats and establishment of reserves).
