Use of microhabitats affects butterfly assemblages in a rural landscape Pap. Avulsos de Zool. (São Paulo)
Orlandin,Elton; Piovesan,Mônica; D’Agostini,Fernanda Maurer; Carneiro,Eduardo.
Abstract Landscapes composed of small rural properties may support highly heterogeneous habitat, because they often cover distinct types of land uses adjacent to surrounding forest fragments. Many butterfly species may benefit from this kind of landscape, as very distinct microhabitats can be found in a very restricted spatial scale. To better understand how different microhabitats are related to fragmentation in rural landscapes the present study collected the butterfly fauna in 18 sampling point sites, representing distinct types of forest edges and forest interiors. Although closely located, these sites showed no spatial autocorrelation. Instead, a major distinction in species richness and composition was found among forest interior and edge habitats...

Community dynamics in a species-rich patch of old-growth forest in a global changing scenario Acta Botanica
Gastauer,Markus; Meira Neto,João Augusto Alves.
Ecological theory predicts that, in mature ecosystems, species richness, the number of individuals and the biomass of individuals will remain in a relatively stable state of equilibrium. The aim of this study was to test that theory. In 2001 and 2010, we conducted censuses of all trees with a circumference at breast height > 10 cm in a one-hectare plot in a seasonal semideciduous old-growth forest in southeastern Brazil. We compared the two censuses in terms of species richness and diversity, computing growth, recruitment and mortality rates, as well as gains and losses of basal area. Between 2001 and 2010, species richness declined from 224 to 218 species and the basal area increased from 37.86 to 40.16 m² ha-1. Overall turnover (the mean...
