Occurrences of forest butterflies in the farm bush savannah outside a forest reserve in Ghana, West Africa

摘要: The willingness of a species to leave forest fragment is prerequisite for subsequent dispersal across the intervening non-forested landscape. Species with stringent fidelity patch will be isolated from populations in other fragments and predisposed factors that promote extinction local populations. Here, we document which fruit-feeding, forest-dwelling butterflies occur farm bush savannah outside an afrotropical reserve order gain first approximation those potentially dispersing it. Standard fruit-baited traps hung at 80 m inside forest, edge 12 50 into matrix were used characterize communities different habitats. A total 1616 specimens collected 19 traps, representing 90 species. Rarefied richness was generally comparable Multivariate ordination analyses, integrate composition relative abundance addition richness, uncovered two broad community types, i.e. (edge plus inside) matrix. Relative habitat investigated 45 represented by least five individuals. More than half forest-associated showed relaxed commonly trapped Although generalists dry expected more wet or moist species, there no relationship between occurrence versus their association category.
