But species loss in forest fragments is a complex process and appears often only after considerable time lags, especially in vertebrates (Brooks et al. 1999b). Therefore, empirical evidence for such extinctions can only be obtained from areas with a long deforestation history and long-known faunal composition (e.g. van Balen 1999). Such empirical data are scarce but are essential in order to convince land use managers of the long-term effects of forest loss on biodiversity. Species area models, however, are a valuable tool in the prediction of tropical vertebrate species loss (van Balen 1999; Brooks et al. 1997, 1999a, c, 2002; Cowlishaw 1999)."],["dc.identifier.doi","10.1007/978-3-662-08237-9_19"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/65139"],["dc.language.iso","en"],["dc.publisher","Springer"],["dc.relation.eisbn","978-3-662-08237-9"],["dc.relation.isbn","978-3-642-05617-8"],["dc.relation.ispartof","Land Use, Nature Conservation and the Stability of Rainforest Margins in Southeast Asia.

An increasing number of studies indicate that much forest biodiversity can also be found in the agricultural landscape matrix. Because there is little information on the potential value of land-use systems for tropical forest bird species, we conducted repeated point counts in near-primary forest, adjacent young secondary forest, modernized cacao agroforestry systems, and annual cultures at submontane elevations in central Sulawesi, Indonesia. Species richness decreased from natural forest and young secondary forest to agroforestry systems and annual cultures. Although species richness was similar between natural and young secondary forest, the number of endemic bird species was significantly lower in second-growth forest. Species composition gradually changed as the habitat changed from natural to secondary forest, agroforestry systems, and annual cultures. Despite close proximity to near-primary forest, the agroforestry systems studied supported only a few small frugivorous-nectarivorous species. Our results suggest that secondary forest could play an important role in the conservation of many Sulawesi bird species, but, although suitable for colonization, its potential to sustain populations over the long term is unknown. Improvement of the landscape matrix for biodiversity conservation through secondary habitats therefore seems desirable to enlarge the ranges of forest species, but the fight against land conversion within protected areas of the region should be of much higher importance, at least at present."],["dc.identifier.doi","10.1111/j.1523-1739.2004.00127.x"],["dc.identifier.isi","000224071800019"],["dc.identifier.uri","https://resolver.sub.uni-goettingen.de/purl?gro-2/47416"],["dc.notes.status","zu prüfen"],["dc.notes.submitter","Najko"],["dc.publisher","Blackwell Publishing Inc"],["dc.relation.issn","0888-8892"],["dc.title","Effects of land use on bird species richness in Sulawesi, Indonesia"],["dc.type","journal_article"],["dc.type.internalPublication","yes"],["dc.type.peerReviewed","yes"],["dc.type.status","published"],["dspace.entity.type","Publication"]]

The results showed that Ospreys preferred landscapes with more water bodies and forests. Such sites were also occupied earlier and had higher local population density. However, in the study period of 11 years, there was a gradual shift from forest-dominated landscapes to agricultural land-dominated landscapes. The breeding success increased over time, with no difference in the breeding success between pairs nesting on trees and poles, whereas there was higher breeding success at nest sites surrounded by more agricultural land and less forest. The more efficient foraging in eutrophic lakes in agricultural landscapes was the most likely cause for the higher breeding success.

On four study plots along a gradient of human land-use we determined population densities, home range sizes, nightly path lengths and group sizes of T. dianae.

We found the smallest home ranges in slightly disturbed forest. In a heavily disturbed plantation densities were low, and ranges and nightly path lengths were large.

In the Congo Basin rainforests, species within this weight range are also targeted by bushmeat hunters, potentially leading to exploitative competition between leopards and hunters. We investigated leopard prey choice along a gradient of human disturbance, hypothesizing that leopards will exploit smaller prey where competition is strong, possibly resulting in reduced leopard densities at highly hunted sites. We determined leopard diet by means of scat analysis at four rainforest sites in central Gabon, which varied according to their distance from human settlements. Camera trap data collected at each of the four study sites revealed that human hunting intensity increased with proximity to settlements, while the abundance of potential leopard prey species decreased. We found no evidence of leopards at the site nearest to settlements. At the remaining sites, the number of scats collected, mean leopard prey weight and the proportion of large prey (420 kg) in leopard diet increased with distance from settlements. Camera trap data demonstrated that leopard population density increased with distance from settlements, from 2.7 perpendicular to 0.94 leopards/100 km(2) to 12.1 perpendicular to 5.11 leopards/100 km(2). Our results document an increasing use of smaller prey species and a decrease in leopard density in proximity to settlements, supporting our hypothesis. Comparison of leopard diet with hunter return data revealed a high dietary niche overlap between leopards and hunters at sites situated at similar distances from settlements.

We studied bird communities and vegetation characteristics in 24 sampling stations distributed over two near-natural forests (near-primary forest, secondary forest), and two land use types (agroforestry, annual cultures) in the lowlands of the Korup region, Cameroon. Repeated sampling was used to establish near-complete inventories of bird assemblages for each site. Despite a 90% average drop in tree basal area, from forest to farmland, overall bird species richness did not decrease significantly with increasing habitat modification. However, different groups of birds responded in different ways. Frugivorous and omnivorous bird species richness did not differ between habitats, whereas richness in granivorous, flower-visiting, and nonbreeding species was higher in land use systems compared to forests. In contrast, insectivorous birds, especially terrestrial and large arboreal foliage gleaning insectivores, and ant followers showed,a declining species richness from forest to farmland. Also, richness in species of those restricted to the Guinea-Congolian forest biome and of the family Pycnonotidae showed a pronounced decline with increasing habitat modification. Species richness of overall insectivores, terrestrial insectivores, large- and medium-sized arboreal foliage gleaners, ant followers, as well as pycnonotids and biome-restricted species, were strongly or even very strongly positively correlated with overstory tree density and, in most cases, also with basal area. In contrast, tree density and basal area were strongly negatively correlated with species richness of nonbreeding visitors and flower-visiting bird species. Species composition was most distinct between near-primary forest and annual culture sites, and the abundance of 23 out of 165 species was affected by habitat, suggesting considerable partitioning of habitat niches along the habitat gradient.
