Impact of landscape composition and configuration on forest specialist and generalist bird species in the fragmented Lacandona rainforest, Mexico
With accelerated land-use change throughout the tropics, an increasing proportion of global biodiversity is located in human-modified landscapes. Understanding the relative effects of landscape composition and configuration on biodiversity is needed to design effective conservation strategies. Yet this topic is poorly understood because most studies have been performed at the patch scale, and d...
متن کاملTrait-Specific Responses of Wild Bee Communities to Landscape Composition, Configuration and Local Factors
Land-use intensification and loss of semi-natural habitats have induced a severe decline of bee diversity in agricultural landscapes. Semi-natural habitats like calcareous grasslands are among the most important bee habitats in central Europe, but they are threatened by decreasing habitat area and quality, and by homogenization of the surrounding landscape affecting both landscape composition a...
متن کاملCoccinellid response to landscape composition and configuration
1 Arthropod natural enemies provide valuable pest suppression in agricultural landscapes. Natural enemy abundance and diversity within a given crop, in turn, have frequently been shown to be positively related to the amount of semi-natural habitat in the landscape. However, other aspects of landscape structure may also influence natural enemy communities and may be more amenable to management. ...
متن کاملNutrition or Detoxification: Why Bats Visit Mineral Licks of the Amazonian Rainforest
Many animals in the tropics of Africa, Asia and South America regularly visit so-called salt or mineral licks to consume clay or drink clay-saturated water. Whether this behavior is used to supplement diets with locally limited nutrients or to buffer the effects of toxic secondary plant compounds remains unclear. In the Amazonian rainforest, pregnant and lactating bats are frequently observed a...
متن کاملLong-term landscape change and bird abundance in Amazonian rainforest fragments.
The rainforests of the Amazon basin are being cut by humans at a rate >20,000 km2/year leading to smaller and more isolated patches of forest, with remaining fragments often in the range of 1-100 ha. We analyzed samples of understory birds collected over 20 years from a standardized mist-netting program in 1- to 100-ha rainforest fragments in a dynamic Amazonian landscape near Manaus, Brazil. A...
