Forest fragmentation and selective logging are two main drivers of global environmental change and modify biodiversity and environmental conditions in many tropical forests. The consequences of these changes for the functioning of tropical forest eco

Bee diversity along a forest regeneration gradient in Western Kenya

Autor: David Irungu, Dieter Wittmann, Manfred Kraemer, Mary Gikungu

Publikováno v: Journal of Apicultural Research. 50:22-34

Changes in bee species richness and diversity were studied along a forest regeneration gradient in seven sites in Buyangu Nature Reserve, Kakamega Forest, Kenya. At each site, 12 belt transects of 100 m length and 2 m width were established. The sele

Inadequate pollination is a major constraint to crop yield. Momordica charantia L. is a fruit crop of economic interest in Kenya. Pollination ecology, pollinator diversity and their behaviour were studied in Western Kenya. Pollination treatments incl

Agricultural surroundings support flower-visitor networks in an Afrotropical rain forest

Autor: Manfred Kraemer, Melanie Hagen

Local habitat structure and resource availability appear to be of great importance for the diversity, abundance, and community structure of bees. We examined the contribution of three different habitat types (farmland, forest edge, forest understory)

Farmers' knowledge of bees and their natural history in Kakamega district, Kenya

Autor: Christopher Martius, Manfred Kraemer, Dieter Wittmann, Muo Kasina

The Kakamega district is endowed with good climatic and soil conditions that have favoured agricultural production, and houses the Kakamega Tropical Rain Forest, the only remaining patch of the easternmost end of the Congo Forest. In efforts to halt
