The Mekong River is one of the great rivers of the world and is characterized by high fish biodiversity (Valbo-Jorgensen et al. 2009). The Mekong region is in fact a fish biodiversity hotspot whose richness is only now being revealed. During the last decade more than 279 new species of fish have ...

Earthworm populations (predominantly Hyperiodrilus africanus and Eudrilus eugeniae) were sampled monthly for 1 yr during 1994 and 1995 in natural regrowth vegetation fallow (dominated by the natural fallow shrub Chromolaena odorata L.), planted fallow (the woody species Senna siamea Lam., Leucaen...

Result of long time alley cropping trials show that the inclusion of N2- fixing hedgerow species maintain higher levels of soil fertility than control treatment (no hedgerow) on high base status soils in the humid zone. Hedgerows contribute to nutrient cycling and higher faunal activity. With goo...

A study was undertaken to assess the effect of different pruning intervals of Leucaena leucocephala hedgerows on alley cropped maize and cassava. Farmers often delay hedgerow pruning in alley cropping systems due to labor, and financial constraints. It is not clear, however, when hedgerow shading...

Field trials were carried out on a Dystric Nitosol at Calavi in the subhumid zone of southern Benin Republic, West Africa from 1989-1997. A split plot design with four replications was used. There were (our main plots: control (no hedgerow), Leucaena hedgerows, Acacia hedgerows and mixed Leucaena...

Below-ground root competition between Leucaena hedgerow and intercropped maize and cowpea was evaluated on an Alfisol in the humid zone of southwestern Nigeria. Four-meter spaced hedgerows were established in 1983, and trials carried out with sequentially cropped maize and cowpea in 1990 and 1991...
