Known Elephant Distribution in Africa: An Updated Map

An empirical malaria distribution map for West Africa.

The objective of this study was to produce a malaria distribution map that would constitute a useful tool for development and health planners in West Africa. The recently created continental database of malaria survey results (MARA/ARMA 1998) provides the opportunity for producing empirical models and maps of malaria distribution at a regional and eventually at a continental level. This paper r...

The Capacity of Known Interference Channel (updated)

In this paper, we investigate the capacity of known interference channel, where the receiver knows the interference data but not the channel gain of the interference data. We first derive a tight upper bound for the capacity of this known-interference channel. After that, we obtain an achievable rate of the channel with a blind known interference cancellation (BKIC) scheme in closed form. We pr...

An updated linkage and comparative map of porcine chromosome 18.

Swine chromosome 18 (SSC18) has the poorest marker density in the USDA-MARC porcine linkage map. In order to increase the marker density, seven genes from human chromosome 7 (HSA7) expected to map to SSC18 were selected for marker development. The genes selected were: growth hormone releasing hormone receptor (GHRHR), GLI-Kruppel family member (GLI3), leptin (LEP), capping protein muscle Z-line...

Conservation science and elephant management in southern Africa

THE PREVAILING INCREASE IN ELEPHANT numbers across areas of southern Africa raises concern for their impact on biological diversity. Several approaches to elephant management focus on limiting numbers to alleviate these consequences. However, landscape fragmentation, fences, water supplementation as well as the shape and size of some conservation areas restrict range use and intensify the effec...
