Tropical forest recovery from logging: a 24 year silvicultural experiment from Central Africa

Large areas of African moist forests are being logged in the context of supposedly sustainable management plans. It remains however controversial whether harvesting a few trees per hectare can be maintained in the long term while preserving other forest services as well. We used a unique 24 year silvicultural experiment, encompassing 10 4 ha plots established in the Central African Republic, to...

Cardiomegaly in tropical Africa.

The term "cardiomegaly" is found in 5-7% of chest X-ray film evaluations in tropical Africa. However, "cardiomegaly" is a descriptive term, devoid of any aetiological meaning. Therefore, providing information about the aetiological factors leading to heart enlargement in a group of Africans (Nigerians) was the purpose of this study. In the years 2002-2011, 170 subjects (aged 17-80 years, mean a...

Bilharziasis in tropical Africa.

Comparative phylogeography of three endemic rodents from the Albertine Rift, east central Africa.

The major aim of this study was to compare the phylogeographic patterns of codistributed rodents from the fragmented montane rainforests of the Albertine Rift region of east central Africa. We sampled individuals of three endemic rodent species, Hylomyscus denniae, Hybomys lunaris and Lophuromys woosnami from four localities in the Albertine Rift. We analysed mitochondrial DNA sequence variatio...

Venereal syphilis in tropical Africa.

A steady decline in the incidence of positive results to the Kahn test is reported in Malawian patients during the period 1968-75. Other studies have shown that the incidence of early and late syphilis in sub-Saharan Africa has dropped considerably over the past few decades. The number of reported cases of early syphilis in certain urban areas, however, appears to be high. It is suggested that ...
