Abstract We studied the population dynamics of endangered mountain nyala Tragelaphus buxtoni between 2003-2005 in the Bale Mountains National Park. Line-transect sampling and total count methods were used to gather data on demographics and movement patterns. The population's age-group composition was 58% adults, 25% sub-adults, 9% juveniles, 5% calves and 3% unidentified with a female-male sex ratio of 2:1. Population density was found to be significantly different between the two sub-populations (Dinsho Sanctuary and Gaysay/Adelay). A significant difference was found for age-group composition

Abstract:
This paper examines the nature of community management of woodlots and investigates the determinants of collective action and its effectiveness in managing woodlots, based on a survey of 100 villages in Tigray, northern Ethiopia. Despite limited current benefits received by community members, the woodlots contribute substantially to community wealth, increasing members' willingness to provide collective effort to manage the woodlots. We find that benefits are greater and problems less on woodlots managed at the village level than those managed at a higher municipality level, and that the avera

Abstract Objectives Both body fat and lean body mass have important roles in health and wellbeing. It is crucial that researchers and clinicians can accurately measure them, especially in nutritionally vulnerable populations such as people living in rural areas of Ethiopia. Skinfold thickness measurements are one of the few methods to measure % body fat outside of a clinical setting. The validity of the measurements is dependent upon age, sex, and ethnicity. The existing skinfold thickness equations are derived from populations of European descent. This study will demonstrate that existing equ

Land use and land cover (LULC) change through inappropriate agricultural practices and high human and livestock population pressure have led to severe land degradation in the Ethiopian highlands. This has led to further degradation such as biodiversity loss, deforestation, and soil erosion. The study examined woody vegetation diversity status and the impact of drivers of change across different LULC types and agroecological zones in Gilgel Tekeze catchment, northern Ethiopian highlands. LULC dynamics were assessed using GIS techniques on 1976, 1986, and 2008 satellite images. Vegetation data w

AbstractThe Bale monkey Chlorocebus djamdjamensis is a little-known primate endemic to the south-eastern highlands of Ethiopia. From August 2007 to May 2008 we surveyed to determine the species' habitat preferences and population size in the Odobullu Forest and its range across the Bale Mountains. In Odobullu Forest a total of 136 transects of 1.8–3.0 km were surveyed over a total distance of 280 km. Bale monkey groups were encountered only in bamboo forest, suggesting that the species is a bamboo forest specialist. The density and population size of the Bale monkey in the bamboo forest of Odo
