Analysis of Land Cover Changes in Afromontane Vegetation of Image Forest Reserve, Southern Highlands of Tanzania. [PDF]

ScientificWorldJournal, 2020
An analysis of land cover changes (LCCs) was done in Image Forest Reserve (IFR) from August to October 2019. Free satellite images for 1990, 2004, and 2018 were downloaded from Landsat 5 (TM) and Landsat 8 (OLI) available through the USGS portal. Ground surveys were conducted using systematically set plots of 20 m × 40 m to identify the existing land ...

Widespread introduced species dominate the urban tree assemblage on the endemic-rich tropical island of São Tomé. [PDF]

Ecol Evol
Afrotropical cities are growing rapidly but how this impacts biodiversity is largely unclear. Our study on São Tomé Island, Central Africa, reveals that the urban tree assemblage is impoverished and dominated by introduced species, while the natural forest is essential for the protection of native and endemic species.

High Inter-Specific Diversity and Seasonality of Trunk Radial Growth in Trees Along an Afrotropical Elevational Gradient. [PDF]

Plant Cell Environ
ABSTRACT Understanding mechanisms driving tropical tree growth is essential for comprehending carbon sequestration and predicting the future of tropical forests amid rapid deforestation. We conducted a natural experiment in Mount Cameroon to identify climatic factors limiting diurnal and seasonal growth in dominant tree species across a 2200‐m ...

The Immune Effects of an African Traditional Energy Tonic in In Vitro and In Vivo Models. [PDF]

Evid Based Complement Alternat Med, 2017
Most of the African traditional medicines (ATM) are formulated as energy tonics to boost and maintain immune defences. In this study, we aimed to evaluate the immune effects of a traditional energy tonic using peripheral blood mononuclear cells (PBMCs), THP‐1 monocytes, and bacteria infected rats.

Anthelmintic Agents from African Medicinal Plants: Review and Prospects

Evidence-Based Complementary and Alternative Medicine, Volume 2022, Issue 1, 2022., 2022
Soil‐transmitted helminthiasis affects more than 1.5 billion people globally and largely remains a sanitary problem in Africa. These infections place a huge economic burden on poor countries and affect livestock production, causing substantial economic losses and poor animal health. The emergence of anthelmintic resistance, especially in livestock, and

The Effects of Landscape Change on Plant Diversity and Structure in the Bale Mountains National Park, Southeastern Ethiopia

International Journal of Ecology, Volume 2021, Issue 1, 2021., 2021
Bale Mountains National Park is one of the protected areas in Ethiopia that holds the largest area of Afroalpine habitat in Africa and the second largest stand of moist tropical forest. Nevertheless, human settlements, overgrazing, and recurrent fire are the main problems in the park. This study aimed to determine the effects of human‐induced landscape
