Host evolutionary relationships explain tree mortality caused by a generalist pest-pathogen complex. [PDF]

open access: yesEvol Appl, 2021
Abstract The phylogenetic signal of transmissibility (competence) and attack severity among hosts of generalist pests is poorly understood. In this study, we examined the phylogenetic effects on hosts differentially affected by an emergent generalist beetle–pathogen complex in California and South Africa. Host types (non‐competent, competent and killed‐

Isolation, characterisation and biological activity of some compounds from rapanea melanophloeos (L.) Mez. [PDF]

open access: yes, 2012
M.Sc. The continued use and popularity of plant based traditional medicine necessitates scientific validation of the therapeutic potential of medicinal plants through phytochemical and pharmacological screening as well as the isolation and identification of bioactive compounds.

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

open access: yesEcol 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.

Exploring Bioactive Phytomedicines for Advancing Pulmonary Infection Management: Insights and Future Prospects. [PDF]

open access: yesPhytother Res
ABSTRACT Pulmonary infections have a profound influence on global mortality rates. Medicinal plants offer a promising approach to address this challenge, providing nontoxic alternatives with higher levels of public acceptance and compliance, particularly in regions where access to conventional medications or diagnostic resources may be limited ...

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

open access: yesPlant 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]

open access: yesEvid 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

open access: yesEvidence-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

open access: yesInternational 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
