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

Evol 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‐

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 ...

Wounds on Rapanea melanophloeos provide habitat for a large diversity of Ophiostomatales including four new species [PDF]

Antonie Van Leeuwenhoek, 2016
Rapanea melanophloeos, an important canopy tree in Afromontane forests, is commonly utilised for medicinal bark harvesting. Wounds created from these activities provide entrance for many fungi, including arthropod-associated members of the Ophiostomatales and Microascales (ophiostomatoid fungi).

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.
