Modeling roan and sable patterns of spatial distribution in the Mudumu National Park, Namibia

Wildlife Society Bulletin, Volume 49, Issue 1, March 2025.
Abstract Large ungulates across the world are threatened with extinction due to habitat loss, land use change, and other anthropogenic pressures. While conservation measures are critical, for many populations the implementation of conservation measures is often not practical, either due to a lack of information on the species' biology or their ...

The life cycle of Puccinia digitariae on Digitaria eriantha and Solanum species in South Africa

, 2022
Rust fungi are important plant pathogens and have been extensively studied on crops and other host plants worldwide. This study describes the heterecious life cycle of a rust fungus on Digitaria eriantha (finger grass) and the Solanum species S ...

The Influence of Bush Encroachment on the Abundance and Species Richness of Rodents in a Mesic Savanna

African Journal of Ecology, Volume 62, Issue 4, December 2024.
ABSTRACT The study assessed the influence of woody plant encroachment on the diversity of rodents in mesic savannas at the Roodeplaat and Goss Farms in South Africa. Some 142 animals from six species were recorded in 1748 trap nights. The non‐encroached habitat showed twice the species richness of encroached habitats, and three species were notably ...

PRODUCTIVITY OF A SILVOPASTORAL SYSTEM UNDER INTENSIVE MIXED SPECIES GRAZING BY CATTLE AND SHEEP

Tropical and Subtropical Agroecosystems, 2011
The presence of forage trees in pastures enhances yield and nutritional quality of forage available for animal feeding. We assessed forage yield and nutritional quality, and weight gain of cattle and sheep foraging in a silvopastoral system containing ...

Context‐dependent directional effects of termite mounds on soil nutrients, vegetation communities, and mammalian foraging

Ecosphere, Volume 15, Issue 9, September 2024.
Abstract Termite mounds are keystone structures in African savannas, affecting multiple ecosystem processes. Despite the large size of termite mounds having the potential to modify conditions around them, patterns of mound‐induced ecosystem effects have been assumed to be isotropic, with little attention given to how effects might vary around mounds ...

Carbon isotope trends across a century of herbarium specimens suggest CO2 fertilization of C4 grasses

New Phytologist, Volume 243, Issue 2, Page 560-566, July 2024.
Summary Increasing atmospheric CO2 is changing the dynamics of tropical savanna vegetation. C3 trees and grasses are known to experience CO2 fertilization, whereas responses to CO2 by C4 grasses are more ambiguous. Here, we sample stable carbon isotope trends in herbarium collections of South African C4 and C3 grasses to reconstruct 13C discrimination.
