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 ...

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.

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 ...

Establecimiento de pasto plumerito (Trichloris crinita Parodi) en el año de siembra

Semiárida, 2020
El bosque de algarrobo en Mendoza presenta una serie de estados estables de baja productividad con un alto grado de arbustización. En estas condiciones, el uso del rolo cortador como herramienta de control del arbustal mejora dichos ambientes. La siembra

Habitat modifies the relationship between grass and herbivore species richness in a South African savanna

Ecology and Evolution, Volume 14, Issue 4, April 2024.
We show the relationship between grass and herbivore species richness. We suggest that the relationships between grasses and herbivores may work in both directions, but the relationship is habitat‐dependent, so that in less productive environments the effect of herbivores on vegetation prevails, while in more productive environments along rivers, the ...

In vitro gas production and in vivo nutrient digestibility and growth performance of Thai indigenous cattle fed fresh and conserved pangola grass

Italian Journal of Animal Science, 2017
Fresh and conserved pangola grass (Digitaria eriantha Steud., synonym D. decumbens) were compared in terms of in vitro gas production and in vivo nutrient digestibility, metabolisable energy (ME) concentration and average daily gain (ADG) of Thai ...

Potential Use of Herbicide Seed Safener and Pre-Emergent Residual Herbicides When Establishing Tropical Perennial Grasses—A Preliminary Study

Seeds
Annual grass weeds can provide significant competition to an establishing sown tropical perennial grass pasture. At least two years of grass weed control prior to sowing is required to reduce the weed seed bank.

The effect of closing date on the performance of beef weaners grazing foggaged Digitaria eriantha and Acroceras macrum

South African Journal of Animal Science, 2000
Digitaria eriantha spp. eriantha and Acroceras macrum foggage, closed off at three different dates (end of December, end of January and end of February), was evaluated for use as winter grazing for the overwintering of weaner steers in the Sour Sandveld of KwaZulu-Natal.
