Produção de forragem e potencial de utilização do capim faixa-branca submetido a frequências de desfolhação

Arquivo Brasileiro de Medicina Veterinária e Zootecnia
RESUMO O objetivo deste trabalho foi avaliar a produção de forragem e o potencial de utilização do capim faixa-branca submetido a frequências de desfolhação. Os tratamentos foram constituídos de quatro frequências de desfolhação: muito alta (25cm), alta (

The Woody Invasive Plant Neltuma juliflora Influences Plant Species Richness and Soil Chemistry in Botswana

Journal of Vegetation Science, Volume 36, Issue 5, September/October 2025.
We explored the plant species composition and soil physicochemical properties of plots with and without the invasive woody species Neltuma juliflora in Gantsi District Botswana. Presence of N. juliflora was associated with lower species diversity, lower plant density and increased soil cation exchange capacity and total nitrogen.

Woody and Herbaceous Species Diversity Respond Differently to Environmental Variables in Semiarid Areas in Ghana

Ecology and Evolution, Volume 15, Issue 4, April 2025.
In the drylands of Ghana, the relative importance of various environmental drivers for plant species composition and diversity is still poorly understood and this affects the identification and implementation of appropriate management strategies.

Assessment of Vegetation Habitat Types and Characteristics of Potential Nesting Trees for White‐Backed Vultures (Gyps africanus) in Kempiana and Manyeleti Nature Reserves, Mpumalanga Province, South Africa

Ecology and Evolution, Volume 15, Issue 3, March 2025.
The study revealed that Scavenger Vultures (Gyps africanus) prefer to nest in mixed forests with grass rather than in grasslands, bare ground, or built‐up environments. They also choose tall, wide trees. These results confirm that these vultures do not choose their nesting trees at random, but according to specific criteria.

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 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
