Field-scale calibration of the PAR Ceptometer and FieldScout CM for real-time estimation of herbage mass and nutritive value of rotationally grazed tropical pasture

Smart Agricultural Technology, 2022
Destructive sampling method is regarded as the standard approach for evaluating pasture herbage. However, non-destructive methods for managing pastures are rapidly gaining acceptance because they provide faster results that can influence real-time ...

How Energetic Demands and Habitat Utilisation Can Make or Break Giraffes

African Journal of Ecology, Volume 63, Issue 8, December 2025.
ABSTRACT Understanding how large herbivores balance energy intake and expenditure is critical for effective rangeland management and conservation. Giraffes (Giraffa camelopardalis), as selective browsers, depend on high‐quality forage resources that vary seasonally, influencing their movement patterns, home range and habitat selection.

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 ...
