Reintroduction of Spotted Hyena (Crocuta crocuta) Within Their Former Range: A Home Range Establishment Case Study in Tswalu Kalahari Reserve

Haemish Melville, Nichola M. Knox

Top predators drive ecosystem functions. Reintroductions of top predators are a vital conservation management strategy to achieve this. Ten spotted hyenas (hyenas—Crocuta crocuta) were reintroduced to the Tswalu Kalahari Reserve (TKR). To determine how hyenas recolonised the TKR, we fitted five hyenas …

Soil Organic Carbon Heterogeneity: Insights from Hyperlocal and Field-Scale Sampling

Christopher Charles Lakey, Nichola M. Knox, Jacqueline McGlade

The organic carbon content of soil is of increasing global interest. Soil is the largest terrestrial store of carbon on the planet, yet many agricultural soils are highly degraded, and a significant source of greenhouse gas emissions. However, appropriate management can mitigate …

Remote monitoring of Soil Health: Insights into the impacts of biomineralization applications to build soil health

Nichola M. Knox, Jacqueline McGlade, Christopher Charles Lakey, Kym Kruse et autres

Soils are the largest terrestrial carbon store on the planet. However, it is estimated that soils have lost 8% of their carbon content since human farming began. Around the world, agricultural soils are highly degraded and are a significant source of greenhouse …

Quantifying unseen woody biomass and diversity in understorey trees and shrubs at the extremes of water availability in the Miombo ecoregion

Hermane Diesse, John L. Godlee, Nichola M. Knox, Jonathan Ilunga Muledi et autres

The Miombo ecoregion covers eastern and southern Africa, with variations in plant species composition, structure, and biomass across a broad precipitation gradient. Most studies of woody plant communities focus exclusively on larger overstorey trees (≥5 or ≥10 ​cm stem diameter), overlooking the …

Spatio-Temporal Transferability of Drone-Based Models to Predict Forage Supply in Drier Rangelands

Vistorina Amputu, F. A. Männer, Katja Tielbörger, Nichola M. Knox

Unmanned aerial systems offer a cost-effective and reproducible method for monitoring natural resources in expansive areas. But the transferability of developed models, which are often based on single snapshots, is rarely tested. This is particularly relevant in rangelands where forage resources are …

An overview of the ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) project: aerosol–cloud–radiation interactions in the southeast Atlantic basin

Jens Redemann, Robert Wood, Paquita Zuidema, Sarah J. Doherty et autres

Southern Africa produces almost a third of the Earth's biomass burning (BB) aerosol particles, yet the fate of these particles and their influence on regional and global climate is poorly understood. ORACLES (ObseRvations of Aerosols above CLouds and their intEractionS) is a …

Mapping and Monitoring Fractional Woody Vegetation Cover in the Arid Savannas of Namibia Using LiDAR Training Data, Machine Learning, and ALOS PALSAR Data

Konrad Wessels, Renaud Mathieu, Nichola M. Knox, Russell Main et autres

Namibia is a very arid country, which has experienced significant bush encroachment and associated decreased livestock productivity. Therefore, it is essential to monitor bush encroachment and widespread debushing activities, including selective bush thinning and complete bush clearing. The aim of study was …
