Arthropod and plant diversity in maize agro-ecosystems of South Africa
(North-West University (South Africa), Potchefstroom Campus, 2017)Agricultural intensification in the twentieth century has led to rapid biodiversity decreases on farmland. In sub-Saharan Africa, where rapid population increases and high direct dependence on natural resources coincide, ... -
Arthropod and plant diversity of maize agro–ecosystems in the grassland and savanna biomes of South Africa
(2014)Maize (Zea mays L.) is the most important grain crop in the country. Approximately 12 million tons of maize grain is produced annually on approximately 2.5 million ha of land. However, increased farming intensity can lead ... -
A comparison of bioinformatic workflows for herbivore dietary analysis using a DNA metabarcoding approach
(North-West University (South Africa), 2023)Dietary analysis based on faecal DNA metabarcoding is dependent on the taxonomic coverage and quality of records available in DNA barcode reference databases, as well as the subsequent choice of bioinformatics pipeline to ... -
Drought effects on the herbaceous community structure of transformed Mopaneveld
(North-West University (South Africa), 2020)Semi-arid Mopaneveld vegetation structure is driven by herbivory, fire, nutrients and rainfall variability. The floristically homogenous herbaceous layer is highly dynamic and dominated by forbs. Forb species contribute ... -
Herbaceous species diversity, redundancy and resilience of Mopaneveld across different land-uses
(North-West University (South Africa), 2016)Savanna ecosystems are under increasing arthropogenic pressure. In semi-arid Mopaneveld, few studies have aimed to quantify and evaluate the extent to which anthropogenic disturbances affect plant diversity and function ... -
Myth-busting tropical grassy biome restoration
(Wiley, 2020)The historical focus in research and policy on forest restoration and temperate ecosystems has created misunderstandings for the restoration of tropical and subtropical old‐growth grassy biomes (TGB). Such misconceptions ... -
Observations of ozone formation in southern African savanna and grassland fire plumes
(Elsevier, 2020)Open biomass burning is one of the largest sources of aerosols and reactive trace gases into the atmosphere, having a significant effect on earth's radiative budget and air quality. Biomass burning degrades air quality by ... -
One savanna, many shapes: how bush control affects the woody layer in the southern Kalahari
(Elsevier, 2019)Bush thickening (shrub encroachment) is a major ecological and economic threat in southern African savannas. Different types and intensities of bush control (BC) are applied to counteract and mitigate bush thickening. ... -
Plant and arthropod diversity of maize agro–ecosystems in the Highveld and Lowveld regions of South Africa
(North-West University, 2011)Surveys of plant and selected insect species was conducted in Highveld and Lowveld agro–ecosystems of four provinces of South Africa, namely North–West, Mpumalanga, KwaZulu–Natal and Limpopo. The objectives of the study ... -
Plant functional types differ between the grassland and savanna biomes along an agro-ecosystem disturbance gradient in South Africa
(Elsevier, 2017)Intensive, large-scale cultivation of food crops has led to major biodiversity loss worldwide due to fragmentation and degradation of remnant semi-natural habitat within agro-ecosystems. The response of vegetation to these ...
