Amphibian diversity and breeding behaviour in the Okavango Delta
(North-West University, 2010)Amphibians are of great ecological importance and a loss of species will have widespread and dire consequences. Recent population declines and extinctions have resulted in amphibians being labelled the most threatened ... -
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 ... -
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 ... -
Drought responses of forb and grass communities in communal and protected rangelands
(North-West University (South Africa). Potchefstroom Campus, 2019)The structure, growth, dynamics and productivity of herbaceous vegetation in semi-arid savannas are strongly limited by rainfall variability and nutrient availability. These factors interact with other drivers of savanna ... -
The effect of urbanization and agriculture on predacious arthropod diversity in the Highveld grasslands
(2015)Biodiversity provides vital ecosystem services and more diverse ecosystems are known to be more stable and resilient in the face of disturbance. Predacious arthropods provide a valuable ecosystem service to control pest ... -
Potential of Oecophylla longinoda (Hymenoptera: Formicidae) for management of Helopeltis spp. (Hemiptera: Miridae) and Pseudotheraptus wayi (Hemiptera: Coreidae) in cashew in Tanzania
(North-West University, 2013)Cashew, Anacardium occidentale Linnaeus, is an economically important cash crop for more than 300,000 rural households in Tanzania. Its production is, however, severely constrained by infestation by sap-sucking insects ... -
Taxonomy of the rectal endociliates of Xenopus laevis (Anura)
(North-West University (South Africa), 2023)Amphibians are hosts to a variety of parasite groups which include protozoans, cestodes, nematodes, acanthocephalans, monogenetic flukes, digenetic flukes, and mites. Nevertheless, of these parasite groups infecting ... -
Vegetation establishment and functionality on kimberlite tailings in the afro-alpine zone of Lesotho
(North-West University (South Africa), 2017)Mining activities can have severe negative impacts on the natural environment. It is therefore important for mines to develop and implement mitigation measures through a rehabilitation strategy. As such, Letšeng Diamond ... -
Weed profiling fields of herbicide tolerant maize in the Mthatha region, Eastern Cape Province
