(Pensoft Publishers, 2017)Global biodiversity faces many challenges, with the conservation of invertebrates among these. South Africa is megadiverse and has three global biodiversity hotspots. The country also employs two invertebrate-based rapid ... -
Foliar application of steinernema yirgalemense to control planococcus ficus : assessing adjuvants to improve efficacy
(South African Society for Enology and Viticulture, 2018)The vine mealybug (Planococcus ficus) is regarded as a key mealybug pest of grapevines in South Africa, with entomopathogenic nematodes (EPNs) being touted as a potential alternative to chemical control, although their ... -
Plant functional trait data and reflectance spectra for 22 palmiet wetland species
(Elsevier, 2018)We provide reflectance spectra for 22 South African palmiet wetland species collected in spring 2015 from three wetlands throughout the Cape Floristic Region. In addition, we provide summarized plant functional trait data, ... -
Potential of local entomopathogenic nematodes for control of the vine mealybug, planococcus ficus
(South African Society for Enology and Viticulture, 2018)Planococcus ficus, the vine mealybug, is the dominant mealybug pest of grapes in South Africa. To provide an alternative for chemical control, entomopathogenic nematodes (EPNs) were investigated as a biological control ... -
Woody encroachment as a social-ecological regime shift
(MDPI, 2018-06-28)African savannas are increasingly affected by woody encroachment, an increase in the density of woody plants. Woody encroachment often occurs unexpectedly, is difficult to reverse, and has significant economic, cultural ... -
Restoration potential of alien-invaded Lowland Fynbos
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: Widespread degradation of ecosystems on a global scale has led to the need for ecological restoration in order to more effectively conserve and manage threatened ecosystems. While this is an emerging ... -
Drought stress responses in wild and cultivated Aspalathus linearis of the Suid Bokkeveld, Northern Cape Province of South Africa : linkages between local knowledge and empirical evidence
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: The north-western region of the Western Cape forms part of the Fynbos biome and is home to the indigenous plant, A. linearis (rooibos). Rooibos cultivation is restricted to a small geographic area with ... -
Integrative taxonomy of the endemic Karoo agile grasshoppers, the Euryphyminae
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: The Euryphyminae are a small, African subfamily of grasshoppers which are not very well known. They are endemic to sub-Saharan Africa and consist of 23 genera, 16 of which have records of occurrence in ... -
Conservation of diverse parasitoid assemblages across agricultural mosaics within the Cape Floristic Region, South Africa
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: The ever-growing agricultural industry within the Cape Floristic Region (CFR) threatens many arthropod species, including functionally beneficial insects such as parasitoids. Damage caused by insect pests ... -
Transitioning to organic agriculture : the changes in arthropod biodiversity and pests over time
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: The Greater Cape Floristic Region (GCFR) is a unique area known for its incredible biodiversity. It is also the largest wine-grape producing area in South Africa. However, agriculture and more specifically ... -
Ring nematode (Criconemoides xenoplax), distribution, characterisation and culture methods
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: The ring nematode, Criconemoides xenoplax (Raski, 1952) Loof & De Grisse, is described as a migratory ectoparasitic nematode that feeds entirely on the roots of plants, mainly those of woody perennials. ... -
Mite (acari) ecology within protea communities in the Cape Floristic Region, South Africa
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: Protea is a key component in the Fynbos Biome of the globally recognised Cape Floristic Region biodiversity hotspot, not only because of its own diversity, but also for its role in the maintenance of ... -
Biologically based methods for pest management in agriculture under changing climates : challenges and future directions
(MDPI, 2012)The current changes in global climatic regimes present a significant societal challenge, affecting in all likelihood insect physiology, biochemistry, biogeography and population dynamics. With the increasing resistance of ... -
Ecosystem services of palmiet wetlands : the role of ecosystem composition and function
(Stellenbosch : Stellenbosch University, 2018-03)ENGLISH ABSTRACT: Ecosystems are the critical infrastructure that provides society with multiple essential services. A change from one land-use to another (e.g. wetlands to agriculture) may result in trade-offs, or ... -
Diversity and community structure of gastrointestinal helminths of Rhabdomys spp. and other small mammals in South Africa
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Descriptive information forms the basis for broader ecological questions and therefore plays a vital role in studies that explore patterns in parasite diversity, distribution and species assemblages. ... -
Ecology of apex predators in Majete Wildlife Reserve, Malawi.
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Apex carnivores play an important role in the ecosystem by regulating prey via predation. Anthropogenic influences have resulted in rapid range and population reductions of large carnivores across the ... -
Ecology of plains zebra (Equus quagga) in Majete Wildlife Reserve, Malawi
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Zebras occur throughout Africa and are responsible for sustaining the dynamics and overall well-being of the environments they reside in. However, zebras have experienced significant range reductions and ... -
Conservation of spider diversity within an agricultural mosaic : insights from the Greater Cape Floristic Region, biodiversity hotspot.
(Stellenbosch : Stellenbosch University, 2017-12)ENGLISH ABSTRACT: Agricultural expansion is one of the main drivers of habitat fragmentation and land use change which negatively impacts biological diversity. The Greater Cape Floristic Region (GCFR), a biodiverse hotspot, ... -
