Why do models of insect respiratory patterns fail?
(Company of Biologists, 2018)Insects exchange respiratory gases using an astonishing diversity of patterns. Of these, discontinuous gas exchange cycles (DGCs) have received the most study, but there are many other patterns exhibited intraspecifically ... -
Insect-flower interaction networks vary among endemic pollinator taxa over an elevation gradient
(Public Library of Science, 2018-11-29)Interaction networks are sensitive to elevation gradients through changes in local distribution of interacting partners. Here, we use plant-pollinator interaction network metrics to assess the effect of elevation on flowers ... -
Artificial reservoirs complement natural ponds to improve pondscape resilience in conservation corridors in a biodiversity hotspot
(Public Library of Science, 2018-09-20)Natural ponds are rich in biodiversity, contributing greatly to regional aquatic biodiversity. Artificial reservoirs used for irrigation can be significant additional features of the landscape. They infill the local natural ... -
Only multi-taxon studies show the full range of arthropod responses to fire
(Public Library of Science, 2018-04-03)Fire is a major driver in many ecosystems. Yet, little is known about how different ground-living arthropods survive fire. Using three sampling methods, and time-since-fire (last fire event: 3 months, 1 year, and 7 years), ... -
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, ... -
New policy directions for global pond conservation
(Wiley Open Access, 2018)Despite the existence of well‐established international environmental and nature conservation policies (e.g., the Ramsar Convention and Convention on Biological Diversity) ponds are largely missing from national and ... -
Increase anti-poaching law-enforcement or reduce demand for wildlife products? A framework to guide strategic conservation investments
(Wiley Open Access, 2018)Donors, NGOs, and governments increasingly invest in campaigns to reduce con-sumer demand for wildlife products in an attempt to prevent the decline of overex-ploited and poached species. We provide a novel framework to ... -
Traditional medicinal animal use by Xhosa and Sotho communities in the Western Cape Province, South Africa
(BMC (part of Springer Nature), 2019-07-09)Background: The use of animals and animal-derived materials in traditional medicine constitutes an important part of the belief systems of indigenous African cultures. It is believed to be rapidly expanding in South Africa, ... -

(International Mycological Association, 2018-12-01)This genome announcement includes draft genomes from Claviceps purpurea s.lat., including C. arundinis, C. humidiphila and C. cf. spartinae. The draft genomes of Davidsoniella eucalypti, Quambalaria eucalypti and Teratosphaeria ... -
Knoxdaviesia proteae is not the only Knoxdaviesia-symbiont of Protea repens
(International Mycological Association, 2015-11-10)Two polyphyletic genera of ophiostomatoid fungi are symbionts of Proteaceae in southern Africa. One of these, Knoxdaviesia, includes two closely related species, K. proteae and K. capensis, that have overlapping geographical ... -
Seed survival of Australian Acacia in the Western Cape of South Africa in the presence of biological control agents and given environmental variation
(PeerJ, 2019)Studies of invasive Australian Acacia have shown that many seeds are still produced and accumulate in soil stored seed banks regardless of the presence of seed-targeting biological control agents. This is despite claims ... -
Edible fynbos plants : a soil types and irrigation regime investigation on Tetragonia decumbens and Mesembryanthemum crystallinum
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Fynbos’ rich biodiversity has been a source of much economic activity with its beautiful wild flowers and world-famous Proteas. Additionally, the medicinal and health benefits of rooibos and honey bush ... -
Mapping the contours of organic agriculture : an exploratory study of an under-served population in South Africa
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: The aim of this study was to determine the challenges that organic producers face in South Africa and to determine how universities and other knowledge institutions might better support these producers. ... -
Examining the spatiotemporal dynamics of exotic plants in a montane grassland : mechanisms and management
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Despite a surge of research on exotic species in alpine habitats, a lack of reliable baseline data has inhibited long-term understanding about exotic species dynamics in mountain ecosystems across the ... -

(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: African elephants (Loxodonta africana) are megaherbivore mixed feeders. They are an important keystone species, influencing a variety of factors within an ecosystem. Historically elephants migrated ... -
Understanding social-ecological regime shifts : the case of woody encroachment in South Africa
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Humanity has been very successful in modifying the planet to meet the demands of a rapidly growing human population. As human activities have grown in magnitude, they have become increasingly interlinked ... -
Trimen’s false tiger moth, Agoma trimenii (Lepidoptera: Agaristidae) : biology and potential control options
(Stellenbosch : Stellenbosch University, 2019-04)ENGLISH ABSTRACT: Trimen’s false tiger moth, Agoma trimenii (Lepidoptera: Agaristidae), has developed pest status in vineyards in the Northern Cape and Limpopo (Groblersdal area) provinces of South Africa. Larvae feed on ... -
Invasive Australian Acacia seed banks: Size and relationship with stem diameter in the presence of gall-forming biological control agents
(Public Library of Science, 2017)Australian Acacia are invasive in many parts of the world. Despite significant mechanical and biological efforts to control their invasion and spread, soil-stored seed banks prevent their effective and sustained removal. ... -
Including irrigation in niche modelling of the invasive wasp Vespula germanica (Fabricius) improves model fit to predict potential for further spread
