Exploring meaningful nature experience, connectedness with nature and the revitalization of transformative education for sustainability
This study brings together four core themes: connectedness with nature (CWN), invasive alien species (IAS), and education for sustainability (EfS); each of which are explored around - and in relationship to - the core ...
Invasive woody plants: a double-edged sword for invertebrate conservation
While the Cape Peninsula (South Africa) is renowned for its exceptional plant and invertebrate diversity and endemism, extensive alien plant invasion and exotic pine plantations reduce native species richness, and may ...
Thermal tolerance responses to environmental variability in insect models
Organisms are able to respond to their changing environment, and the extent of the response is thought to depend on the degree of variability and predictability of the environment. Furthermore, the form of this physiological ...
Comparative Impact of Invasive Alien Trees and Vineyards on Arthropod Diversity in the Cape Floristic Region, Western Cape
Invasive alien trees (IATs) and agriculture are rapidly altering the capacity of ecosystems to provide a variety of essential services, with decreasing habitat quality having an adverse effect on arthropod biodiversity. ...
Alien invaders and reptile traders: risk assessment and modelling of trends, vectors and traits influencing introduction and establishment of alien reptiles and amphibians
Biological invasions are a growing threat to biodiversity, trade and agriculture in South Africa. Though alien reptiles and amphibians (herpetofauna or herps) are not currently a major threat, escalating problems worldwide ...
Invasive potential of the Peruvian pepper tree (Schinus molle) in South Africa
We investigated the potential of an invasive alien tree to transform vegetation by quantifying the relative abilities of the alien tree Schinus molle and dominant native trees Acacia tortilis and Rhus lancea to compete for ...
Soil type, microsite, and herbivory influence S.molle growth
The study involved a field manipulation experiment over 14 months using a factorial block design to examine transplanted seedlings in different savanna environments. The experiments examine the effects of soil type (sandy ...
Megastigmus wasp damage to seeds of Schinus molle
Understanding the reasons why some alien species become invasive may help to identify appropriate management strategies. One hypothesis often cited to explain invasion success is the enemy release hypothesis (Williams 1954; ...
Alien species and propagules in the Antarctic: movements though space and time
Although the impacts of biological invasions are widely appreciated, a bias exists in research effort to post-dispersal processes because of the difficulties of measuring propagule pressure and the detecting of newly ...
Project files consist of numeric data above-ground vegetation attributes, soil-stored seed bank, soil physico-chemical properties collected in the Berg River, Western Cape, South Africa
