Climate change and invasion impacts in the sub-Antarctic
Climate change and biological invasions are major threats to biodiversity. In particular, these threats are predicted to influence terrestrial systems in the sub-Antarctic, where significant ecosystem responses to both ...
Physiological tolerances and future distributions of two malaria vectors, Anopheles arabiensis and Anopheles funestus
Data collected was for two African malaria vectors, Anopheles arabiensis and Anopheles funestus. It includes information on thermal tolerance variables (CT and LT data) and information on development rate temperature ...
Molecular ecology of two invasive legumes (Acacia saligna and Paraserianthes lophantha)
Large-scale human-mediated movements of organisms promote the establishment of species outside their native ranges and a very small proportion of these species become invasive. Invasive species management typically assumes ...
Examining the relative contributions of latitudinal variation and phenotypic plasticity to thermal tolerance in arthropods
Climate change is one of the greatest challenges facing biodiversity today. To understand the responses of ectothermic organisms to increasingly variable climates, it is essential that we understand the patterns of variation ...
Opportunities and constraints in the restoration of riparian ecosystems invaded by alien trees: insights from the Western Cape, South Africa
Invasive alien species are widely considered to be the second most significant threat to biodiversity globally following direct habitat destruction. The invasion of riparian systems worldwide by alien plants has contributed ...
On the implementation effectiveness and efficiency of ecological interventions in operational contexts : the case of Working for Water
This data set was developed to estimate the factors that best predict the cost-effectiveness of Working for Water treatments in the Kouga and Krom project areas. See thesis and publication for details about the study.
The invasive ant Pheidole megacephala on an oceanic island: impact, control and community-level response to management
Alien invasive species are among the most important global conservation threats. Their management is one of the key conservation challenges that will have to be addressed in the next few decades. The study of real invasions ...
Effects of biotic resistance and resource availability on the invasion success of the Argentine ant, Linepithema humile (Mayr), in the Cape Floristic Region, South Africa.
The invasive Argentine ant, Linepithema humile, is widespread and has been introduced into the Cape Floristic Region (CFR) of South Africa. It has successfully established and spread into both urban and natural environments. ...
Assessing the interaction between history of usage and plant invasions: Bamboo as a case study
Studies in invasion science often focus on the biological or environmental implications of invasive alien species. However, biological invasions are inherently due to the human-mediated dispersal of species; this means ...
Barriers to ecosystem restoration after clearing invasive Acacia species in the South African fynbos: soil legacy effects, secondary invaders and weedy native species
A significant proportion of the world’s ecosystems are invaded by alien N2-fixing woody species such as Australian acacias. Invasive alien N2-fixing woody species often transform ecosystems through their negative impacts ...
