Delayed biodiversity change: no time to waste
(Elsevier Ltd., 2015)Delayed biodiversity responses to environmental forcing mean that rates of contemporary biodiversity changes are underestimated, yet these delays are rarely addressed in conservation policies. Here, we identify mechanisms ... -
Developing a framework of minimum standards for the risk assessment of alien species.
(British Ecological Society, 2018)1. Biological invasions are a threat to biodiversity, society and the economy. There is an urgent need to provide evidence-based assessments of the risks posed by invasive alien species (IAS) to prioritize action. Risk ... -
Developing a species selection index for seed-based ecological restoration in Peninsula Shale Renosterveld, Cape Town
(Elsevier B.V., 2015)The considerable risk factors associated with ecological restoration make the reintroduction of appropriate species critical to restoration success. In seed-based restoration efforts, using high quality seed is central to ... -
Disease outbreaks among penguins at sub-Antarctic Marion Island: a conservation concern
(An International Peer-Reviewed Journal of Seabird Science and Conservation, 2009)In 1992 and 1993, unknown diseases killed 250–300 King Penguins Aptenodytes patagonicus and an estimated 5–10 thousand Macaroni Penguins Eudyptes chrysolophus at sub-Antarctic Marion Island. At the same island, an outbreak ... -
Disentangling the abundance–impact relationship for invasive species
(2019)To predict the threat of biological invasions to native species, it is critical that we understand how increasing abundance of invasive alien species (IAS) affects native populations and communities. The form of this ... -
Disentangling the roles of environment and space in ecology

Diversity of bats in the Soutpansberg and Blouberg Mountains of northern South Africa: complementarity of acoustic and non-acoustic survey methods
(Southern African Wildlife Management Association, 2013-04)We surveyed bats at 30 localities in the Soutpansberg and Blouberg Mountains within the newly proclaimed Vhembe Biosphere Reserve (VBR) of northern South Africa, based on ANABAT acoustic recordings (63 nights) conducted ... -
Diversity, biogeography and the global flows of alien amphibians and reptiles
(John Wiley & Sons Ltd, 2017)Aim: We introduce a high-quality global database of established alien amphibians and reptiles. We use this data set to analyse: (1) the global distribution; (2) the temporal dynamics; (3) the flows between native and ... -
Dopluise (Hemiptera: Coccoidea) geassosieer met die wepstertmier, Crematogaster peringueyi Emery (Hymenoptera: Formicidae).
(AOSIS OpenJournals, 2015)Neste van die wipstertmier, Crematogaster peringueyi (Hymenoptera: Formicidae), is op verskeie plekke langs die kus van die Wes-Kaap versamel. Die doel was om vas te stel watter dopluisagtiges (Hemiptera: Coccoidea) in ... -
Drivers of compositional dissimilarity for native and alien birds: the relative roles of human activity and environmental suitability
(2020)We assessed the relative importance of human activity and environmental suitability as drivers of compositional dissimilarity of alien birds for 65 of the most populous cities of the Iberian Peninsula. We examined how these ... -
Drivers of the relative richness of naturalized and invasive plant species on Earth
(2019)Biological invasions are a defining feature of the Anthropocene, but the factors that determine the spatially uneven distribution of alien plant species are still poorly understood. Here, we present the first global analysis ... -
E-commerce trade in invasive plants
(Society for Conservation Biology, 2015)Biological invasions are a major concern in conservation, especially because global transport of species is still increasing rapidly. Conservationists hope to anticipate and thus prevent future invasions by identifying and ... -
Ecological niche modeling of the invasive potential of Nile tilapia Oreochromis niloticus in African river systems: concerns and implications for the conservation of indigenous congenerics
(2013-06-30)This study applied ecological niche models to determine the potential invasive range of Nile tilapia, Oreochromis niloticus, with a particular focus on river systems in southern Africa where it is now established and ... -
Ecological niche modelling of an invasive alien plant and its potential biological control agents
(Elsevier B.V., 2010)Invasive alien plants are of concern in South Africa. Pompom weed (Campuloclinium macrocephalum) is currently invading the Grassland and Savannah biomes of South Africa and is likely to continue spreading in the southern ... -
Ecological niche modelling of an invasive alien plant and its potential biological control agents
(Elsevier B.V., 2011)Invasive alien plants are of concern in South Africa. Pompom weed (Campuloclinium macrocephalum) is currently invading the Grassland and Savannah biomes of South Africa and is likely to continue spreading in the southern ... -
Emerging ornamental plant invaders in Urban Areas – Centranthus ruber in Cape Town, South Africa as a case study
(Weed Science Society of America, 2017)Plant species that receive significant human introduction effort and assistance generally are the most problematic invaders. Despite this, invasive ornamental species in urban settings have received relatively little ... -
Encompassing the relative non-target risks from agents and their alien plant targets in biological control assessments
(Springer, 2016)Criticisms about the safety of biological control of alien plants has resulted in a risk-averse approach, where the risks posed by the agent are paramount and the risks posed by the alien plant are neglected. We argue ... -
Ethical considerations for field research on fishes
(AOSIS, 2016)Collection of data from animals for research purposes can negatively impact target or by-catch species if suitable animal ethics practices are not followed. This study aimed to assess the ethical requirements of peer-reviewed ... -
Eucalyptus invasions in riparian forests: Effects on native vegetation community diversity, stand structure and composition.
(Elsevier B.V., 2013)Effects of alien plant invaders on native ecosystems are widely acknowledged, although the evidence is sometimes speculative, especially in riparian zones. We examined the changes in floristic diversity, stand structure ...
