Ecological impacts of alien species: Quantification, scope, caveats, and recommendations
(Oxford University Press, 2015)Despite intensive research during the past decade on the effects of alien species, invasion science still lacks the capacity to accurately predict the impacts of those species and, therefore, to provide timely advice to ... -
Ecological impacts of invasive alien species along temperature gradients: testing the role of environmental matching
(Ecological Society of America, 2015)Invasive alien species (IAS) can cause substantive ecological impacts, and the role of temperature in mediating these impacts may become increasingly significant in a changing climate. Habitat conditions and physiological ... -
The ecological integrity of the lower Olifants River, Limpopo province, South Africa: 2009-2015-Part B: Tributaries of the Olifants River
(Taylor & Francis, 2017)Monitoring on the Lowveld reaches of the Olifants River, Limpopo River System, and its Steelpoort, Blyde, Klaserie and Selati tributaries was initiated in 2009. Analysis of the 2009–2015 data from four Olifants River sites ... -
The ecological integrity of the Lower Olifants River, Limpopo province, South Africa: 2009-2015-Part A: Olifants River main stem
(Taylor & Francis, 2017)The major rivers of the South African ‘Lowveld’ (low-latitude savanna) suffer numerous impacts from upstream economic activities. Whereas monitoring these rivers is required to detect biodiversity losses, record ... -
Ecological niche differentiation of polyploidization is not supported by environmental differences among species in a cosmopolitan grass genus
(Botanical Society of America, 2015)• Premise of the study: Polyploidization frequently results in the creation of new plant species, the establishment of which is thought to often be facilitated by ecological niche differentiation from the diploid species. ... -
The ecology of Bactrocera tryoni (Diptera: Tephritidae): what do we know to assist pest management?
(Association of Applied Biologists, 2011)The distribution, systematics and ecology of Bactrocera tryoni, the Queensland fruit fly, are reviewed. Bactrocera tryoni is a member of the B. tryoni complex of species, which currently includes four named species, viz. ... -
The effects of intransitive competition on coexistence
(John Wiley & Sons Ltd/CNRS, 2017)Coexistence theory has been developed with an almost exclusive focus on interactions between two species, often ignoring more complex and indirect interactions, such as intransitive loops, that can emerge in competition ... -
The effects of temperature, body mass and feeding on metabolic rate in the tsetse fly, Glossina morsitans centralis
(2007)Metabolic rate variation with temperature, body mass, gender and feeding status is documented for Glossina morsitans centralis . Metabolic rate [mean ± SE; VCO2 = 19.78 ± 3.11 uL CO 2 h −1 in males (mean mass = 22.72 ± ... -
Emergence of weak-intransitive competition through adaptive diversification and eco-evolutionary feedbacks
(British Ecological Society, 2018)1. Indirect biotic interactions—such as intransitive competition—are increasingly recognized as being important in shaping ecological patterns in natural systems. Over long time-scales, such indirect interactions may ... -
Evaluation of the soil degradation state along fence-line contrasts
(Klaus Hess Publishers, 2010)Five pairs of Observatories with contrasting landuse types and/ or landuse intensities, located in the Woodland Savanna, Thornbush Savanna, Nama Karoo, and Succulent Karoo biomes were investigated to examine the infl ... -
Evidence for diet partitioning among three coexisting native freshwater fishes in South Africa's Cape Fold Ecoregion
(NISC (Pty) Ltd, 2018)The partitioning of limited resources commonly explains how different species can coexist within the same ecological community. In this 2010 study, the diets of three coexisting freshwater fishes (Cape galaxias Galaxias ... -
Evidence for freedom from swine influenza in a remote area of Northern Vietnam
(Elsevier, 2012)Swine influenza is responsible for one of the most prevalent disease affecting the swine industry worldwide. Epidemiological surveys rarely focus on remote areas, because traditional farming systems characterized by ... -
Evolution of fast-growing and more resistant phenotypes in introduced common mullein (Verbascum thapsus)
(British Ecological Society, 2013)1. Species introduced into areas outside of their native range face novel biotic and abiotic conditions, which probably impose novel selection pressures. Adaptation to these new conditions may increase the ability of ... -
The extent and impacts of ungulate translocations: South Africa in a global context
(Elsevier Ltd., 2009)Despite the apparent risks of the introduction of non-indigenous ungulates to biodiversity, relatively little is known globally about the pathways of introduction, propagule pressure and realized impacts of ungulate ... -
Extracellular polysaccharides from cyanobacterial soil crusts: A review of their role in dryland soil processes
(Elsevier Ltd., 2011)Cyanobacterial soil crusts are a community of microorganisms living in the soil surface of different habitats worldwide. Through photosynthesis, cyanobacteria produce extracellular polysaccharides (EPS) increasing the soil ... -
Fine-scale invasion genetics of the quarantine pest, Anoplophora glabripennis, reconstructed in single outbreaks
(2019)The xylophagous cerambycid Anoplophora glabripennis, the Asian long-horned beetle (ALB), is highly polyphagous and can colonize a wide range of broadleaved host trees causing significant economic damage. For this reason, ... -

Flammability of the keystone savannah bunchgrass Aristida stricta
(Springer, 2016)Understanding the flammability of species in fire-prone or fire-dependent ecosystems is necessary for modeling and predicting ecosystem dynamics. Wiregrass (Aristida stricta syn. A. beyrichiana), a keystone perennial ...
