About the binomen Cylindropuntia rosea (Cactaceae) and its invasive individuals recorded in the Valencian Community (Spain)
(2013)Cylindropuntia rosea (DC.) Backeb., a name often used to designate the ‘Cardenche’ invasive cactus in the Valencian Community (Spain) is a misapplied binomen in many botanical works. The plants referred under this combination ... -
ABSTRACT: Acacia saligna’s soil legacy effects persist longer than ten years after clearing
(Elsevier B.V., 2017) -
Adaptive rather than non-adaptive evolution of Mimulus guttatus in its invasive range
(Elsevier GmbH, 2008)Adaptive and non-adaptive evolutionary processes are likely to play important roles in biological invasions but their relative importance has hardly ever been quantified. Moreover, although genetic differences between ... -
Advancing impact prediction and hypothesis testing in invasion ecology using a comparative functional response approach
(Springer, 2014-04)Invasion ecology urgently requires predictive methodologies that can forecast the ecological impacts of existing, emerging and potential invasive species. We argue that many ecologically damaging invaders are characterised ... -
Alien species in National Parks Database
(2012-03-07)Alien species that are present in national parks. See Spear et al. 2011 Koedoe -
Angling baits and invasive crayfish as important trophic subsidies for a large cyprinid fish
(Springer, 2015)Invasive species and anthropogenic sources of allochthonous trophic subsidies can have substantial ecological consequences for freshwater ecosystems, including modifying the diet of consumers and altering food web structure. ... -
Animal introductions to southern systems: lessons for ecology and for policy
(Zoological Society of Southern Africa, 2009-10)Numerous animal species have been introduced to areas from which they were previously absent, and many of these have become invasive, with substantial impacts. However, in other cases, impacts are assumed from theory. ... -
Animals in parks database
(2012-03-07)A database of animals in national parks in South Africa, their potential impacts and possible pathways of introduction. There is severity of impact information for a subset of species considered to be those species with ... -
Ant assemblages have darker and larger members in cold environments
(John Wiley & Sons Ltd, 2016)Aim In ectotherms, the colour of an individual’s cuticle may have important thermoregulatory and protective consequences. In cool environments, ectotherms should be darker, to maximize heat gain, and larger, to minimize ... -
Anti-predator strategies of the invasive African clawed frog, Xenopus laevis, to native and invasive predators in western France (dataset)
When species are translocated to a novel environment, individuals become exposed to new predators against which they may not express very efficient defences at least at an initial stage. The strength of anti-predator defence ... -
Are native cyprinids of introduced salmonids stronger regulators of benthic invertebrates in South African headwater streams?
(Ecological Society of Australia, 2016)The introduction of nonnative salmonids in the Southern Hemisphere generally leads to a reduction in invertebrate abundance and changes in assemblage composition. In the Cape Floristic Region of South Africa, introduced ... -
Assessing the distribution of the Argentine ant using physiological data
(Elsevier Masson SAS, 2009)To address the lack of physiological approaches in current models assessing the potential distribution of the Argentine ant, we used data on brood development from distinct sources to evaluate a series of degreeday models ... -
An assessment of the effectiveness of a long-term ecosystem restoration project in a fynbos shrubland catchment in South Africa
(Elsevier Ltd., 2017)The long-term effectiveness of ecological restoration projects is seldom reported in the scientific literature. This paper reports on the outcomes of ecosystem restoration following the clearing of alien Pinus plantations ... -
The balance of trade in alien species between South Africa and the rest of Africa
(AOSIS, 2017)Background: Alien organisms are not only introduced from one biogeographical region to another but also spread within regions. As South Africa shares land borders with six countries, multiple opportunities exist for the ... -
The (bio)diversity of science reflects the interests of society
(2007)For ecologists to develop robust generalizations and principles, a broad taxonomic and geographic spread of research is required, but, in practice, most generalizations are based on the research of individual scientists ... -
The BIOTA Observatories
(Klaus Hess Publishers, 2010)The BIOTA Southern Africa transects (Fig. 1, on left side) have been designed to describe biodiversity changes in space and time along two major climatic gradients in the western part of southern Africa (see also ... -
Born to kill: Predatory functional responses of the littoral amphipod Echinogammarus marinus Leach throughout its life history
(Elsevier, 2012)Studies of predator–prey interactions, and in particular the derivation of functional responses, have typically focussed on adults or single life-history stages, with subsequent food web analyses often simply using average ... -
Carbohydrates in cyanobacterial soil crusts as a source of carbon in the southwest Kalahari, Botswana
(2010)Semiarid ecosystems, also known as drylands, contain small amounts of carbon (C). To date only few studies have evaluated soil C dynamics in these ecosystems. Cyanobacterial soil crusts are considered a major source of ... -
