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 ...

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 ...

Alien species that are present in national parks. See Spear et al. 2011 Koedoe

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. ...

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 ...

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 ...

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 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 ...

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 ...
