Urban areas confront a number of environmental issues including excessive thermal stress
and concentrated emissions of greenhouse gases and pollutants. In past decades, many …

The rapid expansion of urban areas worldwide is leading to native habitat loss and
ecosystem fragmentation and degradation. Although the study of urbanisation's impact on …

The genus Eucalyptus is native to Australia and Indonesia but has been widely planted in
many countries. Eucalyptus has proven to be particularly successful in tropical and …

The purpose of this paper is to review studies relevant to potential climate change impacts
on natural stands of eucalypts, with a view to identifying not only specific lessons for the …

Recent work suggests that hydraulic mechanisms, rather than cambium necrosis, may
account for rapid post‐fire tree mortality. We experimentally tested for xylem cavitation, as a …

Speciation is a complex process that is fundamental to the origins of biological diversity.
While there has been considerable progress in our understanding of speciation, there are …

We investigated the type and extent of degradation at three sites on the Agulhas Plain,
South Africa: an old field dominated by the alien grass Pennisetum clandestinum …

Eucalypt species have several features that make them particularly well suited for climate
change studies. A key assumption is that they have very limited powers of dispersal. If this is …

Gum trees, or eucalypts (Eucalyptus species), have been targeted for invasive alien plant
clearing programmes in many parts of South Africa. This has caused some dissatisfaction …

Animals that forage for food or dig burrows by biopedturbation can alter the biotic and abiotic
characteristics of their habitat. The digging activities of such ecosystem engineers, although …
