Chilean needle grass (Nassella neesiana) is highly invasive in temperate native grasslands of south-eastern Australia. Its impact on plant biodiversity was quantified by assessing foliar cover and species diversity of other vascular plants inside, on the margins of, and outside N. neesiana patches...

The introduction and establishment of non-native species has been recognized as one of the most significant threats to the maintenance of native biodiversity in most taxa, including angiosperms. The Siberian peashrub, Caragana arborescens Lam. (Fabaceae), is native to Eurasia, but was introduced to ...

Chromolaena odorata (L.) King & Robinson (Asteraceae), an invasive alien plant of terrestrial habitat in many tropical and sub-tropical regions of the world, was investigated in the South-West Ecological Zone of Nigeria. Investigations, including field observations on C. odorata and a survey of...

Invasive alien plant species (IAPS) are one of the biggest threats to biodiversity in several last and suppose to be during next few decades. All their activities (introduction, dispersal, spreading) are directly and indirectly connected with human activities. Some of these impacts are hardly to be ...

This paper aims to highlight the direct and indirect allelopathic influences showed by species Ailanthus altissima, through morphological and biological investigations. An important factor in the success of Ailanthus species invasion is the release of allelopathic compounds that influence...

Invasive alien plants impact negatively on agriculture, forestry, natural ecosystems, human health, and biodiversity. These global threats also apply to South Africa, which basically is a water-stressed country that cannot afford wastage of water by any means, least of all through alien invasive...

In 2004 the Australian Government officially recognised the significance of climate change on exotic species management (both weeds and pest animals) and biodiversity conservation, with the release of the National Action Plan for Biodiversity and Climate Change (NRMMC 2004). In order to meet the...

The New Zealand flatworm, Arthurdendyus triangulatus, is an invasive alien species (IAS) that is of concern because it predates earthworms. The impacts of depleted earthworm populations affect both agriculture and biodiversity, through a decline in soil fertility and a reduction in...

Alien plants or weeds are acknowledged as a significant cause of global biodiversity decline. However, limited quantitative data is available on the biodiversity threatened by weeds. While there have been numerous studies of the impacts on individual native species, they do not allow for broad...
