The rampant spread of the invasive alien plant Parthenium hysterophorus (Asteraceae) in subtropical South Africa prompted research into biological control methods more than a decade ago. Parthenium impacts broadly on agriculture, biodiversity conservation and health. Elsewhere, significant control...

Hypericum androsaemum L. (tutsan) invades pastures and natural ecosystems in high rainfall areas of south-eastern Australia. The rust fungus Melampsora hypericorum was detected in Australia in 1991 and drastically reduced the extent of H. androsaemum populations in some areas. The impact of the...

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 ...

Among the Mediterranean countries, Turkey has the richest freshwater fish fauna. Turkey is located in the intersection of different zoogeographic regions and Anatolia is highly rich in terms of biodiversity. Freshwater fish fauna of Turkey consists of more than 350 species and about one-third of...

The current list of invasive and potentially invasive alien vascular plants in Bulgaria comprises 60 species. The selection of the taxa is not a result of strict criteria-based approach but it is based on the available literature data and field observations taking into account the current...

Dieback in invasive and agricultural plants is a common phenomenon attributed to a range of abiotic and biotic factors. In this project we are investigating the link between the introduction and establishment of a non-native plant to a new range and the subsequent dying-back of the invasive...

Mikania micrantha (Asteraceae) commonly known as mikania, is a major invasive alien plant (IAP) in the tropical humid agricultural and forest zones of the Asia-Pacific region. This fast-growing Neotropical vine is able to smother plants in agricultural ecosystems, agroforestry and natural habitats, ...

In September 2013, the European Commission published a proposal for a Regulation on the prevention and management of the introduction and spread of invasive alien species. The proposal aims to address the threat of invasive alien species comprehensively, minimising and mitigating their impacts on...

Chromolaena odorata (L.) King and Robinson (Asteraceae), a shrub native to tropical America, was first introduced into West Africa (Nigeria) in 1937, and later became invasive. The weed has since spread to other countries in the West African subregion, threatening agriculture, biodiversity and...
