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...

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...

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...

This is the overview of the status of native and protected breeds of animals in the Republic of Croatia, with reference to those contained in the Nature Park Lonjsko Polje (PPLP), to determine the risk level of the total population of native breeds of domestic animals. Traditionally, management of...

Tropical islands are paradises for potential invaders. They offer ideal conditions for pest proliferation: mild climate, numerous host-plants, and few competitors and natural enemies. The invasion of the glassy-winged sharpshooter, Homalodisca vitripennis Germar (=H. coagulata Say) (Hemiptera:...
