Two subspecies of Chrysanthemoides monilifera, namely subsp. rotundata (DC.) T.Norl. (bitou bush) and subsp. monilifera (L.) T.Norl. (boneseed), have been introduced to Australia from South Africa and are now among our worst environmentalweeds. A biological control program was established in 1987 to combatthese two invaders. To date, six speciesof insects have been released on bitou bush, four ...

Data on the status of caribou {Rangifer tarandus) herds throughout the circumpolar region during the last 20 years were obtained from the literature and personal communication with researchers. Information was analysed in relation to ecotype (insular, montane, barren-ground, and woodland/forest), population status (increasing, stable, decreasing), herd size, human impact, and temporal change i ...

The aim of this study was to investigate inter-specific variation in drought tolerance and survival among three provenances of Acacia tortilis subspecies Raddiana and subspecies Spirocarpa under water stress. The seeds were collected from White Nile (Elgetiana), Kassala (Halfa Elgadida) and River Nile (Shandi) states, where the association of the two subspecies occurs in their natural habitats ...
