In the past few years, African medicinal plants have received considerable attention, and it has been lamented that the documentation of the continent’s species that are used in traditional medicine lags behind China and ...

Biological invasions are widely acknowledged as a major threat to global biodiversity. Species from all major taxonomic groups have become invasive. The range of impacts of invasive taxa and the overall magnitude of the ...

Biological invasions are a growing problem in South Africa. Many alien species have been introduced for various reasons and through multiple pathways over the past few centuries. Invasive alien reptiles and amphibians ...

Invasive alien species (IAS) are one of the major threats to biodiversity in protected areas and pose a significant management challenge (see Allen, Brown & Stohlgren 2009; Pyšek, Jarošík & Kučera 2002). One of the first ...

The diversity of many marine benthic groups is unlike that of most other taxa. Rather than declining from the tropics to the poles, much of the benthos shows high diversity in the Southern Ocean. Moreover, many species are ...

Abstract Background This study evaluated, using in vitro assays, the antibacterial, antioxidant, and tyrosinase-inhibition activities of methanolic extracts from peels of seven ...

Invasive alien species require co-ordinated strategic management if negative impacts are to be effectively avoided. Here we describe a strategy for the management of Parthenium hysterophorus L. (Asteraceae) in South Africa. ...

National alien species databases indicate the state of a country’s biodiversity and provide useful data for research on invasion biology and the management of invasions. In South Africa there are several different published ...

Environmental variability occurring at different timescales can significantly reduce performance, resulting in evolutionary fitness costs. Shifts in thermoregulatory behavior, metabolism, and water loss via phenotypic ...

Background: The Argentine ant, Linepithema humile, is a widespread invasive ant species that has successfully established in nearly all continents across the globe. Argentine ants are characterised by a social structure ...

Volhoubare en hernubare alternatiewe vir petroleumbrandstowwe word ondersoek vanweë die toenemende aanvraag na brandstof in die vervoerbedryf. Sintetiese brandstowwe soos diesel word van natuurlike gas en steenkool ...

Grond is ’n baie heterogene substraat wat ’n omgewingsmatriks daarstel wat in ruimte en oor tyd kan varieer wat betref pH, organiese koolstof, verspreiding van partikelgrootttes en voginoud. Ook chemiese, fi siese en ...

The South African government, as part of its efforts to mitigate the effects of the ongoing energy crisis, has proposed that biofuels should form an important part of the country's energy supply. The contribution of liquid ...

In a recent Discussion Paper, Hoffmann and Courchamp (2016) posed the question: are biological invasions and natural colonisations that different? This apparently simple question resonates at the core of the biological ...

Pathways to scientific teaching is a compilation of previously published, two-paged articles in Frontiers in ecology and the environment, a publication of the Ecological Society of America. In 2004, this publication instituted ...
