Optimised ICP-MS quantification method for using animal faeces as a measure of protected area ecosystem health

Autor: Andrea B. Webster, Andre Ganswindt, Charney Small, Riana Rossouw

Publikováno v: MethodsX, Vol 8, Iss , Pp 101441- (2021)

Pollution is a key threat to biodiversity and ecosystem health within protected areas. Using a non-invasive, multi-matrix approach, sediment, vegetation and faecal material from lion (Panthera leo) and giraffe (Giraffa camelopardalis) were collected

The quantification of dissolved metals in seawater requires pre-treatment before the measurement can be done, posing a risk of contamination, and requiring a time-consuming procedure. Despite the development of automated preconcentration units and so

Assessment of trace element concentrations in sediment and vegetation of mesic and arid African savannahs as indicators of ecosystem health

Autor: Andre Ganswindt, Riana Rossouw, Andrea B. Webster, Nigel C. Bennett, F. Javier Callealta

Publikováno v: The Science of the total environment. 760

The savannah biome supports unique biodiversity and provides a multitude of ecosystem services. Defining background concentrations for trace elements in the environment is beneficial for the determination of nutrient deficiencies/hotspots and for the

3230–3200 Ma post-orogenic extension and mid-crustal magmatism along the southeastern margin of the Barberton Greenstone Belt, South Africa

Autor: Riana Rossouw, Willem de Wet, Cristiano Lana, Gary Stevens, Ian S. Buick

Publikováno v: Journal of Structural Geology. 33:844-858

The Barberton Granitoid-Greenstone Terrain (South Africa) preserves a complex and protracted evolution involving several events of magmatism and terrain accretion along convergent tectonic boundaries. Recent studies propose that the main period of te
