Vitale bodem als basis voor een duurzaam bodembeheer
(AOSIS Publishing, 2006)
In the past decades, soils in South Africa as well as The Netherlands have become increasingly
deteriorated as a result of chemical and physical factors. Soil contamination, acidification, desiccation and
erosion have ...
First finding of the parasitic fungus Hesperomyces virescens (Laboulbeniales) on native and invasive ladybirds (Coleoptera, Coccinellidae) in South Africa
(EDP Sciences, 2016)
Hesperomyces virescens is a fungal ectoparasite (Laboulbeniales) that infects adult ladybirds. Research has recently focused on this parasite due to the discovery of its prevalence on the globally invasive harlequin ladybird ...
A river health assessment of selected Southwestern Cape rivers : riparian vegetation index (RVI) application, evaluation and alternatives
(Stellenbosch : Stellenbosch University, 2003-12)
ENGLISH ABSTRACT: This study focuses on riparian vegetation condition at sites along three nvers within the
southwestern Cape, South Africa namely the Lourens, Hout Bay and Palmiet Rivers. The Riparian
Vegetation Index ...
Lake Tanganyika - a melting pot of ancient and young cichlid lineages (teleostei: cichlidae)?
(Public Library of Science, 2015)
A long history of research focused on the East Africa cichlid radiations (EAR) revealed discrepancies between mtDNA and nuclear phylogenies, suggesting that interspecific hybridisation may have been significant during the ...
Genetic analysis shows low levels of hybridization between African wildcats (Felis silvestris lybica) and domestic cats (F. s. catus) in South Africa
(John Wiley & Sons Ltd., 2015)
Hybridization between domestic and wild animals is a major concern for biodiversity conservation, and as habitats become increasingly fragmented, conserving biodiversity at all levels, including genetic, becomes increasingly ...
Indirect effects of habitat disturbance on invasion : nutritious litter from a grazing resistant plant favors alien over native Collembola
(John Wiley & Sons Ltd., 2015)
Biological invasions are major threats to biodiversity, with impacts that may be compounded by other forms of environmental change. Observations of high density of the invasive springtail (Collembola), Hypogastrura manubrialis ...
Biodegradering van sintetiese gas-tot-vloeistof-diesel, biodiesel en hul mengsels
(AOSIS Publishing, 2015-11-30)
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 ...
’n Vergelykende ondersoek na die akkumulering van metale in die mosselkrewel (Tetraclita serrata) en die swartmossel (Choromytilis meridionalis) in Valsbaai, Suid-Afrika
(AOSIS Publishing, 2014)
Die ontwikkeling van metodes om die Suid-Afrikaanse kuswaters te moniteer, bied geweldige
uitdagings. Kennis en die beskikbaarheid van geskikte spesies wat as biomoniteerders kan
optree, kan nuttig wees om inligting te ...
Kan die gevoeligheid van grondlewende organismes bydra om die volhoubaarheid van landbewerking van olieraffinadery afval te beoordeel?Can the sensitivity of soil-dwelling organisms to landfarmed soils contribute to asess the sustainablity of landfarming of oil refinery waste?
(AOSIS Publishing, 2015)
Voordelige grondlewende organismes lewer ekostelseldienste in gesonde grondtipes.
Olieraffinaderye genereer groot hoeveelhede soliede afval wat verskeie tipes koolwaterstowwe en metale bevat wat in die grond geploeg word ...
Spatial turnover in host-plant availability drives host-associated divergence in a South African leafhopper (Cephalelus uncinatus)
(BioMed Central, 2017)
Background
The evolution of reproductive isolation between herbivorous insect populations is often initiated by shifts to novel host-plants, a process that underlies some of the best examples of ecological speciation. ...
