Diversity and tree neighborhood effects on the growth dynamics of European beech and the stand seed bank in temperate broad-leaved forests of variable tree diversity
Von denjenigen aktuellen Studien, die sich mit dem Effekt der Artendiversität auf ökosystemare Funktionen beschäftigen, setzen sich nur wenige mit langfristigen Veränderungen auseinander. Vor diesem Hintergrund befasse ich mich in meiner Dissertation mit Analysen der Bodensamenbank sowie …

Molecular screening of potential bat-borne hantavirus and determination of species richness and composition of bats in selected habitats within the woodland and savanna biomes in Namibia
… hantaviruses at selected habitats in the broad-leaved tree and shrub savanna, and the Acacia tree and shrub savanna biomes in Namibia. Live bats were sampled using Dinier mist nets, biometrically processed and the species identifications were morphologically and molecularly determined. …

A vegetation survey of the Cape of Good Hope Nature Reserve
… tested. Subjectively, two formations, Fynbos and Broad-leaved Scrub, were recognized. Fynbos was subdivided into two alliances, Coast and Inland, and ten individually described associations. The association-analysis, based on 100 grid samples each 5 x 10 metres in extent, revealed 23 final groups. …

Long-term vegetation change in the Cape of Good Hope section of Table Mountain National Park, in response to climate, fire and land use
… cover and the cover of major growth forms (broad leaved shrubs, proteoids, ericoids and restioids) within three main vegetation types (Dune Asteraceous Fynbos, Restioid Fynbos and Proteoid Fynbos) were assessed. Transition matrices were used to investigate the extent of vegetation change …
