Satellite change detection in the albany thicket biome
The Albany Thicket Biome has been subject to widespread transformation, with as much as 63% of the biome being severely degraded. The primary land use activity responsible for much of the transformation of the biome has been pastoralism and commercial agriculture land expansion (Mills et al., 2005; …

Fire Type Classification in the Brazilian Tropical Moist Forest Biome
<p>The Brazilian Tropical Moist Forest Biome (BTMFB) is “<em>Earth’s greatest biological treasure and a major component of the earth system</em>” and forest degradation and deforestation by fire is a serious issue in this region. Fires in the BTMFB can be broadly classified as maintenance, …

Vegetation studies in the Humansdorp region of the Fynbos Biome
… forest) in the Humansdorp region of the Fynbos Biome. The first paper is a re-evaluation of vegetation concepts in the study area and, more generally, in the Fynbos Biome and adjacent biomes. Syntaxa are characterized in terms of floristics (including biogeographical affinities and patterns of …

ECOLOGICAL AND EVOLUTIONARY DRIVERS OF SPECIES DISTRIBUTIONS IN THE GRASSY BIOME
Research Problem: A biome is a functionally distinct collection of vegetation that occurs according to climatic and soil conditions. For example, rainforests and tropical grasslands should occur in different climates and are expected to differ drastically in their biogeochemical rates, owing to …

Bats and the city : urban bat biodiversity in a tropical biome transition zone
Urbanisation is an important factor in global land-use change which dramatically alters habitats at great detriment to wildlife. Our understanding of urban biodiversity patterns and their driving factors in tropical cities which interact with high levels of biodiversity is limited, yet it is …

ASSESSMENT AND POTENTIAL ADJUSTMENTS TO THE SNOW-RELATED ALGORITHMS IN BIOME-BGC, v4.2
… the effects of climate change on snowpack. BIOME-BGC, a well established eco-system process model, contains a simple snow melt model for predicting daily snow water equivalent (SWE). The model requires standard daily meteorological data and can, therefore, be extrapolated over long periods …

Dietary shifts in pollen-feeding lacewings (Nemopteridae) in relation to vegetation, biome and phylogeny
… the gut contents of nemopterids from different biomes, vegetation and localities. It was hypothesised that diet would be phylogenetically constrained and dietary grouping would reflect phylogeny. In addition, the derived nemopterid lineage thought to have co-evolved with Aizoaceae, (Palmipenna, …

The application of systematic conservation planning in the succulent Karoo biome of South Africa
Systematic conservation planning is about making spatially explicit decisions regarding the use of land, based on the observed or expected biodiversity present at a site and the potential for that same site to support alternative /and-uses that are not compatible with the persistence of …

Commercial wildflower production in the fynbos biome and its role in the management of land-use
… utilizes ecosystems and vegetation of the Fynbos Biome either directly by harvesting of natural plant populations, or indirectly by land transformation for agro-horticultural production. This thesis reports on a study of conservation and management issues arising from: (a) direct veld-harvesting; …

Leaf nutrient draw back as a strategy for tree grass co-existence in the savanna biome
… and grasses manage to coexist in the savanna biome, the niche separation by phenology hypothesis (Scholes and Archer 1997) was tested by observing the seasonal variation in carbon and nitrogen concentrations in leaves and young twigs of two deciduous species, Combretum apiculatum and …
