Bioregions and future state visioning: a visually integrative approach to the presentation of information for environmental policy and management.
… the most important part of bioregionalism is the bioregions construct. Whatever the philosophical inclinations of bioregionalist authors, the bioregion is presented as an identifiable entity, which is suited to be the basis for the formulation of strategy and planning and it is this that is of …

Bioregional planning in southeastern Tanzania : the Selous-Niassa corridor as a prism for transfrontier conservation areas
… a lens through which the process of constructing bioregions can be understood and the effects of that process on society properly evaluated. It specifically investigates the corridor as a cog in the creation of a bioregion in southeastern Tanzania, namely, the Selous-Niassa transfrontier …

Towards informing a data-driven approach to marine bioregionalization in South Africa: a case study using benthic epifaunal datasets from the southern Benguela shelf
… environmental datasets can sufficiently define bioregions using existing datadriven approaches. As a case study, this research focuses on the southern Benguela shelf, located on the western margin of South Africa, where research trawl and towed camera sampling methods regularly collect …

Land use change and bordering in the Greater Mapungubwe transfrontier conservation area
… are advanced in support of the establishment of bioregions across international borders, namely, that transfrontier conservation areas enhance biodiversity, promote economic development and improve the livelihoods of local communities. Whereas research by ecologists and conservation biologists …

Biogeography and potential factors regulating shallow subtidal reef communities in the western Indian Ocean
… location to the Delagoa Bioregion, one of three bioregions also revealed by post-hoc analyses. Significant differences in total average biomass and trophic structure were evident among bioregions, with a number of inter-bioregional trends in trophic groups being apparent. In total, 12 reef …

Reef Carbonate Budgets & Symbiodiniaceae Diversity in the Arabian Gulf, Western Indian Ocean & Central Indo-Pacific
… to determine reef accretional health in three bioregions: Bahrain (located in the hottest sea on the planet – the Arabian Gulf), the Seychelles (with an environment susceptible to regular El Nino disturbances - Western Indian Ocean) and Indonesia (located within the epicenter of marine …

Spatial variation in small mammal communities across the Karoo Shale Gas Development Area of South Africa
… dominant at most sites, and within most biomes/bioregions; while five rare species were only ever recorded once. Mean α diversity (observed species richness Sobs) per site (2.88 ±1.99) and Shannon-Wiener diversity (1.70 overall, 1.04 ±0.33 per site) were low, with only 5.47 effective species …

Studies of Benthic Macroinvertebrates in Western Virginia Streams as Related to the Implementation of Rapid Bioassessment Techniques
… the subregions into three larger regions called bioregions: the forested hills and mountains (subregion 69a), valleys and plateaus (subregions 66c, 67a, and 67b), and the mountains (subregions 66a, 66b, 67c, and 67d). As an alternative to the ecoregion classification scheme, I classified my …

Developing a classification system for Western Cape wetlands
… the Western Cape were selected from different bioregions and wetland regions. In this project geomorphological characteristics (drainage patterns, landform), hydrological pattern and timing of water availability, were recorded during winter and summer for each studied wetland. Water samples …

Unraveling the mystery of leaf reddening in seagrasses
… were conducted in the world's six seagrass bioregions and a series of experiments were performed with green- and red-leafed Thalassia testudinum shoots in the lower Florida Keys. Results show that leaf reddening is prevalent in seagrasses, occurring in numerous species growing in shallow …

Marine algal virus communities along Southern African coasts
… algal blooms that occurred in 2013 in different bioregions namely Elands Bay (west coast) and Algoa Bay (east coast). Additionally the Cerebos solar salt pans located along the west coast were selected as sample sites to investigate viral composition. DNA polymerase (pol) gene fragments were …

Baited remote underwater video survey of macro-invertebrate distribution and abundance across False Bay, South Africa
… high species richness due to the overlap of two bioregions. This project reports on the first comprehensive camera survey of False Bay’s invertebrate population and assesses diversity across more habitat types and a greater depth range than previous dredge studies. 154 sites were sampled across …

Community composition, migration and trophic positions of micronekton in two biogeochemical provinces of the South West Indian Ocean
… research project carried out in two different bioregions of the South West Indian Ocean: the East African Coastal Province (EAFR) and the Indian South Subtropical Gyre (ISSG). Food web structure was addressed using stable isotopes. Since particulate organic matter had high δ 15 N values in the …

Patterns and processes underlying genetic diversity in the Namaqua rock mouse Micaelamys namaquensis Smith, 1834 (Rodentia : Muridae) from southern Africa
… association with particular vegetation biomes or bioregions. The distributional ranges of eight of these lineages showed some correspondence with the type localities of previously described subspecies of M. namaquensis. Some clades displayed considerable within-lineage variation indicating …

Phylogenetics and biogeography of Australian subterranean Parabathynellidae.
… of extant parabathynellids between subterranean bioregions in Australia. This study found evidence for significant regional biogeographic structuring of parabathynellids at the genus and species levels, indicating a long and complex evolutionary history for these animals in Australia, likely …

Patterns of distribution, abundance and community composition of rock pool fishes in Goukamma Nature Reserve, South Africa
… patterns. These patterns show five distinct bioregions along the South African coastline in that familial distributions tend to be broken by the same oceanographic barriers seen in the distributions of many other marine taxa. The results suggest that rock pool fishes tend to exhibit distinct …
