Marine ecosystem classification and conservation targets within the Agulhas ecoregion, South Africa
Deep-sea benthic ecosystems remain poorly studied in South Africa, limiting understanding of community biodiversity patterns and their environmental drivers. This is one of the first studies to (i) visually investigate marine epifaunal community patterns and their environmental drivers along the …

The influence of sampling method on detecting benthic biodiversity patterns at the ecoregion scale on the South African west coast
… Both datasets inform the national marine ecosystem classification, yet the consistency between biodiversity patterns detected by each sampling method has not yet been explored. The aim of this thesis is to determine the influence of sampling method on the detection of benthic biodiversity …

Design of a watershed-based nitrogen trading system or the Big and Little Wood Rivers Watershed
… nitrogen concentration values from EPA Ecosystem classification data, trophic states, and published data. Trading credits would be distributed to point sources in proportion to their current acceptable discharge levels and to non-point sources in proportion to the amount of land used for …

Ecological site quality, site index, and height growth of white spruce stands in the sub-boreal spruce zone of British Columbia
… the principles and methods of biogeoclimatic ecosystem classification, statistical analysis, and growth modelling. Using vegetation classification, the study stands were organized into eight seral plant associations on the basis of differences in the floristic composition of understory …

Laminated root rot: ecology relationship and stand productivity impacts in coastal Douglas-fir ecosystems of British Columbia
… root rot in coastal second growth Douglas-fir ecosystems of southeastern Vancouver Island was investigated in 139 ecosystems centered around 215 growth and yield permanent sample plots (PSP's). The impact of Phellinus root rot on stand productivity was estimated from PSP records and a percent …

Towards informing a data-driven approach to marine bioregionalization in South Africa: a case study using benthic epifaunal datasets from the southern Benguela shelf
Marine bioregional, ecosystem and habitat classifications and maps are important for understanding and managing the marine environment. Benthic epifaunal assemblages often inform marine ecosystem classifications and maps, being recognized as good surrogates for broad benthic biodiversity patterns. …
