Zooplankton Species Composition and Diversity in Floodplain Ponds: Effects of Flooding and Local Site Characteristics
… species pool together shape local communities. Physicochemical characteristics and biotic interactions influence local conditions and physical connection through flooding provides dispersal corridors for inundated pond communities. I explored crustacean zooplankton community composition and …

In situ monitoring and biogeochemical cycling of nutrients in estuarine waters
… for monitoring nitrate, phosphate and master variables in the environment. Chapter One presents a general overview of nutrients, how they are essential for aquatic biota, their general characteristics and the importance of their behaviour in estuaries. Commonly used analytical methods for …

Improving microbial fate and transport modeling to support TMDL development in an urban watershed
… correlations with hydrometeorological and physicochemical variables were identified. An intensive six storm intra-sampling campaign quantified and contrasted loading trends of both traditional regulatory FIB and emerging Microbial Source Tracking (MST) markers. Together, these intensive …

The assessment of water supply system efficiency and water quality in Standerton, Lekwa Municipality, Mpumalanga, South Africa
… Escherichia coli and total coliforms, as well as physicochemical variables like pH, turbidity, free chlorine, electrical conductivity (EC), total dissolved solids (TDS), manganese (Mn), and iron (Fe). The results showed that pH, EC, and TDS consistently met the acceptable limits throughout the …

Sediment-effects on seagrass Zostera muelleri in New Zealand
… between receiving irradiance, substrate physicochemical variables and Z. muelleri traits in Pāuatahanui Inlet, were explored using an observational seasonal survey. A series of experiments followed, that used field and mesocosm-based methods that allowed deeper analysis of how sediment …

Cytochrome P450 whole cell biohydroxylation of alkanes
… which alkanes are transferred is determined by variables such as solubility, thermodynamic equilibrium, cell membrane permeability, temperature etc. The kinetics of the biocatalytic reaction are partly dependent on physicochemical variables, but also on biological parameters such as cellular …
