Abstract Chrysophyceae are a diverse group of planktonic protists widely distributed in freshwater. They encompass variety orders, whereby heterotrophy has evolved independently several phylogenetic lineages. Therefore, closely related taxa that developed different feeding strategies (photo-, mixo-, heterotrophy). In high-throughput sequencing studies, the were usually addressed as rather than ...

Abstract Protection of Antarctica's biodiversity and ecosystem values is enshrined in the Protocol on Environmental to Antarctic Treaty, which provides for designation Specially Protected Areas (ASPAs) areas with outstanding values. Concern has been raised that existing ASPAs fail prioritize maximize likelihood ensuring long-term conservation ecosystems biodiversity. The absence systematic repr...

Characterizing the specific inherent optical properties (SIOPs) of water constituents is fundamental to remote sensing applications. Therefore, this paper presents the absorption properties of phytoplankton, gelbstoff and tripton for three small, optically-diverse South African inland waters. The three reservoirs, Hartbeespoort, Loskop and Theewaterskloof, are challenging for remote sensing, du...

The long term goal of this research is to significantly advance computational models for multi-scale flow physics in geometrically and/or hydrodynamically complex oceanic and coastal ocean environments, through refinements in the defined physics, domain definition and computational grid resolution. The particular focus is on improved coupling of spectral wave models and circulation models withi...
