Nutrient pollution in South African estuaries is described using a Driver-Pressure-State-
Impact-Response framework. The root cause ('driver') of deteriorating water quality is rapid …

Microalgae are one of the most important components of estuarine ecosystems, providing
the fuel required to sustain higher trophic levels. Being at the base of aquatic food webs …

Mangroves are one of the most important but threatened blue carbon ecosystems globally.
Rapid urban growth has resulted in nutrient inputs and subsequent coastal eutrophication …

In tropical estuaries, fish diversity varies spatially and temporally due to behavioral
processes such as reproductive migrations, predator avoidance, and foraging, which are …

Water quality characteristics of the heavily urbanised and industrialised Swartkops River
and Estuary in the Eastern Cape have been the focus of several studies since the 1970s …

This study developed a conceptual understanding of climate change responses of salt
marsh in open and closed estuaries and outlined changes in terms of implications for …

Phosphorus (P), a significant biogenic element, plays a key role in the primary productivity of
estuarine and coastal ecosystems. The study determined that the seasonal dynamics of total …

Three surveys were carried out to study the phytoplankton role in influencing the Hg
distribution in a poorly eutrophic estuary by measuring the total Hg (THg) and methylHg …

Modeling approaches are useful tools for assessing the general state of eutrophication and
understanding the effects of multiple stressors on coastal ecosystems. Thus, we …

A survey of the quality of water flowing from micro-system types to the ocean, along the
subtropical east coast of South Africa, showed a wide variation in the concentrations of total …
