The world's beaches are under severe pressure because of anthropogenic modification and climate change. The most common coastal management approaches have focused largely on the protection of infrastructure without considering the function of the bea

The Albany Thicket Biome is highly resistant to a wide variety of disturbances but, once disturbed, lacks the regenerative qualities that allow it to return to its original stable state. This study investigated the degradation status and the remainin

Worldwide, cyanobacterial blooms are becoming more frequent, exacerbated by eutrophication, anthropogenic effects, and global climate change. Environmental factors play a direct role in photosynthesis of cyanobacteria and subsequent cellular changes,

Aim The sub-escarpment coastal plains of South Africa provide remarkable opportunities to study the determinants of biome boundaries as numerous biomes are found closely juxtaposed, including the Nama-Karoo semi-desert shrubland and Albany subtropica

The accumulation of high biomass of diatoms in the surf zone is a characteristic feature of some sandy beaches where the wave energy is sufficiently high. A few species of diatoms, called surf diatoms, thrive in this harsh environment. The main proce

Open-ocean sandy beaches are coastal ecosystems with growing relevance in the face of global change. They provide key ecosystem services, such as storm buffering, nutrient cycling, water purification, nursery habitats for resource species, and feedin

Southern right whales (Eubalaena australis) were absent along the Eastern Cape coast, South Africa, for more than a century after overexploitation by land-based whalers in the early 1800s. Currently, mother-calf pairs in particular are again frequent

The winter-rainfall region of southern Africa, covered largely by the fynbos and succulent karoo biomes, harbours the world’s greatest concentration of geophyte species. Species diversity is greatest in the south-west, where more than 500 species c

The Mngazana estuary supports the third largest area of mangroves, and probably the largest stand of Rhizophora mucronata Lamk., in South Africa. The objective of this study was to determine the extent of harvesting in the Mngazana mangrove forest, u
