Biomass partitioning in an endemic southern African salt marsh species Salicornia tegetaria (Chenopodiaceae)
Brown, Catherine; Rajkaran, Anusha (Taylor and Francis Group, 2020)The below ground biomass of salt marsh species accounts for more than half of the total plant biomass in salt marsh systems, yet no biomass data exist for salt marsh species in South Africa. ... -
Changes in mangroves at their southernmost African distribution limit
Rajkaran, Anusha; Adams, Janine B. (Elsevier, 2020)Mangroves in South Africa occur at one of the most southerly locations in the world, which provides a unique opportunity to study their dynamic responses to anthropogenic and natural perturbations. The exposed high-energy ... -
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
Raw, Jacqueline L.; Van der Stocken, Tom; Rajkaran, Anusha (Wiley, 2022)Latitudinal range limits for mangroves on high-energy, wave-dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global range limit along the South African ... -
Dispersal and coastal geomorphology limit potential for mangrove range expansion under climate change
Rajkaran, Anusha; Raw, Jacqueline L; Van der Stocken, Tom (John Wiley and Sons Inc, 2022)Latitudinal range limits for mangroves on high-energy, wave-dominated coasts are controlled by geomorphological features and estuarine dynamics. Mangroves reach a southern global range limit along the South African coastline, ... -
An estuary ecosystem classification that encompasses biogeography and a high diversity of types in support of protection and management
Rajkaran, Anusha; van Niekerk, Lara; Adams, Janine B. (Taylor & Francis, 2020)For nearly three decades, the Whitfield (1992) characterisation scheme served as a reference framework to type South African estuaries. We outline a revised ecosystem classification scheme that incorporates biogeographical ... -
Opportunities for improving recognition of coastal wetlands in global ecosystem assessment frameworks
Brown, Christopher J.; Adame, Maria F.; Rajkaran, Anusha (Elsevier, 2021)Vegetated coastal wetlands, including seagrass, saltmarsh and mangroves, are threatened globally, yet the need to avert these losses is poorly recognized in international policy, such as in the Convention on Biological ... -
Predicting Shifts in the geographical distribution of two estuarine plant species from the subtropical and temperate regions of South Africa
Veldkornet, Dimitri Allastair; Rajkaran, Anusha (Springer, 2019-11-21)Climate suitability maps are useful to determine changes in the distribution of species. The aim of this study was to predict the future distribution of two estuarine species (Bassia diffusa and Hibiscus tiliaceus) from ... -
A tale of two habitats: preliminary comparison of fish abundance and diversity between saltmarsh- and mangrove-dominated creeks in the Nahoon Estuary, South Africa
Rajkaran, Anusha; Keur, R (University of the Western Cape, 2019)A preliminary assessment of abundance and richness of fishes utilising saltmarsh and mangrove habitats in the Nahoon Estuary, situated on the eastern coast of South Africa, was undertaken during July 2017. The structural ... -
Towards characterising microplastic abundance, typology and retention in mangrove-dominated estuaries
Naidoo, Trishan; Rajkaran, Anusha; Govender, Joelene (MPDI, 2020)Plastic and, particularly, microplastic (MP) pollution is a growing research theme, dedicated largely to marine systems. Occurring at the land–sea interface, estuarine habitats such as mangroves are at risk of plastic ... -
Understanding the creek dynamics and environmental characteristics that determine the distribution of mangrove and salt marsh communities at Nahoon Estuary
Geldenhuys, Chanel; Cotiyane, Phumlile; Rajkaran, Anusha (Elsevier, 2016)The southern distributional limit for mangroves on the east coast of Africa is thought to be at the planted mangrove forest at Nahoon Estuary (33° S) in the Eastern Cape, South Africa. This study investigated the influence of ...
