An environmental flow determination method for integrating multiple-scale ecohydrological and complex ecosystem processes in estuaries

Author: Van Niekerk, Lara ; Taljaard, Susan ; Adams, JB ; Lamberth, SJ ; Huizinga, P ; Turpie, JK ; Wooldridge, TH Date: Mar 2019 This paper presents an environmental flow methodology that was developed to accommodate shallow, highly dynamic micro-tidal estuaries found along the wave-dominated coast of South Arica. This method differs to most other approaches that ... Read more
An Estuary Ecosystem Classification that encompasses biogeography and a high diversity of types in support of protection and management

Author: Van Niekerk, Lara ; Adams, JB ; James, NC ; Lamberth, SJ ; MacKay, CF ; Turpie, JK ; Rajkaran, A ; Weerts, Steven P ; Whitfield, AK Date: Mar 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 zonation and ... Read more
High flow variability and storm events shape the ecology of the Mbhashe Estuary, South Africa

Author: James, NC ; Adams, JB ; Connell, AD ; Lamberth, SJ ; MacKay, CF ; Snow, GC ; Van Niekerk, Lara ; Whitfield, AK Date: Mar 2020 The possible impacts of extreme events on the ecology of selected aquatic biota within the Mbhashe Estuary were investigated during a four year (2010–2013) spring sampling programme. During periods of low to average flow conditions the estuary ... Read more

Possible impacts of non-native plant, pathogen, invertebrate and fish taxa on the indigenous ichthyofauna in South African estuaries: A preliminary review

Author: Whitfield, AK ; Adams, JB ; Harrison, TD ; Lamberth, SJ ; Lemley, DA ; Mackay, F ; Van Niekerk, Lara ; Weyl, Olf Date: Apr 2021 We review the possible impacts of non-native biota on the indigenous fishes of South African estuaries, including macrophytes, algae, pathogens, invertebrates, and fishes. Freshwater macrophytes are one of the primary non-native groups in the ... Read more
