Publikováno v: Biological Invasions. 23:2729-2747

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 oligoha

Abundance and Diversity of Fish Assemblages Along the River-Estuary Continuum in a Fluvially Dominated Southern African Coastal System

Autor: Nadine A. Strydom, SJ Lamberth, Festus P. Nashima

Publikováno v: Estuaries and Coasts. 44:2291-2306

Estuaries are amongst the most productive ecosystems worldwide and provide nursery habitat for fish species of marine and freshwater origin; however, the distribution and community structure of fishes within freshwater-dominated coastal system is lim

An Estuary Ecosystem Classification that encompasses biogeography and a high diversity of types in support of protection and management

Autor: Alan K. Whitfield, Janine B. Adams, JK Turpie, Nicola C. James, SJ Lamberth, L van Niekerk, Steven P Weerts, CF MacKay, Anusha Rajkaran

Publikováno v: African Journal of Aquatic Science. 45:199-216

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 inc...

Knysna Estuary health: ecological status, threats and options for the future

Autor: Richard Barnes, J. Wasserman, L van Niekerk, L. Claassens, Janine B. Adams, SJ Lamberth, Nelson A. F. Miranda

Publikováno v: African Journal of Aquatic Science. 45:65-82

The Knysna Estuary is South Africa's most important estuary in terms of conservation, containing an estimated 42% of all estuarine biodiversity. Despite formal protection the estuary is open access...

Assessing the Rigidity of the River Continuum Concept to Fish Species in a Fluvially Dominated Southern African Coastal System

Autor: SJ Lamberth, Festus P. Nashima, Nadine A. Strydom

A continuous gradient of physical and biological processes exists within a river system from headwaters to mouth, according to the River Continuum Concept. In this study, the River Continuum Concept was used to compare patterns in fish assemblages an

Phenotypic plasticity in life-history traits in response to heterogeneous environments has been observed in a number of fishes. Conversely, genetic structure has recently been detected in even the most wide ranging pelagic teleost fish and shark spec

High flow variability and storm events shape the ecology of the Mbhashe Estuary, South Africa

Autor: NC James, JB Adams, AD Connell, SJ Lamberth, CF MacKay, GC Snow, L Van Niekerk, AK Whitfield

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 is s

An Estuary Ecosystem Classification encompassing biogeography, size and types of diversity that supports estuarine protection, conservation and management

Autor: L Van Niekerk, JB Adams, NC James, SJ Lamberth, CF MacKay, JK Turpie, A Rajkaran, SP Weerts, AK Whitfield

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 introduces new
