Assessing the adequacy of current fisheries management under changing climate: a southern synopsis

Author: Plagányi, Éva E ; Weeks, Scala J ; Skewes, Tim D ; Gibbs, Mark T ; Blamey, Laura K ; Soares, Muri ; Robinson, William M L ; Poloczanska, Elvira S ; Norman-Lopez, Anna Date: 2011 Climate change is likely to have a significant impact on both target and non-target marine stocks worldwide, with the concomitant need for management strategies capable of sustaining fishing in future. We use several southern hemisphere ... Read more

Diet of the Tristan rock lobster Jasus tristani following the 2011 soya spill at Nightingale Island

Author: Jones, Luke Date: 2017 The spiny lobster Jasus tristani inhabits the Tristan da Cunha Island archipelago in the South Atlantic Ocean 2,400km from the West coast of South Africa. It is commercially exploited across the archipelago and is the main economic source of ... Read more
Ecosystem modelling provides clues to understanding ecological tipping points

Author: Plagányi, Éva E ; Ellis, Nick ; Blamey, Laura K ; Morello, Elisabetta B ; Norman-Lopez, Anna ; Robinson, William M L ; Sporic, Miriana ; Sweatman, Hugh Date: 2014 Ecological thresholds, associated with abrupt changes in the state and organisation of ecosystems, challenge both scientists and managers. Adaptive response to such changes, and planning for their occurrence, requires an understanding of the ... Read more
The environmental factors determining temporal distributions of cetaceans in Mossel Bay, South Africa

Author: Levy, David Date: 2017 A variety of cetacean species make use of the bays along the South African coast for different purposes, including feeding, mating and calving. Sightings of five species of cetaceans were recorded from shore based locations between February ... Read more
Kelp forests in False Bay: urchins vs. macroalgae in South Africa's south-west coast biogeographical transition zone

Author: Morris, Kathryn Date: 2017 There is ongoing global concern over unwanted regime shifts in marine systems. Shifts from diverse and productive algal-dominated ecosystems to less productive urchin and coralline-dominated temperate reefs are becoming increasingly common. ... Read more
Modeling a regime shift in a kelp-forest ecosystem caused by a lobster range expansion

Author: Blamey, Laura K ; Plagányi, Éva E ; Branch, George M Date: 2013 The South African West Coast rock lobster, Jasus lalandii (H. Milne-Edwards, 1837), has expanded its range to the southeast, where its abundance has increased radically. The ecological consequences of this “invasion” are likely to be considerable. ... Read more
Was overfishing of predatory fish responsible for a lobster-induced regime shift in the Benguela?

Author: Blamey, Laura K ; Plagányi, Éva E ; Branch, George M Date: 2014 The top-down effects of predators have been demonstrated for terrestrial, freshwater and marine systems and their removal can cause a shift in ecosystem state. In many cases, the depletion of top-predators occurred long before humans began ... Read more
