Overlap between vulnerable top predators and fisheries in the Benguela upwelling system: implications for marine protected areas
The study suggests the potential for intense competi- tion between purse-seine fisheries and decreasing seabird populations in the southern Benguela and suggests the inclusion of a suitable ecological buffer when setting fishery quotas.

Range expansions across ecoregions: interactions of climate change, physiology and genetic diversity.
Empirical evidence is provided that NIS, regardless of their thermal tolerance, range size and genetic variability, are expanding their ranges and increasing in abundance, which suggests that climate change fosters the spread and abundance of NIS across multiple spatial scales.
Food Addition and Twinning Experiments in the Cape Gannet: Effects on Breeding Success and Chick Growth and Behavior
- R. Navarro
The results suggest that chicks regulate their food intake and cannot increase their growth rate in response to the extra food and the hypothesis of Cape Gannet numbers being limited by food during the breeding season (Ashmole's hypothesis), suggesting instead high food availability during the study period.

Opportunistic Subsistence Strategies among Late Holocene Coastal Hunter-Gatherers, Elands Bay, South Africa
ABSTRACT Hunting and gathering was practiced for many hundreds of thousands of years in South Africa's Western Cape region, until ceramics and a stock-keeping economy first appeared c. 2,000 years…

The Riddle of the Sands: Why are Shorebird Densities so High in Southern Estuaries?
It is concluded that wader populations track the carrying capacities of coastal wetlands across a wide latitudinal range, contrary to predictions of some models.
