ABSTRACTAfrican penguins (Spheniscus demersus) are pursuit-diving seabirds endemic to the coast of southern Africa. In this study, we investigate the presence of seashells and anthropogenic debris ...

Optimal foraging theory suggests that the environment (e.g. distribution of resource patches) will shape an individual's decision to exploit the resource available or explore other locations. Together with the environment and the social context, individual characteristics such as personality have been recently discovered to affect behaviour, offering new insights in the field of behavioural ecology. In many species, personality types differ in breeding success, and foraging behaviour could poten...

In 2016, South Africa became the first African country to draft Marine Spatial Planning (MSP) legislation. The underlying legal framework supports the achievement of ecological, social and economic objectives, but a national policy to grow the oceans economy provides a challenge for ecosystem-based approaches to MSP. During the 2018 International Marine Conservation Congress in Borneo, we convened a special session to discuss particular challenges that will likely apply to any developing country...

Global forage-fish landings are increasing, with potentially grave consequences for marine ecosystems. Predators of forage fish may be influenced by this harvest, but the nature of these effects is contentious. Experimental fishery manipulations offer the best solution to quantify population-level impacts, but are rare. We used Bayesian inference to examine changes in chick survival, body condition and population growth rate of endangered African penguins Spheniscus demersus in response to 8 yea...
