Overlap between vulnerable top predators and fisheries in the Benguela upwelling system: implications for marine protected areas (2009)
Journal Article
Pichegru, L., Ryan, P., Le Bohec, C., van der Lingen, C., Navarro, R., Petersen, S., Lewis, S., van der Westhuizen, J., & Grémillet, D. (2009). Overlap between vulnerable top predators and fisheries in the Benguela upwelling system: implications for marine protected areas. Marine Ecology Progress Series, 391, 199-208. https://doi.org/10.3354/meps08283

Industrial-scale fisheries are often thought to reduce food availability for top predators. It is essential to estimate the spatial and temporal overlap over a fine scale between fisheries and predators during their breeding season, when their energy...

Underwater wingbeats extend depth and duration of plunge dives in northern gannets Morus bassanus (2009)
Journal Article
Ropert-Coudert, Y., Daunt, F., Kato, A., Ryan, P. G., Lewis, S., Kobayashi, K., Mori, Y., Grémillet, D., & Wanless, S. (2009). Underwater wingbeats extend depth and duration of plunge dives in northern gannets Morus bassanus. Journal of Avian Biology, 40(4), 380-387. https://doi.org/10.1111/j.1600-048x.2008.04592.x

Plunge-diving is a specialised hunting tactic used by some avian predators to overcome the high buoyancy encountered near the water surface and surprise prey. However, plunge-diving is effective only to a certain depth; to access deeper prey, birds n...

Effects of extrinsic and intrinsic factors on breeding success in a long lived seabird (2009)
Journal Article
Lewis, S., Elston, D. A., Daunt, F., Cheney, B., & Thompson, P. M. (2009). Effects of extrinsic and intrinsic factors on breeding success in a long lived seabird. Oikos, 118(4), 521-528. https://doi.org/10.1111/j.1600-0706.2008.17308.x

There is growing concern over the impacts of climate change on animal species. Many studies have demonstrated impacts of climate change at the population level, and density dependent effects of climate are frequently reported. However, there is an in...
