Individual variation in reproductive success in the wandering Albatross
To conserve threatened species it is important to protect the productive individuals, and so I aimed to identify factors accounting for individual-level variation in long-term reproductive success. I examined current breeding characteristics that might explain past reproductive performance amongst …

Trajectories of Change in South Africa's Freshwater Fish Fauna
In South Africa, freshwaters are the most threatened ecosystems in the country, facing pressure from water abstraction, land-use change, pollution, invasive species and climate change. These anthropogenic pressures are directly impacting the diversity, abundance, and survival of freshwater fauna …
