I will survive! The effects of different predators on survival of early stages of African clawed frog
My study looks at the effects of different predators on three early life stages of Xenopus laevis. The three predators used are adult X. laevis, freshwater crabs and odonate larvae. These are all found in the same environment as the frogs, but have different expected effects on the survival rates of the life-history stages. The stages used are eggs, newly hatched larvae and tadpoles. X. laevis is an important invasive species, thus understanding its predator-prey relationships is important.

Should I stay or should I go? Personality syndromes of migrating African clawed frogs.
I received my science degree in Biodiversity and Ecology last year from the University of Stellenbosch. During my final year of Undergraduate study I assisted John in his lab. I then decided to do my Honours this year with him where I am investigating behavioural syndromes or “personalities” of the African clawed frog Xenopus laevis; differentiating them into groups based on movement and exploration of a novel environment. I then plan on looking for correlations between what I find in the lab and movement data we have from these frogs from an on-going capture-mark-recapture project to untangle the ecological implications such personality variation might have.
