The conservation status and population decline of the African penguin deconstructed in space and time
Waller, Lauren J.; Sherley, Richard B.; Crawford, Robert J.M. (Wiley-Blackwell, 2020)Understanding changes in abundance is crucial for conservation, but population growth rates often vary over space and time. We use 40 years of count data (1979–2019) and Bayesian state-space models to assess the African ... -

Nest-type associated microclimatic conditions as potential drivers of ectoparasite infestations in African penguin nests
Waller, Lauren J.; Espinaze, Marcela P.A.; Hui, Cang (Springer Nature, 2020)Nest design and characteristics can influence the microclimatic conditions in the nest. Nest-dwelling ectoparasites are sensitive to temperature and moisture and as such the conditions in the nest can influence parasite ...
