Details

The giant day gecko (Phelsuma madagascariensis grandis) is a tropical reptile naturally occurring in the northern part of Madagascar. Data represent an extensive capture-recapture experiment at the Masoala rainforest exhibit, Zurich Zoo. The researchers used the individual color patterns of this gecko species for photo recognition. Due to the high number of sampling sessions, this study is based on an unusually good dataset. Moreover, it is a captive population and, therefore, we can be sure that the closed population assumption is valid. However, the dataset is comparable to natural conditions because of the dimensions of the Masoala rainforest exhibit; it is currently the second largest tropical exhibit in the world. Additional variation in the dataset results from time-dependent variation in recapture rates (obvious dependence of gecko activity on daily weather) and the photographic capture method (it is harder to spot and photograph juvenile compared to adult geckos).
