Data from: Predicting community structure in snakes on Eastern Nearctic islands using ecological neutral theory and phylogenetic methods

Frank T. Burbrink, Alexander D. McKelvy, R. Alexander Pyron & Edward A. Myers
Predicting species presence and richness on islands is important for understanding the origins of communities and how likely it is that species will disperse and resist extinction. The equilibrium theory of island biogeography (ETIB) and, as a simple model of sampling abundances, the unified neutral theory of biodiversity (UNTB), predict that in situations where mainland to island migration is high, species-abundance relationships explain the presence of taxa on islands. Thus, more abundant mainland species should...

Data from: A hierarchical distance sampling model to estimate abundance and covariate associations of species and communities

Rahel Sollmann, Beth Gardner, Kathryn A. Williams, Andrew T. Gilbert & Richard R. Veit
Distance sampling is a common survey method in wildlife studies, because it allows accounting for imperfect detection. The framework has been extended to hierarchical distance sampling (HDS), which accommodates the modelling of abundance as a function of covariates, but rare and elusive species may not yield enough observations to fit such a model. We integrate HDS into a community modelling framework that accommodates multi-species spatially replicated distance sampling data. The model allows species-specific parameters, but...
