Abstract

Grouping sites on the basis of their biological information is a common goal in ecologythat has scientific and management applications.Two applications are studied in this work:classifying vegetation types for management units and predicting these units into unsampledspace, and finding assemblages of fish and investigating how the presence of these assemblagesvaries with covariates. Data that are used to find the groupings often have extraneoussources of variation, such as those related to sampling, which are often ignored but should beaccounted for when finding the groupings. In ecological studies, this is increasingly commonas data sets are now being combined from many smaller survey efforts. We show, througha model-based clustering method, how the groupings can be obtained, while accounting forsampling artefacts.
