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