Patterns of species association: Quantifying and detecting patterns of association in ecological communities Patterns of non-random species association (co-occurrence), which are common, are frequently used as an indicator of the processes responsible for shaping ecological communities. While a great deal of effort has gone into developing and evaluating the statistical methods used to detect non-random patterns of association, and the metrics used to quantify them, questions remain about their performance. I present research investigating the performance of various methods and metrics used to explore species co-occurrence patterns and, ultimately, provide recommendations on what methods work for detecting significant patterns of association within ecological communities.
