Extinction Risk in Novel Communities
John Pandolfi, University of Queensland
Local and global changes cause many ecosystems to be transformed into new configurations through taxonomic turnover and species-abundance changes. This transformation is resulting in what many refer to as ‘novel communities’ - communities with no historical precedence in the ecosystem. But a fundamental gap exists in the comparative analysis of ecosystems as community novelty remains an ill-defined, ill-quantified concept, often lacking a pre-historical context. Here, we develop a robust methodology for the identification of novel communities that allows for investigation of their frequency, causes, and consequences over long temporal scales. We distinguish between instantaneous novelty, in which a community is significantly different from its previous state, and cumulative novelty, in which a community is significantly unprecedented in all previous times. We identify novel communities only when instantaneous and cumulative novelty converge.
