Description
Competing phylogenetic models have been proposed to explain the success of species introduced to other communities. Here, we present a study predicting the establishment success of birds introduced to Florida, Hawaii, and New Zealand using several alternative models, considering species' phylogenetic relatedness to source and recipient range taxa, propagule pressure, and traits. We find consistent support for the predictive ability of source region phylogenetic structure. However, we find that the effects of recipient region phylogenetic structure vary in sign and magnitude depending on inclusion of source region phylogenetic structure, delineation of the recipient species pool, and the use of phylogenetic correction in the models. We argue that tests of alternative phylogenetic hypotheses including the both source and recipient community phylogenetic structure, as well as important covariates such as propagule pressure, are likely to be critical for identifying general phylogenetic patterns in introduction success, predicting future invasions, and for stimulating further exploration of the underlying mechanisms of invasibility.
Notes
Column names:
Columns with the prefix "s_" or "r_" refer to metrics calculated relative to the source or recipient community, respectively. Columns containing "_n_", "_e_", or "_ne_" refer to metrics calculated relative to native species, established species, or both native and established species, respectively. The abbreviations "pd", "nnd", "mpd", "vpd","spd", and "kpd" refer to Faith's Phylogenetic Diversity, Phylogenetic Nearest Neighbor Distance, Mean Phylogenetic Distance, Variance of Phylogenetic Distance, Skewness of Phylogenetic Distance, and Kurtosis of Phylogenetic Distance, respectively.
Transformations:
All continuous variables (phylogenetic metrics, richness metrics, and area metrics) have been scaled and centered.
