Towards a predictive model of species interaction beta diversity

Abstract: Species interactions are fundamental to community dynamics and ecosystem processes. Despite significant progress in describing species interactions, we lack the ability to predict changes in interactions across space and time. We outline a Bayesian approach to separate the probability of species co‐occurrence, interaction and detectability in influencing interaction betadiversity. We use a multi‐year hummingbird–plant time series, divided into training and testing data, to show that including models of detecta… Show more

“…(Our results also hold when A ij,u and A ji,u are correlated, see S1 Text (Appendix F).) For a given species pair, its interactions A ij,u vary somewhat with u; this variability corresponds to small differences in the conditions between the patches [23]. In the simulation examples we set all carrying capacities B i,u = 1; the phenomena described below are also found if B i,u vary between patches in addition to, or instead of the interaction coefficients.…”

“…Interaction -diversity represents differences in the set of observed interactions between sites (Poisot et al 2012, Graham andWeinstein 2018). Whole-network dissimilarity ( ) between two sites can be partitioned into that attributable to species not being present at both sites ( ) and that attributable to interactions only occurring at one site despite both species being present at both ( ).…”

“…they belong to the same trophic level), meaning that A ij,u are sampled independently 2 and identically for different (i, j). For a given species pair, its interactions A ij,u vary somewhat with u; this variability corresponds to small differences in the conditions between the patches [16]. In the simulation examples we set all carrying capacities B i,u = 1; the phenomena described below are also found if B i,u vary between patches in addition to, or instead of the interaction coefficients.…”
