Failure to meet the exchangeability assumption in Bayesian multispecies occupancy models: Implications for study design
Gavin G. Cotterill, Douglas A. Keinath, Tabitha A. Graves
2025, Preprint
Bayesian hierarchical models are ubiquitous in ecology. Random effect model structures are often employed that treat individual effects as deviations from larger population-level effects. In this way individuals are assumed to be "exchangeable" samples. Ecologists may address this exchangeability assumption intuitively, but might in certain modeling contexts ignore it altogether,...

Idiosyncratic spatial scaling of biodiversity–disease relationships
Neil A. Gilbert, Graziella Vittoria DiRenzo, Elise Zipkin
2025, Ecography (2025)
High host biodiversity is hypothesized to dilute the risk of vector-borne diseases if many host species are ‘dead ends' that cannot effectively transmit the disease and low-diversity areas tend to be dominated by competent host species. However, many studies on biodiversity–disease relationships characterize host biodiversity at single, local spatial scales,...
