Cross-Taxon Congruence of Taxonomic and Functional Beta-Diversity Facets Across Spatial and Temporal Scales

An intensively debated issue in ecology is whether the variations biodiversity patterns of different biological groups are congruent space and time. In addition, ecologists have recognized necessity accounting for both taxonomic functional facets when analysing spatial temporal congruence patterns. This study aimed to determine how cross-taxon beta diversity varies across time, using data from four floodplains at a continental scale. Our general hypothesis was that between aquatic groups, either or functional, would decrease with “between-group” distance. Also, we examined varied scales by focusing on relationships differ among Brazilian dry/wet periods. comprised information eight largest river-floodplain systems, assessed Procrustes analysis. results show detailed analyses can reveal congruence, partially support strength negatively related between-group
