| Abstract: | While considerable evidence exists of biogeographic patterns in the
intensity of species interactions, the influence of these patterns on
variation in community structure is less clear. Studying how the
distributions of traits in communities vary along global gradients can
inform how variation in interactions and other factors contribute to the
process of community assembly. Using a model selection approach on
measures of trait dispersion in crustaceans associated with eelgrass (Zostera marina)
spanning 30° of latitude in two oceans, we found that dispersion
strongly increased with increasing predation and decreasing latitude.
Ocean and epiphyte load appeared as secondary predictors; Pacific
communities were more overdispersed while Atlantic communities were more
clustered, and increasing epiphytes were associated with increased
clustering. By examining how species interactions and environmental
filters influence community structure across biogeographic regions, we
demonstrate how both latitudinal variation in species interactions and
historical contingency shape these responses. Community trait
distributions have implications for ecosystem stability and functioning,
and integrating large-scale observations of environmental filters,
species interactions and traits can help us predict how communities may
respond to environmental change |
