Resumen:
The dispersal–body mass association has been highlighted as a main determi-
nant of biodiversity patterns in metacommunities. However, less attention has
been devoted to other well-recognized determinants of metacommunity
diversity: the scaling in density and regional richness with body size.
Among active dispersers, the increase in movement with body size may
enhance local richness and decrease β-diversity. Nevertheless, the reduction
of population size and regional richness with body mass may determine a
negative diversity–body size association. Consequently, metacommunity
assembly probably emerges from a balance between the effect of these scal-
ings. We formalize this hypothesis by relating the exponents of size-scaling
rules with simulated trends in α-, β- and γ-diversity with body size. Our
results highlight that the diversity–body size relationship in metacommunities
may be driven by the combined effect of different scaling rules. Given their
ubiquity in most terrestrial and aquatic biotas, these scaling rules may rep-
resent the basic determinants—backbone—of biodiversity, over which other
mechanisms operate determining metacommunity assembly. Further studies
are needed, aimed at explaining biodiversity patterns from functional relation-
ships between biological rates and body size, as well as their association with
environmental conditions and species interactions.
