The role of local-scale processes on terrestrial and deep-sea gastropod body size distributions across multiple scales

Question: Does resource partitioning among body sizes at local spatial scales account for the distribution of body sizes at all spatial scales? Hypothesis: Processes controlling regional or global patterns of species richness within size classes are scale-dependent, with regional or global patterns being influenced by macroevolutionary processes such as size-biased extinction/speciation and constraints on maximum/ minimum size as opposed to...
