Studies of the relationship between body mass and population abundance for terrestrial and aquatic animal species based on pooling data from many taxa and assemblages suggest that abundance scales with mass to the -0.75 power. Because metabolic rate scales with mass as (plus) 0.75, this result has been taken as evidence that all species in assembla...

... Body size is often considered a primary axis of a species' ndimensional niche, and this could be reflected in its influence on local patterns of abundance since large-bodied species need more energy than small-bodied species to fuel their metabolisms, and resources in natural ecosystems are finite (Damuth, 1981). The abundance-body size relationship reflects the trade-off between individual-level traits and population-level dynamics of a species (Blackburn & Lawton, 1994;Pedersen et al., 2017 are sampled to give abundance estimates for all the species in a given taxon (Gaston & Blackburn, 2008;Silva & Downing, 1995;White et al., 2007). However, studying the abundance-body size relationship across regions and taxa can help deepen our understanding of how assemblages are structured. ...
