De manera tradicional para su estudio, el reparto de recursos, se divide en tres categorias dimensionales, el habitat, el alimento y el tiempo (Schoener 1968; Pianka 1969, 1973, 1975), mismas que pueden subdividirse en macrohabitat
, microhabitat, tipo y tamano de alimento y tiempo de actividad estacional y diaria (Schoener 1974).

Benthic macroinvertebrate assemblages and macrohabitat
connectivity in Mediterranean-climate steams of northern California.
Two null hypotheses were tested and rejected: i) that fishes are randomly distributed with respect to subregion, and ii) that fishes are randomly distributed with respect to macrohabitat
Effects of macrohabitat
and microhabitat on nest-box use and nesting success of American kestrels.
The hypothesis of this study is that correlations exist between nest-sites (nest trees in which primary, cavity-nesters (PCNs) excavate their nest cavities) and macrohabitat
characteristics, such as amount of and distance to edge, openings, trails, and roads.
Traditionally, habitat selection studies have been undertaken from a macrohabitat
