Partitioning of Time as an Ecological Resource

摘要: ▪ Abstract Animal species have evolved different diel activity rhythms that are of adaptive value. Theory suggests temporal partitioning may facilitate coexistence between competitors and predators prey. However, relatively few studies demonstrate a shift is predation- or competition-induced. Recorded shifts usually within the preferred phase animal (day night), although there some inversions to opposite cycle. Temporal not perceived as common mechanism coexistence. This rarity has been variously ascribed theoretical considerations rigidity time-keeping mechanisms, well other physiological anatomical traits constrain patterns. Our decade-long study spiny mice rocky deserts demonstrates that, while factors select for patterns, endogenous rhythmicity be an evolutionary constraint.
