The scaling of diving time budgets: insights from an optimality approach.

摘要: Abstract: Simple scaling arguments suggest that, among air‐breathing divers, dive duration should scale approximately with mass to the one‐third power. Recent phylogenetic analyses appear confirm this. The same showed that of time spent at surface between dives has very similar duration, result ratio pause is invariant. This finding runs counter other found in diving literature more positively mass, leading a negative dive‐pause ratio. We use published model optimal allocation cycle show decisions can predict approximate invariance ratio, especially if metabolism scales two‐thirds power (as indicated by some recent analyses) and oxygen uptake assumed have evolved supply body tissues the...
