“…Although the mechanical bases of these trade‐offs are well‐understood at lower levels of organization, evidence of trade‐offs at the organismal level is inconsistent (Wilson & James, ). For example, sprinting and endurance running have incompatible morphological and physiological requirements, namely the short‐term generation of anaerobic power (T. M. Williams et al, ; Williams, Wilson, Rhodes, Andrews, & Payne, ) versus long‐term, efficient oxygen delivery, respectively (Lindstedt et al, ; McKean & Walker, ; Myers & Steudel, ; Steudel, ). Despite this incompatibility, studies have variously found strong (Herrel & Bonneaud, ), mixed (Vanhooydonck et al, ), or no support (de Albuquerque, Bonine, & Garland, ; Huey, Dunham, Overall, & Newman, ; Sorci, Swallow, Garland, & Clobert, ; Wilson, James, & Van Damme, ) for such a trade‐off at both the intra‐ and interspecific levels, and sometimes conflicting results from the same taxa (e.g., lacertid lizards; Vanhooydonck et al, ; Vanhooydonck, Van Damme, & Aerts, ).…”
