Activity alters how temperature influences intraspecific metabolic scaling: testing the metabolic-level boundaries hypothesis

DS Glazier - Journal of Comparative Physiology B, 2020 - Springer
A common belief is that the body-mass scaling of metabolic rate is the result of intrinsic
(physical) constraints related to body design. However, many recent studies have shown …

Size matters: plasticity in metabolic scaling shows body-size may modulate responses to climate change

N Carey, JD Sigwart - Biology letters, 2014 - royalsocietypublishing.org
