Sloths are among the most specialized arboreal species and have evolved a suite of
anatomical features that support suspensory behaviors. While sloths generally show a …

Global change imposes multiple challenges on species and, thus, a reliable prediction of
current and future vulnerability of species must consider multiple stressors and intrinsic traits …

Sloths exhibit almost obligatory suspensory locomotion and posture. These behaviors
require both strength and fatigue resistance, although we previously found muscle fiber type …

Sloths exhibit below branch locomotion whereby their limbs are loaded in tension to support
the body weight. Suspensory behaviors require both strength and fatigue resistance from the …

Primates spend on average half as much energy as other placental mammals while
expressing a wide range of lifestyles. However, little is known about how primates adapt …

Abstract Changes in ambient temperature and solar radiation may affect sloths' metabolic
