...Maiah E. M. Devereaux; Sarah Chiasson; Kate F. Brennan; Matthew E. Pamenter ABSTRACT Damaraland mole-rats ( Fukomys damarensis ) are a hypoxia-tolerant fossorial species that exhibit a robust hypoxic metabolic response (HMR) and blunted hypoxic ventilatory response (HVR). Whereas the HVR of most...

...Maiah E. M. Devereaux; Matthew E. Pamenter ABSTRACT Fossorial Damaraland mole-rats ( Fukomys damarensis ) mount a robust hypoxic metabolic response (HMR) but a blunted hypoxic ventilatory response (HVR) to acute hypoxia. Although these reflex physiological responses have been described previously...

... hypoxic ventilatory response, robust metabolic rate suppression and decreased thermogenesis ( Mortola, 1999 ; Mortola et al., 1989 ). In most adult hypoxia-intolerant mammals, ventilatory and metabolic responses to hypoxia are regulated by excitatory glutamatergic signalling pathways ( Pamenter et al...

... that, like many other semi-aquatic and fossorial small mammals, star-nosed moles would exhibit: (i) a blunted (i.e. delayed or reduced) hypoxic ventilatory response, (ii) a reduced metabolic rate and (iii) a lowered body temperature ( T b ) in hypoxia. We thus non-invasively measured these variables from...

... of either paralog of Hif-1α greatly reduces hypoxia tolerance, indicating the importance of both paralogs to the hypoxic response. Here, with an emphasis on the cardiorespiratory system, we focus on the role of Hif-1α in the hypoxic ventilatory response and the regulation of cardiac function. We explore...

...Milica Mandic; Yihang K. Pan; Kathleen M. Gilmour; Steve F. Perry ABSTRACT Fish increase ventilation during hypoxia, a reflex termed the hypoxic ventilatory response (HVR). The HVR is an effective mechanism to increase O 2 uptake, but at a high metabolic cost. Therefore, when hypoxia becomes severe...

... volumes), for mice that were caught and tested at their native altitudes and those lab-raised in normoxia. Lab-raised progeny of each population were also tested at post-natal day (P)7, 14, 21 and 30. Highlanders developed an enhanced hypoxic ventilatory response by P21, concurrent with the full...

... that independently colonized the high Andes. We compared ducks from high-altitude populations in Peru (Lake Titicaca at ∼3800 m above sea level; Chancay River at ∼3000–4100 m) with closely related populations or species from low altitude. Hypoxic ventilatory responses were measured shortly after capture...
