Phenotypic Plasticity and Genetic Adaptation to High-Altitude Hypoxia in Vertebrates
On the cover: An American pipit (Anthus rubescens) silhouetted against the Beartooth Mountains of Montana, USA. On page 4125-4136 of this issue, J. F. Storz, G. R. Scott and Z. A. Cheviron review mechanisms of adaptation and acclimatization to high-altitude hypoxia in vertebrates. They conclude that, in birds and mammals, the acclimatization response to environmental hypoxia sometimes represents a form of maladaptive phenotypic plasticity. Thus, blunted erythropoietic and pulmonary vasoconstriction responses to hypoxia may often represent genetically based adaptations that counteract the plastic response.
