Tracking the Pulse of the Dunes: Seasonal Metabolic Responses of Liolaemus arambarensis to Climatic Variability

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT Seasonal environmental fluctuations profoundly influence ectothermic vertebrates, regulating their physiology, metabolism, and life cycles. This study investigated the metabolic and morphometric seasonal dynamics of the subtropical sand lizard Liolaemus arambarensis, an endangered species endemic to the coastal dunes of southern Brazil.
