Abstract

Desert ants are among the most thermotolerant insects on Earth, thriving in some of the harshest environments where surface temperatures can exceed 60°C. Their remarkable survival is the result of a suite of physiological, molecular, and behavioral adaptations. This research paper explores the mechanisms underlying thermal tolerance in desert ants, with a focus on molecular responses such as heat shock protein expression, physiological traits like water management and cuticular adaptations, and a diverse array of behavioral strategies including time-optimized foraging, navigation, and microhabitat selection. By synthesizing findings from recent studies, this paper demonstrates how desert ants serve as models for understanding adaptation to extreme environments, the limits of ectotherm resilience, and the potential impacts of climate change on thermophilic species.
