WebEvaporative cooling represents a significant avenue of heat loss for animals. The problem with using evaporative cooling is that there must be a water source for the animal to evaporate. The small size of insects means they have a relatively small water reservoir in their bodies but several evaporative cooling mechanisms have evolved in insects. WebAlthough animals can adapt to climatic stressors, the response mechanisms that ensure survival are also detrimental to performance (Pragna et al., 2024 ). The vulnerability of livestock to heat stress varies according to species, genetic potential, life stage, management or production system and nutritional status (Das et al ., 2016 ).
