Can thermoregulation explain differences in habitat selection and distribution range in Calopteryx damselflies?
Body temperature is important for the behavioural and ecological performance of winged insects whose body temperature must exceed ambient temperature to fly. Although thermoregulation may affect geographical distribution and habitat selection of closely related species. The few studies that have been done on this subject have shown mixed results. Our aim was to study whether thermoregulation affects the coexistence of Calopteryx damselflies. We studied the body temperature of C. virgo and C. splendens under both field and laboratory conditions using an insect thermometer. These damselflies are ideal for studying thermoregulation, because they are closely related, but vary in colouration and size – factors that heavily influence insect thermoregulation. Results from our field and laboratory studies were consistent. Individual temperatures followed ambient temperatures linearly on a level ∼3 °C above it. C. virgo could maintain higher body temperatures than C. splendens. Individual body temperature at the activation, or the time before activation was not affected by species, sex or wing size. However, C. virgo warmed up faster than C. splendens in laboratory conditions. Thermoregulation may be a key factor explaining differences in geographical distribution, habitat preferences and behavioral differences between these species. The more melanized species C. virgo has a northern distribution range than less melanized C. splendens. Additionally, C. virgo inhabits shadier brooks and rivers whereas C. splendens prefers open and sunny habitats. C. virgo also wakes up earlier and is a more effective territorial contestant than C. splendens. These differences may partly be explained by their thermoecological differences.
期刊介绍:
The Journal of Thermal Biology publishes articles that advance our knowledge on the ways and mechanisms through which temperature affects man and animals. This includes studies of their responses to these effects and on the ecological consequences. Directly relevant to this theme are:
• The mechanisms of thermal limitation, heat and cold injury, and the resistance of organisms to extremes of temperature
• The mechanisms involved in acclimation, acclimatization and evolutionary adaptation to temperature
• Mechanisms underlying the patterns of hibernation, torpor, dormancy, aestivation and diapause
• Effects of temperature on reproduction and development, growth, ageing and life-span
• Studies on modelling heat transfer between organisms and their environment
• The contributions of temperature to effects of climate change on animal species and man
• Studies of conservation biology and physiology related to temperature
• Behavioural and physiological regulation of body temperature including its pathophysiology and fever
• Medical applications of hypo- and hyperthermia
Article types:
• Original articles
• Review articles
