Temperature impacts all behavioral interactions during insect and arachnid reproduction

Area of Science:

• Zoology
• Ecology
• Behavioral Ecology

Background:

• Temperature is a critical environmental factor influencing insect and arachnid reproductive behaviors.
• Existing research often overlooks the nuanced effects of temperature on mating dynamics.

Purpose of the Study:

• To review and synthesize the impacts of temperature on insect and arachnid mating behaviors.
• To highlight the importance of thermal sensitivity in understanding reproductive outcomes.
• To propose a function-valued approach for predicting climate change effects on mating.

Main Methods:

• Literature review synthesizing existing studies on temperature and mating behavior in insects and arachnids.
• Analysis of how prevailing and early-life temperatures affect precopulatory activities, competition, and mate choice.
• Discussion of the utility of function-valued thermal sensitivity measurements.

Main Results:

• Temperature influences precopulatory activity, rival competition, mate communication, and the costs/benefits of mating.
• Both current and early-life thermal conditions shape mating-related behaviors.
• A function-valued approach offers a more precise method for assessing thermal sensitivity.

Conclusions:

• Temperature is a key determinant of insect and arachnid mating success and reproductive strategies.
• Predicting the impact of global warming on these species requires a detailed understanding of thermal sensitivity.
• Integrating function-valued approaches will enhance our ability to forecast future selection pressures on mating interactions.
