Digest: temperature variation effects on wolf spider (Schizocosa floridana) courtship behaviors.

How does temperature variation affect signaling and mating behavior in wolf spiders? Rosenthal and Elias (2025. The influence of temperature on courtship and mate choice in a wolf spider: implications for mating success in variable environments. Evolution, 79(4), 641-649. doi:10.1093/evolut/qpaf015) find that temperature affects courtship signal form in wolf spiders, with higher temperatures increasing courtship rates. Additionally, female preferences for courtship traits, such as "chirp" duration, only appear at higher temperatures. These results highlight the importance of understanding how temperature influences signal evolution and function.
