摘要: Animals can profit from increasing temperatures by prolonged breeding seasons and faster growth rates. However, these fitness benefits are traded off against higher parasite load increased virulence of temperature-sensitive pathogens. In thermally stratified habitats, behavioral plasticity allow hosts to choose the optimal temperature enhance individual escape pressure. To test this idea, we performed a choice experiment with host-parasite system sex-role reversed broad-nosed pipefish (Syngnathus typhle) its bacterial pathogen Vibrio spp. species, pregnant males expected face trade-off between shortening their brooding period in warm water decreasing effect infection cold water. We found that exposure changed preference for both nonpregnant males, as well females compared nonchallenged fish tended prefer This study shows is one option avoidance prevalence, due rising ocean temperatures.
