| 英文摘要 | Ectotherms are expected to be particularly vulnerable to climate change-driven increases in temperature. Understanding how populations adapt to novel thermal environments will be key for informing mitigation plans. We took advantage of threespine stickleback (Gasterosteus aculeatus) populations inhabiting adjacent geothermal (warm) and ambient (cold) habitats to test for adaptive evolutionary divergence using a field reciprocal transplant experiment. We found evidence for adaptive morphological divergence, as growth (length change) in non-native habitats related to head, posterior and total body shape. Higher growth in fish transplanted to a non-native habitat was associated with morphological shape closer to native fish. The consequences of transplantation were asymmetric with cold sourced fish transplanted to the warm habitat suffering from lower survival rates and greater parasite prevalence than warm sourced fish transplanted to the cold habitat. We also found divergent shape allometries that related to growth. Our findings suggest that wild populations can adapt quickly to thermal conditions, but immediate transitions to warmer conditions may be particularly difficult. Geothermally warmed habitats provide a unique opportunity to test for routes of thermal adaptation in a natural warming experiment. We used a reciprocal transplant experiment to test for fitness consequences of morphological variation found in threespine sticklebacks (Gasterosteus aculeatus) originating from geothermal and cold habitats. We found evidence of unequal fitness consequences and some evidence that body shape and allometry play a role in this study system.image |
