| 요약 | Earth's atmosphere has warmed by approximately 1째C over the past century and continues to warm at an increasing rate. The effects of atmospheric warming are already visible in most major ecosystems and are evident across all levels of biological organization. Understanding how organisms respond to spatial and temporal variation in temperature, as well as linking their functional responses to temperature, are critical steps toward predicting the responses of populations and communities to global climate change. The southern redbelly dace (Chrosomus erythrogaster) and the central stoneroller (Campostoma anomalum) are two minnows (Cyprinidae) that occur in the Flint Hills region of the United States. These species fill similar ecological roles in streams where they co-occur but differ in their overall pattern of occurrence, with dace largely occupying cooler headwater reaches and stonerollers persisting in both headwaters and warmer intermediate-sized streams. Differences in the fundamental thermal niche of these species could underlie the observed differences in their realized thermal niches along a stream-size gradient of temperature. To better understand how temperature drives patterns of occurrence in functionally similar species of fish, I evaluated the thermal ecology of these two minnow species. First, I tested for interspecific differences in physiological functional traits along an ecologically realistic temperature gradient. The critical thermal maximum of the stoneroller was higher than dace at warm acclimation temperatures, indicating a greater capacity to buffer thermal stress. Additionally, temperature drove differences in activity levels between species |
