Different environmental conditions may lead to diverse morphological, behavioral, and physiological adaptations of different populations of the same species. Lighting conditions, for example, vary vastly especially between aquatic habitats, and have been shown to elicit adaptations. The availability of short-wave ultraviolet (UV) light is especially fluctuating, as UV wavelengths are attenuated strongly depending on water properties. The island of North Uist, Scotland, comprises 2 differential habitat types, tea-stained and clear-water lakes, varying considerably in UV transmission. In previous studies, wild-caught 3-spined stickleback Gasterosteus aculeatus populations (3 populations of each habitat type) were tested with respect to their shoaling and mate preferences for fish viewed under UV-present and UV-absent conditions. The results revealed a habitat-dependent preference of UV cues during shoal choice (tea-stained populations: preference for UV-absent condition in tea-stained water; clear-water populations: no preference in clear-water) but an overall preference for UV-present conditions during mate choice. To assess genetic influences on these behavioral patterns, similar experiments were conducted with lab-bred F1-generations of the same stickleback populations that were raised in a common environment (i.e. standardized clear-water conditions). Offspring of sticklebacks from tea-stained lakes tended to prefer shoals viewed under UV-absent conditions (only in tea-stained water), while sticklebacks from clear-water lakes showed a significant preference for the shoal viewed under UV-present conditions in clear-water but not in tea-stained water. Mate-preference experiments demonstrated that females from the tea-stained lakes significantly preferred and females from the clear-water lakes preferred by trend the male viewed under UV-present conditions in the clear-water treatment. The results for both shoaling- and mate-preference tests were largely similar for wild-caught and lab-bred sticklebacks, thus hinting at a genetic basis for the preference patterns.

照明环境对来自两种不同光生境的刺鱼社会偏好的影响。二、实验室养殖鱼类的浅滩和交配偏好

不同的环境条件可能会导致同一物种不同种群的形态、行为和生理适应不同。例如,光照条件差异很大,尤其是在水生栖息地之间,并且已被证明会引起适应。短波紫外线 (UV) 光的可用性尤其波动,因为紫外线波长会根据水的特性强烈衰减。苏格兰的北尤伊斯特岛由 2 种不同的栖息地类型组成,茶色湖泊和清水湖泊,紫外线透射率差异很大。在之前的研究中,野生捕捞的三刺Gasterosteus aculeatus在有紫外线和无紫外线的条件下观察鱼类的浅滩和交配偏好,对它们的种群(每种栖息地类型的 3 个种群)进行了测试。结果揭示了在浅滩选择期间紫外线线索的栖息地依赖性偏好(茶渍种群:偏好在茶渍水中无紫外线条件;清水种群:不偏好清水)但总体偏好紫外线-配偶选择期间的现状。为了评估遗传对这些行为模式的影响,对实验室培育的 F1 代相同刺鱼种群进行了类似的实验,这些种群在共同环境(即标准化的清水条件)中饲养。来自茶渍湖泊的刺鱼的后代往往更喜欢在没有紫外线的条件下观看的浅滩(仅在茶渍水中),而来自清水湖泊的刺鱼对在紫外线存在条件下的清水中观察到的浅滩表现出显着的偏好,但在茶渍水中则不然。配偶偏好实验表明,在清水处理中,在紫外线存在条件下观察到的趋势,来自茶染湖的雌性显着偏爱,而来自清水湖的雌性则更喜欢雄性。对于野生捕捞和实验室培育的刺鱼,浅滩和配偶偏好测试的结果在很大程度上相似,因此暗示了偏好模式的遗传基础。配偶偏好实验表明,在清水处理中,在紫外线存在条件下观察到的趋势,来自茶染湖的雌性显着偏爱,而来自清水湖的雌性则更喜欢雄性。对于野生捕捞和实验室培育的刺鱼,浅滩和配偶偏好测试的结果在很大程度上相似,因此暗示了偏好模式的遗传基础。配偶偏好实验表明,在清水处理中,在紫外线存在条件下观察到的趋势,来自茶染湖的雌性显着偏爱,而来自清水湖的雌性则更喜欢雄性。对于野生捕捞和实验室培育的刺鱼,浅滩和配偶偏好测试的结果在很大程度上相似,因此暗示了偏好模式的遗传基础。
