项目摘要
Evolutionary ecologists seek to understand (1) how organisms adapt to changing environments and (2) how broad scale patterns of morphological variation reflect such adaptation. Until recently, morphological variation within species has been interpreted as adaptation due to natural selection rather than environmentally induced (ecophenotypic) phenomena. However, it is increasingly clear that morphological variation within species can also reflect the developmental response of an organism to its environment (phenotypic plasticity). Among the best documented examples of adaptive phenotypic plasticity are predator-induced defensive responses in prey. Recent experiments have shown that snails can reduce their vulnerability to crab predators by altering shell form (e.g., thickening shells) in response to water-borne chemical cues (effluent) from crabs. Colder water temperatures, however, increase the rate at which shell material dissolves and, thus, could profoundly affect the degree, effectiveness, and cost of this defensive response. The PIs wish to determine how snail populations respond to the interacting environmental cues of crab effluent and water temperature. The historical and geographic relationship of the smooth periwinkle snail Littorina obtusata and the introduced green crab Carcinus maenas in the Gulf of Maine provides an outstanding system to test these objectives. The PIs earlier work has shown that smooth periwinkles in the northern Gulf have thicker shells than in the southern Gulf and that shell thickness of snails increases in response to green crab effluent. Water temperature and green crab abundances are both higher in the southern than in the northern Gulf of Maine and, thus, could influence snail shell form separately or in concert. To determine the relative contribution of crab effluent and water temperature to snail shell form, the PIs will conduct a field experiment that manipulates levels of each cue. Half of a group of juvenile northern snails will be moved to a southern site, while the remainder are left in their native site. Similarly, half of a group of juvenile southern snails will be moved to the northern site, while the remainder are left at the southern site. The PIs will compare shell thickness and body growth among snails transplanted between northern and southern populations and those reared in their native environments. For each population in each location, half of the snails will be exposed to crab effluent and the other half will not. These experiments will help us understand the effects of environmental and genetic influences on resulting shell and body form as well as the relative importance of each cue. In a second experiment, trade-offs between body size, growth rate, reproductive success and shell thickness will be examined in the laboratory using a similar reciprocal design. Egg masses will be cultured from 2 northern and 2 southern populations, and the hatchlings will be raised in temperature-controlled incubators. Each population will be subjected to 2 water temperatures and 2 crab treatments (with, without effluent). Upon reaching maturity, female snails will be allowed to mate and lay eggs. These experiments will identify life history trade-offs associated with predator-induced change in shell form at each temperature. In a third set of experiments, the effectiveness of the induced response in reducing vulnerability to crab predation will be tested by comparing handling times and techniques and foraging success of green crabs on the snails derived from the laboratory experiments. Finally, the PIs will survey green crab and smooth periwinkle populations at multiple sites in the Gulf of Maine to test for geographic and seasonal associations between snail shell thickness and crab abundance. Results from this project will provide a better understanding of (1) the relative importance of genetic vs. environmentally induced phenomena and (2) contributions of two ubiquitous environmental cues (predators, temperature) in producing broad scale morphological variation. These issues are particularly germane, because (1) anticipated changes in global climate will alter water temperatures locally and regionally and (2) temperature-related range expansions and human-mediated introductions will expose native prey populations to novel predators.
进化生态学家试图理解(1)生物如何适应不断变化的环境,(2)形态变异的大尺度模式如何反映这种适应。 直到最近,物种内的形态变异一直被解释为适应由于自然选择,而不是环境引起的(生态表型)现象。 然而,越来越清楚的是,物种内的形态变化也可以反映生物体对其环境的发育反应(表型可塑性)。 适应性表型可塑性的最好的例子是捕食者诱导的猎物防御反应。 最近的实验表明,蜗牛可以通过改变外壳形状(例如,外壳变厚),以响应螃蟹的水生化学线索(流出物)。 然而,较冷的水温会增加外壳材料溶解的速度,因此可能会深刻影响这种防御反应的程度,有效性和成本。PI希望确定蜗牛种群如何对螃蟹流出物和水温的相互作用的环境线索作出反应。 历史和地理关系的平滑的长春花蜗牛Littorina obtusata和引进的绿色螃蟹Carcinus maenas在缅因州湾提供了一个优秀的系统来测试这些目标。PI早期的工作表明,在北方海湾的平滑长春花比南部海湾的贝壳更厚,蜗牛的贝壳厚度增加,以应对绿色螃蟹的流出物。 水温和绿色蟹丰度都是在南部高于北方海湾的缅因州,因此,可能会影响蜗牛壳的形式单独或在音乐会。 为确定螃蟹排泄物和水温对蜗牛壳形态的相对影响,PI将进行现场实验,操纵每种线索的水平。 一群北方幼螺的一半将被移到南方的一个地点,而其余的则留在它们的原居地。 同样地,一组南部幼螺的一半会被移到北方的地点,而其余的则留在南部的地点。 PI将比较北方和南方种群之间移植的蜗牛与在其原生环境中饲养的蜗牛之间的壳厚度和身体生长。 对于每个地点的每个种群,一半的蜗牛将暴露于螃蟹的污水中,另一半则不会。 这些实验将帮助我们了解环境和遗传因素对最终壳和身体形态的影响,以及每个线索的相对重要性。 在第二个实验中,将在实验室中使用类似的互惠设计来检查身体大小、生长速率、繁殖成功率和壳厚度之间的权衡。 将从2个北方种群和2个南方种群中培养卵块,并将在温控孵化器中饲养孵化的幼仔。 每个种群将接受2种水温和2种螃蟹处理(有、无污水)。 当雌性蜗牛成熟后,将允许交配和产卵。 这些实验将确定在每个温度下与捕食者引起的外壳形式变化相关的生活史权衡。 在第三组实验中,诱导反应在减少螃蟹捕食的脆弱性方面的有效性将通过比较处理时间和技术以及绿色蟹对来自实验室实验的蜗牛的觅食成功率来测试。 最后,PI将在缅因州海湾的多个地点调查绿色螃蟹和平滑的长春花种群,以测试蜗牛壳厚度和螃蟹丰度之间的地理和季节关联。 该项目的结果将提供更好的理解(1)遗传与环境诱导现象的相对重要性和(2)两个无处不在的环境线索(捕食者,温度)在产生大规模形态变异中的贡献。这些问题特别密切相关,因为(1)全球气候的预期变化将改变当地和区域的水温,(2)与温度相关的范围扩张和人为介导的引入将使本地猎物种群暴露于新的捕食者。
