Collaborative Research Linking behavior transport

项目摘要

Many bottom-dwelling marine species have larvae whose behavior in the water column impacts dispersal and adult distributions. Snail larvae swim up with more effort or sink in response to cues from waves and turbulence, and it remains unclear whether larvae can use these physical cues for retention within or navigation among habitats. Larvae that swim up under waves may be retained over the continental shelf by wave-induced shoreward drift in surface waters. However, ocean warming causes larvae to be released earlier in spring when waves are larger and coastal upwelling is weaker, potentially carrying larvae into shallower waters that exceed the adults' temperature tolerance. The investigators will use a physical model of the Middle Atlantic Bight and adjacent estuaries to test hypotheses about how waves and turbulence affect transport patterns, retention near adult habitats, and climate-induced shifts in adult distributions. The project will produce simulations of ocean circulation and larval tracking codes that include waves both as behavior cues and as a transport mechanism; these products will be made publicly available. A graduate student will do a related dissertation. Undergraduate students will be involved through an NSF-funded REU program, the Aresty Program, which engages Rutgers' diverse undergraduates in research to boost retention in STEM majors, the Rutgers Research in Science and Engineering program, which targets underrepresented minorities, and the Skidmore Summer Research program. Model outputs will be used to develop learning materials for undergraduates, packaged as a case study for distribution through the National Center for Case Study Teaching in Science. Research results will also be presented to adult (55 and over) learners through the Skidmore Encore lecture series.Waves are unique in providing planktonic larvae with a behavior cue directly tied to a horizontal transport mechanism, and newly discovered larval responses to waves could have counter-intuitive impacts on larval transport and species distributions. Wave climates differ in the adjacent habitats of two congeneric snails: Tritia obsoleta occupies turbulent inlets and estuaries where waves are small, while Tritia trivittata occupies the continental shelf where waves are much larger. These two species' larvae sense waves and turbulence separately as acceleration and vorticity-induced body rotation, respectively. Late-stage estuarine larvae mainly exhibit turbulence-induced sinking that could reduce transport out of inlets and estuaries, whereas shelf larvae also exhibit wave-induced upward swimming that could aid retention over the shelf via Stokes drift. Since the 1960s, the shelf species' range has shifted into warmer water, opposite to predictions based on thermal tolerance. This shift may be driven by wave-induced larval transport; as ocean warming induces earlier spawning, larvae will encounter larger waves and weaker upwelling in spring, intensifying Stokes drift and onshore transport toward warmer, shallower waters of the inner shelf. The project will use numerical models to test hypotheses linking flow-induced larval behaviors to transport pathways, local retention, and climate-driven range shifts. Waves will be included as a source of both behavior cues and advection through acceleration and Stokes drift, respectively. Results will help resolve uncertainties about how Stokes drift, Eulerian return flow, and upwelling interact to transport larvae. Numerical experiments will describe how climate-driven changes in spawning phenology affect larval transport, potentially identifying the mechanism behind perplexing range shifts of shelf species into warmer water.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

许多底栖海洋物种的幼虫在水体中的行为会影响其扩散和成虫分布。蜗牛幼虫响应波浪和湍流的提示，会更加努力地向上游动或下沉，目前尚不清楚幼虫是否可以利用这些物理提示在栖息地内停留或在栖息地之间导航。在波浪下游泳的幼虫可能会因波浪引起的地表水域向岸漂移而保留在大陆架上。然而，海洋变暖导致幼虫在春季释放得更早，此时波浪更大，沿海上升流更弱，可能会将幼虫带入超出成虫温度耐受性的浅水区。研究人员将使用中大西洋湾和邻近河口的物理模型来测试有关波浪和湍流如何影响运输模式、成虫栖息地附近的滞留以及气候引起的成虫分布变化的假设。该项目将模拟海洋环流和幼虫跟踪代码，其中包括波浪作为行为线索和运输机制；这些产品将公开提供。研究生将完成相关论文。本科生将通过 NSF 资助的 REU 项目、Aresty 项目（该项目让罗格斯大学的多元化本科生参与研究以提高 STEM 专业的保留率）、罗格斯大学科学与工程研究项目（针对代表性不足的少数族裔）以及斯基德莫尔夏季项目（Skidmore Summer）参与其中。研究计划。模型输出将用于开发本科生学习材料，打包为案例研究，通过国家科学案例研究教学中心分发。研究结果还将通过斯基德莫尔安可系列讲座向成人（55 岁及以上）学习者展示。波浪的独特之处在于为浮游幼虫提供了与水平运输机制直接相关的行为线索，新发现的幼虫对波浪的反应可能会产生相反的效果。 -对幼虫运输和物种分布的直观影响。两种同属蜗牛的相邻栖息地的波浪气候有所不同：Tritia obsoleta 占据波浪较小的湍流入口和河口，而 Tritia trivittata 占据波浪大得多的大陆架。这两个物种的幼虫分别将波浪和湍流感知为加速度和涡流引起的身体旋转。晚期河口幼体主要表现出湍流引起的下沉，这可能会减少从入口和河口的运输，而陆架幼体也表现出波浪引起的向上游动，这可能有助于通过斯托克斯漂流滞留在陆架上。自 20 世纪 60 年代以来，陆架物种的活动范围已转移到较温暖的水域，这与基于耐热性的预测相反。这种转变可能是由波浪引起的幼虫运输驱动的；由于海洋变暖导致产卵提前，幼虫在春季会遇到更大的波浪和更弱的上升流，从而加剧斯托克斯漂流和向内陆架较温暖、较浅水域的陆上运输。该项目将使用数值模型来测试将流动引起的幼虫行为与运输路径、局部保留和气候驱动的范围变化联系起来的假设。波浪将分别作为行为线索和平流通过加速和斯托克斯漂移的来源。结果将有助于解决斯托克斯漂移、欧拉回流和上升流如何相互作用以运输幼虫的不确定性。数值实验将描述气候驱动的产卵物候变化如何影响幼虫运输，有可能确定陆架物种向温暖水域的复杂范围转变背后的机制。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力评估进行评估，被认为值得支持。优点和更广泛的影响审查标准。
