项目摘要

Migration, reproduction, and predator-prey interactions depend heavily on a fish's ability to swim. Swimming efficiency and performance is related to a species' physiology, morphology and behaviour, and the environmental challenges the animal faces (e.g., temperature changes, velocity changes). The focus of my research program is to understand the influence of various abiotic and biotic factors on the swimming capacity and energetics of the sturgeon, a "primitive fish." The rationales for utilizing the sturgeon as a model are many-fold, including: (i) biological, because of its intermediate evolutionary position between sharks and teleosts; (2) their excellent capacity to deal with acute and chronic stressors; (3) commercial, owing to their highly-prized meat and caviar; (4) conservation, as many populations of sturgeon are considered to be critically endangered due to overharvesting and habitat degradation/encroachment. Our recent findings show that sturgeon possess unique morphological and behavioural attributes that affect their swimming patterns (e.g., station-holding) and performance (e.g., length of time swimming). My long-term objective is to address the interplay of behaviour, morphology and physiology on the metabolic costs of swimming in sturgeon. The short-term goals here focus on the costs of transport, swimming efficiency, and metabolic fuel use patterns (i.e., whether they use carbohydrates, lipids or proteins) at different speeds and temperatures in shortnose sturgeon. In addition, I will examine the metabolic costs of repeat swimming challenges and the importance of light levels on swimming performance in sturgeon. The proposed experiments, using swim flume technology, are designed to test novel hypotheses with regard to metabolic costs associated with swimming in a primitive fish. My research program is original in that many swimming studies focus on high-performance species, such as salmon and trout. In contrast, sturgeons are slow-moving, bottom-feeding fishes, but more information is needed to better understand the factors that affect swimming in these primitive fishes. Such knowledge would provide invaluable insight into how locomotion evolved in vertebrates. In the global sense, my research has both basic (e.g., exercise physiology) and applied (e.g., global warming issues, migration costs, stocking strategies) importance. Obstacles to migration, such as dams and water diversions, can block or impede sturgeon migration and reproduction. Such obstacles, combined with climate change, can also affect water temperatures and flows. Thus, my work will help to define the physiological limits of these ancient fish in response to human activities and global climate change.
迁移、繁殖和捕食者与猎物的相互作用在很大程度上取决于鱼的游泳能力。游泳效率和表现与物种的生理、形态和行为以及动物面临的环境挑战有关(例如,温度变化、速度变化)。我的研究计划的重点是了解各种非生物和生物因素对鲟鱼(一种“原始鱼类”)的游泳能力和能量学的影响。“利用鲟鱼作为模型的理由是多方面的,其中包括:㈠生物方面的,因为鲟鱼在进化上处于鲨鱼和硬骨鱼之间的中间位置; ㈡鲟鱼处理急性和慢性应激源的能力极佳; ㈢商业方面的,因为鲟鱼的肉和鱼子酱价值很高;(4)保护,由于过度捕捞和生境退化/侵蚀,许多鲟鱼种群被认为是极度濒危的。我们最近的研究结果表明,鲟鱼具有独特的形态和行为属性,影响他们的游泳模式(例如,站保持)和性能(例如,游泳的时间()我的长期目标是解决行为,形态和生理的相互作用对鲟鱼游泳的代谢成本。这里的短期目标集中在运输成本、游泳效率和代谢燃料使用模式(即,无论它们使用的是碳水化合物、脂质还是蛋白质)。此外,我将研究重复游泳挑战的代谢成本和光照水平对鲟鱼游泳表现的重要性。拟议的实验使用游泳水槽技术,旨在测试有关原始鱼游泳相关代谢成本的新假设。我的研究计划是原创的,因为许多游泳研究都集中在高性能的物种上,如鲑鱼和鳟鱼。相比之下,鲟鱼是缓慢移动,底部进食的鱼类,但需要更多的信息来更好地了解影响这些原始鱼类游泳的因素。这些知识将为了解脊椎动物的运动是如何进化的提供宝贵的见解。在全球范围内,我的研究既有基本的(例如,运动生理学)和应用(例如,全球变暖问题,迁移成本,放养策略)的重要性。迁移的障碍,如水坝和引水,可以阻止或阻碍鲟鱼的迁移和繁殖。这些障碍加上气候变化,也会影响水温和水流。因此,我的工作将有助于确定这些古老鱼类在应对人类活动和全球气候变化方面的生理极限。
