Behavioural physiology and fitness of anadromous migraiting fish

我的研究小组率先调查了不断变化的迁徙环境对野生鲑鱼的能量利用、成熟和压力的作用，但很少有研究关注这种变化对健康的影响。我们将使用大型围隔实验来研究几个具体的假设，涉及能量，疾病，生理应激，水温和游泳行为的作用，在个人层面上，成熟，产卵，衰老，卵丰度，孵化成功，后代的生存，生长和性能。有相当大的变异性内和种群之间的迁移成功，并在生产的少年鲑鱼，不能简单地考虑成年人的产卵场。我们的工作应考虑到成年人移徙环境的重要性，以及成年人对环境挑战的反应对其少年的数量、质量和生存能力的重要性。更好地了解这种代际影响对于了解气候变化如何影响野生溯河产卵种群以及鲑鱼及其栖息地的管理也至关重要。

My research group has pioneered investigations into the role that changing migratory environments have on energy use, maturation and stress in wild salmon, however little research has focused on the fitness consequences of such changes. We will use large mesocosm experiments to examine several specific hypotheses involving the role of energy, disease, physiological stress, water temperature, and swimming behaviours, at the individual level, on maturation, spawning, senescence, egg abundance, hatching success, and offspring survival, growth and performance. There is considerable variability within and among populations in migration success, and in production of juvenile salmon which cannot be explained by simple considerations of number of adults on spawning grounds. Our work should put into context the importance of the adult migration environment, and of adult response to environmental challenges, to the abundance, quality and survivability of their juveniles. A better understanding of such intergenerational effects is also critical for understanding how climate change is and will continue to affect wild anadromous populations, and for the management of salmonids and their habitats.
