Evolutionary Ecology and Conservation Biology of Fishes

我的研究重点是自然种群内和自然种群之间生殖策略的巨大差异。这种生活史的差异可以通过个体在年龄和成熟时的大小、每只雌性的产卵量和后代大小上的差异来反映。这种可变性的来源在多大程度上是遗传的、环境的或它们的某种组合？这是进化生态学和保护生物学的一个基本问题。首先，变异的来源决定了生活史对环境扰动(如栖息地改变和收获)的反应是快速还是缓慢，甚至根本不会发生。其次，生活史反应的性质，即环境变化引起的生殖策略的变化，可能会影响种群从崩溃中恢复、在时间中坚持和维持剥削的能力。

My research focuses on the tremendous variability in reproductive strategies within and among natural populations. Such life history variation can be reflected by individual differences in age & size at maturity, number of eggs per female, and offspring size. To what extent is the source of this variability genetic, environmental, or some combination thereof? This is a fundamental question to evolutionary ecology and conservation biology. Firstly, the source of variation determines whether life history responses to environmental perturbations, such as habitat alteration and harvesting, will be rapid, slow, or indeed whether they will occur at all. Secondly, the nature of the life history response, i.e., the change in reproductive strategy produced by the environmental change, can affect a population's ability to recover from collapse, persist through time, and sustain exploitation.
