摘要翻译:
我们考虑了海洋保护区之间的最优间距,以使占据保护区网络的物种的生存能力最大化。网络越紧密地放在一起,被占用的保护区对空保护区进行殖民的可能性就越高,从而增加了种群的生存能力。然而,网络越紧密地放在一起,灾难导致两个保护区物种灭绝的可能性就越高,从而降低种群的生存能力。利用一个简单的离散时间马尔可夫链模型来判断物种在每个保护区中的存在与否,我们确定了两个保护区之间的距离,该距离提供了这些过程之间的最优权衡,从而导致物种的最大生存能力。

英文摘要:
We consider the optimal spacing between marine reserves for maximising the viability of a species occupying a reserve network. The closer the networks are placed together, the higher the probability of colonisation of an empty reserve by an occupied reserve, thus increasing population viability. However, the closer the networks are placed together, the higher the probability that a catastrophe will cause extinction of the species in both reserves, thus decreasing population viability. Using a simple discrete-time Markov chain model for the presence or absence of the species in each reserve we determine the distance between the two reserves which provides the optimal trade-off between these processes, resulting in maximum viability of the species.
