众所周知，在动物地理范围的极限，其丰度和确切边界可能会不时波动。这些波动有时可能与环境变化有关，因此可能有助于评估控制分布的因素的相对重要性。例如，常见的潮间带藤壶Chthalus stellatus（Poli）和Balanus balanoides（Linnaeus）的分布发生了变化，这归因于几年来温度的普遍上升（Southward & Crisp，1954 a）。自1951-52年以来，这些藤壶的丰度进一步波动，我们现在能够更密切地分析人口变化与环境变化之间的关系。
It is well known that towards the limits of an animal's geographical range both its abundance and exact boundaries may fluctuate from time to time. These fluctuations can sometimes be correlated with environmental changes, and thus may help to assess the relative importance of the factors that control distribution. For example the distribution of the common intertidal barnacles Chthamalus stellatus (Poli) and Balanus balanoides (Linnaeus) underwent changes which were attributed to a general rise in temperature over several years (Southward & Crisp, 1954a). The abundance of these barnacles has fluctuated further since 1951–52, and we are now able to analyse more closely the relation between the population changes and environmental variations.
