确定了俄克拉荷马州中北部的6级间歇性系统水獭溪流域的河流秩序与鱼类物种多样性之间的关系。8个月后收集鱼。在严重干旱和连续流2或3天的溪流之后再次出现。共采集鱼类20种。两个集合的物种多样性值非常相似。物种多样性随河流阶次的增加而增加，相关系数为0.96。讨论了干旱和油田卤水流入的影响。
The relation between stream order and species diversity of fishes in the Otter Creek drainage basin, a 6th-order intermittent system in north-central Oklahoma, was determined. Fishes were collected after 8 mo. of continuous stream flow and again after a severe drought and 2 or 3 days of stream flow. Twenty species of fishes were collected. Species diversity values for both collections were remarkably similar. Species diversity increased progressively with stream order and the correlation coefficient between stream order and species diversity was 0.96. Effects of drought and influx of oil field brines are discussed.
