我们调查了更新世期间海洋动物多样性的变化是否会受到海平面变化的影响。我们的估计之间的低立场和高立场的海平面（约200米）的浅海海域的变化，导致预测约25%的物种多样性的变化，10%的变化，在属的多样性和不到5%的变化，在家庭的多样性。这与大规模的属或科的变化没有被广泛注意到更新世的观察。与其他地质时期一样，由于海平面的变化而造成的动物区规模的变化，与动物区数量的变化相比，不太可能成为改变海洋多样性的重要因素。
We have investigated whether changes in marine faunal diversity during the Pleistocene would have been affected by changes in sea level. Our estimate of changes in area of shallow marine seas between low stand and high stand of sea level (approximately 200 m) leads to a prediction of approximately a 25% change in species diversity, 10% change in generic diversity and less than a 5% change in familial diversity. This agrees with the observation that large scale generic or familial changes have not been widely noted for the Pleistocene. As in other intervals of geologic time, changes in the sizes of faunal provinces owing to changes in sea level are less likely to be the significant factor in changing marine diversity than are changes in the number of faunal provinces.
