在不同条件下,各种中上层鱼类的鱼群几何与鱼群生物量之间的关系具有一定的生物学普遍性,本文建立了鱼群尺寸的标度律:鱼群直径随鱼群生物量的幂函数增加。通过数据折叠提取幂律指数,接近3/5。该指数值表明,随着学校生物量的增加,平均堆积密度减小,堆积结构的质量分形维数为5/3。通过利用学校几何学和聚合物链统计之间的类比,我检验了控制大型中上层生物学校膨胀构象的行为算法,并解释了指数的值。

英文摘要:
Motivated by the finding that there is some biological universality in the relationship between school geometry and school biomass of various pelagic fishes in various conditions, I here establish a scaling law for school dimensions: the school diameter increases as a power-law function of school biomass. The power-law exponent is extracted through the data collapse, and is close to 3/5. This value of the exponent implies that the mean packing density decreases as the school biomass increases, and the packing structure displays a mass-fractal dimension of 5/3. By exploiting an analogy between school geometry and polymer chain statistics, I examine the behavioral algorithm governing the swollen conformation of large-sized schools of pelagics, and I explain the value of the exponent.
