动物身体特性之间的异速生长关系可用于各种目的，例如估计生物量、生长、种群结构、生物能量建模和碳通量研究。本文总结了在极地海洋食物网中起主要作用的浮游动物和游泳动物的异速生长关系。在南大洋（冬季和夏季）和北冰洋（春季和夏季）三次考察期间采样的14种2374个人的15种639个人进行测量。这项研究提供的信息填补了目前的知识空白之间的关系的长度和湿/干质量的未充分研究的动物，如各种凝胶状浮游动物，和未充分研究的季节和成熟阶段的动物，例如，在冬季捕获的磷虾Thysanoessa macrura和幼磷虾superba。比较表明，有几个物种的长度质量关系取决于季节，例如，为端足类Themisto libellula种内变异。为了研究广义回归模型的潜在用途，进行了性别、成熟阶段或年龄组之间的比较，并进行了讨论，例如对几种磷虾和T。诽谤回归模型的年龄级比较。anastritica对它们的一般用途没有定论。对甲壳、眼睛、头、尾、尾和耳石进行的其他异速生长测量提供了模型，这些模型被证明可用于估计长度或质量，例如饮食研究。在某些情况下，这些模型的适用性可能取决于物种或发育阶段。在线版本包含补充材料，可通过10.1007/s 00300 -021-02984-4获得。
Allometric relationships between body properties of animals are useful for a wide variety of purposes, such as estimation of biomass, growth, population structure, bioenergetic modelling and carbon flux studies. This study summarizes allometric relationships of zooplankton and nekton species that play major roles in polar marine food webs. Measurements were performed on 639 individuals of 15 species sampled during three expeditions in the Southern Ocean (winter and summer) and 2374 individuals of 14 species sampled during three expeditions in the Arctic Ocean (spring and summer). The information provided by this study fills current knowledge gaps on relationships between length and wet/dry mass of understudied animals, such as various gelatinous zooplankton, and of animals from understudied seasons and maturity stages, for example, for the krill Thysanoessa macrura and larval Euphausia superba caught in winter. Comparisons show that there is intra-specific variation in length–mass relationships of several species depending on season, e.g. for the amphipod Themisto libellula. To investigate the potential use of generalized regression models, comparisons between sexes, maturity stages or age classes were performed and are discussed, such as for the several krill species and T. libellula. Regression model comparisons on age classes of the fish E. antarctica were inconclusive about their general use. Other allometric measurements performed on carapaces, eyes, heads, telsons, tails and otoliths provided models that proved to be useful for estimating length or mass in, e.g. diet studies. In some cases, the suitability of these models may depend on species or developmental stages. The online version contains supplementary material available at 10.1007/s00300-021-02984-4.
