Abstract

The aim of this study was to find the location of a breakpoint in the weight–length relationship using a linearized biexponential model (LinBiExp). The analysis was performed using weight and length measurements of bleak (Alburnus alburnus) individuals captured in freshwaters of the Province of Ferrara (Italy). The LinBiExp function identified the breakpoint coordinates in the data set. The level of uncertainty in the breakpoint coordinates was analysed using bootstrap regression. Bilinearity was verified by comparing slopes and intercepts (ANCOVA) of the two linear sections. The study confirmed that LinBiExp can be a valuable tool for detecting the coordinates of a breakpoint in weight–length data.

苍凉(Alburnus Alburnus)的双峰重长关系

本研究的目的是使用线性化双指数模型（LinBiExp）来寻找权长关系中断点的位置。该分析使用在费拉拉省淡水湖捕获的惨淡（Alburnus Alburnus）个体的重量和长度测量进行。LinBiExp函数标识了数据集中的断点坐标。使用bootstrap回归分析断点坐标中的不确定性水平。通过比较两个线性截面的斜率和截距（ANCOVA）来验证双线性。该研究证实，LinBiExp可以成为检测重量-长度数据中断点坐标的一个有价值的工具。

期刊介绍： Annales Zoologici Fennici publishes mainly original research reports, but also in-depth reviews and commentaries on all aspects of animal ecology and evolution, and fields related to them. Our aim is to promote papers which focus on the interactions among various components in the past and present environments by using integrative and cross-disciplinary approaches. This may be achieved by employing tools from different fields of research, such as (but not restricted to): ecology and paleoecology, molecular ecology and phylogeography, conservation biology, human-induced contemporary evolution and wildlife management, animal behaviour and interactions (including recognition systems and mechanisms), paleontology (except systematics and taxonomy) and evolution, bioenergetics.
