Abstract

The paper analyzes the morphological diversification of individuals of the generalized form of the Barbus intermedius complex in comparison with the diversification of specialized morphotypes and allopatric species of large African barbs. In the sets of generalized individuals, four main vectors of diversification are revealed, while two each are revealed in morphotypes and species. Comparison of peer-to-peer diversification vectors of monomorphic populations of generalized individuals from Langano and Awasa lakes reveals their similarity and essential differences from the corresponding diversification vectors of generalized individuals from Lake Tana. The vectors of diversification of the Lake Tana morphotypes are very similar to both peer-to-peer vectors of allopatric species and to the vectors of the Lake Tana generalized form. This high degree of similarity suggests that the diversification of individuals of the generalized form in Lake Tana, diversification of the Tana morphotypes, and diversification of allopatric species are successive stages of one process, and diversification of morphotypes and species proceeds in the directions specified by diversification of individuals of a generalized form. The results of the study may be considered as strong evidence in favor of the hypothesis of proximity (or identity) of a generalized form and the ancestral form, which gave rise to the diversity of the B. intermedius complex. The study is based on the assessment of correlations between the characters of individuals of the studied sets.

非洲大倒钩：广义形式的个体的多样化载体，作为埃塞俄比亚塔纳湖中间巴氏复合体物候多样性的来源

摘要

本文分析了中间巴氏虫的广义形式的个体的形态多样性与大型非洲倒钩的特殊形态型和异源物种的多样化相比，它的复杂性更高。在广义个体的集合中，揭示了四个主要的多样化载体，而在形态类型和种类上分别揭示了两个。从Langano和Awasa湖的广义个体单态种群的点对点多样化向量的比较显示，它们与塔纳湖的广义个体的相应多样化向量的相似性和本质区别。塔纳湖形态型的多样化载体与异源物种的对等载体和塔纳湖广义形式的载体都非常相似。这种高度的相似性表明，塔纳湖中广义形式个体的多样化，Tana形态类型的多样化和异源物种的多样化是一个过程的连续阶段，形态类型和物种的多样化朝着广义形式个体多样化所指定的方向发展。研究的结果可以被视为有力的证据，支持了广义形式和祖先形式的接近性（或同一性）假说，这导致了形式的多样性。B. intermedius复合体。该研究是基于对研究对象个体特征之间相关性的评估。
