摘要

摘要。Alburnus heckeli Battalgil 1944是幼发拉底河水系（波斯湾流域）哈扎尔湖的特有种，与广泛分布的物种A.sellal Heckel 1843具有相同的形态和分子特征，但据推测，鳃耙的数量除外。本研究比较了A.heckeli与A.sellal的慢和乳液种群的形态计量学和分生组织数据。唯一显著的差异是鞍形A.sellal（10-25）的乳液种群与鞍形A.sellal（26-35）和黑切利A.heckeli（28-35）的慢体种群的鳃耙数量。尽管我们的研究结果与A.heckeli和A.sellal作为“年轻物种”的解释一致，但现有形态学和分子序列数据的模糊性表明，在发现可靠的差异之前，A.checkeli最好被视为A.sellal的初级同义词。

Testing the “young-species” hypothesis for Alburnus heckeli Battalgil 1944 (Teleostei: Leuciscidae) inhabiting Lake Hazar, Turkey

ABSTRACT. Alburnus heckeli Battalgil 1944 is endemic to Lake Hazar in the Euphrates-Tigris River system (Persian Gulf basin) and shares morphological and molecular characters with the widespread species A. sellal Heckel 1843, except putatively for the number of gill rakers. This study compared morphometric and meristic data for A. heckeli with lentic and lotic populations of A. sellal. The only significant difference was in the number of gill rakers in lotic populations of A. sellal (10–25) vs. lentic populations of A. sellal (26–35) and A. heckeli (28–35). Although our results are consistent with the interpretation of A. heckeli and A. sellal as “young species”, the amiguity of available morphological and molecular sequence data suggest that A. heckeli is best treated as a junior synonym of A. sellal until reliable differences are found.
