摘要
Milena Furtula, Ana Ivanovic, Georg Dzukic, and Milos L. Kalezic (2008) Egg size variation in crested newts from the western Balkans (Caudata: Salamandridae: Triturus cristatus superspecies). Zoological Studies 47(5): 585-590, We report herein on egg size characteristics (vitellus volume and jelly/vitellus ratio) of 4 crested newt species (Triturus cristatus superspecies). The key results were as follows: (1) maternal and population effects on these characteristics were detected, however, the species effect was much more pronounced; (2) in terms of the vitellus volume, T karelinii and T macedonicus had the largest eggs, T dobrogicus had the smallest, and T cristatus had eggs of intermediate size; (3) all species significantly differed in their jelly/vitellus ratio values, with the lowest ratio in T macedonicus followed by T karelinii, T cristatus, and T dobrogicus with the highest ratio value: and (4) the species shared a common allometric slope of the egg volume/body size relationship. The egg size traits appeared to follow a evolutionary trend similar to that of the morphological and ecological diversity characteristics. http://zoolstud.sinica.edu.tw/Journals/47.5/585.pdf
