Fluctuating Asymmetry in the Eurasian Spur-Thighed Tortoise, Testudo graeca ibera Linneaus, 1758 (Testudines: Testudinidae)


Băncilă, Raluca Ioana; Plăiaşu, Rodica; Tudor, Marian; Samoilă, Ciprian; Cogălniceanu, Dan (2012). Fluctuating Asymmetry in the Eurasian Spur-Thighed Tortoise, Testudo graeca ibera Linneaus, 1758 (Testudines: Testudinidae). Chelonian Conservation and Biology, 11(2):234-239.

Abstract

We studied plastron-shaped asymmetry of the Eurasian Spur-Thighed Tortoise, Testudo graeca ibera, as related to life stage, gender, and distribution. Our analyses of 523 individuals showed that fluctuating asymmetry (FA) in plastron shape varied with gender (males exhibited higher levels of FA than did females) and across populations, whereas life stage had no significant effect. Although we could not identify the potential sources of variation responsible for the observed patterns of developmental instability, our study shows the value of FA as a method for studies of developmental instability in turtles.

TrendTerms

TrendTerms displays relevant terms of the abstract of this publication and related documents on a map. The terms and their relations were extracted from ZORA using word statistics. Their timelines are taken from ZORA as well. The bubble size of a term is proportional to the number of documents where the term occurs. Red, orange, yellow and green colors are used for terms that occur in the current document; red indicates high interlinkedness of a term with other terms, orange, yellow and green decreasing interlinkedness. Blue is used for terms that have a relation with the terms in this document, but occur in other documents.
You can navigate and zoom the map. Mouse-hovering a term displays its timeline, clicking it yields the associated documents.
