-------- Original Message -------- Subject: New publication: Geometric morphometrics for any type of symmetry Date: Tue, 8 Nov 2011 08:09:55 -0500 From: Yoland SAVRIAMA <[email protected]> To: [email protected] Dear all, I wanted to draw attention on a paper that Chris Klingenberg and I recently published: Savriama and Klingenberg: Beyond bilateral symmetry: geometric morphometric methods for any type of symmetry. BMC Evolutionary Biology 2011 11:280. doi:10.1186/1471-2148-11-280 Studies of symmetric structures have made important contributions to evolutionary biology, for example, by using fluctuating asymmetry as a measure of developmental instability or for investigating the mechanisms of morphological integration. So far, most of the studies dealt with the analysis of symmetry and asymmetry in bilaterally symmetric structures. However, other types of symmetry exist as well (e.g., radial symmetry in many flowers and sea urchins or biradial symmetry in many algae and flowers). In this paper, we introduce a new general approach for shape analysis of structures with any type of symmetry. We illustrate this approach with data from a colonial coral that has ambiguous symmetry and use this special property to analyze different types of symmetry associated with it. Best wishes, Yoland SAVRIAMA
