Effect of geographic location and sexual dimorphism on shield shape of the Red Sea hermit crab Clibanarius signatus using geometric morphometric approach.
The hermit crab _Clibanarius signatus_ Heller,1861, inhabits varied intertidal habitats of the Red Sea coast, such as rocky shores and mangrove littoral salt marshes. Shield-shape variation among three populations of _C. signatus _was analyzed with geometric morphometric methods. Shape variation was studied through multivariate analyses using configurations aligned by the generalized Procrustes analysis. Shape variation was explored through principal component ... Read more
