Morphometric variation in two intertidal littorinid gastropods
Queiroga, Henrique; Costa, Rolando; Leonardo, Nélia; Soares, Débora; Cleary, Daniel F. R.Here we investigate spatial variation in shell shape of Littorina saxatilis, an ovoviviparous species, and Melarhaphe neritoides, a species with planktonic eggs and larvae. Populations of both species were sampled in 6 sites located along the west coast of the Iberian Peninsula. Shell shape was studied using landmarkbased morphometric methods. Landmark data was used to estimate individual size and to describe s...
