Natural incidence of body abnormalities in the Montseny newt, Calotriton arnoldi Carranza and Amat, 2005
The decline and wealth of amphibian populations is a recurrent centre of interest in the herpetological scientific community since the past eight decades. One of the most worrisome phenomena is the spread of morphological malformations, especially in frogs, but also occasionally in salamanders (Sequeira et al., 1999; Wheeler, McCallum and Trauth, 2002; Ferrer and Lopez, 2003; Miller and Miller, 2005). The Montseny newt (Calotriton arnoldi) is one of the most recent described amphibian species in Europe (Carranza and Amat, 2005). Restricted to a small range within the Montseny massif (north eastern Iberian Peninsula), only seven populations structured into two separated areas by a river (Tordera river), are actually known. Population in these two areas, divided in eastern and western, are genetic and morphologically well differentiated (Valbuena-Ureña, Amat and Carranza, 2013). Calotriton asper is an entirely aquatic species, living in fast flowing steams in forestal areas from 650 m to 1.200 m.a.s.l. In the course of conservation surveys carried out in the Natural Park of Montseny, we detected some individuals affected by limb abnormalities in one population of C. arnoldi . Consequently we performed an especific survey to characterize and quantify the incidence of body abnormalities on C. arnoldi. .
