Accurate estimations of population size and space-use are critical issues, for assessing population trends and extinction risk. In this study, we applied spatially explicit capture-recapture (SECR) modelling customized for linear habitats to a three-year Capture-Mark-Recapture (CMR) monitoring of three populations of stream-dwelling Pyrenean brook newt (Calotriton asper), an endemic species of the Pyrenean mountain range.

Durante el año 2019 se realizaron prospecciones en diferentes puntos de agua de la comarca del Vallès Oriental susceptibles de albergar poblaciones de galápagos autóctonos y con la finalidad de realizar un estudio poblacional en alguna de ellas. Avalado por la Sociedad Herpetológica Valenciana, ese mismo año se inició un estudio poblacional sobre la comunidad de galápagos que habitan en el ENIM de Can Cabanyes, identificándose un total de 78 galápagos autóctonos y retirándose del medio un total de 44 ejemplares de galápagos exóticos.
