The Atlantic-Mediterranean marine transition is characterised by strong oceanographic barriers and steep environmental gradients that generally result in connectivity breaks between populations from both basins and may lead to local adaptation. Here, we performed a population genomic study of the black brittle star, Ophiocomina nigra, covering most...

Se describe un nuevo caso de consumo de anfibios, esta vez de rana verde (Pelophylax sp.) por cangrejo azul (Callinectes sapidus), lo que constituye una nueva amenaza a este grupo faunístico. Este caso se suma a los múltiples impactos negativos sobre la biodiversidad autóctona y la economía local, que nos lleva a sugerir la inclusión del cangrejo a...

The chytrid fungus Batrachochytrium dendrobatidis has caused the most prominent loss of vertebrate diversity ever recorded, which peaked in the 1980s. Recent incursion by its sister species B. salamandrivorans in Europe raised the alarm for a new wave of declines and extinctions in western Palearctic urodeles. The European Commission has responded...

Biosecurity, an Essential Tool for Amphibians’ Conservation The detection in the last two years of highly-infective amphibian pathogens in a few localities in El Montnegre i el Corredor Nature Park has triggered all the alarms, making it necessary to modify the amphibian monitoring protocols in order to prevent their dispersal to other localities...

Managing an Amphibian Population in El Montnegre i el Corredor Park to Contain and Eliminate an Outbreak of the Fungus Batrachochytrium salamadrivorans (Bsal) In 2018, the chytrid fungus Batrachochytrium salamandrivorans (Bsal) was detected in a reservoir in El Montnegre i el Corredor Park, resulting in a high mortality rate of the marbled newt (T...

Distribution, Systematics and Origin of Amphibian Species Introduced into El Montnegre i el Corredor Nature Park Over the past decades, over-exploitation, habitat loss, the introduction of invasive species, pollution and, more recently, climate change and emerging diseases have led to a catastrophic decline in the number and size of vertebrate spe...

In our study, individuals of both green frogs from the Iberian Peninsula have been captured. Measure-ments of different morphology characteristics have been taken. The results show significant differences being appreciable in the distance between the snout and cloaca, the left rear extremity length, occular diameter and the eardrum diameter. All of...

Tres noves aportacions a la distribució i nou màxim altitudinal pel dragó comú Tarentola mauritanica (Linnaeus, 1758) a Catalunya RESUM Es dóna a conèixer la presència de Tarentola mauritanica a tres noves quadrícules UTM 10x10 (31T DG22; 31T DG09 i 31T CG99) a les comarques catalanes del Moianès i la Cerdanya, on fins ara no estaven referenciades...

In this note, a new localization for the Pelphylax Kl. grafi species is referenced. The individuals was captured for first time in 2009 and recently recaptured in 2017 (after 7 years and 215 days). The individual was identified by its unique pattern of coloration. The estimated age (according to skeletochronology) was 11, that is the highest longev...

RESUM Es dóna a conèixer la presència de la sargantana roquera Podarcis muralis a una nova quadrícula UTM 10x10 (DG61) al terme municipal de Sant Celoni (Vallès Oriental, Catalunya), localitzada a baixa alçada (77 msnm). A la conca mitja i baixa de la Tordera, la dispersió i aïllament de les anteriors dades cone-gudes (totes d'una certa antiguitat...
