Relationship between two pathogens in an amphibian community that experienced m...
Thumsová, Barbora; Alarcos, Gonzalo; Ayres, Cesar; Rosa, Gonçalo M.; Bosch, JaimeBecause host species tend to harbor multiple parasitic species, coinfection in a host is com-mon. The chytrid fungusBatrachochytrium dendrobatidis(Bd) and the viruses in the genusRanavirus(Rv) are responsible for the decline of amphibians worldwide. Despite widegeographical co-occurrence and the serious conservation problem that coinfection withthese pathogens could represent, little is known about their possib...
Climate warming triggers the emergence of native viruses in Iberian amphibians
Thumsová, Barbora; Price, Stephen J.; González-Cascón, Victoria; Vörös, Judit; Martínez-Silvestre, Albert; Rosa, Gonçalo M.; Machordom, AnnieThe number of epizootics in amphibian populations caused by viruses of the genus Ranavirus is increasing worldwide. Yet, causes for pathogen emergence are poorly understood. Here, we confirmed that the Common midwife toad virus (CMTV) and Frog virus 3 (FV3) are responsible for mass mortalities in Iberia since the late 1980s. Our results illustrate the Iberian Peninsula as a diversity hotspot for the highly viru...
New insights on patterns of genetic admixture and phylogeographic history in Ib...
Lucati, Federica; Miró, Alexandre; Bosch, Jaime; Caner, Jenny; Jowers, Michael Joseph; Rivera, Xavier; Donaire-Barroso, David; Sampaio e rebelo, RuiMultiple Quaternary glacial refugia in the Iberian Peninsula, commonly known as “refugia within refugia”, allowed diverging populations to come into contact and admix, potentially boosting substantial mito-nuclear discordances. In this study, we employ a comprehensive set of mitochondrial and nuclear markers to shed light onto the drivers of geographical differentiation in Iberian high mountain populations of t...
Impacts of detritivore diversity loss on instream decomposition are greatest in...
Boyero, Luz; López-Rojo, Naiara; Tonin, Alan M.; Pérez, Javier; Correa-Araneda, Francisco; Pearson, Richard G.; Bosch, Jaime; Albariño, Ricardo J.The relationship between detritivore diversity and decomposition can provide information on how biogeochemical cycles are affected by ongoing rates of extinction, but such evidence has come mostly from local studies and microcosm experiments. We conducted a globally distributed experiment (38 streams across 23 countries in 6 continents) using standardised methods to test the hypothesis that detritivore diversit...
Latitude dictates plant diversity effects on instream decomposition
Boyero, Luz; Pérez, Javier; López-Rojo, Naiara; Tonin, Alan M.; Correa-Araneda, Francisco; Pearson, Richard G.; Bosch, Jaime; Albariño, Ricardo J.Running waters contribute substantially to global carbon fluxes through decomposition of terrestrial plant litter by aquatic microorganisms and detritivores. Diversity of this litter may influence instream decomposition globally in ways that are not yet understood. We investigated latitudinal differences in decomposition of litter mixtures of low and high functional diversity in 40 streams on 6 continents and s...
Are oral deformities in tadpoles accurate indicators of anuran chytridiomycosis?

Development and worldwide use of non-lethal, and minimal population-level impac...
Fisher, Matthew C.; Ghosh, Pria; Shelton, Jennifer M. G.; Bates, Kieran; Brookes, Lola; Wierzbicki, Claudia; Rosa, Gonçalo M.; Farrer, Rhys A.Parasitic chytrid fungi have emerged as a significant threat to amphibian species worldwide, necessitating the development of techniques to isolate these pathogens into culture for research purposes. However, early methods of isolating chytrids from their hosts relied on killing amphibians. We modified a pre-existing protocol for isolating chytrids from infected animals to use toe clips and biopsies from toe we...
Distribution, abundance and density of the wild boar on the Iberian Peninsula, ...
Bosch, Jaime; Peris, Salvador; Fonseca, Carlos; Martinez, Marta; Torre, Ana De la; Iglesias, Irene; Muñoz, Maria J.Wild boar population size in the Iberian Peninsula was estimated using hunting bag statistics from Spain and Portugal. Density was estimated assigning the wild boar population size to the “potential resources” or suitable habitats categorized by their importance to provide food and/or shelter to wild boars. Land uses were selected from CORINE, the EU database for land cover, using scientific literature and stat...
