BUSCADOR RECOLECTA

Climatic data was obtained from Worldclim Version 1&2, soil data from the European Soil Database, and Normalized Difference Vegetation Indices (NDVI) from satellite images through the Modis Vegetation index MOD13Q1. For skeletochronology, telomere, and microsatellite analyses we collected a total of 180 Epidalea calamita adult males across all populations. We then clipped the fourth toe of the right hindlimb that we then used for cross sectioning and DNA extractions. Stable isotope data were obtained from E. calamita egg clutches, which allows direct assessment of the diet of the female without harming any adults. We collected small sections of egg clutches that were kept under identical conditions in the lab until hatching and then determined the carbon and nitrogen levels of these samples. Standard metabolic rate was assessed in a terrestrial respirometer overnight, for which we brought in mature males from the field at night. Advertisement calls were recorded using a shotgun microphone and subsequently analysed using the software Raven Pro v.1.4. For female behavioural assays we brought in receptive females at night to the lab and played back recorded calls. All individuals were released at dawn and no individual was harmed., This dataset consists of a single excel file split into distinct sheets for different types of data: climate, population genetics, stable isotopes, standard metabolic rate, skeletochronology, telomere length, male advertisement calls, and female preference tests. The climatic data is split into sheets for NDVI, Worldclim Bio19, and edaphology. The population genetics data is split into sheets for basic statistics, genetic differentiation indicators, isolation by distance, and effective population size., Plan Nacional (grant CGL2014-59206-P), No

Invasive species cause major ecosystem impacts. To prioritise management, it is first necessary to recognise which invaders have the highest impact, as outlined by the Convention on Biological Diversity’s Strategic Plan 2020. We show for the first time that chemical compounds previously shown to be used in ant defence against other ant species can also be used to prey upon vertebrates of relatively greater size. We estimate the number of amphibian species whose ranges overlap with those of the Argentine ant across the globe and examine the likely global threat to terrestrial amphibians, an already endangered taxonomic group., Peer reviewed
