- Distribution of alien tetrapods in the Iberian PeninsulaPublication . Ascensão, Fernando; D'Amico, Marcello; Martins, Ricardo C.; Sampaio e rebelo, Rui; Barbosa, A. Márcia; Bencatel, Joana; Barrientos, Rafael; Abellán, Pedro; Tella, José L.; Cardador, Laura; Anadón, José D.; Carrete, Martina; Murgui, Enrique; Fernandes, Pedro; Santos, Sara M.; Mira, António; da Luz Mathias, Maria; Tiago, Patrícia; Casabella, Eduardo; Reino, Luís; Paulo, Octávio S.; Pereira, Henrique M.; Capinha, CésarWe present a dataset that assembles occurrence records of alien tetrapods (amphibians, reptiles, birds and mammals) in the Iberian Peninsula, a coherent biogeographically unit where introductions of alien species have occurred for millennia. These data have important potential applications for ecological research and management, including the assessment of invasion risks, formulation of preventive and management plans, and research at the biological community level on alien species. This dataset summarizes inventories and data sources on the taxonomy and distribution of alien tetrapods in the Iberia Peninsula, comprising known locations from published literature, expert knowledge and citizen science platforms. An expert-based assessment process allowed the identification of unreliable records (misclassification or natural dispersion from native range), and the classification of species according to their status of reproduction in the wild. Distributional data was harmonized into a common area unit, the 10 × 10 km Universal Transverse Mercator (UTM) system (n = 6,152 cells). The year of observation and/or year of publication were also assigned to the records. In total, we assembled 35,940 unique distribution records (UTM × species × Year) for 253 species (6 amphibians, 16 reptiles, 218 birds and 13 mammals), spanning between 1912 and 2020. The species with highest number of distribution records were the Mediterranean painted frog Discoglossus pictus (n = 59 UTM), the pond slider Trachemys scripta (n = 471), the common waxbill Estrilda astrild (n = 1,275) and the house mouse Mus musculus (n = 4,043), for amphibians, reptiles, birds and mammals, respectively. Most alien species recorded are native to Africa (33%), followed by South America (21%), Asia (19%), North America (12%) and Oceania (10%). Thirty-six species are classified by IUCN as threatened in their native range, namely 2 Critically Endangered (CR), 6 Endangered (EN), 8 Vulnerable (VU), and 20 species Near Threatened (NT). Species maps are provided in DataSet1, as well R code and GIS layers to update them as new records are obtained.

- Drivers of compositional dissimilarity for native and alien birds: the relative roles of human activity and environmental suitabilityPublication . Ascensão, Fernando; Latombe, Guillaume; Anadón, José D.; Abellán, Pedro; Cardador, Laura; Carrete, Martina; Tella, José L.; Capinha, CésarWe assessed the relative importance of human activity and environmental suitability as drivers of compositional dissimilarity of alien birds for 65 of the most populous cities of the Iberian Peninsula. We examined how these drivers relate to Zeta diversity (ζ) for alien Passeriformes and Psittaciformes. We performed the analysis using multiple orders of ζ, which provides insight on the role played by rare and common species in determining levels of dissimilarity. We also ran the analyses using the community of native Passeriformes as a phylogenetically close contrasting control. Our results showed that the proportion of urban area, a variable related to colonization and propagule pressure, had a strong influence on Psittaciformes but not on alien Passeriformes. This latter group showed to be primarily influenced by environmental factors, similarly to what was found for native Passeriformes. On other hand, human connectivity, as measured by distance through roads and railways seemed to play a significant role in shaping the compositional dissimilarity of alien Passeriformes, but not Psittaciformes. Regardless of the group analysed, the relative importance of the explanatory variables was similar for both rare and common species. Our findings highlight differences between the factors driving compositional dissimilarity for distinct groups of birds. While the emerging biogeography of Psittaciformes is mainly a reflection of distinctiveness in urban areas, alien Passeriformes are more strongly affected by the natural environment and thus their biogeography may increasingly resemble the one of their native counterparts.
- Regional bans on wild-bird trade modify invasion risks at a global scalePublication . Cardador, Laura; Lattuada, Matteo; Strubbe, Diederik; Tella, José L.; Reino, Luís; Figueira, Rui; Carrete, MartinaWildlife trade is currently the most important and increasing source of vertebrate invasive species. However, exhaustive analyses of potential side effects of trade regulations on this pathway of introduction are lacking. We addressed this by combining environmental niche models and global trade data on parrots (Psittaciformes), one of the most widely traded and worldwide invasive taxa. We used the wild bird trade bans of United States (1992) and Europe (2005) as case-studies. Results showed that regional bans can generate geographic redirections in trade, with important consequences on worldwide invasion risk. While the amount of parrots traded internationally remained largely constant, changes in trade destination occurred. Consequently, the world surface predicted at risk of parrot invasions increased with successive bans. Of concern, a redirection of trade toward developing countries was observed. Attention should be paid on the mismatch between the global requirements of invasion management and the regional scales governing trade regulations
