“…In recent years, the eradication of a population in Yosemite National Park, United States of America, was also reported with the use of seine net for tadpoles, and hand catching and shooting for postmetamorphs (Kamoroff et al, 2020). In addition, in Belgium, fyke nets have been used successfully to control bullfrogs (Louette et al, 2013;Descamps and De Vocht, 2023). These efforts can be complemented with a series of promising new techniques that can amplify the results (e.g.…”

Biological invasions are a major cause of biodiversity and ecosystem services loss. However, information on distribution and impacts is limited for many alien species, restricting the development of local management measures. The aim of this study is: to identify the current situation of the American bullfrog (Lithobates catesbeianus) invasion focus in San Carlos (Maldonado, Uruguay); to evaluate its impacts on native anurans; and to provide management tools. Between 2017 and 2019, 75 permanent ponds were sampled, finding an expanding bullfrog population (occupying 32 ponds, in 16.5 km2). Results show that native anuran richness was lower in the invaded ponds. Observed impacts were greater for the aquatic frog Pseudis minuta, probably due to greater encounter rates with the invader. The abundance of tadpoles was also lower in the invaded ponds. The local pond network was explored using graph theory, evaluating its topological role and centrality. In this network, a list of priority ponds was generated to prevent local bullfrog expansion. Given the relatively small size of this population, eradication seems feasible. Focusing on the key nodes could prevent further expansion, by using spatial prioritization to organize the recommended management of the pond network.

Las especies exóticas invasoras representan una amenaza significativa para la biodiversidad mundial. En la península de Baja California (México) estos organismos han proliferado y las medidas tomadas han sido insuficientes para mitigar su expansión y reducir su impacto ambiental. En este estudio, se desarrolló un índice de erradicación específico para la rana toro (Lithobates catesbeianus; Shaw, 1802), clasificada como una de las 100 especies invasoras más dañinas a nivel global. Este índice, basado en el método de Jerarquías Analíticas de Saaty, utiliza 11 variables ambientales y sociales, cuantitativas y cualitativas, para identificar los sitios con mayor potencial de erradicación en la región mediterránea de Baja California. La metodología ofrece el primer enfoque sistemático para evaluar y priorizar las localidades invadidas por la rana toro, identificando áreas con posibilidades óptimas para su erradicación exitosa. Entre las variables más influyentes se destacan la proximidad a cuerpos de agua con presencia de rana toro (30 %), seguida del número de refugios y áreas de migración en un radio de 11 km (22 %), y el tamaño del cuerpo de agua (14 %). Tras evaluar 32 localidades, se han identificado sitios piloto como Rancho Madrigal para iniciar el proceso de erradicación de L. catesbeianus, junto con La Misión y El Rosario, identificados como áreas con alto potencial para su erradicación.
