Ranunculus acris (Ranunculaceae), a potentially invasive species: confirmation of its presence in Argentina and naturalization in Tierra del Fuego.
Background and aims: The European Ranunculus acris is an invasive species in the world, and has been reported for the Northeast and South of Argentina. However, its presence is not conclusive, and it is not mentioned in recent floras of the country. The objective of the work is to confirm the presen...

Background and aims: The European Ranunculus acris is an invasive species in the world, and has been reported for the Northeast and South of Argentina. However, its presence is not conclusive, and it is not mentioned in recent floras of the country. The objective of the work is to confirm the presence of the species R. acris in Argentina and its naturalization in Tierra del Fuego. In addition, it is proposed to analyze its morphology and its potential invasive behavior in the new environment.
M&M: Herbarium specimens of R. acris and other species of the genus Ranunculus, and populations in its natural environment, in anthropized areas of the city of Ushuaia and surrounding areas, Tierra del Fuego, were studied. The morphology was comparatively analyzed and the taxonomic identity was established based on the type material, and previous descriptions and keys. To study the invasive potential of R. acris, an invasion risk matrix and specialized literature were used.
Results: The presence of R. acris is confirmed for Argentina, expanding its range of distribution in the extreme south of the country, and it is recognized as naturalized in Tierra del Fuego. Based on the morphological analysis, glabrous receptacle, erect habit and deeply lobed leaves were identified as characters of taxonomic value. According to the analysis of the invasion risk matrix, it is established that R. acris has a high invasive potential.
Conclusion: Ranunculus species for Tierra del Fuego increase by nine, two of them being exotic. The possibility of eliminating naturalized populations of R. acris in the extreme South of Argentina should be evaluated due to its high invasive potential. |

Introducción y objetivos: la especie europea Ranunculus acris es invasora en el mundo, y ha sido citada para el noreste y sur de Argentina. Sin embargo, su presencia no es concluyente, no citándose en floras recientes del país. El objetivo del trabajo es confirmar la presencia de la especie R. acris en Argentina y su naturalización en Tierra del Fuego. Además, se propone analizar su morfología y su potencial comportamiento invasor en el nuevo ambiente. M&M: Se estudiaron especímenes herborizados de R. acris y otras especies del género Ranunculus, y poblaciones en su ambiente natural, en zonas antropizadas de la ciudad de Ushuaia y alrededores, Tierra del Fuego. Se analizó de forma comparada la morfología y estableció la identidad taxonómica sobre la base del material tipo, y descripciones y claves previas. Para estudiar el potencial invasor de R. acris se utilizó una matriz de riesgo de invasión y bibliografía especializada. Resultados: Se confirma la presencia de R. acris para Argentina, ampliando su rango de distribución en el extremo sur del país, y se reconoce como naturalizada en Tierra del Fuego. Sobre la base del análisis morfológico se identificó el receptáculo glabro, el hábito erecto y las hojas profundamente lobadas como caracteres de valor taxonómico. Según el análisis de la matriz de riesgo de invasión, se establece que R. acris posee un alto potencial invasor. Conclusión: Las especies de Ranunculus para Tierra del Fuego se incrementan en nueve, siendo dos de ellas exóticas. Debería evaluarse la posibilidad de eliminar las poblaciones naturalizadas de R. acris en el extremo sur argentino debido a su alto potencial invasor.
