description	Background and aims: Invasive plants succeeding at high-elevation ecosystems threaten biodiversity and ecosystem services conservation in mountain protected areas. In this study we assessed whether an exotic woody species, Cotoneaster franchetii Bois, responds to mountain environmental heterogeneity in a similar way to the dominant coexisting native woody species, Polylepis australis Bitter, or if it instead occupies a greater variety of habitats aided by the wide environmental tolerance expected for mountain invaders. M&M: We recorded C.franchetii and P. australis occurrence and cover in 120 square plots between 1200 and 2200 masl, inside and surrounding “Quebrada del Condorito” National Park and “Pampa de Achala” natural reserve (Córdoba, Argentina). We compared both species’ distribution and its relationship with vegetation and topograpy. Results: Each species dominated at different elevations. However, at local scale,both species were more frequent in plots placed at valleys and south-facing steep slopes, with less cover of tussock grassland and more rock cover. Contrary to the native species, C. franchetii cover was unaffected by vegetation and topographic characteristics. Conclusions: High occurrence and no restrictions for increasing cover once established suggest a high spread potential of C. franchetii in these mountains. Polylepis australis is seemingly at risk since both species share habitat preferences. Wide environmental tolerance would not only trigger upward expansion of invasive species in mountains but also towards natural vegetation.

Introducción y objetivos: El aumento de plantas invasoras en ecosistemas de altura amenaza la conservación de la biodiversidad y de los servicios ecosistémicos en áreas protegidas de montaña. En este trabajo evaluamos si una leñosa exótica, Cotoneaster franchetii Bois, responde a la heterogeneidad ambiental de manera similar a la leñosa nativa dominante, Polylepis australis Bitter, o si puede ocupar una mayor variedad de hábitats dado el carácter generalista que se espera de ella. M&M: Registramos la ocurrencia y cobertura de ambas especies en 120 parcelas entre los 1200 y los 2200 msnm, dentro y en inmediaciones del Parque Nacional Quebrada del Condorito y la Reserva Hídrica Pampa de Achala (Córdoba, Argentina). Comparamos su distribución en relación con la vegetación y la topografía. Resultados: Cada especie dominó en altitudes diferentes pero, a escala local, ambas fueron más frecuentes en valles y laderas sur, con menor cobertura de pajonal y mayor cobertura rocosa y pendiente. Al contrario que la nativa, la cobertura de C. franchetii no se vio afectada por las características topográficas ni de la vegetación circundante. Conclusiones: La elevada ocurrencia de C. franchetii y la ausencia de restricciones para aumentar su cobertura una vez establecida sugieren un elevado potencial invasor. Su expansión representa un riesgo directo para P. australis por preferir hábitats similares. Al igual que en la expansión altitudinal, una elevada tolerancia ambiental promovería la invasión por leñosas hacia la vegetación natural en montañas Sociedad Argentina de Botánica 2023-03-22 info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion application/pdf text/html https://revistas.unc.edu.ar/index.php/BSAB/article/view/38464 Boletín de la Sociedad Argentina de Botánica (Journal of the Argentine Botanical Society; Vol. 58 No. 1 (2023): March Boletín de la Sociedad Argentina de Botánica; Vol. 58 Núm. 1 (2023): Marzo Boletín de la Sociedad Argentina de Botánica; v. 58 n. 1 (2023): Marzo 1851-2372 0373-580X 10.31055/1851.2372.v58.n1 spa https://revistas.unc.edu.ar/index.php/BSAB/article/view/38464/40863 https://revistas.unc.edu.ar/index.php/BSAB/article/view/38464/40864 Derechos de autor 2023 María Cecilia Ferrero, Diego E.
