Distribución de una leñosa exótica invasora en un sistema de montaña ¿ocupan Cotoneaster franchetii y la leñosa nativa Polylepis australis (Rosaceae) hábitats similares?

Abstract: 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 ocurr… Show more

“…in the eastern slope of the Sierras Grandes of Córdoba, Argentina. While this mountain system extends up to ~2800 m a.s.l., the studied range corresponds to the actual distribution range of C. franchetii (Ferrero et al, 2023; Giorgis et al, 2021). The vegetation corresponds to the Mountain Chaco District with three elevational belts (Cabrera, 1976): (1) The lower portion of Chaco mountain woodlands, which spans from 400 to 1300 m a.s.l.…”

“…(Zheng‐Yi et al, 2003). In the mountains of this study, C. franchetii invades a broad variety of habitats and topographies, being most frequently found in valleys and on south‐facing slopes, particularly in areas where the vegetation is open, characterized by low tussock cover, and/or a high abundance of rocky outcrops (Ferrero et al, 2023). Fruits are produced in large numbers per individual, are slightly elongated (6–9 mm in diameter), bright red when ripe, and each contains 2–3 internal seeds (Díaz Vélez et al, 2018; Sérsic et al, 2015).…”
