El Catálogo Colectivo reúne los registros del material que posee cada una de las
bibliotecas de la Universidad Nacional de Córdoba, pudiendo encontrarse colecciones
especializadas y actualizadas en todas las áreas del conocimiento; lo que permite una
amplia visibilidad y garantiza el acceso al patrimonio documental de la Universidad.
Se encuentra disponible para toda la comunidad académica: estudiantes, docentes,
egresados e investigadores.
Si formas parte de la comunidad de la UNC también podés solicitar préstamos de material,
a cualquier biblioteca universitaria, utilizando el servicio de préstamo interbibliotecario,
independientemente de la facultad a la que pertenezcas, la carrera que curses o la cátedra
que dictes.

To evaluate the natural revegetation as a restoration strategy, the dynamics, structure and regeneration of the plant communities should be understood. The objective of this work is to analyze the changes in the forest structure of the plant communities in the center of Córdoba, its dynamics, and regeneration along a time lapse of six years, evaluating the effect of cattle and precipitations. In 16 sites located in the Natural Reserve of the Defensa La Calera the woody species and their regeneration were surveyed (2013, 2016, 2019) in four different plant communities. Cattle was excluded from seven sites and it was present in low loads in the other nine (~12 ha EV-1). The local standardized precipitation indexes were calculated. The cattle exclusion did not lead to higher regeneration. In the communities a positive evolution towards maturity was observed, with the most dynamic communities being those of Sebastiania. In the deforested areas, Geoffroea decorticans and Schinus fasciculatus present an important survival rate and growth speed. In Vachellia and Schinopsis communities the regeneration follows the precipitation dynamics. According to the results, passive revegetation is an important recovery strategy in natural and semi-natural environments of the center of Córdoba.
