Effects of fire on a forest-grassland ecotone in De La Plata River, Argentina
This study adds information on the dynamics of pioneer forest trees in the face of frequent fire. In particular, effects of fire on the regeneration dynamics and ecological attributes of a Tessaria integrifolia forest and a Cortaderia selloana grassland, located in the Costanera Sur Ecological Reser...
