Effects of selective logging on dynamics and composition of woody seedlings in a tropical secondary forest

This study was conducted in a logging road in a 28 years old secondary forest in theAtlantic lowlands of Costa Rica. We gathered information from three different microhabitats:track road, edge road and an adjacent logged forest. The main objective was to study thedynamics and composition of woody se...
