Forest fragmentation in the Argentine Chaco: recruitment and population patterns of dominant tree species

The forest in the Central Argentine Chaco has been dramatically fragmented and persists only as isolated patches in an agricultural matrix. In this study, we evaluated the effects of fragmentation on total density, recruitment, and size-class structure of its dominant tree species, a key issue, alth...
