Abstract: | In the light of putatively increasing liana abundances in present-day tropical forests and a persistent lack of understanding of liana abundance patterns and the responsible factors, we attempt to identify the key factors controlling liana abundance along an altitudinal transect in NE Ecuador. At four elevational levels (500, 1000, 1500, and 2000 m), each represented by 10 plots of 400 m2, the abundance and diameters of all lianas (dbh ≥ 1 cm) and trees (dbh ≥ 10 cm) were recorded in old-growth forest stands in the Sumaco Biosphere Reserve (SBR). Results were analysed with available data on soil chemical properties and canopy structure. |
