Coexistence and competitive exclusion of Banksia hookeriana in the presence of congeneric seedlings along a topographic gradient
Oikos, Vol.56(1), pp.39-42
1989
Abstract
Banksia hookeriana is restricted to the midrange of a gradient from a sand dune swale to a sand-over-limestone ridge in Western Australia. As a monoculture, B. hookeriana seedlings established equally at three sites along the gradient, but when mixed with seedlings of 4 other Banksia species abundant along the gradient, B. hookeriana was eliminated from all sites except where it occurs naturally. Drought stress, as measured by leaf xylem tension and stomatal conductance, increased with greater density of seedlings, with increase in elevation, and over summer. The negative interaction between certain habitats and interspecific competitive pressure in association with the 1st summer drought may account for the restricted distribution of this species.
