Flower and fruit production and insect pollination of the endangered Chilean tree, Gomortega keule in native forest, exotic pine plantation and agricultural environments

This study was undertaken to discover whether patterns of flower and fruit production for Gomortega keule, an endangered Chilean tree, differ between exotic pine plantation, agricultural and native forest environments. A pilot study was also undertaken to identify the primary pollinators of G. keule...
