Effects of landscape context on herbivory and parasitism at different spatial scales [PDF]

open access: yes, 2003

Reproductive success through high pollinator visitation rates despite self incompatibility in an endangered wallflower [PDF]

open access: yes, 2016
PREMISE OF THE STUDY: Self incompatibility (SI) in rare plants presents a unique challenge—SI protects plants from inbreeding depression, but requires a sufficient number of mates and xenogamous pollination. Does SI persist in an endangered polyploid? Is
