A New Twist on an Old Story: Pollination and Seed Predation in Jadera haematoloma | The American Naturalist: Vol 206, No 2 Abstract Pollinating seed predators are partners in a specialized plant-insect mutualism where insects pollinate the flower ovules of the seeds that they later consume. Such relationships have proven ...
