Pollen removal, paternity, and the male function of flowers
Article Abstract:
Recent research findings have concluded that the selection of the floral attributes of hermaphroditic plants is often determined by their impact on male reproduction. There have been theoretical and empirical objections to this 'fleurs-du-male' hypothesis. However, it is argued that both are flawed in that the theoretical argument relied on an incorrect selection measure while the empirical argument involved an uncontrolled confounding variable.

Neotropical plant reproductive strategies and fossil pollen representation
Article Abstract:
High potential for outcrossing is the primary reproductive character that mediates the representation of taxa in palynological records. Pollen present in lake sediments is primarily monoecious or dioecious taxa pollinated by anemophily or by insects. Flower morphology is a significant factor in determining the pollinator and the release of pollen.
