Plant Reproductive Ecology

 

There are few greater obstacles to sexual reproduction than the rarity or absence of one sex. Limited or no sexual reproduction can result in a species inability to adapt to a changing environment, leading to population declines and eventually species extinction. Yet among plants, specifically bryophytes, rarity or absence of one sex occur frequently. Although intriguing, the underlying causes of these patterns have infrequently been investigated. Our research program focuses on elucidating the factors resulting in an entire species or population being dominated by one sex. Such factors include variation in offspring sex ratios and sex differences in clonal expansion that are a function of differential growth, asexual reproduction, colonization and survival as well as sex differences in sex expression.
 

To study the causes and consequences of sex ratio variation we use an unusually broad array of techniques, including molecular-genetic analysis, physiological methods, greenhouse and growth chamber experiments, field experiments and monitoring, and mathematical modeling.   ---- D.
