Clonal dynamics and evolution of dormancy in the leafy hepatic Lophozia silvicola

Article Abstract:

Studies on Lophozia silvicola show that a decrease in the germinating gemmae will result from selection pressure on season-specific dormancy population fractions. Data were obtained from a three-year research period on L. silvicola populations in southern Finland.

Flammability and serotiny as strategies: correlated evolution in pines

Article Abstract:

Research on 38 species of the Pinus genus shows a pronounced evolutionary shift along fire-surviving and fire-embracing life histories. It is posited that fire-embracing may be an evolutionarily selected strategy for the prompting serotinous seed-release.

Optimality modeling and fitness trade-offs: when should plants become pollinator specialists?

Article Abstract:

The author emphasizes the importance of plant pollinator-mediated fitness trade-offs, rather than pollinator effectiveness, in adaptive and selection value of floral traits.
