The genetics and evolution of fluctuating asymmetry
Article Abstract:
A study on the role that genetics play in producing variation in the subtle differences between right and left sides of bilateral characters known as fluctuating asymmetry (FA) is presented. The heritability of FA is typically very low or zero, but epistasis can generate additive genetic variation for FA that might allow it to evolve especially in populations subjected to bottlenecks, hybridizations, or periods of rapid environmental changes caused by various stresses.

Evolutionary history of Poales
Article Abstract:
A study of the factors that have influenced evolution in Poales is presented. By the Paleogene the lineage has diversified into swamps, the forest understory, epiphytic habitats, and nutrient poor heathlands and the Neogene saw major diversifications of the grasses and possibly the sedges into fire-adapted vegetation in seasonal climates and low atmospheric CO(sub 2).

Evolutionary causes and consequences of immunopathology
Article Abstract:
A study of the evolutionary causes and effects of immunopathology is presented. The evolution of strategies for parasite virulence and host resistance might be shaped by immunity and future work might reveal whether immunopathology constrains the evolution of resistance in all host taxa.
