The importance of periodic droughts for maintaining diversity in the freshwater environment [PDF]
, 1996 Whereas some species may rely on periodic drought conditions for part of their life histories, or have life strategies suited to exploiting the habitat or changed environmental conditions that are created by drought, for other organisms it is a time of ...

Color polymorphism in Anemone coronaria: Correlations with soil, climate, and flowering phenology
American Journal of Botany, EarlyView.Abstract Premise Flower color polymorphism (FCP) is thought to be driven by multiple selection agents. Although widely associated with visual attraction of multiple pollinators, FCP is also often correlated with abiotic factors. We explored the links between abiotic conditions, flowering phenology, and FCP in the winter‐flowering geophyte Anemone ...

American Journal of Botany, EarlyView.Abstract Premise Evolutionary theory predicts polymorphism should be rare; however, intraspecific variation in floral color is common and can be attributed to genetic drift, plasticity, or variable selection. Examining floral color polymorphism both within contact zones and across a species' range can reveal the mechanisms maintaining this variation ...

Developing a Customized Composite Drought Index for Pakistan [PDF]
Pakistan experiences frequent and intense agricultural drought, varying spatially and temporally. Prolonged dry conditions often result in failed crop production.

American Journal of Botany, EarlyView.Abstract Premise Floral pigments primarily serve to attract pollinators through color display and also contribute to protection against environmental stress. Although pigment composition can be plastically altered under stress, its impact on pollinator color perception remains poorly understood.

Temperature and the evolution of flower color: A review
American Journal of Botany, EarlyView.Abstract Flower colors brighten our natural world. How and why have they evolved? How might ongoing global warming alter their evolutionary trajectories? In this review, I examine the influence of ambient temperature on the evolution of flower color.
