Population differentiation along a flood frequency gradient: Physiological adaptations to flooding in Nyssa sylvatica Population differentiation along a flood frequency gradient: Physiological adaptations to flooding in Nyssa sylvatica
Throughout the southeastern United States the hardwood Nyssa sylvatica (sensu lato) is distributed along a soil moisture gradient from upland sites, which are never flooded, to floodplains, which are periodically flooded and drained to permanently flooded swamps. Population differentiation with respect to flood tolerance and related physiological attributes was investigated using 1—year...

Quantitative variation and the ecological role of vulpinic acid and atranorin in thallus of Letharia vulpina Quantitative variation and the ecological role of vulpinic acid and atranorin in thallus of Letharia vulpina
High pressure liquid chromatography was used to determine concentrations of vulpinic acid and atranorin in the thaullus of Letharia vulpina. Vulpinic acid concentration is lowest in the old basal branches of the thallus and increases toward the young branch tips, whereas the reverse is true for atranorin. The suggested role of vulpinic acid as an anti-herbivore defense compound is...
