Evolutionary drivers of mast-seeding in a long-lived desert shrub.
PREMISE OF THE STUDY The evolutionary drivers and proximal regulators of mast-seeding are well understood for species of mesic environments, but how these regulators interact with high spatial and interannual variability in growing-season precipitation for a masting species in a desert environment has never been examined. METHOD We followed flowering and seed production in 16 populations of t...
متن کاملA mast-seeding desert shrub regulates population dynamics and behavior of its heteromyid dispersers.
Granivorous rodent populations in deserts are primarily regulated through precipitation-driven resource pulses rather than pulses associated with mast-seeding, a pattern more common in mesic habitats. We studied heteromyid responses to mast-seeding in the desert shrub blackbrush (Coleogyne ramosissima), a regionally dominant species in the Mojave-Great Basin Desert transition zone. In a 5-year ...
متن کاملRevegetation Priorities
Revegetation is a needed means of mitigating man-made and natural disturbance. Our current ability to address environmental insults contrasts sharply with that existing when John Muir fi rst sowed the roots of environmental awareness or Aldo Leopold and Hugh H. Bennett inspired a land ethic and a sense of stewardship. We now have considerable revegetation science and experience and—equally impo...
متن کاملFurther Dihydrochalcones from Crotolaria ramosissima
Crotolaria ramosissima is a weed plant belonging to the family Leguminoseae. It is a much branched sticky woody herb. The flowers are yellow tinged with purple. It is distributed in some places of Tamilnadu and coastal areas of Andrha Pradesh. The plant contains waxes, and, when flowering, a yellow exudate appears in the inflorescences. Recently, we published the corrected structure of crotaram...
متن کاملDisturbance automated reference toolset (DART): Assessing patterns in ecological recovery from energy development on the Colorado Plateau.
A new disturbance automated reference toolset (DART) was developed to monitor human land surface impacts using soil-type and ecological context. DART identifies reference areas with similar soils, topography, and geology; and compares the disturbance condition to the reference area condition using a quantile-based approach based on a satellite vegetation index. DART was able to represent 26-55%...
