    Digital herbarium archives as a spatially extensive, taxonomically discriminate phenological record; a comparison to MODIS satellite imagery

    This study demonstrates that phenological information included in digital herbarium archives can produce annual phenological estimates correlated to satellite-derived green wave phenology at a regional scale (...

    Long-term herbarium records reveal temperature-dependent changes in flowering phenology in the southeastern USA

    In recent years, a growing body of evidence has emerged indicating that the relationship between flowering phenology and climate may differ throughout various portions of the growing season. These differences ...

    Timing the bloom season: a novel approach to evaluating reproductive phenology across distinct regional flora

    Just as the timing of the vegetative growing season affects a host of ecological processes, the seasonality of floral availability impacts ecological processes from nectar availability and allergen production ...

    Biogeochemical Cycling of Carbon and Nitrogen in Chaparral Dominated Ecosystems

    The controls and trajectories of biogeochemical dynamics in chaparral dominated ecosystems are highly diverse. This breadth of diversity in chaparral biogeochemical dynamics is caused by a combination of diver...

    Plasticity and not adaptation is the primary source of temperature-mediated variation in flowering phenology in North America

    Phenology varies widely over space and time because of its sensitivity to climate. However, whether phenological variation is primarily generated by rapid organismal responses (plasticity) or local adaptation ...
