alaskan wild berry resources and human health under the cloud of climate change.wild berries are integral dietary components for alaska native people and a rich source of polyphenolic metabolites that can ameliorate metabolic disorders such as obesity and diabetes. in this study, five species of wild alaskan berries (vaccinium ovalifolium , vaccinium uliginosum , rubus chamaemorus , rubus spectabilis , and empetrum nigrum) were screened for bioactivity through a community-participatory research method involving three geographically distinct tribal communities. compositional ...201020025229
distinguishing vaccinium species by chemical fingerprinting based on nmr spectra, validated with spectra collected in different laboratories.a method was developed to distinguish vaccinium species based on leaf extracts using nuclear magnetic resonance spectroscopy. reference spectra were measured on leaf extracts from several species, including lowbush blueberry (vaccinium angustifolium), oval leaf huckleberry (vaccinium ovalifolium), and cranberry (vaccinium macrocarpon). using principal component analysis, these leaf extracts were resolved in the scores plot. analysis of variance statistical tests demonstrated that the three group ...201424963620
nitrogen uptake in riparian plant communities across a sharp ecological boundary of salmon density.recent studies of anadromous salmon (oncorhynchus spp.) on the pacific coast of north america indicate an important and previously unrecognized role of salmonid nutrients to terrestrial biota. however, the extent of this uptake by primary producers and consumers and the influences on community structure remain poorly described. we examine here the contribution of salmon nutrients to multiple taxa of riparian vegetation (blechnum spicant, menziesii ferruginea, oplopanax horridus, rubus spectabili ...200312729462
