متن کاملCarbon export and cycling by the Yukon , Tanana , and Porcupine rivers , Alaska , 2001 – 2005
[1] Loads and yields of dissolved and particulate organic and inorganic carbon (DOC, POC, DIC, PIC) were measured and modeled at three locations on the Yukon River (YR) and on the Tanana and Porcupine rivers (TR, PR) in Alaska during 2001–2005. Total YR carbon export averaged 7.8 Tg C yr , 30% as OC and 70% as IC. Total C yields (0.39–1.03 mol C m 2 yr ) were proportional to water yields (139–3...
متن کاملGenetic Characterization of Common Eiders Breeding in the Yukon-kuskokwim Delta, Alaska
We assessed population genetic subdivision among four colonies of Common Eiders (Somateria mollissima v-nigrum) breeding in the Yukon-Kuskokwim Delta (YKD), Alaska, using microsatellite genotypes and DNA sequences with differing modes of inheritance. Significant, albeit low, levels of genetic differentiation were observed between mainland populations and Kigigak Island for nuclear intron lamin ...
