Trace Element Concentrations in Feathers of Migratory Birds from the Southern Caspian Sea Region, 2013
This dataset presents concentrations of eight trace elements—arsenic (As), cadmium (Cd), chromium (Cr), iron (Fe), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn)—measured in secondary flight feathers of waterbird species wintering along the southern Caspian Sea coast of Iran. Samples were collected in February 2013 from multiple species representing diverse feeding guilds and avian families. The data support ecological assessments of contaminant exposure in migratory birds and provide insight into trophic-level accumulation patterns. Elemental analysis was performed using standardized laboratory protocols, and values are reported in micrograms per gram dry weight (µg/g dw). This dataset contributes to regional biomonitoring efforts and can be used for comparative studies in avian ecotoxicology and environmental risk assessment.
Near-total element concentration for mineral soils (0-10 cm) collected in 2012 at Murphy Dome study site
This file contains near-total element digestion for mineral soils (0-10 cm) for black spruce and Alaska paper birch forest in the Murphy Dome fire scar near Fairbanks, AK. All information was collected in summer 2012 and subsequently processed and analyzed in the laboratory.
Near-total Element Concentrations for deep soils (0-100 cm) collected from Murphy Dome study site in 2013
This file contains near-total element digestion for deeper soils (0-100cm) for black spruce and Alaska paper birch forest in the Murphy Dome fire scar near Fairbanks, AK. All information was collected in summer 2013 and subsequently processed and analyzed in the laboratory.
Effect of insecticide treatment on Salix interior stem tannin activity and elemental composition.
This dataset contains information on stem chemistry of Salix interior within experimental plots on the Tanana River. There are 6 permanent plots, each of which contains two fenced subplots and two unfenced subplots. Subplots are sprayed with either insecticide (insect-treated subplots) or water (controls) annually. This particular dataset contains chemistry data for leaves collected from insecticide-treated and control subplots only within fenced subplots. The intent was to measure the effect of insect herbivory on chemistry in the absence of browsing.
Carbon in Permafrost Experimental Heating Research (CIPEHR) project: Foliar mineral element concentrations, stocks, and annual litterfall fluxes in July 2009 and 2017
In this study, we are asking the question: how permafrost degradation may influence foliar mineral element cycling with changing subarctic tundra vegeatation? We are answering this question by using a combination of field measurements (aboveground biomass, foliar biomass, foliar net primary productivity (NPP)) and laboratory measurements (mineral element foliar concentration: Al, Ca, Fe, K, Mn, P, S, Si, and Zn) to evaluate the mineral element foliar stocks and the mineral element foliar fluxes upon annual litterfall. We covered 5 vascular plant species from an established tundra field site near Healy, Alaska in the foothills of the Alaska Range. Field measurements center on at a warming experiment located in an upland tundra field site near Healy, Alaska in the foothills of the Alaska Range. Elemental analyses of plant species typical from the moist acidic tundra (in 2009 and 2017), combined with relative aboveground biomass and NPP measurements, brought key information on the influence of permafrost degradation and the vegetation composition on the litter elemental composition, and thereby the plant nutrient cycling across the subarctic tundra.
