each stream ecosystem may be impacted by land use and intensified human expansion. According to the fall macrobenthic results, nearly all sites saw an increase in %EPT, except for Massaponax 208 and Ni Route 1. Even though both Massaponax Creek and the Ni River are under EPA legal limits for phosphate and nitrate concentrations, the phosphate levels usually rose in summer on the Massaponax and ...

Glacial deposits in the southwestern Ahklun Mountains, southwestern Alaska, record two major glacier advances during the late Pleistocene. The Arolik Lake and Klak Creek glaciations took place during the early and late Wisconsin, respectively. During the Arolik Lake glaciation, outlet glaciers emanated from an ice cap centered over the central portion of the Ahklun Mountains and expanded beyond...

In order for the Bureau of Land Management (BLM) to comply with the Government Performance and Results Act (GPRA), and better meet the needs of the public; a visitor satisfaction survey was conducted at 23 BLM recreation sites in 11 states during fiscal year 2010 (FY10). The survey was developed to measure each site's performance related to BLM GPRA Goal 3.1 Provide for a quality recreation exp...

Redband trout (Oncorhynchus mykiss ssp.) in southeastern Oregon inhabit high-elevation streams that exhibit extreme variability in seasonal flow and diel water temperature. Given the strong influence and potential limitations exerted by temperature on fish physiology, we were interested in how acute temperature change and thermal history influenced the physiological capabilities and biochemical...

BACKGROUND Participation and performance trends have been investigated in ultramarathons and ultratriathlons but not in ultracycling. The aim of the present study was to investigate (1) participation and performance trends in ultraendurance cyclists, (2) changes in cycling speed over the years, and (3) the age of the fastest male and female ultraendurance cyclists. METHODS Participation and p...

The impact of anthropogenic activities on the accumulation heavy metals in water, sediment and fish both Ennore creek Vellar estuary were observed this study. Water sample collected from sampling stations was just only creek. Sediment samples subjected to a total digestion technique (HNO3 – HCl HF conc.) analysed using spectrophotometer. Four elements Cu, Cd, Zn Pb (trace elements) determined. ...

Sinking Creek (HUC 06010103046), in the Watauga watershed of northeast Tennessee, is impaired due to Escherichia coli. To assess how E. coli and other water quality parameters fluctuated during storm events, samples were collected with automated samplers eight storms at two locations: a feeder spring. Turbidity electrical conductivity data loggers deployed creek, dissolved oxygen (DO) was measu...

Dissolved arsenic typically results from chemical weathering of rich sediments and is most often found in oxidized forms surface water. The mobility controlled by its valence state also association with iron oxides minerals, the which are both influenced abiotic biotic processes aqueous environment. In this study, speciation methods were used to measure confirm presence reduced species water Fr...
