Quality Assurance and Quality Control (QA/QC) of Meteorological Time Series Data for Billy Barr, East River, Colorado USA

A comprehensive Quality Assurance (QA) and Quality Control (QC) statistical framework consists of three major phases: Phase 1—Preliminary raw data sets exploration, including time formatting and combining datasets of different lengths and different time intervals; Phase 2—QA of the datasets, includi

East River Surface and Pore Water FTICR-MS Data Associated with “Implications of sample treatment on characterization of the riverine environmental metabolome”

Surface and pore water samples were collected from distributed locations around Meander A in East River (Crested Butte, CO, USA) during the summer of 2018. This dataset consists of the characterization of dissolved organic matter using 12 Tesla Fourier transform ion cyclotron resonance mass spectrom

East River Watershed Stable Water Isotope Data in Precipitation, Snowpack and Snowmelt 2016-2020

Stable water isotopes (d18O, d2H and d-excess) are important tracers in hydrologic research to understand water partitioning between vegetation, groundwater, and runoff but are rarely applied to large watersheds with persistent snowpack and complex topopgraphy. Data were collected for the Lawrence B

Sensor-based phenology from snowmelt experiment gradient, East River, Colorado, 2017 to 2020

The timing of snowmelt is a critical cue for the initiation of growth in mountain meadow ecosystems and can also impact the duration and magnitude of plant production. High frequency observations of species-level phenology are time consuming and require a high degree of expertise, and publicly avail

Does road dust affect reproduction of <i>Delphinium nelsonii</i> and <i>Ipomopsis aggregata</i>

In the United States, the 6.2 million kilometers of paved and unpaved public roads and roadsides represent about nineteen percent of the total land area of over nine million Km2 These roadways have major ecological impacts, one of which is dust pollution. When it comes to the effect of dust on plant

Effects of water addition on below- and above-ground carbon processes across a montane elevational gradient

Local temperature increases and more frequent extreme rainfall events are predicted effects of climate change at high latitudes (IPCC 2007). Precipitation regimes are also shifting, but science is less able to predict these patterns (IPCC 2007). Water balance is critical as it ultimately drives prim

Effect of Soil Metals on Pollination of Subalpine Wildflowers

Metals-rich soils can occur naturally or through human activity, such as mining. Plants growing in metal-rich soils often incorporate metals into their tissues; the concentration of these metals varies, and plants which concentrate the metals most strongly are termed hyperaccumulators. Accumulation

THE EFFECTS OF CLIMATE CHANGE ON THE TIMING AND ABUNDANCE OF DIPTERA IN A SUBALPINE MEADOW

Diptera play a critical role in alpine and subalpine ecosytems, though they are little studied in terms of what guides their timing and abundance. In order to reveal what cues dipteran timing this study was conducted for 24 years, using a Malaise trap to capture the insects, dipteran distributions w

Linking drift and benthic density along fishless to fish transitions in Rocky Mountain streams

The influence of predators on drift and benthic density is important for understanding prey community structure in freshwater streams. Drift activity of stream invertebrates in fishless streams does not differ between day and night, but when visual drift-feeding trout are present, stream invertebrat

Rocky Mountain Bombus pathogen survey: Are invasive plants affecting pathogen prevalence and intensity?

Parasites have the potential to alter population dynamics by decreasing fitness and increasing mortality of their hosts. Changes in ecosystems may also create scenarios that are more conducive to higher infection or parasitism. This survey examined parasitism of Bombus by Crithidia bombi, Nosema bom

On the spatial distribution and abundance of herbaceous plants in aspen and conifer forest understories: a test of neutral/statistical versus niche-based theories?

The purpose of this study is to test several macroecological statistical theories in the sub- alpine environment. Statistical theories are based on purely statistical assumptions, and these predictions were tested against measured values for macroecological metrics including the species-abundance di

Effect of a reduction in mountain stream flow on the diversity and quantity of benthic macroinvertebrates and the abundance of algae

The process of manually diverting water from stream channels for agricultural purposes, industrial uses, and other reasons is practiced universally worldwide. These diversions of water are primarily characterized by a reduction in total flow within the stream. This study examines the response of ben
