Physical site characteristics for the ARCSS/TK stream dissolved organic carbon biodegradability (2011) data set.
The (ARCSSTK) did extensive research during 2009-2011 field seasons in Arctic Alaska. The objective of this data set was to measure the quantity and biodegradability of DOC from headwater streams and rivers across three geographic regions and across four natural ‘treatments’ (reference; thermokarst-; burned-, and thermokarst + burned-impacted streams) to evaluate which factors most strongly influence DOC quantity and biodegradablity at a watershed scale. This table provides physical site characteristics for the locations sampled for stream water biodegradability.

Eight Mile Lake Research Watershed, Thaw Gradient Extended sites: Physical properties of soil (temperature, moisture and thaw depth).
This data set contains meausrements of soil properties (soil moisture, soil temperature, thaw depth) of sites surrounding an eddy covariance tower. The purpose was to see how physical changes in the lanscape effect carbon fluxes measurede by the EC tower.
Eight Mile Lake Research Watershed, Thaw Gradient Extended sites: Physical data from land cover classes from an upland watershed undergoing permafrost thaw.
This data set contains meausrements of soil properties (depth to permafrost and depth of organc matter) from sites throughout the wathershed within certain land cover types identified by an unsupervised landcover classification. The purpose was to see how land cover classes differed in soil properties and if we could detect diffences in classes undergoing permafrost thaw that results in thermokarst.
Physical Attributes of the Hubbard Brook Valley Plots, 1995 - 1998 Survey Data
The valley-wide plots are a grid of 431 sites along fifteen N–S transects established at 500-m intervals spanning the entire Hubbard Brook Valley. Multiple above- and below- ground attributes were measured between 1995 and 1998. This dataset includes physical attribute data; tree inventory, soil data and other measurements are presented in separate datasets. These data were gathered as part of the Hubbard Brook Ecosystem Study (HBES). The HBES is a collaborative effort at the Hubbard Brook Experimental Forest, which is operated and maintained by the USDA Forest Service, Northern Research Station.
MCR LTER: Coral Reef: Community Dynamics: Physical Characteristics of Branching Acropora Patches and Species Richness and Abundances of Associated Fishes
Branching corals, like many in the genus Acropora, provide structurally complex habitats for reef fishes and other organisms. Fluctuations in the abundance, distribution and characteristics of staghorn Acroporid corals may contribute to changes in the abundance and species composition of reef fishes due to changes in the availability of shelter habitat and food. Farming damselfishes of the genus Stegastes occur in high abundances in staghorn thickets and actively defend food and nest space against organisms that threaten these resources. Here I examine the value of staghorn thickets as habitat for fishes, and how the presence of territorial farming damselfishes may influence the assemblage of fishes that associate with staghorn corals. Surveys of 185 Acropora pulchra thickets located in the lagoons surrounding the island of Moorea, French Polynesia revealed 85 species of fish from 25 families. Total fish abundance and species richness values ranged from no fish on a thicket to a high of 275 individuals and 26 species. Thicket area was the most important characteristic in explaining variation in attributes of the fish assemblage among staghorn thickets, with other characteristics explaining little of the species composition or trophic structure. Behavioral observations revealed that farming damselfishes were most aggressive toward corallivores, herbivores, and egg predators, while they ignored most carnivores and omnivores. Despite this pattern, I observed positive covariance between Stegastes and the group of fishes that elicited the strongest aggressive response when the effect of thicket area was removed, suggesting these fishes remain drawn to the resources produced or enhanced by Stegastes on A. pulchra thickets.
Soil chemical and physical property data for Green Lakes Valley, 1982 - 1983.
The genesis and water chemistry of two soil catenas and mineralogy of eolian dust were studied to evaluate the capacity of these soils to buffer acid conditions. Field and laboratory analyses of 50 soil pits and three eolian dust traps indicated that the surface horizons are mainly eolian dust accumulation and the subsurface horizons differed in texture, organic carbon percentage, bulk density, pH, concentration of soluble and exchangeable ions, dissolved organic carbon, and distribution and concentration of clay materials. The chemistry and mineralogy of the eolian dust resemble those of the surface horizons. Calcite, which increases soil buffering capacity, was found in the eolian dust. The eolian calcite probably comes from western Colorado, where limestone exposures are common. This natural liming process may reduce effects of acid rain on the aquatic system.
Soil chemical and physical property data for Martinelli slope, mid-1980s.
Soil pits were excavated at the Martinelli slope within the Boulder City Watershed. Soil profiles were described in the field and samples were analyzed in the laboratory for various constituents.
Soil chemical and physical property data for Saddle nodal plots, 1986.
Samples were collected from various soil horizons during installation of tension soil solution samplers adjacent to nodal plots in the Saddle. Excavation was limited to minimize disturbance. Consequently, complete soil profile descriptions were not made. Samples were analyzed in the laboratory for various constituents.
SGS-LTER GIS layer with detailed information on physical landmarks on Central Plains Experimental Range, Nunn, Colorado, USA 2012
This data package was produced by researchers working on the Shortgrass Steppe Long Term Ecological Research (SGS-LTER) Project, administered at Colorado State University. Long-term datasets and background information (proposals, reports, photographs, etc.) on the SGS-LTER project are contained in a comprehensive project collection within the Digital Collections of Colorado (http://digitool.library.colostate.edu/R/?func=collections&collection_id=3429). The data table and associated metadata document, which is generated in Ecological Metadata Language, may be available through other repositories serving the ecological research community and represent components of the larger SGS-LTER project collection.

Tramadol effects on physical performance and sustained attention during a 20-min indoor cycling time-trial: A randomised controlled trial
<p>Objectives: To investigate the effect of tramadol on performance during a 20-min cycling time-trial (Exper- iment 1), and to test whether sustained attention would be impaired during cycling after tramadol intake (Experiment 2). Design: Randomized, double-blind, placebo controlled trial. Methods: In Experiment 1, participants completed a cycling time-trial, 120-min after they ingested either tramadol or placebo. In Experiment 2, participants performed a visual oddball task during the time-trial. Electroencephalography measures (EEG) were recorded throughout the session. Results: In Experiment 1, average time-trial power output was higher in the tramadol vs. placebo condition (tramadol: 220 W vs. placebo: 209 W; p < 0.01). In Experiment 2, no differences between conditions were observed in the average power output (tramadol: 234 W vs. placebo: 230 W; p > 0.05). No behavioural differences were found between conditions in the oddball task. Crucially, the time frequency analysis in Experiment 2 revealed an overall lower target-locked power in the beta-band (p < 0.01), and higher alpha suppression (p < 0.01) in the tramadol vs. placebo condition. At baseline, EEG power spectrum was higher under tramadol than under placebo in Experiment 1 while the reverse was true for Experiment 2. Conclusions: Tramadol improved cycling power output in Experiment 1, but not in Experiment 2, which may be due to the simultaneous performance of a cognitive task. Interestingly enough, the EEG data in Experiment 2 pointed to an impact of tramadol on stimulus processing related to sustained attention. Trial registration: EudraCT number: 2015-005056-96.</p>
