An analysis of fossil identification guides to improve data reporting in citizen science programs
(2020-04)An increasing number of organizations use untrained volunteers to gather scientific data. This citizen science movement builds enthusiasm for science by engaging the public, as well as providing a way to gather large amounts ... -
Light-Driven Permanent Charge Separation across a Hybrid Zero-Dimensional/Two-Dimensional Interface
(2020-04)We report the first demonstration of light-driven permanent charge separation across an ultrathin solid-state zero-dimensional (0D)/2D hybrid interface by coupling photoactive Sn-doped In2O3 nanocrystals with monolayer ... -
Long-Range Exciton Diffusion in Two-Dimensional Assemblies of Cesium Lead Bromide Perovskite Nanocrystals
(2020-05)Förster resonant energy transfer (FRET)-mediated exciton diffusion through artificial nanoscale building block assemblies could be used as an optoelectronic design element to transport energy. However, so far, nanocrystal ... -
The relationship between genome size and metabolic rate in extant vertebrates
(2020-01)Genome size has long been hypothesized to affect the metabolic rate in various groups of animals. The mechanism behind this proposed association is the nucleotypic effect, in which large nucleus and cell sizes influence ... -
How Does Magnetic Reconnection Drive the Early-stage Evolution of Coronal Mass Ejections?
(2020-04)Theoretically, coronal mass ejection (CME) kinematics are related to magnetic reconnection processes in the solar corona. However, the current quantitative understanding of this relationship is based on the analysis of ... -
The urgency of transforming the Midwestern U.S. landscape into more than corn and soybean
(2020-05)The current agri-food system emerged out of a desire to provide an inexpensive and secure food supply. Yet even before COVID-19, the abundant agricultural production of the Midwestern United States was generated amid a ... -
Forest Cover Change, Households’ Livelihoods, Trade-Offs, and Constraints Associated with Plantation Forests in Poor Upland-Rural Landscapes: Evidence from North Central Vietnam
(2020-05)Vietnam’s forests have experienced a notable transformation over the past 20 years from net deforestation to reforestation and expanding forests. Continued reforestation that aims to achieve further economic and environmental ... -
Food web controls on mercury fluxes and fate in the Colorado River, Grand Canyon
(2020-05)Mercury (Hg) biomagnification in aquatic food webs is a global concern; yet, the ways species traits and interactions mediate these fluxes remain poorly understood. Few pathways dominated Hg flux in the Colorado River ... -
Biosynthesis of the modified tetrapyrroles - the pigments of life
(2021-01)Modified tetrapyrroles are large macrocyclic compounds, consisting of diverse conjugation and metal chelation systems and imparting an array of colors to the biological structures that contain them. Tetrapyrroles represent ... -
Modeling Partially Surveyed Point Process Data: Inferring Spatial Point Intensity of Geomagnetic Anomalies
(2020-06)Many former military training sites contain unexploded ordnance (UXO) and require environmental remediation. For the first phase of UXO remediation, locations of geomagnetic anomalies are recorded over a subregion of the ... -
Agent-Based Models for Collective Animal Movement: Proximity-Induced State Switching
(2021-08)Animal movement is a complex phenomenon where individual movement patterns can be influenced by a variety of factors including the animal’s current activity, available terrain and habitat, and locations of other animals. ... -
Trampling Effects on Vegetation of the Trail Corridors of North Rocky Mountain Forests
(1974-08)The management of trails should be based on knowledge of the effects of humans on them; most of the available information has been reviewed by Speight (1973), Stankey & Lime (1973), and Liddle (1975). Observations of ... -
Tracking the migration of Pacific Golden-Plovers from nonbreeding grounds at Moorea, French Polynesia, using Pinpoint GPS-Argos tags
(2020-04)We used Pinpoint GPS-Argos tags to track migration of Pacific Golden-Plovers Pluvialis fulva in 2017 and 2018 from Moorea Island, at the extreme southeastern edge of the species’ winter range. Of 20 tagged birds, 13 uploaded ... -
American Indian young adults display diminished cardiovascular and cortisol responses to acute psychological stress
(2020-04)American Indian adults are at an increased risk for cardiovascular disease compared with non-Hispanic white adults. Scant research exists examining the underlying physiological and psychological mechanisms associated with ... -
Investigation of the role of infusate properties related to midline catheter failure in an ovine model
(2020-08)Purpose Infusate osmolarity, pH, and cytotoxicity were investigated as risk factors for midline catheter failure. Methods An experimental, randomized, controlled, blinded trial was conducted using an ovine model. Two ... -
Ecological effects of weather modification: effect of late snow melt on Festuca idahoensis meadows
(1974)Diversity, cover and productivity of Festuca idahoensis meadows become progressively lower as one moves: (1) from deep-soil to shallow-soil sites, or (2) from sites that melt out in mid-May to sites that melt in late May ... -
Pinus albicaulis in Central Montana: Environment, Vegetation and Production
(1974-07)Nineteen apparently climax, non-krumholz, whitebark pine (Pinus albicaulis) forests were sampled at 2490-2930 m in the Rocky Mountains of S-Central Montana. The understory of these forests is strongly dominated by Vaccinium ... -
Exotic invasion of timberline vegetation, northern Rocky Mountains, USA
(1990)Thirty-five exotic species were found in vegetation characteristic of Northern Rocky Mountain timberlines. At least 20 percent were intentionally introduced along road-sides. The diversity of invading exotics declined from ... -
Seeing whitebark pine in a northern Rocky Mountain (USA) landscape: notes for a field trip
(1990)The changing role of whitebark pine (Pinus albicaulis) along an altitudinal gradient typical of the Northern Rocky Mountains (USA) can be seen from the gondolas at the "Big Sky" resort near Bozeman, MT. Whitebark pine ... -
Berry production in three whitebark pine forest types
(1990)In the whitebark pine lwhortleberry (Pinus albicaulis/Vaccinium scoparium) habitat type of southwestern Montana, whortleberry plants produced seven to 69 berries I m• X yr in 1974. In subalpine fir (Abies lasiocarpa) habitat ...
