Raw plastic counts and calculated plastic deposition rates for 11 National Atmospheric Deposition Program (NADP) sites in the western USA recorded from 2017-2019. Samples were collected to determine plastic deposition rates in remote locations and identify the potential sources of plastic to the atm

In-person undergraduate research experiences (UREs) promote students’ integration into careers in life science research. In 2020, the COVID-19 pandemic prompted institutions hosting summer URE programs to offer them remotely, raising questions about whether undergraduates who participate in remote r

The COVID-19 pandemic shut down undergraduate research programs across the United States. A group of 23 colleges, universities, and research institutes hosted remote under- graduate research programs in the life sciences during Summer 2020. Given the unprec- edented offering of remote programs, we c

Pandemic-induced restrictions on research are now ubiquitous. We urge administrators and policy-makers to recognize that field researchers—especially those early in their careers—face unique challenges, even if restrictions last only a month or two. Bans on travel, hiring, and facility use are forci

Training in science, technology, engineering, and mathematics (STEM) is a top priority for driving economic growth and maintaining technological competitiveness. We propose that exposure to a rigorous research program as an undergraduate leads to success in a research STEM career. We compared the sc

Anthropogenically induced climate change is expected to effect numerous climatic alterations pertinent to ecosystems, including increased mean global temperature and altered precipitation regimes. High-elevation ecosystems are especially sensitive to climatic changes because slight fluctuations in f

The fitness of the non-feeding adult caddisfly, Asynarchus nigriculus is largely dependent on the accumulation of nutrients during its larval stage. The energy obtained during this time is then allocated into growth and development for the adult insect. This allocation of energy may be constrained b

I investigated the pollination ecology of Cardamine. Cordifolia, and how pollinators affected fruit and seed production especially in relation to variation in herbivory and habitat type in 2 different sites. Site 1 was more exposed to the sunlight and site 2 was less exposed to the sunlight. I inves

A 14 year warming experiment being conducted in a subalpine meadow has resulted in several physical changes, including advanced date of snowmelt, a decrease in soil moisture, and increased soil temperature in heated plots versus control plots. These microclimate changes have led to a shift in plant

Mayflies in high-elevation streams in Colorado are more vulnerable to risk of predation based on their relative drift propensisties. Baetis bicaudatis, a mayfly that has high drift propensity, has been shown to respond to predation risk by accelerating its metamorphosis into an adult, which results

Albinos plants are usually discriminated by their pollinators. Exist the possibility that other pollinator drive a reproductive isolation on this plants. To observe if an albino of a plant commonly pollinated by hummingbirds can be selected by other pollinator we used the F1s of albinos of Ipomopsis

Many aphid species, on a wide variety of plants, are tended by ants. We tested whether the relationship between the ant species Formica obscuripes and an aphid species on rabbitbrush (Chrysothamnus viscidiflorus) was a mutualism and, if so, whether it was obligate or facultative. Using a fully facto

The Red-naped sapsucker creates a nest cavity in aspen woodlands each year, required by other bird spp. for nesting, and spends much of its foraging time in willow wetlands. This study attempted to determine a) how does proximity of potential nest trees to forest edge and willows affect the sapsucke

I studied survivorship from the period of egg laying to winter diapause in a population of E. gillettii (Nymphalidae). I investigated if fitness, in the context of hatching and succesful development to diapause was related to egg cluster size, habitat parameters, or both, and if there were factors a

In a nutshell, Tri-State sold too much of its existing capacity to other utilities, leaving it short over the next few years. Now Tri-State may compound the mistake and raise rates further by building expensive units that solve neither a short-term nor a long-term problem. None of Tri-State’s severa
