Reciprocal effects among the ant <i>Formica obscuripes</i> and the asters <i>Chrysothamnus viscidiflorus</i> and <i>Artemisia tridentata</i>
Variation in the structure and dynamics of bee assemblages across distinct montane meadows
Across different landscapes, plant abundance and richness change. Bee distributions may vary spatially in accordance to these differences in floral diversity. I used a habitat-based approach to investigate this hypothesis across three distinct meadow types: dry meadow, wet meadow-Veratrum and wet me

Aquatic invertebrate communities in old, new, and re-formed beaver ponds in the Trail Creek watershed
1. Beavers are ecosystem engineers. They alter the structure of their habitats when they cut woody vegetative material to create dams that result in ponds. Ponding slows water flow, resulting in fine sediment deposition. A wetland is created as the sediment continues to deposit. 2. The formation of
Investigating the potential mechanism behind bumble bee preference for Corydalis flowers inhabited by nectar specialist yeast
Flowering plants are in an evolutionary battle for the attention of pollinators to increase their fitness. However, microbes are increasingly recognized as key players in mediating interactions between plants and pollinators. Most studies of floral microbes have focused on the role of obligate necta
Variation in root morphology and allocation of <i>Androsace septentrionalis</i> along a natural elevation/climate gradient
Acoustic source localization using the acoustic ENSBox
The effects of altitude on the life history characteristics of yellow-bellied marmots <i>(Marmota flaviventris)</i>
Evidence for fine scale adjustments in circadian rhythms in yellow-bellied marmots according to burrow location, photoperiod, and local ambient temperature
Stem and canopy growth analysis in Picea Engelmannii with UAVs and field measurements
Forests play a crucial role in mitigating climate change by sequestering large amounts of carbon dioxide from the atmosphere, so it is critical to evaluate their capacity to store carbon over time. Existing research on forest carbon sequestration relies on field methods that do not allow for samplin
The reservoir cytoskeleton and a possible cytostomal homologue in Colacium (Euglenophyceae)
ABSTRACTThe reservoir cytoskeleton of Colacium Ehrenberg is formed of three bands of microtubules. The microtubules of the dorsal band (DMT) become doublets and are continuous with the longitudinal microtubules of the canal and, therefore, of the pellicle. A band of para‐reservoir microtubules (PMT)

An empirical study of acoustic source localization
A study of flora along the vertical gradient of Avery Mountain with special emphasis on the identification of ubiquitous species on the west-facing slope
Investigating the role of climate on juvenile Golden-mantled ground squirrel (Callospermophilus lateralis) growth and behavior
Changes to climate can have a variety of consequences on organisms across all taxa. Though we are seeing climate changes across the globe, these effects can often be greater in high-elevation regions. For mammals in these environments, climate change can alter phenology, survival, and reproduction.
The Natural History of Inbreeding and Outbreeding, Theoretical and Empirical Perspectives
Avian Diversity in Aspen and Conifer Forests :
In order to compare avian diversity (species richness and evenness) between aspen and conifer forest communities in Gothic, Colorado, point counts were conducted in three replicates of each habitat type. Additionally, tree density and light measurements were performed as a measure of structural comp
Some metabolic and nutritive aspects of community structure with particular reference to the role of invertebrates in food chains, food webs, and trophic structure in marine, fresh-water, and terrestr
Carrying the moral burden of safe fieldwork
Fieldwork in ecology and the environmental sciences often leads to negative physical and emotional outcomes for workers. I argue that this is largely due to an abdication of responsibility on the part of their supervisors, and that supervisors are charged with carrying three interlinked moral burden
