Potentilla demographic and environmental data for Rainbow Meadows, Elk Meadows, and Cabin Clearing, 2018 - 2020.
To understand parent-hybrid dynamics in cinquefoil (Potentilla) species in the Colorado Rocky Mountains, I am estimating environmental overlap among parents and hybrids, interbreeding among parents and hybrids, and hybrid population growth in multiple natural populations at NWT and (not included her
Potentilla flowering phenology for Cabin Clearing, Elk Meadows and Rainbow Meadows, 2019.
To understand parent-hybrid dynamics in cinquefoil (Potentilla) species in the Colorado Rocky Mountains, I am estimating environmental overlap among parents and hybrids, interbreeding among parents and hybrids, and hybrid population growth in multiple natural populations at NWT and (not included her

Facilitation strength across environmental and beneficiary trait gradients in stream communities
Ecosystem engineers modify habitats in ways that facilitate other community members by ameliorating harsh conditions. The strength of such facilitation is predicted to be influenced by both beneficiary traits and abiotic context. One key trait of animals that could control the strength of facilitati
Evolution of hydrothermal fluids from the deep porphyry environment to the shallow epithermal environment, The
The current understanding of magmatic-hydrothermal processes resulting in the formation of porphyry and epithermal deposits is based on case studies that focused on deposits such as Santa Rita porphyry copper deposit in New Mexico, the Refugio porphyry gold deposit in Chile, and the Summitville high
Facies reconstruction and detrital zircon geochronology of the Ingleside/Casper Formation
Mixed siliciclastic-carbonate deposits of the Ingleside/Casper Formation in northern Colorado and southeastern Wyoming developed along the flanks of the Ancestral Front Range during the Late Paleozoic. This study establishes a sedimentological model for the Ingleside/Casper Formation along with usin
Rural-to-Urban Water Transfers: Measuring Direct Foregone Benefits of Irrigation Water under Uncertain Water Supplies
Irrigation water from a southeastern Colorado county has been sold to distant municipalities. The county's junior water right delivered limited and uncertain water supplies which were used on relatively poor soils. The ability of water markets to allocate water to the highest-valued use was addresse
Water in the West : perspectives from an Upper Basin tributary of the Colorado River
This thesis explores two institutional frameworks utilized in the governance of water in the Southwest of the United States through how they deliver, or fail to deliver, complex equity. These are (1) the legal framework and (2) cooperative agreements. This is done through a case study in the Roaring
Invasion and restoration of western rivers dominated by Tamarix spp.
Fifty years ago, riparian habitats were not recognized for their extensive and critical contributions to wildlife and the ecosystem function of watersheds. This changed as riparian values were identified and documented, and the science of riparian ecology developed steadily. Papers in this volume ra
Landscape, Science, and Social Reproduction
This chapter discusses the arc of Carolyn Merchant’s direct and indirect influences on work, particularly now forming a bridge between completed landscape history of Point Reyes National Seashore here in northern California, and developing a new focus on the history of the Rocky Mountain Biological
Contact Metamorphism of the Mancos Shale: Impacts on Solute Release and Weatherability in the East River Valley, Gothic, CO
Alteration of rocks by contact metamorphism directly impacts rock pore structure and mineralogy, potentially decreasing weathering susceptibility and altering water residence times and release rates of aqueous solutes. Mountainous catchments, which can often be metamorphosed, are important for water
Disintegration of the leaf economic spectrum within and across Quaking aspen (<i>Populus tremuloides</i>) genotypes
1. The leaf economic spectrum (LES) describes consistent and strong correlations among plant functional traits in a multidimensional trait space, which reflects fast or slow rate of return on carbon investment in leaves. These relationships between LES functional traits are strong at global scales a
Conditional Exploitation and Context-Dependent Fitness Consequences of Pollination Mutualisms
The aboveground primary productivity within each of four areas, differing in length of the snow-free season, was determined in a high subalpine (3380 m) herbaceous meadow in Colorado. Net productivity, minus losses to herbivores, ranged from 114 g -m™ - yr“ in the area with the shortest snow-free pe
Effects of Climate Change on Plants, Pollinators and Their Interactions
1. Changes from historic weather patterns have affected the phenology of many organisms worldwide. Altered phenology can introduce organisms to novel abiotic conditions during growth and modify species interactions, both of which could drive changes in reproduction. 2. We explored how climate change
Examining the impact of pollen diet composition on bee development and lifespan
Pollen is the sole protein source for most bees and the largest component of their larval diets.
Host-parasite ecology of <i>Baetis bicaudatus</i> mayflies and <i>Gasteromermis sp.</i> nematodes in high-altitude streams
Parasite-induced changes to host dispersal potentially influence the distribution of parasites and infection risk for hosts. Gasteromermis is a castrating endoparasitic nematode that infects both males and female mayflies (Baetis bicaudatus) but feminizes male hosts and manipulates them to disperse
Correspondence with DOE on Route Back of W Mountain
Attached for your information is a copy of my corrispondence with the DOE concerning the route back of W Mountain. I feel that the tailings should be moved 6ut of the flood plain. If they have to go somewhere, the Landfill site and the route back of W Mountain appear to make the most sense. I talked
