Context dependent biotic interactions control plant abundance across altitudinal environmental gradients

Climate change is causing species with non-overlapping ranges to come in contact, and a key challenge is to predict the consequences of such species re-shuffling. Experiments on plants have focused largely on novel competitive interactions; other species interactions, such as plant–microbe symbioses

The effects of ungulate herbivory and nutrient variation on pollen reciept in Ipomopsis aggregata

The purpose of this study was to investigate the effects of ungulate herbivory (clipped, unclipped) and nutrient variation (ambient, water added, fertilizer and water added) on conspecific and heterospecific pollen receipt to Ipomopsis aggregata. I found that both clipping and adding nutrients influ

Ecosystems impacts of climate change: snowmelt timing, species diversity, and plant productivity

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

From grain to floodplain: Evaluating heterogeneity of floodplain hydrostratigraphy using sedimentology, geophysics, and remote sensing

Floodplain stratigraphy, a major structural element of alluvial aquifers, is a fundamental component of floodplain heterogeneity, hydraulic conductivity, and connectivity. Watershed-scale hydrological models often simplify floodplains by modeling them as largely homogeneous, which inherently overloo

Colorado Potato Beetle Control, Johnston County, 1988

Abstract 'Atlantic' potatoes were planted 14 Apr, near Benson, NC. Single row plots, 10 ft long on 42 inch centers were replicated 4 times in a randomized complete block design. Alleys of 5 ft separated replicates. Treatments were applied using a CO2 pressurized sprayer with a single hollow cone noz

Spatial and Temporal Patterns of Coexistence in Closely Related <i>Rhyacophila</i> (Trichoptera) Species

Environmental change affects the survival, interaction and co-existence of species within an ecosystem. We studied multiple species of Rhyacophila, a primitive genus of caddisfly that, in its larval state, lives at the bottom of cold, oxygen rich and fast flowing streams. Previous research has shown

Changes of dispersal ability in an isolated population

Dispersal is a core mechanism in the maintenance of metapopulations. It maintains genetic diversity by connecting subpopulations and generates new populations to replace those that die out. However, as populations become more isolated, as occurs in habitat fragmentation, dispersal becomes more diffi

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

Folsom Point Diggings: The Johnson Site in the Foothills of Larimer County, Colorado

The Johnson site is a Folsom occupation in Larimer County, Colorado. T. Russell Johnson discovered the site in 1935, which led to excavations by the Colorado Museum of Natural History in 1936 and later work in 1960 by the University of Wyoming. Little is known of the site due to limited reporting of
