Nowcasting the distribution of <i> Valeriana edulis </i> using climate driven population models
Climate change poses a unique problem for sessile species because individuals are unable to move to track their optimal habitat. Instead, population turnover governed by population processes must occur in order for the species distribution to change. Current methods to predict current and future spe

The impact of soil moisture, nectar production, and spectral reflectance on hummingbird visitation patterns to the Scarlet Gilia (Ipomopsis aggregata)
Climate change has brought intense disruptions to the natural patterns of growth and reproduction in sub-alpine ecosystems, generating changes to the food sources that Broad-tailed hummingbirds (Selasphorus platycerus), which breed in the Rocky Mountains, depend on. A hotter, dryer climate results i
Test Excavations at Site 41CD56 Colorado County, Texas
Site 41CD56 is an aboriginal site located on Crier Creek in northwestern Colorado County, Texas. Testing in October, 1983, revealed that moderate amounts of thermally altered chert/quartzite and lithic debitage were contained in sandy deposits varying from 20 to 110 cm in depth. Two burned rock accu
Spring Control of Cooley Spruce Gall Adelgid on Colorado Blue Spruce in Berks County, 1988
Abstract Fourteen treatments were applied to evaluate Cooley spruce gall adelgid on heavily infested 5-6-ft Colorado blue spruce Christmas trees. Each treatment was applied on 6 Apr to 4-tree replicates. Foliar treatments were completed by using a Solo Master 412 mistblower. Treatments were applied
Ecosystem Consequences of Soil Warming
Alpine plant spatial clumping modifies leaf surface temperature
Alpine plant communities are particularly susceptible to the impacts of climate change, which makes predicting how these communities will respond important for their conservation. This can be better predicted by understanding how the communities assemble, which is highly influenced by species intera
Testing the marginal value theorem on Bombus appositus and Bombus nevadensis
Previous studies on bumblebee foraging behavior found that bumblebees often exhibit optimal foraging behavior when collecting nectar and pollen. A popular theory is that bumblebee foraging can be represented by the marginal value theorem (MVT). This summer, I observed the foraging behavior of Bombus

Colorado Potato Beetle Control with Biological and Synthetic Insecticides, Pasquotank County, 1989
Abstract Su perior' potatoes were planted near Weeksville, N.C. Single row plots, 6 . 1 B long with rows 1.06 m apart were replicated 4 times in a randomized complete block design. Treatments were applied using a COa pressurized sprayer with a single hollow cone nozzle (18 X) operating at 60 psi to
Examining the effects of environmental variation on sociality in yellow-bellied marmots utilizing a within-individual centering approach
The relationship between environmental variation and fitness has been well established. However, fitness may also be indirectly impacted by environmental variation through the modulation of social behavior. We aim to quantify the effects of environmental variation on sociality, specifically social r
