Effects of Alpine Shrub Cover on Territorial Male White-Crown Sparrows Densities.
Avian populations at high elevation are well-adapted to extreme and variable abiotic conditions. Species have adapted efficient foraging strategies, as well as well-timed nest incubation patterns. These behavioral traits are essential in order for parents to meet their metabolic needs while simultan
Roles of Stridulation in Nicophorus investigator.
Stridulation is a key behavior to determining survival in Nicrophorus investigator. In this paper, the roles it plays in competition over a carcass, burying process, and larval development have been studied. Their ability to stridulate was manipulated through clipping part of their plectra and they
Fungal Phytopathogens Decrease Plant-Insect Interactions.
Rusts are pathogens of rapidly growing plant tissue and are of particular concern in agricultural settings due to their reduction of plant fitness. These phytopathogens depend heavily on abiotic features such as humidity, temperature, and UV strength, and with a changing climate, the rust ranges may
Investigating Herbivore Relationships to Boechera stricta in a Climate Change Context.
Boechera stricta is a mustard that grows naturally throughout a wide range of altitudes in the Colorado Rocky Mountains. B. stricta has a variety of natural herbivores, which makes it an interesting system in which to study how plant-herbivore relationships vary over an elevational gradient. Through
A behavior study of <i>Castor canadensis</i>
How does relative refuge angle influence escape behavior: an empirical test with yellow-bellied marmot.
Flight initiation distance, or FID, is the distance between a predator and its prey at which the prey decides to flee. FID is influenced by several internal and external factors, which influence the potential costs and benefits of escape. For refuging prey, their path to a refuge may force them to g
The Effects of Elevation on Herbivorous Insect Communities and the Host Plant Boechera stricta.
Changes in elevation have strong influences on the taxonomic richness and population densities of terrestrial ecosystems (Hawkins et. al, 2013, McCain and Grytnes 2010, Rahbek 1995). These gradients are caused by changes in precipitation, temperature, and several other key environmental factors asso
Consequences of Pollination Neighborhood Composition and Pollinator Communities
Climate change may affect individuals within a species differently dependent on sex, leading to skewed sex ratios. This paper considers the effect of mating environment on seed production in the dioecious plant species, Valeriana edulis. The study was conducted in female dominated populations where
