Parental investment in <i>Cinclus mexicanus</i> at 2-Mile Bridge: egg laying to fledging
Predator-prey interaction and case-building behavior
Breeding in <i>Sphyrapicus varius varius</i>
Comparison of Bee Bowls and Netting for Monitoring Native Bees
This study looked at the differences in bee community composition between estimates obtained from pan traps vs. netting. Comparing species richness, evenness and community composition between the two sampling types from the years 2009-2017 and 2009-2021. Based on a rate of bees caught per hour, with
Native ant (<i>Formica rufa, Formica fusca</i>), <i>Nicrophorus spp.</i> interactions at small mammal carcass resources in the southern Rocky Mountains, Gunnison National Forest, Colorado.
Competition for carcass resources can be fierce with a broad range of taxa vying for control of the nutrient rich resource. Arthropod competition for carcasses is well studied. Flies, beetles, and ants are common carcass utilizers. The burying beetle (Nicrophorus spp). is an obligate carrion breeder
The effect of a snow drift on temperature and plant growth
Variations in montane meadow flora (especially <i>Poa interior</i>) with moisture
Ant Behavioral Responses to Aphids Colonizing <i> Ligusticum porteri </i>
Ant-aphid mutualisms are keystone interactions that, if altered, have the potential to cause cascading, multitrophic effects on local arthropod and plant communities. In our study system, the flowering stalks of Ligusticum. porteri (Apiaceae) are colonized by the aphid Aphis asclepiadis, which relie
Snowmelt Timing Leads to Plasticity and Alters Natural Selection on Leaf Traits in <i> Ipomopsis </i>
Anthropogenic climate change is altering environments, which in turn has the potential to influence plant traits (through phenotypic plasticity) and natural selection. The effect of changing climate on the strength and direction of selection remains unresolved. In this study we quantified the plasti
Is Compensatory Growth Costly?
1. Compensatory growth is well-studied and exhibited across a variety of taxa, including plants, invertebrates, and a variety of vertebrates. Compensatory mechanisms allow individuals to recover from adverse conditions, potentially enhancing survival and fitness. However, to compensate for a low bod
How understory bee communities compare to open meadows in the Rocky Mountains
Forest associated species, bees and otherwise, are among the world's most vulnerable species due human activity such as deforestation. Even though bees are significant to ecosystem health by providing such important services as pollination, basic information on bee biodiversity and factors driving t
Variation of pollinator species at different times of day
Determining changes in floral volatile composition of <i> Ipomopsis aggregata </i> in response to nectar robbing and its associated microorganisms
Mutualisms involve complex relationships between multiple types of organisms. Traditionally, mutualisms like pollination have been studied using a pairwise perspective – only focusing on two individual species or groups of species with similar functions involved in the relationship. Including third-
Effects of clumping of <i> Delphinium barbeyi </i> on pollination
The spatial clustering of plants occurs for a variety of reasons, including the evolution of concentrated floral displays to attract more pollination. Within clusters, traits that attract pollinators may differ from non-cluster conditions– such as increasing floral display size andscent, which can c
Hydric succession of three levels on Quigley Creek
Development and structure of boldness and aggression in yellow-bellied marmots
The ontogeny of personality traits is crucial to understanding their ecological significance but has not yet been well-studied. We examined the development of two traits that are commonly correlated in a syndrome, boldness and aggression, in a long-term study of yellow-bellied marmots (Marmot flaviv
Testing how density affects caddisfly distribution along a detritus quality gradient
As ecosystems continue to change, the ability to find high-quality habitats is becoming a valuable skill. Caddisflies are often found in pond environments with a variety of habitat qualities, such as food (detritus) quality. Asynarchus nigriculus, being highly mobile and having a unique dietary need
Comparative study on pollinator visits to high elevation plant communities in Virginia Basin, Gothic, Colorado
Plant-pollinator networks are intricate systems that can give insight on a location’s biodiversity and response to environmental changes. By studying pollination networks at different elevations, researchers can evaluate how varying environmental conditions influence how plant and pollinator species
