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 the Rocky Mountai

The data set “Snowpack_Snodgrass_AS.csv” consists of the snowpack data measured by the PhenoCams at each site up Snodgrass Mtn, Crested Butte, Co. To calculate snow depth each fall, we placed a 3-meter PVC pipe in the ground in the field of view of the PhenoCam. We spray painted 25 cm alternating in

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

Eavesdropping is recognizing and gleaning information from a communication intended for someone else. Eavesdropping on alarm calls can benefit eavesdroppers by decreasing the time they spend allocated to vigilance, giving them more time for other behaviors such as foraging. Although there have been

Ants are important members of most terrestrial ecosystems, and often forage in plant canopies where they occasionally participate in mutualisms with either the plants, or aphids that live on the plants. To participate in these mutualisms, the ants must first find them, and it is not clear how ants d

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

Innovation has transformed ecology and evolution, and understanding behaviors that lead to innovation success can have profound implications and applications in animal populations and human society. In past research, persistence, behavioral selectivity, and neophobia have influenced an individual’s

Anthropogenic influence over biodiversity has altered ecosystem functions. One important ecosystem function related to diversity is productivity. Plant richness has long been considered for determining productivity. Despite the importance of the relationships between diversity and productivity, thei

On a global scale, bees are important pollinators but face declining populations. In order to monitor the health of bee populations and communities, accurate sampling methods are needed. One common sampling protocol utilizes a combination of pan-trapping and sweep netting. While pan- trapping has it

This study examines whether climate change alters patterns of local adaptation in Boechera stricta (Brassicaceae). A common garden experiment was established in sites around the Rocky Mountain Biological Laboratory in Colorado. In the fall of 2017, Dr. Jill Anderson and her lab planted seeds from a

Maintaining high levels of self-fertilization within a population increases homozygosity, exposes deleterious alleles, and may cause inbreeding depression. Yet, many species of flowering plants have evolved to self-fertilize a majority of the time. Often, self-fertilization is favored over outcrossi

Dispersal is important for recolonization, migration and maintenance of local metapopulations and populations, in case of disruption in an animal's habitat. Morphology (wing loading and wing aspect ratio) and physiology (metabolic rates) are features that have been shown to explain dispersal process

Ecologists are always interested in studying populations of a certain area. There are many reasons for this, but two reasons include to see the change in distribution over time and because it can help tell about interactions between species. A traditional way of studying small mammal populations tha

Waser et al. (2016) found that road dust consistently reduces the pollen received by Ipomopsis aggregata flowers but does not consistently reduce seed set. Over three years we tested the hypothesis that the reason undusted plants do not have higher seed sets is that more of their fruits are eaten by
