To what extent does road dust affect sexual reproduction in different plant species?
How do distributions of belowground grass-fungal symbioses change over altitudinal gradients in the Colorado Rocky Mountains?
Fungal symbionts are pervasive and crucial components of terrestrial ecosystems. They can often reduce the effects of stressors such as drought and heat and can increase nutrient and water uptake for plants. Because of these roles, fungal symbionts may be important in mitigating the stressors of cli
Effects of early snowmelt and frost on plant-pollinator interactions.
As a result of climate change, plants are experiencing shifts in flowering phenology due to early snowmelt, and thus becoming more susceptible to damage from spring frost events. These direct effects of snowmelt and frost on plants can indirectly impact plant- pollinator interactions, yet few studie
Do birds differentiate white noise and deterministic chaos? A playback experiment.
Evocative sounds are known to elicit heightened responses from receivers across animal taxa. Many species of caregivers specifically have been shown to have increased arousal from infant baboon screams providing a unique conspecific identification for baboon mothers to discriminate their young from
Floral herbivory: a possible mechanism maintaining a flower color polymorphism in a selfing species, Boechera stricta.
Many studies have shown that pollinators are largely responsible for changing and maintaining flower color morph frequencies in nature. However, the preferences of pollinators do not always reflect observed frequencies in nature, especially in self-pollinating species. Thus, non-pollinator forces co
The effects of primary and secondary nectar robbing of Ipomopsis aggregata on hummingbird visitation.
Nectar robbers feed on the nectar obtained through holes that have been chewed into the flower. This behavior often leads to a reduction in effective pollination because nectar robbers avoid floral reproductive structures (Inouye 1980). Primary nectar robbers puncture the flower, creating an opening
Why doesn't nectar robbing decrease seed set in some bee-pollinated plants?
Herbal impact on nectar robbing is species specific by pollinator species (Maloof and Inouye 2014). Unlike hummingbird pollinated plants, some bee-pollinated species does not suffer reproductive loss by nectar robbing (Maloof 2001, Mayer et al. 2014, Maloof and Inouye 2014). This observational study
Causes and consequences of dominant and subdominant plant species effects on ecosystem function: using above-and belowground traits in an alpine meadow system
While there has been extensive studies done on how dominant affect community dynamics and ecosystem function, fewer studies address the relative influence of dominant vs. subdominant species to affect systems. Further, not enough studies have been done addressing the role of dominant vs. subdominant
Elevational and temporal variation in Ipomopsis floral and vegetative traits.
Exploring the geographical and temporal movement of hybrid zones provides practical evidence for conservation biologists investigating the dynamics of species invasions (Buggs 2007). Genetically based clines in floral traits can also help us to understand potential adaptation in responses to climate
Geographic variation in flowering phenology in Boechera stricta: testing for adaptive response to climate across the species range
As climate continues to shift, species existing over broad and variable ranges must exhibit the ability to adapt functional traits to novel environmental conditions. In this study, I used a large-scale common garden experiment to examine the variation in flowering time of 137 Boechera stricta (Brass

Pocket gopher activity across elevation gradients.
In ecology it is important to understand the limits of a species range and what their behaviors are within their range. Thomomys talpoides (Northern Pocket Gopher) and its relatives have been studied extensively at lower elevations ( 2700m). We asked what mechanism(s) (elevation, edaphic factors) de
An Epichloe endophyte alters the ecology of Poa leptocoma.
Determining mechanisms behind species ranges is vital to creating the most accurate models of species distributions under climate change. Mutualisms are an important factor to consider when examining mechanisms behind range limits of host plants, as they can have a large influence on community organ
