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

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

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

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

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

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

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

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

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

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

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

Climate change has been changing plant community systems worldwide. These observations can be seen over a broad range, when resurveyed. Recording these changes in plant community structure is necessary if future plant migration studies are to be done. Herbarium data was expanded using historically s

Global climate change-driven changes in phenology affect populations of alpine meadow wildflowers and their pollinators through direct and indirect effects. Earlier snowmelt in montane regions, caused by a warming climate, results in earlier blooming date and longer blooming period of wildflowers su

For years the standard of care in burying beetles has been a male and female, bi- parental care, but is it really? The intent of this experiment was to measure the success of burying beetle larvae produced under four different parental conditions after carcass preparation; 50 pairs of Nicrophorus in

Increasing urbanization has led to the expansion of human infrastructure, including road networks. Current research has shown that roads have important ecological effects, ranging from habitat fragmentation to contamination of water runoff. This study examined the potential effects of roads on the r

Plants systems rely on a variety of resources to survive and reproduce. The amount and quality of pollen a flower receives can determine not only the number of seeds that are produced, but also whether they will be viable or not. The purpose of the study looked at the relationship between the amount

Roads potentially impact nearly one-fifth of the continental United States. Runoff, traffic disturbance, and maintenance associated with roads can affect both the abiotic and biotic features of roadside ecosystems. Species along unpaved roads are particularly susceptible to road dust effects. Plant

Dietary specialization on “toxic” or unfavorable pollens has multiple evolutionary origins in many bee families, despite such pollen being unsuitable for most generalist bee species. Pollen specialization on unsuitable pollen types must confer other evolutionary benefits; an anti-­‐parasitism functi

Plant-­‐fungal symbioses are found in ecosystems worldwide, but relatively little is known about how these two organisms affect each other. This study sought to shed light on this topic. The first experiment tested to see if the presence of an endophyte (genus Epichloë) effected the decomposition ra
