My research is focused on the effects that functional traits have on demographic fitness in perennial graminoid species. I investigate how inter- and intra-specific variations in key function traits related to drought tolerance and plant energy economics affect vital rates in plant populations. These variations reflect different life history strategies and ultimately differences in demographic fitness observed along environmental gradients.

I am interested in the linkages between habitat heterogeneity, life history, and metapopulation stability. My dissertation is focused on understanding the role of spring-fed streams to Yellowstone cutthroat trout. I use observational field studies, genomic techniques, and statistical models to understand individual behavior and population dynamics and demographics across riverscapes. Through my research I aim to provide resources managers with a mechanistic understanding of the benefits of alternative conservation strategies.

I am interested in learning how we can extrapolate from fossilized leaves to a broader understanding of an ecosystem at large. Leaves are just one part of a plant, but they can carry a lot of information about how that plant interacts with its environment. To that end, I’m interested in researching the relationships between fossil leaf functional traits, climate, and leaf architecture.

My research is centered around evolutionary spatial dynamics. Specifically I am interested in how the process of species shifting their ranges may result in decreased genetic diversity and an increase in genetic load which may affect the persistence of species even after a successful range shift.

Meredith is interested in understanding the influence of climate change and environmental
factors on aquatic communities that occupy high alpine lakes. Meredith aims to describe
the relationships between snowpack and ice phenology as they relate to biological
limnology, zooplankton community structure, and trout growth and reproduction under
the lens of climate change. Meredith utilizes a combination of field collection, laboratory
techniques, and remote sensing methods to better understand the seasonal dynamics
of this often-understudied ecosystem.
Meredith received her M.S. degree from the School of Aquatic and Fishery Sciences
at the University of Washington in Seattle, WA (2015). Her research focused on the
early marine growth and physiology of out-migrating juvenile salmon in the Salish
Sea and beyond. After completing her M.S. degree, Meredith accepted a professional
appointment as a Research Biologist at the Northwest Fisheries Science Center in Seattle
WA (2016-2022). During this time, she worked to understand and model the biological
and oceanographic factors influencing salmon growth in the Salish Sea, Columbia River
Estuary, and Northern California Current.
Beyond research, Meredith enjoys spending her free time in the mountains rock climbing
and backcountry skiing. Rest days include crossword puzzles and cuddling with her

Broadly, I am interested in how organisms cope with environmental variation from changes in their cellular composition to responses at the population level. Currently, we are identifying how bumble bees respond to temperature variation over short and long-term timescales. Upcoming work will focus on the effects of temperature on floral resources (pollen), and to what extent diet influences physiology. We hope to better understand how bumble bees alter their cellular composition across variable conditions as we identify the cascading effects of climate on these crucial pollinators.

I study abundance-occupancy relationships in a small mammal community of central Kenya savanna. I test the predictions of two influential ecological hypotheses; 1) colonization-extinction rates hypothesis, which predicts restricted, rare species require dispersal from the surrounding region to maintain occupancy, whereas widespread, abundant species do not require such dispersal even though such dispersal will bolster their abundance, 2) resource-use hypothesis, that predicts resource generalism at the species level is the mechanism that leads to the fitness advantages exhibited by common and widespread species.

I am obsessed with birds in general, and bird behavior and evolution more specifically. During my master's work on a gull colony in Washington I realized how fascinating hybridization is, and that hybridizing species can help us understand the process of speciation. Despite the fact that gulls are really cool, I have switched study systems and am currently conducting a comparative study of reproductive isolation in songbirds. Several pairs of closely related passerine species hybridize quite extensively but other pairs do not hybridize even though they sing similar songs, have similar ecologies, and share geographic ranges. I am hoping to associate patterns of environmental niche divergence, song divergence, and genomic divergence with patterns of hybridization or its converse, complete reproductive isolation. Ideally, I will be able to identify consistent patterns in the evolution of reproductive isolation across North American passerines.

I am interested in the early Eocene paleobotanic record, which here in Wyoming's Wind River Basin captures the Early Eocene Climatic Optimum (EECO). This event is characterized by some of the warmest temperatures in the past 65 million years, making it an ideal place to examine the plant response to warming in both vegetation structure and community composition. Because this climate event is so significant, it also lends itself well to analyzing the plant-insect interactions and their variability over the warming period.

I am broadly interested in how animals perceive and select resources on the landscape and the extent to which they can adjust behaviors to navigate habitats altered by humans. Currently, I am studying habitat selection-based fitness trade-offs, site fidelity, and full annual cycle spatial use of Loggerhead Shrikes nesting in sagebrush habitats disturbed by energy development. Additionally, I am examining how fine-scale habitat heterogeneity influences inter-annual nest site selection in sagebrush obligate songbirds and how fine-scale habitat elements influence landscape level biodiversity. I am also eager to contribute to the broader wildlife conservation community beyond research. To that end, I have worked with friends and colleagues to develop and run bird banding station to monitor avian migration in Laramie Wyoming that offers internship opportunities to undergraduate students and experiential learning to the public.
