A community approach to understanding patterns and processes on rocky subtidal reefs in the Salish Sea
The structuring of marine benthic communities is driven by a diverse set of ecological factors, each exerting its influence to differing degrees across all spatial and temporal scales. Here we’ve leveraged a decade of ... -
A Gene of Many Functions: Novel Roles for a Plant Epidermal Transcription Factor in Early Diverging Eudicots
The epidermal transcription factors MIXTA/MIXTA-like modulate the differentiation of distinct cell identities in the epidermis of land plants. This study explored the evolutionary history and function of the MIXTA-like ... -
A Grain Carried by the Flood: methods and data for global change ecology amidst a data deluge
Forecasting the responses of ecological systems to changing environment is a critical area of modern ecology research. An overwhelming amount of openly-available ecological and environmental data is emerging in service of ... -
A landscape approach to forecasting climate change impacts on geographic ranges and phenologies of plants in the Washington Cascades
As the pace of environmental change accelerates, biologists are transforming the discipline of ecology from a fundamentally descriptive science to one that can be used to generate skillful forecasts. Although important ... -
Alpine insects: physiology and evolution in cold, thin air
(2007)The dramatic environmental changes that occur along an altitudinal gradient and the harsh living conditions at high altitude profoundly affect the evolution and physiology of organisms. Organisms living along a mountain ... -
Analysis of plant gene expression responses to the pathogen and natural genetic engineer Agrobacterium tumefaciens
(2004)Agrobacterium tumefaciens genetically transforms its natural plant host and other eukaryotic cells, representing both an intriguing pathogen and a vehicle for genetic engineering. Host responses to this bacterium have not ... -
Arrested succession in old fields within a temperate rain forest
(2000)Vegetation of old fields in the temperate rain forest of the Queets River Valley, Olympic National Park, Washington, USA remains dominated by exotic herbs 60 years after abandonment. Exploratory vegetation analyses revealed ... -
Auxin-induced degradation dynamics and plant development
Development requires cells to send and receive information, often in the form of small molecules or peptides. An emerging theme in biology is that information can be encoded in the dynamics of signaling, not just in the ... -
Benefits of seed dispersal for plant populations and species diversity
Seed dispersal influences the diversity and distribution of plants in ecological communities, and animals are the major vector of dispersal in the world's most biodiverse ecosystems. Defaunation occurring at the global ... -
Benthic subtidal assemblages and ecological processes in urbanized seascapes of Puget Sound, Washington, USA
Urbanization is a major process altering nearshore habitats in many parts of the world. One important aspect of urbanization in marine settings is the proliferation of artificial structures, such as seawalls, breakwaters, ... -
Beyond DNA Compaction: An Emerging View of the Diverse Functions of Drosophila Sperm Nuclear Basic Proteins
While sperm of different animals exhibit morphologically distinct features, the overall themes of sperm nuclei are surprisingly similar among species. Sperm nuclei are extremely condensed and transcriptionally inert, and ... -
Biologic monitoring of environmental contaminants in marine (killer whale) and terrestrial (caribou, moose, and wolf) wildlife populations using scat samples
Wildlife are intimately associated with contaminated waters and polluted landscapes, serving as sentinels to the health of our shared environment. This project optimized trace analytic techniques for measuring toxicants ... -
Biology and Ecology of Hexacorallians in the San Juan Archipelago
Hexacorallians are one of the most conspicuous and dominant suspension feeders in temperate and tropical environments. While temperate hexacorallians are particularly diverse in the northeast Pacific, little work has been ... -
The biology and taxonomy of Pacific Northwest species of Phaeocollybia Heim (Agaricales, Cortinariaceae)
(1998)Investigation of the agaric genus Phaeocollybia (Cortinariaceae) in British Columbia, Washington, Oregon and California has led to a better understanding of the biology of the genus and resulted in a taxonomic revision of ... -
Biomechanics and dynamics of turning
(2005)In chapter one, I examine the extent to which a pelagic marine gastropod, Clione limacina, turns by changing its wingstroke kinematics versus shifting its tail position as a rudder. I find that there is no evidence for ... -
Biotic and Abiotic Drivers of Plant-Pollinator Interaction Rewiring
In this dissertation, I examine variation in plant-pollinator interaction patterns. I present two observational studies exploring drivers of interaction variation, followed by an experiment in which I demonstrate the effect ... -
Biotic and Abiotic Influences on Bull Kelp (Nereocystis luetkeana) Abundance and Distribution in the Salish Sea
Bull kelp, Nereocystis luetkeana, is an annual species of subtidal marine macroalgae that serves as major biogenic habitat in the Salish Sea of Washington State. Kelp forests are ecologically important because they provide ... -
Biotic interactions shift across temperature and ontogeny in an intertidal barnacle
Natural systems provide beneficial goods and services to humanity. To maintain these benefits, modern science is tasked with predicting how natural systems respond to global change. Understanding the ecological processes ... -
Boundaries and dynamics of biomes
(2014-02-24)Species are packed into biogeographic zones, where evolution can effectively operate independently to forge evolutionary novelty. Biomes are perhaps the most relevant unit of evolutionary progress, with the vast majority ...
