  • Early-successional vegetation dynamics and microsite preferences following post-fire forest restoration in southwestern Oregon

    Creator:
    Kayes, Lori J.
    Abstract:
    Reforestation-based restoration of severely burnt plantations is one of the primary management activities following wildfire on U.S. federal lands. Restoration effects on early-seral plant and cryptogam communities have not been documented. The objectives of this study were, in severely burnt plantations two to four years post-fire, to examine the: (1)...

  • Advances in Freshwater Cyanobacterial Genomics

    Creator:
    Brown, Nathaniel M.
    Abstract:
    Limnology is undergoing a transition to high-throughput -omic analysis of freshwater bacterial communities. An important first step in making the transition is to characterize several genomes that can be used as references to guide metagenome assembly and analysis. Here I characterize four new freshwater cyanobacterial genomes, a pair of lake...

  • Changing Climate, Changing Contexts : Variation in Rocky Intertidal Predator-prey Interactions Seen Through an Environmental Stress Framework

    Creator:
    Cerny-Chipman, Elizabeth B.
    Abstract:
    The multifaceted role of the environment in regulating the structure and dynamics of biological communities has long fascinated ecologists and motivated much debate and research. Now, in a time of accelerated global changes due to human impacts, the need to understand how the environment shapes communities has gained new urgency....

  • Linking marine communities and ecosystems : invertebrates mediate nutrient availability in intertidal communities

    Creator:
    Bracken, Matthew E.
    Abstract:
    While community ecologists have traditionally focused on local-scale processes, it has become apparent that a broader perspective, which explores the community-level ramifications of material fluxes within and between ecosystems, is necessary to effectively evaluate bottom-up influences on community structure and dynamics. In this dissertation, I employed ecosystem principles to understand...

  • Effects of environmental stress on intertidal mussel reproduction

    Creator:
    Petes, Laura E.
    Abstract:
    Environmental stress can negatively affect the ability of organisms to reproduce. Energetic trade-offs exist in all organisms, and under stress, energy may be allocated away from reproduction and towards physiological defense and repair mechanisms. The rocky intertidal environment is ideal for investigating the influence of environmental stress, as organisms are...

  • Cryptogam communities in forest and steppe ecosystems of Oregon, USA

    Creator:
    Root, Heather T.
    Abstract:
    I focus on addressing knowledge gaps relating to management of cryptogams in Oregon's public lands in Pseudotsuga menziesii-Tsuga heterophylla forests on the west side of the Cascade Range and dryland steppe in the Cascade Range's rainshadow. While a great deal of research has illustrated the importance of late-successional forests for...

  • So Long and Thanks for All the Sponge: Cryptic Intertidal Communities, Consequences of Ocean Acidification, and New Directions for Science Education

    Creator:
    Rickborn, Alissa J.
    Abstract:
    The current generation of scientists will be asked to mitigate climate change, stall biodiversity loss, and protect ecological communities. These are tasks that require a knowledge of both ecological and social systems to be undertaken successfully. Therefore, my dissertation spans the fields of community ecology and social sciences in an...

  • Yosemite region nitrogen deposition and patterns in the composition of lichen communities

    Creator:
    Hutten, Martin
    Abstract:
    This dissertation describes patterns in epiphytic macrolichen community composition along a nitrogen deposition gradient in the Yosemite region of the Sierra Nevada in California. This region is part of the largest federal air quality Class 1 designated air-shed in the western United States, covering the entire crest of the Sierra...

  • Three essays on food security, food assistance, and migration

    Creator:
    Lewin, Paul A.
    Abstract:
    This dissertation's three essays explore the determinants of food insecurity for rural farm households, the influence of rainfall variability and long-run changes in rainfall levels on the migration decisions of working-age household heads, and the distributional impacts in core and periphery regions of food assistance to households in the hinterland....

    Abstract:
    Background: Social interaction among peers on a campus of higher education has long been considered an important part of the college student experience, in particular for the first-term students transitioning into college life. Students who socially connect with peers on campus tend to persist at higher rates, while other benefits...
