Carbon storage in U.S. Pacific Northwest coastal dunes : the role of invasive beachgrasses and sand supply

Creator:: Stepanek, John
Abstract:: As global atmospheric carbon emissions continue to rise, scientists and land managers are increasingly looking to natural ecosystems to sequester and store carbon to buffer the impacts of climate change. Despite their small geographic size, many coastal ecosystems such as salt marshes, seagrass meadows, and mangroves sequester large amounts of...

Investigating the Role of Dune Grasses, Carbon Storage, and Marine Nutrient Subsidies to the Functions and Services of U.S. Central Atlantic Coastal Dune Ecosystems

Creator:: Jay, Katya R.
Abstract:: Sandy beaches and dunes cover approximately one-third of the world’s ice-free coastlines and provide ecosystem services including coastal protection, recreation, wildlife habitat, and carbon sequestration. These dynamic interface habitats are variably shaped by wind, waves, sedimentary processes, and vegetation feedbacks. Positive biophysical feedbacks lead to the formation of vegetated coastal...

Coastal Dunes as Meta-Ecosystems: Connecting Marine Subsidies to Dune Ecosystem Functions on the U.S. Pacific Northwest Coast

Creator:: Constant, Vanessa
Abstract:: Ecological communities are connected in space and time through the transfer of energy, materials, and organisms, together known as ecological subsidies. These ecological subsidies can have substantial effects on community structure, function, and services, especially when the connections are between communities with contrasting productivity. At the ocean-land interface, low productivity...

Coastal Dune Ecology, Geomorphology, and Ecosystem Services : How Invasive Beachgrasses, their Interactions, and Sediment Dynamics Shape U.S. Pacific Northwest Dunes

Creator:: Biel, Reuben G.
Abstract:: Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...

The Range, Abundance, Spread, and Biophysical Effects of a Novel, Invasive Beachgrass Hybrid, Ammophila arenaria × A. breviligulata, on U.S. Pacific Northwest Coastal Dunes

Creator:: Askerooth, Risa
Abstract:: Non-native ecosystem engineers, which modify the structure and function of their ecosystems, are often a particularly concerning and costly group of invasive species. Such organisms may have substantial impacts on ecosystem services, or the benefits that humans derive from their ecosystems. Many factors play a role in the invasion success...

Hybridization of Non-Native Dune-Building Beachgrasses on the U.S. Pacific Northwest Coast: Characterization of Functional Morphology, Hybrid Swarm Composition, and Ecological Consequences of Ammophila arenaria × A. breviligulata

Creator:: Mostow, Rebecca S.
Abstract:: The rates of biological introductions and invasions are increasing, driving up the associated harms to ecosystems and economies. The spread and effects of invasive organisms depend on the specifics of the introduction, the character of the invaded ecosystem, and multiple traits of the invasive organism itself. One mechanism by which...

Macrophyte wrack on sandy beaches of the US Pacific Northwest is linked to proximity of source habitat, ocean upwelling, and beach morphology

Creator:: Reimer, Jessica N., Hacker, Sally D., Menge, Bruce A., and Ruggiero, Peter
Abstract:: Marine macrophyte wrack (macroalgae and seagrasses) frequently washes onto beaches but little is known about the factors controlling its biogeographic variability. We report on a large-scale study of macrophyte wrack deposition patterns on the US Pacific Northwest coast. We measured macrophyte wrack on 12 sandy beach sites from southern Washington...

The Role of Vegetation in Determining Dune Morphology, Exposure to Sea-Level Rise, and Storm-Induced Coastal Hazards : A U.S. Pacific Northwest Perspective

Creator:: Ruggiero, Peter, Hacker, Sally, Seabloom, Eric, and Zarnetske, Phoebe
Abstract:: This chapter is part of Barrier Dynamics and Response to Changing Climate. Coastal foredunes are often the “first line of defense” for backshore infrastructure from the hazards of erosion and flooding, and they are key components of coastal ecosystems. The shape and growth characteristics of coastal foredunes, typically characterized by...

Coastal protection and conservation on sandy beaches and dunes : Context-dependent tradeoffs in ecosystem service supply

Creator:: Ruggiero, Peter, Seabloom, Eric W., Hacker, Sally D., Biel, Reuben G., and Cohn, Nicholas
Abstract:: Managing multiple ecosystem services (ESs) across landscapes presents a central challenge for ecosystem-based management, because services often exhibit spatiotemporal variation and weak associations with co-occurring ESs. Further focus on the mechanistic relationships among ESs and their underlying biophysical processes provides greater insight into the causes of variation and covariation among...

Life history and morphological shifts in an intertidal seagrass following multiple disturbances

Creator:: Ruesink, Jennifer L., Fitzpatrick, John P., Dumbauld, Brett R., Hacker, Sally D., Trimble, Alan C., Wagner, Eric L., and Wisehart, Lorena M.
Abstract:: Disturbance regimes differ in type, magnitude, and frequency, but few field experiments have considered compounded effects of disturbance. In this study, we characterized gap recovery after complete removal of eelgrass (Zostera marina) in Willapa Bay, Washington, USA. In separate experiments, we imposed two disturbance types – shoot damage and shoot...
