Linking the shelf/break processes to coastal hypoxia in the upwelling core of the central California Current System

Coastal upwelling supports highly productive ecosystems in eastern boundary currents that provide ecologically and economically important habitats, e.g. the California Current System. However, the upwelling of nutrient-rich deep waters poses ecosystem risks as well as benefits, as cold upwelled waters are increasingly enriched in CO2 and depleted in oxygen. Because the mechanisms responsible for changing oxygen levels within the California Current System are not fully understood, our ability to characterize the duration and extent of exposure to hypoxia is limited, thus preventing a proper assessment of habitat vulnerability, and how management tools can be applied to address local impacts of globally driven changes. By collecting continuous bottom-water time-series measurements offshore the Bodega Marine Reserve (BMR), and by synthesizing and analyzing historical and proposed data, we can quantify the multiple mechanisms that can account for hypoxic events by relating temperature, salinity and oxygen variability to forcing mechanisms and source water types. This work will help to assemble a historic record of oxygen variability and hypoxic conditions observed in and around the BMR, and will contribute to a growing body of literature aimed at better understanding sharp changes in chemistry of our coastal upwelling system.

Interactive effects of biotic disturbance and extreme warming events on the maintenance of genotypic diversity within a marine foundation species

The extreme ocean warming events off the California coast during the summers of 2014 and 2015 greatly affected ecosystem and community dynamics on the Bodega Marine Reserve (BMR). The timing of these extreme warming events occurred during critical periods of peak productivity for a key foundation species on BMR, the seagrass Zostera marina. Following the summer warming events, Zostera within BMR experienced heavy grazing pressure by migrating Brant geese. Previous research utilizing the BMR seagrass ecosystem demonstrated that greater genotypic diversity is an important factor in Zostera recovery from disturbance by geese grazing. Additionally, high genotypic diversity positively influenced resilience of Zostera meadows to extreme warming during the 2003 heatwave across Europe. We are conducting a mesocosm experiment that will tease apart the independent and interactive effects of extreme warming and geese grazing pressure on the maintenance of genotypic diversity in Zostera.

Effects of interacting climate & biotic drivers on the population dynamics of the Ranchman’s tiger moth (Arctia virginalis)

In this project we are examining the impact of abiotic and biotic drivers on the population dynamics of the Ranchman’s tiger moth (Arctia virginalis) across a gradient of temperature and precipitation, and varying biotic interactors. A mechanistic understanding of the effects of abiotic and biotic drivers on the Ranchman’s tiger moth from previous long-term study at Bodega Bay Marine Reserve will allow us to test how the impacts of these drivers vary depending on both climate and biotic context.

Climatic controls on the biogeochemical cycling of phosphorus in the critical zone

My research will fill fundamental gaps in current scientific knowledge concerning P cycling in the CZ by investigating three objectives to satisfy the ISEECI Aim 3: (1) for the first time, evaluate the W&S model in temperate ecosystems experiencing comparatively unique Mediterranean and arid-type climates (essentially no precipitation during the growing season) with low-P containing parent material; (2) assess the applicability of the W&S model to describe changes in soil P pools as a function of depth into the regolith, where surficial soils are more weathered (pedogenically old) and deep saprolite materials are least weathered (pedogenically young); and (3) use climosequences as surrogates for predicting climate change effects on soil P pools and transformations.

Implications of forest demography and community dynamics for predicting future distributions under climate change

My research is focused on forest population and community responses to climate change at the scale of species ranges. Range shifts and community composition changes are important ecological consequences of climate change. Demographic responses to the environment, biotic conditions, and spatial dynamics underlie patterns in species occurrence and abundance. Predicting how well a species will perform in new climatic conditions based on requires that we understand the relationship between species performance and probability of occurrence. Alternatively, predicting changes in a community in response to climate across a species range requires that we understand variation in species interactions across the range. To address these two research goals I utilize forestry data (FIA) and dendroecological data from field sites that I have established in the Sierra Nevada and San Jacinto mountain ranges.

Back to the Future of Sea Urchins: Predicting climate change vulnerability in California urchin populations using historical datasets

Despite the biological, biogeochemical, and economic importance of the sea urchin to California’s coastal systems, little is known about the resilience of the urchin industry, and the ecosystem that supports it, in the face of global climate change and ocean acidification (OA). Acidifying ocean water has the potential to harm calcium carbonate structures within the urchin body at crucial life stages, thereby potentially reducing population viability over time. In collaboration with Dr. Steve Schroeter, this project utilizes long-term juvenile urchin datasets to assess how calcification within urchin populations along the California coast may have been impacted by chronic and acute acidification events over the past 25 years, and seeks to understand if analysis of historical data enables us to generate predictive proxies of future climate change impacts on coastal systems.[/fusion_text][/two_third][/fullwidth][fullwidth background_color=”#0096b5″ background_image=”” background_parallax=”none” enable_mobile=”no” parallax_speed=”0.3″ background_repeat=”no-repeat” background_position=”left top” video_url=”” video_aspect_ratio=”16:9″ video_webm=”” video_mp4=”” video_ogv=”” video_preview_image=”” overlay_color=”” overlay_opacity=”0.5″ video_mute=”yes” video_loop=”yes” fade=”no” border_size=”0px” border_color=”” border_style=”solid” padding_top=”5″ padding_bottom=”5″ padding_left=”” padding_right=”” hundred_percent=”yes” equal_height_columns=”no” hide_on_mobile=”no” menu_anchor=”” class=”” id=””][fusion_text]

Assembling long-term datasets to quantify the effects of global climate change on freshwater ecosystems and water resources

Freshwater habitats are the most threatened habitat type worldwide, while also being the most important resource necessary for the survival of humans and many other species. A thorough understanding of the impacts of global change on freshwater systems will allow us to efficiently and safely manage water resources. A serious impediment arises in this understanding when we lack long-term data, which may be necessary to understand these impacts on relevant time scales under realistic natural conditions. By assembling a time series of climate data to associate with the various monitoring and experimental studies conducted at these reserves, we could gain a rich and thorough understanding of how climate interacts with freshwater environments in many different real-world ecosystems.[/fusion_text][/two_third][/fullwidth][fusion_text]
