Research: Impacts of shifting fire regimes on ecosystem carbon and nutrient cycling and biodiversity
Department: Earth System Science

We are conducting a large-scale survey to investigate the effect of long-term changes in fire regimes on ecosystem carbon and nutrient cycling and plant biodiversity across the globe. Fire frequencies are changing dramatically across the world, and increasing in frequency throughout most of the US; consequently, we hope to better understand the effect of changes in fire frequency on ecosystems. Our project contains collaborators in a number of organizations and our findings will have implications for how fire is managed in our research areas. Tony will be focusing his investigation on our work in National Parks, where there are a number of avenues to communicate our scientific findings to the broader community. We hope that our results will inform fire management policy to balance the need to conserve biodiversity, maintain healthy carbon and nutrient cycles, and reduce the risk of severe wildfire.

Research: Effects of ocean acidification on seagrass ecosystem structure and function
Department: Biology, Hopkins Marine Station

This project is a part of doctoral thesis work investigating the influences of ocean acidification on the structure, ecological interactions, and ecosystem function of a key coastal marine ecosystems associated with seagrasses. We are using low pH caused by natural CO2 venting activities (on Ischia Island, Italy) to examine how acidification may alter the composition and diversity of marine invertebrate species and functional groups, and the resulting rates of grazing and decomposition of plant material. We utilized pH gradients at vents to quantify seagrass litter decomposition rates in litter bag experiments, as well as the composition of invertebrates, microbes and fungi along the gradient. Physical variables and seawater chemistry are simultaneously characterized along the gradient. Ultimately, the project will increase our understanding of how ocean acidification will affect important ecosystem functions such as decomposition of organic matter and nutrient cycling.

Research: Effects of oxygen, temperature, and body size on the habitable range of red abalone
Department: Geological Sciences

Anthropogenic climate change has caused dramatic ocean warming and de-oxygenation. Marine ecosystems are fragile, and important fishery species like red abalone will likely experience a rapid decline in their habitable range. We will use the 'metabolic index' as a framework for mapping abalone habitable ranges. This is the first time this promising energetics-based approach has been used to predict future organismal habitability against high-resolution oxygen/temperature predictions for the U.S. west coast. These predictions of future habitable range will be have high utility in conservation and fisheries planning. We also plan to test the role of body size in temperature-dependent hypoxia. Smaller body sizes should be favored in low oxygen/high temperature environments due to a higher surface area/volume ratio. We hope that this project will show how oxygen thresholds vary with temperature in larval to adult abalone to test this physiological principle.

Research: Using Psychology and Neuroeconomics Methods to Study Pro-Environmental Behavior
Department: Psychology/EIPER

This project will involve supporting several ongoing studies that use a combination of approaches from psychology, economics, and neuroscience to study human decision-making on environmental issues. These include: studying ways to change commuter behavior to utilize public transportation options using a combination of messaging, signed pledges, and incentives as part of a controlled behavioral intervention trial with survey and choice experiment components; using a suite of neuro-imaging experiments to predict the efficacy of campaigns by environmental nonprofits at fostering advocacy and conservation funding, the mechanisms that motivate species conservation, and what motivates the success of nature imagery on social media; and opportunities to utilize behavioral economics approaches to reduce energy consumption both in the residential and transportation sectors through the creation of materials for literature review.

Research: Constructing nature, environment, and environmentalism in environmental education
Department: Graduate School of Education and Woods Institute

How we conceive of nature and what it means to be an environmentalist have the potential to influence our attitudes and behaviors with regard to the environment. Environmental and nature education experiences play a key role in shaping some of those conceptions for many of today's adolescents, and thus represent an important opportunity to affect the environmental choices of the next generation. This project combines qualitative methods (interviews, ethnographic observation, qualitative assessment of student writing samples) and quantitative methods (linguistic word count, implicit association testing, quantitative content analyses of student writing and mainstream media) from environmental education, social psychology, and linguistics, to explore (1) how educators construct 'environmentalist' and 'environmentalism'with students, (2) what opportunities students have to feel included in the environmental movement, and (3) how students more broadly construct their own individual relationships to nature.

Research: Managing flood risk through land use policy
Department: Earth System Science

In this study, we will focus on the siting of hazardous industrial facilities, which are particularly dangerous because they may spill contaminants or toxins if flooded. By examining where flood-prone hazardous industrial facilities coincide with high levels of social vulnerability (e.g., agriculture-dependent, low-income, or otherwise disadvantaged communities), we will assess the spatial variation of high-risk communities (many flood-prone industrial facilities, highly vulnerable) and low-risk communities (few flood-prone facilities, low vulnerability). This project will combine the spatial analysis with an assessment of local land use regulations to determine if and how municipalities exacerbate or reduce flood risk from hazardous industrial facilities. Ultimately, the findings from the study will provide new insight into the consequences of flood risk management policy today, particularly for socially disadvantaged groups.

Research: Determining trace metal distributions in vegetation and soils in a mining-impacted headwaters catchment
Department: Earth System Science

This research project will integrate field sampling of vegetation in riparian and floodplain environments with remotely sensed vegetation information. The sampling will focus on intra- and inter-species foliar chemistry across three adjacent watersheds in Colorado, located proximal to the Rocky Mountain Biological Laboratory (RMBL). Two of the watersheds (Coal and Slate Creeks) are highly impacted by naturally occurring mineralization and historical mining activities, whereas one of the watersheds (East River) is relatively pristine. Coal Creek is the local water supply for the town of Crested Butte, CO and understanding metal distributions and release to surface waters is a central concern of the local community. This project seeks to first understand the distribution of metals across the floodplain and riparian vegetation in relation to stream and sediment concentrations. Assuming we find metal accumulation in plants growing in meta-contaminated sites, the project will then explore whether metal accumulation translates into a biochemical signature that is detectable at leaf-level and ideally, using airborne remote sensing. The ultimate goal of the project is to determine if airborne remote sensing data can be used to identify and map the distributions of metals in sediments using foliar chemistry or foliar response as an indicator.

Research: Estimating global extinction threat levels in Odonata (dragonflies & damselflies)
Department: Geological Sciences

Approximately 45% of the described species belonging to the insect order Odonata (dragonflies and damselflies) have been assessed for extinction threat. This is a relatively high percentage compared to other classes and orders of invertebrate animals, yet the threat status for the majority of species remains unknown, preventing a comprehensive conservation response. We will use the IUCN Red List threat statuses of 2716 assessed species of Odonata to create a logistic regression model of extinction threat status as predicted by four macroecological variables: body size, geographic range, habitat breadth, and sighting history. This model will then be applied to the remaining unassessed species for which we all have all four predictor variables. All four predictors variables are associated with extinction threat status in other living animal groups and with extinction versus survival in ancient extinction events recorded by the fossil record. The objective of this study is to rapidly evaluate the likely threat status for large numbers of species that have not been formally evaluated for threat status, thereby, quickly identifying the unassessed species most likely to be at risk of extinction and enabling more comprehensive conservation response at the landscape scale. The resulting list of estimated threat levels will complement the IUCN Red List and other formal assessment programs by providing a means for selecting species and geographic regions for highest priority.

Research: Modern-day dodos: designing protected areas for the world's-largest, heavily-hunted land crab
Department: Biology, Hopkins Marine Station

Weighing in at over 4kg and spanning up to a meter across, the coconut crab (Birgus latro) is among the largest native land animals on many Indo-Pacific islands. This gargantuan, jungle-dwelling crab has been hunted for hundreds of years, but growth of human populations and habitat destruction have increasingly caused localized crab extinctions around the world. Despite its ecological, cultural, and nutritional importance to many island nations, we have a very poor understanding of the crab's ecology and population trends. An improved understanding of both the coconut crab's ecology and the impacts of traditional crab hunters are critical for assessing the threats that it currently faces and for tailoring effective conservation measures to meet these challenges. The primary objective of this project is to improve understanding of the critical habitat, home range, and current ecological challenges of the coconut crab (Birgus latro). Towards these goals, our ongoing project aims to a) analyze the movements of coconut crab using GPS tag data to understand their habitat preferences and b) assess anthropologically-informed interviews with indigenous coconut crab hunters to understand the magnitude of their impacts and the potential for alternate harvest strategies.

Research: Development of new catalysts for sustainable plastics
Department: Chemistry

The aim of this interdisciplinary project is to combine computational chemistry, polymer chemistry and material science to develop new catalysts and processes for generating biodegradable plastics. This research is working towards reducing the effects of plastics on the environment by establishing chemical design principles that will enable the development of practical technologies for inventing future fully recyclable polymeric materials and for recycling or creatively reusing important existing polymeric materials. Main components of the project include rationally designing new selective catalysts for generating biodegradable polymers as well as chemically recycling these materials at the end of their useful life.

Research: Conservation Paleobiology in the Caribbean
Department: Biology

We propose to use recently excavated fossils (representing approximately 10,000 ybp to present) from the Caribbean islands of Hispaniola and Puerto Rico, combined with climate records and modern species occurrence data, to forecast how climate change will impact the remaining native mammals. Previous studies by the Hadly lab have linked these extinctions to both climate change and human activities through the archeological record, but have yet to connect these patterns with concrete conservation planning. To accomplish this, we will produce maps of species/climate associations from the last glacial maximum, present, and 50-100 years into the future using IPCC projections.

Research: Understanding stresses of climate change and soil arsenic on rice yield
Department: Earth System Science

The goal of this project is to asses to what extent elevated temperature and atmospheric CO2 affect the movement of arsenic from the bulk soil to the rhizosphere and ultimately into the rice root. To this end, the geochemistry of the soil and rhizosphere, specifically changes in arsenic speciation and mobility, and rice root physiology will help to understand the fate of arsenic within the soil-rice continuum.

Research: The effect of prescribed burns on Yurok & Karuk tribes and forests in Northern California
Department: Anthropology

We plan to assess tribal prescribed burning practices through ecological monitoring, interviews, and monitoring harvesting to evaluate if these practices alter resource abundance and access as intended. To expand this assessment, we combine aerial photographs (1944-2016) and satellite imagery to compare historical and current prairie characteristics throughout Yurok and Karuk ancestral territories. The aim is to evaluate how long-term fire exclusion may have altered fire-dependent ecological communities.

Research: Assessing the performance and effectiveness of past groundwater management experiences in California
Department: Law School

The Sustainable Groundwater Management Act (SGMA), enacted by the state legislature in 2014, represents California's first statewide regime for groundwater management. The goal of this project is to assess the performance of a set of 16 case studies, including adjudications, special act districts, voluntary groundwater management plans, and county ordinances. This research will be used in conjunction with a related case study project investigating the role of geophysical data on groundwater management decisions and the governance structure(s) emerging under SGMA. Jointly, this work will be used to help local government agencies and water managers in deciding how to form Groundwater Sustainability Agencies (GSAs) under SGMA, and in identifying policy alternatives to achieve sustainable management in each groundwater basin, as required under SGMA.

Research: Effects of agricultural intensity on biodiversity via analysis of species interaction networks
Department: Biology

This project will consider the effects of agricultural intensification on multiple species interactions by constructing plant-pollinator, plant-herbivore, plant-seed disperser, and bird-insect interaction networks. It will compare food resource diversity, wildlife diversity, and network structure between monoculture farms, diversified agriculture (farms that provide resources to wildlife through purposeful restoration techniques), and natural areas on the central California coast. This study's findings can be useful in designing effective agricultural management strategies for biodiversity conservation, and it will also provide a comprehensive dataset of multiple interaction networks, a scarce but vital resource for understanding ecological community dynamics.

Department: Civil & Environmental Engineering (CEE)

Within this context of environmental sustainability and business, this project draws on theories and methods from multiple disciplines – including psychology, sociology, education, public policy, philosophy, and economics – to examine the integration of environmental sustainability within business management education. More specifically, this project will use data from in-depth qualitative interviews of business students to develop insights into three questions: 1) What and how business students are learning and thinking about sustainability issues in a corporate context?, 2) How is the social influence of their peers influencing their beliefs and behaviors?, and 3) What are the main barriers to changing these beliefs, and behaviors? These insights will inform the design of controlled behavioral intervention experiments to further test ideas about business students’ attitudes and behaviors towards environmental sustainability.

Research: Simulating Seasonal Cycles of the Colorado River Basin: Nitrogen Cycling Insights and Implications for U(IV) Release
Department: Civil Environmental Engineering

Throughout the Colorado River Basin, uranium persists as a relic contaminant of former ore processing activities in fine-grained, organic-rich sediments found within the floodplain alluvium. We hypothesize that when seasonally elevated groundwater levels recede and the subsurface system becomes anoxic, nitrate diffuses into the reduced interiors of organic-rich sediments and becomes readily available for denitrification, the stepwise anaerobic reduction of nitrate/nitrite to dinitrogen gas. Using a series of diffusion-limited flow chambers with organic-rich sediment from Rifle, CO, this research will simulate seasonal groundwater trends observed in the field over an accelerated 12-week period in the laboratory.
