Sagebrush Team

PhD Assistantship Announcements

Interdisciplinary PhD Research Fellowships in Social and Ecological Resilience of the Southern Idaho Sagebrush Steppe Ecosystem

Up to five Ph.D. research fellowships are available to join a collaborative, interdisciplinary team focusing on the social an ecological resilience of the sagebrush steppe ecosystem of the Columbia Plateau and northern Great Basin in southern Idaho. This region is a mosaic of public lands, private ranches, agricultural parcels, and areas experiencing rapid urban and recreational development. The social and ecological components, structures and processes within this ecosystem are rapidly changing as a result of population growth, economic opportunities, policy changes, land conversion, climate change, invasive species and shifts in disturbance regimes. To capture the range of variation in the system and determine thresholds for resilience, the student and faculty team will evaluate the characteristics and impacts of these drivers in study areas across a climate gradient that include minimally altered to highly impacted rangelands. With funding from the National Science Foundations Integrative Graduate Education and Research Traineeship program (IGERT), the students will pursue interlinked dissertation projects important for the overall theme, and work together to identify and address interdisciplinary issues critical for development of effective planning and policy for future resilience of this threatened system.  The team will interact with members of five other IGERT-sponsored student/faculty teams pursuing similar objectives in other ecosystems in the Pacific Northwest and Costa Rica. This opportunity is especially appropriate for students seeking to develop skills for interdisciplinary collaboration and team-based research that addresses complex problems involving interacting human and natural systems.

PhD Assistantship in Plant Ecology

We seek a highly motivated PhD student to participate in a project focusing on plant community responses to environmental changes in sagebrush ecosystems, which include fire, climate, invasive species, and land conversion. The student will identify plant community factors and/or processes affecting ecosystem resiliency in response to changing disturbance regimes. Topics may include plant community composition, habitat types, and species interactions that identify a gradient of resiliency.  Species interactions beyond plant-plant interactions may further affect resiliency and include plant-insect, animal and microbial interactions. Many opportunities exist to integrate these research topics with other sagebrush steppe team members focused on biogeochemical cycling, ecohydrology, wildlife ecology, and rural social systems across a wide range of spatial and temporal scales. Contact Beth Newingham (beth@uidaho.edu), Lee Vierling (leev@uidaho.edu) and Dave Tank (dtank@uidaho.edu) for more information.

PhD Assistantship in Ecohydrology

We seek a highly motivated PhD student to participate in a project focusing on the interactions between ecological and hydrological patterns and processes in sagebrush ecosystems undergoing changing disturbance regimes and anthropogenic influences, including climate change, invasive species, and land conversion.  Resiliency to these drivers of change can be assessed by examining changes in water status and flux in the soil and plant environment, which may be mediated by soil-plant-microbial interactions. The sagebrush steppe team seeks a student interested in topics such as 1) effects of changing climate regimes (snow to rain-dominated) and/or 2) the effects of plant community structure changes on water dynamics and feedbacks on vegetation. These spatiotemporal dynamics include changes in snow redistribution, interception, evaporation, transpiration, sublimation, and soil water content and fluxes. Many opportunities exist to integrate these research topics with other sagebrush steppe team members focused on biogeochemical cycling, plant ecology, wildlife ecology, and rural social systems across a wide range of spatial and temporal scales.  Contact Beth Newingham (beth@uidaho.edu), Tim Link (tlink@uidaho.edu), and Lee Vierling (leev@uidaho.edu) for more information.

PhD Assistantship in Biogeochemical Cycling           

We seek a highly motivated PhD student to participate in a project focusing on biogeochemical responses to changes in the structure and function of sagebrush ecosystems, resulting from urban sprawl, climate change, invasive species and shifts in disturbance regimes. Quantifying changes in biogeochemical cycling is fundamental to understanding the resilience of sagebrush ecosystems as they respond to these drivers of change across spatial and temporal scales. We seek a student with keen interest in studying biogeochemical pools and fluxes of C, N and/or other nutrients in the context of developing indices for quantifying ecosystem resilience under a rapidly changing environment. Projects are encouraged that incorporate soil, plant, atmospheric, and/or microbial interactions.  Many opportunities exist to integrate these research topics with other team members focused on ecohydrology, plant ecology, wildlife ecology, and rural social systems across a wide range of spatial and temporal scales. Contact Contact Jodi Johnson-Maynard (jmaynard@uidaho.edu), Lee Vierling (leev@uidaho.edu) or Beth Newingham (beth@uidaho.edu) for more information.

PhD Assistantship in Animal Ecology

We seek a highly motivated and qualified PhD student to evaluate the resiliency of animal populations and communities occupying sagebrush steppe systems.  This research project will focus upon species-specific and community-level assessments of animals across major environmental gradients within sagebrush steppe.  The focus of the project will include: 1) examining how different focal taxa  (e.g. reptiles, amphibians, mammals, and/or birds) respond to key environmental and landuse gradients in sagebrush steppe, 2) determining the relationship between environmental gradients and community group composition/function, and 3) modeling how climatic and/or landuse changes will affect the resilience of these species and communities. Many opportunities exist to integrate these research topics with other team members focused on ecohydrology, plant ecology, biogeochemical cycling, and rural social systems across a wide range of spatial and temporal scales. Contact Janet Rachlow (jrachlow@uidaho.edu), Kerri Vierling (kerriv@uidaho.edu) and Lisette Waits (lwaits@uidaho.edu) for more information.

PhD assistantship in Rural Social Systems

We seek a highly motivated and qualified PhD student to pursue analyses of differences in human communities with respect to their impact on and openness to protection and restoration of sagebrush habitat. Applicants with a strong background in sociology are preferred, but students with significant and relevant backgrounds in social sciences will be considered as well. The research project will focus on social factors affecting ecological degradation including: 1) introduction of invasive species, 2) exurban and other development patterns, 3) grazing and off-road recreation, 4) fire suppression and 5) carbon-based climate change. Characteristics of interest include the degree to which institutions (e.g., education, tourist economy, state and regional governments) and nonprofit organizations support or resist restoration and contribute to or work against degradation, the presence or absence of social or creative capital, the impact of social class and varying levels of access to political and economic power (local, state and national), and the impact of tax policies and decision-making for diminishing oversight and regulation of public lands. Many opportunities exist to integrate these research topics with other team members focused on ecohydrology, plant ecology, biogeochemical cycling, and wildlife ecology. Contact Patrick Gillham (gillham@uidaho.edu), Leontina Hormel (lhormel@uidaho.edu), and J.D. Wulfhorst (jd@uidaho.edu) for more information.

Post-doc, weathering biogeochemistry, Washington State University

We have an immediate opening for a 24-month postdoc to join a team commencing NSF/ETBC-funded research into how chemical weathering mechanisms, and the chemistry of the terrestrial hydrosphere, are affected by rhizospheric processes. Our approach is experimental, with mycorrhizal trees growing in replicated hydrologic columns on which we can do detailed mass balances, as well as microscopic studies of the microbial biofilms that attach the tree root systems to mineral surfaces. We hypothesize that key weathering processes are micro-localized within these biofilms. We will use multi-scale reactive transport modeling to constrain our interpretations.

We want the postdoc to take principal responsibility for the column experiments (including manipulations with tracers), and relating column-scale biogeochemical mass balances to microscopic processes. Applicants with a variety of backgrounds will be considered; the ideal person's portfolio would include hydrology. (S)he will join an outstanding team of researchers with backgrounds in plant ecology, soil chemistry, rhizosphere microbiology, hydrogeology/biogeochemistry, transport modeling, and various genera of environmental microscopy. Opportunities for professional advancement are commensurately broad at Washington's land grant institution.

National Research Council Post-doctoral Position with the US Environmental Protection Agency and Washington State University, Vancouver
Modeling surface water N loading and removal for the nation: Foundation for ecosystem services assessment
The U.S. Environmental Protection Agency's Ecosystem Services Research Program seeks and individual to contribute to an ongoing, multi-year effort to characterize N-related ecosystem services and human impacts on these services within the US.  In the continental US, inputs of reactive nitrogen (N) to the terrestrial biosphere have increased by nearly five-fold over natural background rates due to activities associated with transportation, and food, fiber, and energy production.  A number of recent modeling efforts (e.g. SPARROW, NEWS, and others) have focused on linking anthropogenic N enrichment with N loading to surface freshwaters and the coastal zone at regional and global scales.  Yet, much work remains to be done comparing and interpreting output from existing regional and national scale models as well as enhancing the spatial and temporal resolution of these models to increase their utility to managers and policy-makers.  

It is expected that the postdoctoral fellow in this position will work closely with Dr. John Harrison (Washington State University -Vancouver) to implement spatially explicit models of aquatic N loading, thereby enhancing understanding of sources, patterns, and controls of N inputs to surface fresh waters and the coastal zone, as well as the potential impacts of these inputs on ecosystem services.  It is anticipated that this effort will be coordinated with complementary efforts to estimate N inputs, outputs, and removal within many ecosystem types within the US, including wetlands, riparian areas, and river networks (headwater streams, perennial streams, and large rivers).  Qualifications: a Ph.D. degree in biogeochemistry, biogeochemical modeling, limnology, marine or estuarine ecology, or related field.  The primary work location will be the Freshwater Ecology Branch of the Western Ecology Division (WED) located in Corvallis, Oregon.  The Associate will work with scientists across EPA as part of a national EPA program examining the impacts of nitrogen within EPA's Ecosystem Services Research Program.

Project Description
Here we present a Research Opportunity with the goal of elucidating how changing climate will influence carbon cycling on the Colorado Plateau. Global climate change presents one of the most pressing scientific and political challenges of our time, yet major uncertainties remain for predicting how ecosystems will respond to changes in temperature and/or precipitation. These uncertainties constrain our ability to successfully manage national lands and hinder the prediction of future global carbon cycling and attendant climate feedbacks. Understanding the links between changing climate and ecosystem function is particularly important for the ecosystems of the Colorado Plateau, as climatic change is predicted to be notably strong there and, in conjunction with the large proportion of public lands, will put exceptional pressure on the land managers of those ecosystems.

We offer a research opportunity that takes advantage of a variety of USGS resources ? ranging from existing datasets to large, on-going manipulation experiments ? to increase our understanding of climate controls over Colorado Plateau carbon cycling. The successful postdoctoral applicant will design a project that effectively gathers and synthesizes information to  elucidate connections between climate and carbon cycling on the Colorado Plateau, with the ultimate goal of informing predictions regarding future climate and carbon cycling. Within this overarching objective, the  postdoctoral researcher could focus on distinct system components
(e.g., plant responses to changing climate, soil responses, etc.) or their  linkages, could consider interactions between carbon cycling and other biogeochemical cycles, and can utilize the following unique USGS resources:

(1) Existing datasets of climate variation and manipulation, namely  long-term Colorado Plateau climate and plant variation datasets and a large soil respiration dataset from a previous temperature and moisture manipulation experiment;
(2) A large, on-going temperature and soil moisture manipulation study;
(3) Research in conjunction with existing biogeochemical studies using a natural climate gradient on the Colorado Plateau;
(4) Predictive modeling efforts to improve regional forecasting and land management efforts.

Applicants do not need to use all of the resources outlined, but could plan for a body of work that takes advantage of what they feel are the most  robust aspects of any of them. We recommend contacting one or more of the research advisors for additional information regarding the research  opportunity.

To Apply
Applicants should contact Sasha Reed screed@usgs.gov , or the other advisors listed above to express their interest.  Please include a CV. Depending on project needs and advisor approval, the postdoc could be located in Moab, UT; Boulder, CO; Denver, CO; Menlo Park, CA; or La Jolla, CA. [13 December 2009]

Position to be based in Hilo, Hawai'i; closing date: 10/30/09

For further information, please contact Creighton M. Litton (litton@hawaii.edu; phone: 808-956-6004)

A postdoctoral position is available immediately for a highly qualified individual to study the impacts of invasive species on ecosystem structure and function in tropical Hawaiian rainforests.  The successful applicant will work primarily on a project to examine the impacts of nonnative, feral pigs (Sus scrofa) on vegetation dynamics (native and nonnative biodiversity) and ecosystem processes (carbon and nitrogen cycling).  Depending on background and interest, work may also include the use of remote sensing techniques (LIDAR and hyperspectral remote sensing) to develop tools for identifying and mapping strawberry guava (Psidium cattleianum) invasion. Both projects include a significant field component in the Hawai'i Experimental Tropical Forest.  

Applicants should possess: (i) strong quantitative skills; (ii) potential for publishing in high quality journals; (iii) experience in plant ecology (vegetation dynamics) and ecosystem science (field measurements of carbon and nitrogen pools and fluxes). Experience with remote sensing techniques for characterizing forest structure and experience in Hawaiian or other tropical ecosystems are a plus but are not required.  The appointment is for 2 years with full benefits and a competitive salary (second year pending satisfactory performance).  The desired start date is January 2010, but is flexible.  

Please direct any questions regarding the position to Dr. Creighton M. Litton ( litton@hawaii.edu ) with "Invasive species postdoc" in the subject line. See http://www.ctahr.hawaii.edu/ LittonC/apply.html for detailed information on how to apply for the position via the Research Corporation of the University of Hawai'i (RCUH). Closing date is October 30, 2009.

Postdoctoral Position in Biogeochemistry/Soil Microbial Ecology, University of Toledo, Ohio
A postdoctoral position at The University of Toledo Department of Environmental Sciences is available to work on a project evaluating plant-soil-microbial interactions in arctic tundra ecosystems. The research goals include: 1) Varying the length and timing of the growing season in the field by advancing snow melt and warming the ecosystem; 2) Establishing the fine scale seasonal time-courses of soil N availability, plant N content, leaf expansion, root growth and rhizodeposition, ecosystem respiration, microbial biomass and enzyme activity; and 3) Conducting lab experiments to determine the extent to which microbial activity is limited by temperature, and C and N availability at different times in the growing season. The researcher hired for this position will work toward the completion of these project goals, and will have the opportunity to conduct his/her own original research associated with this project. These responsibilities will require the postdoctoral research associate to spend approximately three months at Toolik Field Station in northern Alaska from approximately May 15 ? August 15.  A PhD in soil/plant ecology or nitrogen biogeochemistry, experience studying soil nutrient dynamics and/or soil microbial ecology, and a demonstrated track record of publishing research results are required. This position will remain open until filled. Interested applicants should send a cover letter, CV, and list of references to: Michael Weintraub, michael.weintraub@utoledo.edu. For more information see http://www.eeescience.utoledo. edu/Faculty/weintraub/ opportunities.htm . or contact: Michael Weintraub by email or by phone: (419) 530-2585 [20 Oct 2009]

Project Description
The unprecedented melting of mountain glaciers and other ice features worldwide is altering hydrologic processes and exposing deglaciated surfaces to the earliest stages of ecosystem succession. Rapid change is occurring in alpine environments but there is limited understanding of the consequences of these changes for biogeochemical cycling and ecosystem health. One example of unexpected change is that mean annual stream nitrate concentrations have increased by 50% since 2000 in the Colorado Front Range, apparently as a result of warming-induced stimulation of N-fixation and nitrification in newly-exposed mineral sediments. Concurrent with increasing N export, there has been a significant increase in the discharge to precipitation ratio of water and increased dissolved concentrations of weathering products including calcium, sulfate, and silica. Because atmospheric N deposition in the area has not increased since 1999, we hypothesize that climate warming, which accelerates ice melt, is affecting headwater basin biogeochemical processes, possibly across the entire American West (excluding Alaska). Since high alpine waters are chronically oligotrophic, even very low inputs of additional nutrients stimulate algal productivity, transform algal species assemblages, and increase primary productivity. Consequently, high alpine waters may be undergoing significant and dramatic climate-induced biogeochemical changes.

Our research questions range from understanding the nature and rates of change in biogeochemical and microbial processes as mountain glaciers recede to understanding the broad biogeochemical implications of glacier retreat across the American West. The first requires intensive studies in one or more headwater sites, while the second requires development of methods that allow us to scale up with a level of confidence that goes beyond speculation. We seek a postdoctoral fellow who can contribute to one or more aspects of this study. We specifically seek expertise in glacial processes, microbial ecology, biogeochemistry, or hydrochemistry. The candidate will round out a team of ecologists, geographers, and graduate students. Within this interdisciplinary team there are many research avenues available to the candidate, including studies of: 1) the presence and rate of change of glaciers and other ice features across western US mountains; 2) the microbial community composition, function, and rates of microbial mineralization and nitrification in glacial landforms along a continuum of development from ice through sediments and permafrost to alpine soils; and 3) explorations of the sources, concentrations and chemical and isotopic composition of nitrogen, carbon, and weathering products in waters coming from different glacial landforms. The ideal candidate will be able to link one or more of these topics for elucidation of processes.

Candidates for this research project should have demonstrated expertise in one or more of the topics listed above. The successful candidate will also demonstrate his or her prior successful experience working as a member of an interdisciplinary team. Field work in extremely remote locations will be a necessary part of this study.
