Two Ph.D. Positions in Forest Ecology
University of Life Sciences in Prague
We are seeking two highly motivated Ph.D. researchers to
join our team within the Forest Dynamics Lab of the
Department of Forest Ecology, Czech University of Life
Sciences in Prague, Czech Republic. Our current research is
focused on how disturbance regimes drive structural
variability, carbon dynamics, and biodiversity at stand and
landscape scales in primary mountain forests in central and
Despite the long history of land use, this region of Europe still has extensive remnants of primary mountain forests, particularly in the Carpathian and Dinaric mountain ranges. The large sub-continental region covered by the current research project includes the two dominant forest types in Europe, Norway spruce and mixed broad-leaf forests dominated by European beech. The aim of the current project is to quantify how disturbances influence forest structure, C dynamics, biodiversity and the multiple pathways of stand development that contribute to complex structure across these two forest types. Based on a unique set of established plots across several forest landscapes, detailed reconstructions of past disturbance histories will allow us to quantify spatio-temporal structural patterns and C dynamics along forest development pathways at stand, local, and landscape levels, as well as across environmental and climatic gradients.
The activities, together with our team, will include field work, laboratory processing of samples (mainly tree cores), statistically analyzing data, compiling results, and preparing peer-reviewed publications in international science journals. Two positions are available: 1) Forest Ecology Ph.D. - the first position will focus on reconstructing disturbance histories using tree ring data and examining links with current forest structure, composition, and indicators of biodiversity. This position will include field work; 2) Dendroecology Ph.D. - the second position will focus more on dendroecological analyses of existing tree ring data (current database of 20,000 tree cores from 1000 forest plots across the study region) to examine links between tree growth and abiotic and biotic factors. Although the candidate for the second position is not expected to participate in field-work, there will be opportunities to visit impressive locations of old-growth forests across the region.
We are a young and energetic research team with close collaborations with international partners. Opportunities exist for exchange visits and meetings. To obtain more information about our team, visit http://scholar.google.cz/citations?user=DaBJTM4AAAAJ

PhD Assistantship in Riparian Forest Ecology and
State University of New York-ESF
Project description: Linking basin-scale, stand-level, and individual tree water stress indicators for groundwater-dependent riparian forests in multiple-use river basins
Managing water resources is increasingly challenging in many river basins globally as the climate becomes warmer and drier. Human demand on water resources, particularly groundwater, is high in multiple-use river basins where significant withdrawals occur for intensive agriculture and industry. The interaction between high groundwater extraction by humans and climatic drought, such as that which is currently affecting large areas of California, can result in rapidly declining water tables with strongly negative consequences for groundwater-dependent ecosystems (GDEs). Riparian forests, which are hotspots of biodiversity and support key functions and habitats within many GDEs, are particularly sensitive to water table dynamics. Rapid and sustained declines in groundwater tables typically induce reduced growth, vigor, and physiological function in drought-intolerant riparian trees. These conditions, if they persist, lead to riparian forest decline, with substantial risks to the ecosystems they support and the services they provide to society. This NSF-funded project will use a suite of interdisciplinary methods to measure water stress in riparian forests that are linked to changes in groundwater availability. The study will take place in the Santa Clara River basin in Southern California, where as in many water-limited regions of the world, interactions between climate and water withdrawals for agriculture threaten the integrity of GDEs and their component species. The interdisciplinary project team from SUNY-ESF and UC Santa Barbara will couple high-resolution remote sensing with field-based tree-ring research and groundwater well data to develop water stress indicators across a range of geographic scales from individual trees to forest stands to an entire riparian corridor. The ultimate goal of the project is to identify trends and thresholds in forest response to groundwater decline that can be used to develop sustainable groundwater management approaches for protecting GDEs in multiple-use river basins.
The PhD position and how to apply:
We seek a Ph.D. student at the State University of New York College of Environmental Science and Forestry (SUNY-ESF) working with Dr. John Stella and interdisciplinary collaborators at UC Santa Barbara and The Nature Conservancy. The position will start in summer 2017. Research questions will focus on riparian ecosystem response to drought and methods will include field sampling to inventory riparian forest structure and health, collecting and analyzing tree rings for growth trends and annual water use efficiency using carbon isotopes, and assessing critical thresholds for riparian forest decline. Field studies will occur in the Santa Clara River basin in Southern California with lab work at SUNY-ESF and at the University of Utah. Ideal candidates will have an MS in ecology, environmental science, or a related field; a strong quantitative and statistical background; the ability to work in remote field settings; and interest in riparian forest ecology and tree ecophysiology in dryland regions. The position is funded for a minimum of three years and provides a competitive stipend, tuition and benefits. Interested candidates should send a CV/resume (with GPA and GRE scores), a description of research interests and experience, and names and contact information for 3 references to firstname.lastname@example.org.

University of Greifswald,
"BaltRap - The Baltic Sea and its Southern Lowlands: Proxy-Environment interactions in times of rapid changes" is a newly funded joint research network (see http://www.io-warnemuende.de/projekt/167/baltrap.html). Its focus is the coupled marine-terrestrial system of the Baltic Sea and its southern lowlands, which is highly sensitive to both natural climate forcing and human impact. To comprehensively understand the impact of rapid climate change in the southern Baltic Sea region (SBSR) and to distinguish between natural and human forcing, our BaltRap network aims, for the first time, at integrating high-resolution marine (sediments) and terrestrial (lake sediments and tree rings) proxy archives.
Within the interdisciplinary project the major task of the working group Greifswald will be to derive high quality intra-interannual proxy data (ring parameters: width, density, chemistry, anatomy) from a regional network of tree sites and species around the Baltic Sea basin. The inclusion of archeological/subfossil samples is planned as well. By linking these data to other proxies (e.g. marine and lake sediments, part of BaltRap) and calibrating them against instrumental climate and other monitoring data, statistically verifiable high resolution reconstructions of climate and landscape evolution for the research area will be developed with the special focus of understanding the varying anthropogenic influence over time.
We are looking for highly motivated and team-oriented candidates with a strong background in forest ecology and/or Dendrochronology who have a M.Sc. or Diploma degree in biology, geography, forestry, landscape ecology, or related disciplines. Applications of candidates holding a Ph.D. are welcome.

Czech University of Life Sciences in Prague, Faculty of Forestry and Wood Sciences
We are seeking a postdoctoral researcher to join our team within the Forest Dynamics Lab of the Department of Forest Ecology, Faculty of Forestry and Wood Sciences in Prague, Czech Republic. The project is titled “Disturbance regimes as drivers of structural variability, carbon dynamics and biodiversity at the stand and landscape levels in primary mountain forests in central and eastern Europe.”
Disturbance plays a dominant role in shaping the structure and function of forest ecosystems, but quantification of disturbance effects is typically limited by missing information on a location’s history and a region’s disturbance regime. Our lab uses tree-ring data to reconstruct site histories, providing insight into how forest characteristics recover from disturbances of variable severity. We are particularly interested in linking patterns in the severity and frequencies of disturbance to variation in tree size structure, carbon dynamics and biodiversity.
The successful candidate will have access to a completed database of 20,000 tree cores collected from 1000 forest plots distributed throughout remaining patches of old-growth forest is central and eastern Europe. Plots are distributed in a hierarchical design (i.e. plots nested within stands, within landscapes throughout the Carpathian mountain range). The aim of the design is to partition the effects of disturbance effects at a variety of scales, from local variation among neighboring locations due to smaller-scale gap dynamics to more extreme events impacting entire landscapes.
The selected candidate will be expected to lead projects using available tree-ring data to link tree growth and biomass dynamics to abiotic and biotic factors. Responsibilities will predominantly be data analysis and manuscript preparation. Opportunities to visit some of our impressive field locations will be available, but the candidate is not expected to participate in data collection.
We are a young and energetic research team with close collaborations with international partners. Opportunities exist for international exchange visits and meetings. To obtain more information about our team, visit http://scholar.google.cz/citations?user=DaBJTM4AAAAJ.
Applicants should have a PhD (at the time of hire) in environmental or related sciences (biology, ecology, geography, forest sciences), and excellent English communication and writing skills on the level of native speaker is essential.
Salary: 1300 – 1600 EUR based on the previous experience and performance We offer a 2-year position starting as soon as possible. The starting monthly salary will be around 1300-1600 Euro, which represents double of the median salary in the Czech Republic. To compare living costs see here: https://www.expatistan.com/cost-of-living In addition, there is a share increase based on the personal performance.

PhD Opportunity in dendrochronology
Québec en Abitibi-Témiscamingue
Effect of species mixing on long-term trends in forest productivity
Although a large body of recent research has already pointed to possible effects of a changing climate on tree growth across the boreal forest, there is still a need for better empirical data to verify some of the most fundamental assumptions adopted in this research. Climate impact studies have revealed changes in growth rates and the extent of forest decline as a result of increased evapotranspiration demand, variability in the frequency of extreme climatic and disturbance events (such as fires, insect outbreaks), and indirect effects of climate change, involving tree regeneration and competitive interactions within community. However, a vast majority of these studies has relied on a combination of short-term observations and long-term model-driven projections involving many not-so-evident assumptions. To address this knowledge gap we will conduct a study looking specifically at long-term changes in growth rates in natural pure and mixed stands of boreal Quebec. We will consider low frequency (century long) trends in growth as integral metrics of climatically-driven changes in growing conditions.
We are looking for an ambitious and highly motivated PhD student with a completed master degree in forest ecology, climatology, geography, ecosystem modelling, or mathematics. Documented experiences in dendrochronology, GIS-added analyses, work with large relational databases, modeling of biological systems and good skills in computer programming (R) will all be valued during the evaluation process. It is important that the candidate is fluent in English and has an excellent ability to formulate himself/herself both orally and in writing. Knowledge of French is an strong asset.
A past record of scientific publication and presentation is highly valued. We put great emphasis on personal characteristics of the successful applicant, solid work ethic, and in particular - the ability to independently manage a large volume of fieldwork and laboratory tasks, and meet reporting and publication deadlines.
The successful candidate will join a dynamic and international team of the Forest Research Institute at the University of Quebec at Abitibi-Temiscamigue, Quebec Canada (Igor Drobyshev and Yves Bergeron). The position is offered within the framework of a three-year MITACS project Can tree species mixing improve resilience and productivity of boreal forests?, in cooperation with consortium OURANOS and Ministère de l'Énergie et des Ressources naturelles of Quebec (Daniel Houle). It is expected that this 3-year PhD project will start in the January-February 2017. Please direct all inquiries to firstname.lastname@example.org and email@example.com
PhD position in Dendroclimatology
The Center for Dendrochronology at the University of
Minnesota is accepting applications for a fully-funded PhD
position to start in Fall 2017. The successful candidate
will join a NSF-sponsored project studying low-frequency
climate variability and the causes of widespread megadrought
in North America (http://www.nsf.gov/awardsearch/showAward?AWD_ID=1602512&HistoricalAwards=false),
and collaborate with paleoclimatologists, statisticians, and
climate scientists at the University of Minnesota, Cornell
University, and the United States Geological Survey (USGS).
Under the supervision of Dr. Scott St. George (http://umn.edu/~stgeorge), the candidate will use tree-ring data, climate simulations, and biological process models to clarify how and why drought in North America may persist for one or more decades. First, the student will produce a new set of tree-ring records from the Northern Hemisphere that is optimized to recover low-frequency (decadal- to centennial-scale) environmental signals. Afterwards, the student will estimate the spatial structure of dec-cen variability in tree-ring records across North America, and outline the fingerprint of major low-frequency climate modes within the tree-ring network. Other major tasks include (i) helping to lead a pair of summer workshops on dendroclimatology for statisticians and computer scientists, and (ii) collaborating with researchers at Cornell’s Emergent Climate Risk Lab (http://ecrl.eas.cornell.edu) to test the ability of state-of-the-art climate models to simulate megadrought.
Understanding decadal drought and multidecadal megadrought risk requires us to characterize the amplitudes and spatial patterns of climate fluctuations on these time scales. Decadal-centennial (dec-cen) variability in terrestrial climate, including ’megadroughts’, may arise due to low-frequency behavior in the oceans or may be residuals from high-frequency forcings, but instrumental climate records by themselves are not adequate to distinguish between these two frameworks. Proxy records from natural archives are able to extend our perspective on the climate system beyond the last century and a half, making these data essential for evaluating the pre-instrumental behavior of dec-cen climate variability. In terrestrial settings, records of tree-ring width and latewood density have been the dominant source of information about dec-cen behavior due to their high resolution and dating accuracy, but important questions about the ability of this archive to describe low-frequency climate variability remain unanswered.
We seek to hire a highly motivated student who holds an M.Sc. or equivalent in a relevant field and has research experience in dendrochronology, climatology, or Quaternary environmental change. Undergraduate or graduate training in botany, physics, statistics, or mathematics would be an asset, as would basic programming skills in Matlab, Python, R, or equivalent. Minimum academic qualifications include a 3.5 GPA on a 4.0 system.
$17,500 to $22,500 during the Fall/Spring academic term, depending on qualifications. Students will receive an additional stipend for summer work (up to $7,000), and be encouraged to apply for college- and university-level fellowships and research grants. Finally, if the successful applicant is a United States citizen, they will have the opportunity to apply for a USGS internship through their Graduate Student Preparedness program (https://powellcenter.usgs.gov/national-science-foundation-graduate-research-internship-program-grip).
How to apply
Students interested in this opportunity should contact Dr. St. George by sending an inquiry to firstname.lastname@example.org. In order to evaluate your qualifications, it would be helpful to share: (i) a cover letter outlining your research experience and motivation for joining this project; (ii) an up-to-date curriculum vitae, including contact information for at least two referees; and (iii) academic transcripts for degrees completed or in-progress (either official or unofficial).
Students will subsequently apply to either the Ph.D. program in Geography (http://cla.umn.edu/geography/graduate) or Land and Atmospheric Science (http://www.laas.umn.edu) at the University of Minnesota. Please do not submit an application to either program without contacting Dr. St. George first.
