After the extreme: Measuring and modeling impacts on terrestrial ecosystems when thresholds are exceeded
Place: Accademia dei Georgofili, Florence, Italy
Date: April 12-15, 2016
We invite applications from US-based graduate students and postdoctoral researchers to attend the workshop “After the extreme: Measuring and modeling impacts on terrestrial ecosystems when thresholds are exceeded” to be held in Florence, Italy 12-15th April 2016. The workshop is organized by the two international research networks, INTERFACE and CLIMMANI. Selected applicants will have their travel and lodging expenses reimbursed by INTERFACE. Meeting details are below. Please forward this message to potentially interested candidates.
To apply please submit a one-page CV that includes the name, email address, and phone number for your current dissertation or postdoctoral advisor, a short paragraph on why attending the meeting would enhance your career, a statement if you have received prior INTERFACE support, and a poster abstract to Aimeé Classen (firstname.lastname@example.org). The application needs to be a single PDF titled "Lastname_INTERFACE_Florence" and the subject line of the email should be the same. Application deadline is March 9, 2016. All students and postdocs will be REQUIRED to present a poster at the meeting.
INTERFACE is based in US and CLIMMANI in Europe, and both networks bring together researchers working on climate change effects in terrestrial ecosystems in order to facilitate interaction, syntheses of results and collaboration. In particular, facilitating interactions among experimentalists and ecosystem and earth system modelers has a special priority.
The international workshop in Florence 12-15th April 2016 is organized by Claus Beier, Aimee Classen and Klaus S Larsen, University of Copenhagen (DK), Jeff Dukes, Purdue University (US), Anke Jentsch from University of Bayreuth (DE) and Franco Miglietta, Institute for Biometeorology, National Research Council.
Extreme events – the topic
Ecosystem experimentation related to climate change has been carried on for several decades providing valuable information on ecosystem responses to increased atmospheric CO2 and temperatures and altered precipitation. Experiments have been carried out in a wide range of ecosystems and climatic conditions and for time ranges of years to decades. They include many single-factor experiments as well as a more limited number of multifactor experiments in which interactions among factors have been addressed. These experiments have generated significant knowledge about ecosystem responses to the main climatic stressors, have informed and tested models, and have built the foundation for major policy advice, e.g., in the IPCC assessment reports.
Common to these experiments is that they have in most cases been based on “most likely scenarios” or “average scenarios” and in cases where extreme weather conditions have been addressed, these extremes are mostly “moderately extreme”. This means that our knowledge about the harshest, most extreme conditions that surpass thresholds and tipping points is generally limited and mostly lacks experimental confirmation. Further, this means that ecosystem models also lack that knowledge and/or validation against measurements.
Therefore, the workshop in Florence will focus on “extreme extremes”. What is our current understanding of such events, and their corresponding thresholds and tipping points? How do thresholds differ across ecosystems and successional states? How do organisms and ecosystems respond and recover when thresholds are exceeded, and how will global changes affect the recovery trajectories? How have and can we address these questions experimentally and in models? What is our current understanding of plant and ecosystem responses to very extreme events and how do we close the gaps in knowledge from an experimental and modelling point of view?
The workshop will consist of 4 sessions that could be seen as a road map for identifying the gaps and the answers:
1. What is the current conceptual understanding of ecosystem responses to very extreme conditions and ecosystem recovery?
2. Long term ecosystem responses to climate change - what do current models tell us?
3. Interactions between climate change, disturbance regimes and successional stages – what does the experimental evidence tell us?
4. Impacts of extremes - how do we design future experiments and models to tackle the unknowns?
The meeting time will be split 50:50 between scientific presentations (incl. posters) and group discussions. This means that we specifically designed the workshop with ample time for discussions and interaction among participants. Talks will vary in length, with most talks being short and “statement-like” rather than long and comprehensive.
Breakout sessions: The group discussions will be organized in smaller breakout sessions with the goal of outlining a plan or a synthesis paper identifying key messages related to the overall topic. Each breakout group should ideally synthesize and discuss the state of knowledge within the area and identify gaps in knowledge and abilities to model it at a local and global scale. The breakout groups will be given sufficient time to discuss and condense their thoughts and outline a plan for developing a product after the end of the meeting. In order to organize the breakout sessions most efficiently and with the greatest relevance to the participants’ interests, we will ask all participants to share their views on the most urgent science questions and gaps in knowledge as part of the meeting registration process.
Poster session: The poster session will start with "flash talks," one-minute, one-slide talks to highlight each poster.
Field trip: The workshop will start on the 12th with an excursion in the area around Florence with both scientific and historical/cultural highlights.
Phosphorus Cycling in Terrestrial Ecosystems: Taking a new approach to advancing our fundamental understanding through a model-data connection
Place: Townsend, Tennessee, USA
Date: May 22-25, 2016
We invite applications from US-based graduate students and postdoctoral researchers to attend the workshop “Phosphorus Cycling in Terrestrial Ecosystems: Taking a new approach to advancing our fundamental understanding through a model-data connection” to be held in Townsend, Tennessee, from May 22-25, 2016. The workshop is sponsored by the US Department of Energy, the National Science Foundation, and the NSF-funded INTERFACE Research Coordination Network. Selected applicants will have their travel and lodging expenses reimbursed by INTERFACE. Meeting details are below.
To apply please submit the following items, consolodated into a single PDF file: 1) a one-page CV that includes the name, email address, and phone number for your current dissertation or postdoctoral advisor, 2) a short paragraph on why attending the meeting would enhance your career, 3) a statement if you have received prior INTERFACE support, and 4) a poster abstract. The PDF file must be named "Lastname_INTERFACE_Phosphorus" and emailed to Jeff Dukes (jsdukes AT purdue DOT edu). The subject line of the email must be the same as the file name. Application deadline is April 7, 2016. All students and postdocs will be REQUIRED to present a poster at the meeting.
Why hold a workshop on this topic? Phosphorus (P) has been shown to limit a number of fundamental processes in a wide range of ecosystems; however, despite its importance, most earth system models do not currently include any manner of the P cycle. This hinders the utility of these models for generating and testing hypotheses and for forecasting the effects of global change. Importantly, a critical challenge for P modeling efforts is also a critical challenge for the scientific community as a whole; namely, determining a way forward for improving our understanding of the key drivers, processes, and global change responses of the P cycle. Bringing together P experts would allow for the addressing of this need through: (1) a more synthetic understanding and conceptualization of P cycle dynamics, (2) the merging of varied P and associated data, (3) improved process-based modeling of the P cycle, and (4) P data-model integration. Another potential success stems from the power of explicit collaborations between empiricists who study P cycling and modelers considering the inclusion of P into models.
Participants will represent diverse theoretical, empirical, and numerical modeling perspectives that are critical for improving our understanding of the terrestrial P cycle in the context of global change. The meeting will include experts that span a variety of research perspectives and methods and is expected to have five outcomes: 1) an improved understanding of terrestrial P cycling from varied assessments; 2) synthesized datasets that will be publicly available for analysis and modeling; 3) a meeting report that will be submitted for publication in a peer-reviewed journal and a complementary set of data-based papers; 4) a set of plans for collaborative research project(s)/grant(s) to identify approaches likely to gain the knowledge necessary for improved understanding in critical areas; and 5) a network of individuals dedicated to fostering cross-disciplinary approaches to P research.
The organizing committee consists of Xiaojuan Yang (ORNL, USA), Rich Norby (ORNL, USA), Sasha Reed (USGS, USA), Jeff Dukes (Purdue University, USA), and Peter Thornton (ORNL, USA).
Student Collaborative Exchange Program
To further facilitate collaboration in the research community, INTERFACE plans to sponsor a limited number of “collaborative exchanges” for US-based graduate students, in which students who primarily work with models spend a brief period (up to one month) working in an experimental setting, or students who primarily work on global change experiments spend a brief period (up to one month) working in an ecosystem or Earth system modeling setting. These exchanges should ideally allow the student to continue working on a similar topic, but from a different perspective. Interested graduate students should identify a laboratory in which they would like to work, and should secure approvals from their advisor and the exchange lab’s PI. To apply, students should submit as a single PDF file: (1) a two-page proposal explicitly stating the questions being addressed and why the collaboration will facilitate answering them, (2) an NSF-style CV, (3) a one-page budget justification, and (4) letters of support from the advisor and the PI of the lab the student will visit. Applications should be sent to Aimée Classen <email@example.com>. Applications will be reviewed at two times each year, starting on the fourth Monday of April and the fourth Monday of October, through the end of 2016. Allowable expenses include airfare, meals while traveling to and from the exchange location, and housing. These funds cannot be used to cover classes at the host institution or student/ PI salary. Exchanges may be partially or fully sponsored by INTERFACE.
