1. Challenges for global assessment of nitrogen impacts to human and environments: Review of the INMS and contributions of the ILTERNitrogen (N) is an essential nutrient for all biota, but it becomes pollutant when exceeds critical level in the environments. A number of human activities such as energy use and food production have increased reactive N cycle in the environments caused various negative impacts to ecosystems and human health locally, regionally and globally.  This workshop aims to review the current progress for the N impacts assessment program for human and nature and to find a new research direction among the ILTER network. Participants will review the recent updates of the guidance document for the N-impacts assessment methodology that have been developed as a part of the Activity 1.2 of the Towards INMS (International Nitrogen Management System) project funded by UNEP/GEF and will provide comments and suggestions for their further revisions and upgrades of the guidance documents based on the previous findings and useful experiences in the ILTER studies. The workshop participant will also discuss to develop a new research agenda along with the N-impacts assessment methodology of the INMS (e.g., collection and synthesis of the exiting N dose-responses relationships based on various observations and experiments in the LTER sites) using the strength of the ILTER network that is global site network of long-term and in-situ research in various ecosystems across different regions. This workshop links to the ILTER Nitrogen Initiative operated by various N researchers in the ILTER network since last several years.This workshop links to the Activity 1.2 (Co-lead: Hideaki Shibata and Jill Baron) of the Towards INMS project (http://www.inms.international/) and the ILTER Nitrogen Initiative (PI: Hideaki Shibata). Target group: Advanced researchers working on nitrogen related research in various ecosystems and environments Contact person: Hideaki Shibata 2. Introduction to Monte Carlo Error PropagationMonte Carlo simulation is a powerful tool for propagating uncertainty in complex ecological calculations.  For example, estimating confidence in stream loads requires accounting for uncertainty in many sources: the height-discharge relationship, analytical chemistry, interpolation between concentration measurements, filling gaps in discharge and concentration, and catchment area. The distributions of uncertainty for each of these factors can be more easily carried through with numerical estimation by randomly sampling the errors than by analytical approaches to error propagation. For forest biomass and nutrient content, we must account for error in tree measurements, regression models, and tissue concentrations. This workshop will show how to use Monte Carlo to propagate uncertainty from multiple sources, using Excel and R. Participants should bring laptop computers and ecological data and calculations in need of uncertainty analysis (you can use ours if you don't have your own). At the end of the workshop, some participants will have documented the uncertainty in their result. All participants will understand the principles of Monte Carlo sampling and will have tools for implementing uncertainty analyses.What to bring: Participants should bring laptop computers and ecological data and calculations in need of uncertainty analysis (you can use ours if you don't have your own). Target group: Beginners. Requirements: familiarity with Excel or R Contact persons: Mark B. Green, Ruth D. Yanai, John L. Campbell 3. Operationalizing long-term social-ecological research: future perspectivesDrawing on the lessons of long-term projects on social-ecological systems (e.g. eLTER, Programme of Ecosystems Change and Society), we will examine which are the key features that lead to successful long-term social-ecological research. During the workshop, we will apply participatory techniques and the SWOT tool to explore the strengths, weaknesses, opportunities and threats of long-term social-ecological projects. Participants of the workshop will work in small groups of 4-5 people, in which we unravel the main challenges of this research and the main opportunities to move forward. Team dynamics will be also explored by selected participants in order to illustrate how these dynamics can impact the output of participatory methods in transdisciplinary work. The main outcome of the work in small teams will be finally presented to all the participants by applying the fishbowl conversation technique.What to bring: Own notebook Contact persons: Berta Martin-Lopez, Daniel Orenstein 4. Where does initiative end? Towards the circumnavigation of ecological communitiesLitter and soil organic matter decomposition represents one of the main biogeochemical processes and as such may serve as an intermodal link between the researches disciplines. Within the TeaComposition initiative we are collecting harmonized data on long-term litter decomposition process and their drivers globally both across terrestrial and aquatic ecosystems in order to understand long-term litter carbon turnover and its drivers under recent and predicted climate. This workshop will be used to discuss recent efforts as well as future perspectives of the initiative and subsequently to set necessary actions for their implementations. Participants will review available data collected within TeaComposition initiative as well as within other related initiatives and will provide suggestions for their further use /analyses, potential new research questions, application of biogeochemical models and data management. The workshop participants will also discuss how the initiative can be used for its implementation in underrepresented areas by simultaneously helping other networks to bridge their data gaps. The outcomes of this dialogs will be used to define new joint tasks based on the accomplishments of the TeaComposition initiative.This workshop is related to the recent activities and future perspectives within TeaComposition initiative (https://teacomposition.org/).What to bring: Participants are welcome to bring their laptops. Target group:1) Advanced researchers working on biogeochemical processes including data analysts, modellers & networkers2) Young researchers with inspiring ideas Contact person: Ika Djukic 5. Understanding socio-ecological transitions - a “landscape” of changesCurrently socio-ecological systems face unprecedented changes emerging from climate change, societal transitions, global markets, crossing of planetary boundaries with respect to nutrients, biodiversity etc. That leads to complex challenges (environmental, social) or nexus situations requiring different or even a wicked approach, not only inter- or transdisciplinary, but asking for a different level of understanding and involvement from different stakeholders. That means that the role of the scientist is enlarging or needs to be enlarged so that they can act as an enabling element that will allow the co-production of knowledge necessary for undertaking transition at multiple spatial and temporal scales. Our workshop is focused on bringing to the discussion cases of socio-ecological transitions from all over the world, defining the triggers and driving factors, as well as societal, economic and ecological consequences, clarifying the role of scientists and science in understanding the process, addressing the complex problems and deriving best practices and universal approaches in stakeholder collaboration. We aim at joint paper on what are the landscapes of transitions we experience nowadays, what challenge they impose in terms of environment management and what do they require from all the actors in order to achieve sustainability as defined by SDG. What to bring: Pens, papers, good mood, A4 picture reflecting own landscape of transitions will be helpful, but you can also draw it in the meantime Contact person: Kinga Krauze 6. Droughts and deluges: Defining and understanding their ecosystem impactsSince the 1990’s, climate scientists have forecasted a future of more frequent droughts and deluges as the hydrological cycle intensifies with climate change. Yet our understanding of the impacts of these precipitation extremes remains largely anecdotal, and we lack a foundational perspective of their role and consequences in ecosystems. This workshop will explore and synthesize knowledge of ecosystem responses to droughts and deluges from across the ILTER network and beyond. We will compile observations gleaned from long-term monitoring, as well as results from precipitation experiments focused on extremes. ILTER sites represent an untapped resource for advancing our understanding of these climate extremes, and an OSM workshop is an ideal venue to begin synthesizing knowledge and data from across the ILTER Network. The goals of the workshop will be 1) to present a comprehensive overview of definitions of droughts vs. deluges and their known effects, and 2) to strategize a plan for conducting synthesis research using ILTER network data to examine the impacts of droughts vs. deluges on ecosystem structure and function. In the process, we hope to answer a number of questions.  For example, does sensitivity to drought vs. deluges differ among ecosystem types? Do the legacies of periods of water scarcity differ from legacies of precipitation excess? Do the impacts of these precipitation extremes on biodiversity vary depending on the trophic level, ecosystem type or climate region, or particular species or functional groups examined? And are there are systematic differences in the effects of extreme but relatively short-term events (e.g. a period of no rain for a few months) vs. longer-term (maybe multi-year) periods of extremes? What to bring: Own notebook, 5 min summary presentation of drought/deluge research Contact person: Melinda D. Smith 7. Understanding and responding to extreme weather events in ecosystems and social-ecological-technological systems (SETS)The year 2017 was dubbed “The Year of Extreme Weather” (NPR 2017), with three major hurricanes making landfall in the United States, while drought prevailed and fires raged in California and the US Southwest. Worldwide in 2017, record heat and wildfires hit Chile, Spain, and Portugal, while South Asia was beset by unusually strong monsoon flooding. Unfortunately, this type of news is becoming ever more common. In the Anthropocene—characterized by ever-growing challenges from globalization, climate change, war, conflict, resource over-exploitation, and growth—people and ecosystems are experiencing extreme weather-related events of increasing magnitude with increasing frequency.  This changing landscape highlights an urgent need to bring clarity to understanding of extreme events and their impacts while also determining how best to respond to them. Extensive but non-intersecting literatures on disaster risk reduction, engineering resilience, social-ecological resilience, nature-based solutions (ecosystem-based adaptation), and ecological disturbance deal with extreme events, their impacts, and ecosystem or SETS responses. We aim to bring together social, ecological, and engineering perspectives on resilience with ecological perspectives on extreme events as they are represented among ILTER sites working on (or experiencing) disturbance, considering the following questions:• RQ1: What are the drivers of extreme events? Definitions, diverse disciplinary perspectives• RQ2: What are the outcomes of extreme events? What trade-offs (spatial, temporal, and among stakeholders) are likely and how are they resolved (or not)?• RQ3: How do we respond to extreme events? Coping, adapting, transformationAlthough we approach this from an urban perspective, we believe that urban and non-urban scholars can learn from each other in considering how to understand and promote resilience to extreme events. What to bring: Notebook, markers, ideas Target group: Those working in LTSER; relevant to the themes of (2) Climate change impact on ecosystem processes and (4) Advances in long-term socio-ecological research and sustainability science Contact persons: Nancy Grimm, David Iwaniec 8. Towards a Multilingual ILTER Vocabulary:  A Quality and Usability Evaluation Workshop on Translated TerminologyILTER vocabulary managers have initiated a colaboration with linguists from around the world to translate selected terms from EnvThes (http://vocabs.ceh.ac.uk/evn/tbl/envthes.evn), and the US LTER Controlled Vocabulary (https://vocab.lternet.edu/vocab/vocab/index.php) as the basis for developing an ILTER Controlled Vocabulary.  In this workshop, we invite ecology domain experts from China, Spain, Portugal, Brazil, Italy and Japan to join us to validate the quality of translated terms and definitions for the ILTER Multilingual Controlled Vocabulary.  We will begin the workshop with a brief overview of how the controlled vocabulary will be used in the ILTER Network, after which we will introduce a new ecological translation quality assessment tool (QAT) to validate the practical usability and quality of the translated terms and definitions.  Then, we will ask participants to fill in the survey evaluating the translations from English to their native language and making suggestions for improving them.  The contributions will be captured in the TopBraid software maintained by the Centre for Ecology and Hydrology (UK).  This vocabulary will be available for use by anyone in the environmental sciences, so your contributions may have impacts beyond the ILTER Network.In a broadly distributed network such as the ILTER Network, scientists need mechanisms to overcome the diversity of languages used to document data to discover and re-use the datasets. Development of a multilingual ILTER Network vocabulary would help lower this barrier to data integration and synthesis. Once this vocabulary is established and in use throughout the ILTER Network, discoverability of ILTER data will be vastly improved with new data browse and search tools that can be developed for meta data portals such as DEIMS-SDR (https://deims.org/) and data repositories. As a first step, around 300 terms that are common to both resources have been selected for translation by linguists with expertise in Chinese, Spanish, Portuguese, Italian and Japanese.  These translations of terms and their definitions are done by non-ecologists, and validation is needed by domain experts in the ecological sciences. What to bring: Please bring a laptop.  We will supply an assessment survey tool and Excel files with the English terms and definitions and their translations into Chinese, Portuguese, Spanish, Italian, and Japanese. Target group: Ecologists with an interest in enhancing data discovery in the ILTER Network Contact persons: Barbara Magagna, Kristin Vanderbilt 9. Building a Multilingual ILTER Vocabulary: A Translation WorkshopData has the potential to revolutionize ecological research, but only if it can be found and understood.  In an internationally distributed organization such as the ILTER Network, scientists need mechanisms to overcome the diversity of languages used to document datasets so that they can accurately search for datasets in ILTER data repositories. Development of a multilingual ILTER Network vocabulary would help lower this barrier to data discovery.  New search and browse software, based on the multilingual vocabulary, could be developed for DEIMS and other ILTER data repositories.  Researchers would then be able to search for data, and better understand them, in whatever language they choose.This project builds on the considerable work that has already been invested in EnvThes (http://vocabs.ceh.ac.uk/evn/tbl/envthes.evn), Europe LTER’s Thesaurus, and the US LTER’s Controlled Vocabulary (https://vocab.lternet.edu/vocab/vocab/index.php).  As a first step to creating the ILTER vocabulary, 100 terms and their definitions that are common to both vocabularies have been selected for translation. We wish to capitalize on having so many ecologists meeting together at the ILTER Open Science Meeting to obtain translations for these terms into as many languages as possible.In this three-hour workshop, we invite all ecologists from all ILTER member countries with a native language other than English to join us to help translate these 100 terms. We will begin the workshop with a brief overview of how the multilingual vocabulary will be used in the ILTER Network, after which we will introduce the methodology for translating terms and definitions. Then, we will ask participants to work individually or in groups to do the translations.  Your valuable contributions will be captured in the TopBraid software maintained by the Centre for Ecology and Hydrology (UK).  This vocabulary will be available for use by anyone in the environmental sciences, so your contributions may have impacts beyond the ILTER Network. What to bring: Please bring a laptop.  We will supply Excel files with the English terms and definitions. Target group: Ecologists with an interest in enhancing data discovery in the ILTER Network Contact persons: Kristin Vanderbilt, Barbara Magagna 10. Exploring long-term biodiversity data from ILTER sitesIn recent years there is an increasing recognition of the importance of long-term ecological data. This is in particular true for biodiversity as reports on severe species decline have increase significantly.ILTER sites harbor a wealth of long-term biodiversity data often accompanied by numerous in situ measurements of abiotic drivers. In recent years the number of publications that are making use of these long-term data significantly increased, however, we believe there are still many more options to further exploring these data.In this workshop we provide a briefly introduction into the ILTER long-term biodiversity (and accompanying abiotic) data and a rough overview on recent long-term biodiversity analyses. This will include some information on the outcome of a last year ILTER call for long-term biodiversity data.In the three hours workshop, we invite all participants to jointly develop new ideas on how to further exploit the long-term biodiversity treasure of ILTER and to discuss option for new joint papers and projects. Target group: Biodiversity researchers with an interest in further exploring ILTER biodiversity and in writing joined publications Contact persons: Peter Haase, Ingolf Kühn 11. Citizens for Long-Term Ecological ResearchThe ILTER funded Research initiative “Citizens for Long-Term Ecological Research“ is a follow-up activity of the TRAIL (TRAvelling through ecosystems and biodiversity: long-term ecological research for citizens) initiative. It aims at providing the opportunity to compare various dimensions of Citizen Science in ILTER, across a wide range of different cultural and socio-ecological contexts, as well as worldviews of science-society and man-nature interactions. CS, defined as the active involvement of non-professional scientists in research, is experiencing an upsurge of interest. It is one of the ways to make science accessible and interactive for a range of different audiences and, at the same time, empowering citizens to engage in ecological science can help scientists answer questions that would otherwise be impractical to investigate. This workshop is a first step towards a reflexive analysis on existing CS practices at ILTER sites, taking also into account its different aspects (scientific, pedagogical and ethical) across different Countries. During the workshop we will discuss and develop the main issues to be tackled to conduct a detailed and exhaustive study on existing CS practices and projects at ILTER networks. The main outputs of the workshop will be an exhaustive questionnaire on CS to be sent through ILTER, in order to make a survey of the existing activities, practices, and projects and on the different tools used for the curation of the observations. Following the workshop and the survey, the results of the questionnaire will be analysed first in a report and then in a scientific paper, where existing practices will be described and compared, evidencing the different views within the ILTER community. Target group: LTER researchers, experts in science communication and researchers involved in citizen science activities Contact person: Caterina Bergami
