Keynotes, sessions and workshops

Anna-Liisa Laine: How human impact changes disease dynamics in natural ecosystems

Human impact on natural ecosystems is pervasive, resulting in habitat fragmentation and loss of biodiversity. In my talk I will describe how the epidemiological and evolutionary dynamics of host-pathogen interactions are influenced by this change, and how biodiversity loss changes community level regulation of disease in the wild. I will discuss the importance of high-resolution long-term data, and global datasets for answering these questions.

Chris Evans: Quantifying and mitigating peatland greenhouse gas emissions: From sites to national and global inventories, and then back again

Werner Kutsch: (How ICOS results are applied to large global topics?)

We have four sessions:

  • Scaling - how to use measurements for modeling at different scales (Tue)
  • Biodiversity links to ecosystem functioning (Tue)
  • Lateral element transport between boundaries and fluxes across boundaries (Thu)
  • Natural climate solutions (Thu)

 

Scaling - how to use measurements for modeling at different scales

Understanding ecosystem schemes on a large scale is important as climate change is a global phenomenon. Modelling is an essential part when integrating different measurements and inferring information brought by the measurements to regional and global scales, as well as estimating and predicting at various temporal dimensions. This theme focuses on modelling approaches which use various local scale measurements in estimation of ecosystem processes, carbon fluxes, atmospheric and hydrological transports. We invite presentations widely related to the topic, such as those using process-based, upscaling, statistical and inversion methods, to discuss the use of the measurements in modelling and model developments, and the techniques of synthesising those data.

 

Biodiversity links to ecosystem functioning

Biodiversity is currently declining at alarming rates. This encompasses all aspects of biodiversity, from the level of genetic diversity to species, functional diversity and ecosystems. Biodiversity underpins many ecosystem functions and services that society relies upon (including provisional services, regulating services and cultural services).  While changes in abiotic drivers affect biodiversity, species also shape ecosystems by modifying their abiotic environment, redistributing resources (energy and matter) and modifying species interactions. Hence, species underpin essential ecosystem functions, and thus, where such functions are exploited by human society, ecosystem services. Crucial in this respect is the need to maintain or even enhance ecosystem resilience. 

We invite presentations on how the different biodiversity aspects are linked to ecosystem functioning and services, and what kinds of data is (or should be made) available to improve our understanding on the mechanisms behind these complex interactions.

 

Lateral element transport between boundaries and fluxes across boundaries

Lateral land‐to‐water transport of elements plays an important role in the biogeochemistry of terrestrial and aquatic ecosystems. Fluxes across physical boundaries change the element concentrations in adjacent environments on different spatial scales. This theme will focus on the mechanisms that control the variation, magnitude and speciation of elements being transported across ecosystems, habitats or zones. The theme is inclusive to the emergent approaches and methodologies that highlight how global change may perturb these fluxes, and identify major knowledge gaps and key avenues for future research.

 

Nature climate solutions - ways forward to enhance land carbon sink and reduce adverse climate impacts of land use

There is growing international interest in better managing soils to enhance terrestrial carbon uptake and to increase soil organic carbon content to contribute to climate change mitigation. This theme focuses on methods and management options which could enhance C sequestration into terrestrial ecosystems. We also ask, what are the key areas and methods to reduce soil/ecosystem carbon losses. Along with C uptake it is important to assess other, possibly adverse climate impacts related to e.g. albedo change, other GHG’s or evapotranspiration. Furthermore, since soil organic carbon content cannot be easily measured, a key barrier to implementing programmes to increase soil organic carbon at large scale, is the need for credible and reliable measurement/monitoring, reporting and verification (MRV) platforms, both for national reporting and for emissions trading. We invite presentations broadly tied around the topic - both experimental and modelling contributions are welcome. 

There will be three parallel workshops on Wednesday.

  • Dynamic data and data linking
  • Stable Isotope Measurements
  • Integrated modelling

Dynamic data and data linking

The "Dynamic data and data linking - databases as  source of data from point of view of data management" -workshop session focuses on data citation in both publishing scientific data and referring to different kinds of data sources. It will include short introductory presentations followed by discussion on how to secure referring possibilities with different data types or structures when publishing data.

Integrated modelling

This workshops aims at promoting integration between the RIs. We will invite participants from each infra to present their views on the themes to be discussed:

  • Methods for upscaling site-specific results to regional applications in carbon modelling and ecosystem processes (e.g. combining models of lateral and vertical fluxes).
  • How does scale impact uncertainty estimates?
  • How best to utilize data for model development and application?

Format: 3 x 15 min presentations with 10 min discussions after each presentation, 30 min general discussion. Comments and questions collected in chat or on a discussion wall.

Convener: Maria Holmberg/SYKE

 

Stable Iso­tope Meas­ure­ments

In this workshop we will discuss available isotope measurement systems in ecosystem sciences in Finland. We will collect information about different applications of stable isotope techniques and the aim of the measurements. Further, we will highlight important findings from isotope measurements and brainstorm about possibilities to further develop the stable isotope measurement network in ecosystem sciences in Finland. The overall aim of the workshop is to strengthen collaboration between ICOS, eLTER and AnaEE networks and to encourage dialog across different disciplines, approaches (isotope and non-isotope) and institutions. The workshop will provide space for informal exchange and brainstorming between scientists involved.

Abstracts

Abstracts should be maximum one page long. You can include figures and links to the further information (if available). Please use this template and submit your abstract as pdf through the registration link.

    Guidelines for presentations:

    The idea of the presentations is to let the others know what you are working on. Focus on the overview and highlights!

    In orded to give space for many of us, the presentation time is strictly limited to 5 minutes.

    You can use a couple of slides to support your talk. One slide is enough, 5 slides is the absolute maximum. Consider using graphical formats rather than lots of texts.

    Please send you slides to the organisers very latest on 30 April. The slides will be shown centrally to allow smooth transision.
