LTER-related sessions at EGU 2020

You are invited to submit an abstract and/or attend LTER-related sessions at the EGU General Assembly 2020 in Vienna, Austria

The 2020 EGU General Assembly will take place in Vienna, Austria from 3-8 May 2020. There will be two LTER-related sessions:

  • BG2.23: 'Whole system approaches in addressing long-term changes in ecosystems'
  • BG2.24: 'Linking terrestrial and aquatic domains with long-term observations and experimentation'

The abstract submission deadline is 15 January 2020, 13:00 CET.

Details of the sessions and how to submit an abstract are below.

Whole system approaches in addressing long-term changes in ecosystems

Convened by Michael Mirtl, Jaana Bäck, Giorgio Matteucci and Daniel Orenstein

The development and functions of ecosystems and their responses to environmental drivers are inherently long-term processes that need to be studied along gradients in time and space. Global anthropogenic drivers of change interact with natural processes, causing uncertainties, tipping points and potential crises in system behaviour Further, most ecosystem services are strongly interlinked and require a multi- and transdisciplinary approach that allows for the simultaneous analysis of multiple processes and feedbacks. The sites and platforms of the long-term ecosystem, critical zone and socio-ecological research networks and research infrastructures (ILTER, eLTER) distributed around the globe offer a unique tool for this.

This session focuses on research performed at sites and platforms implementing a whole system approach. Emphasis will be on results presenting long-term changes and responses of ecosystem and socio-ecological processes to environmental drivers, as well as observations scaling up from sites to larger regions up to the continental level.

We welcome studies linking biodiversity loss, climate change, and other anthropogenic pressures to ecosystems. We encourage contributions using interdisciplinary and multidisciplinary approaches, addressing relationships among different ecosystem compartments (vegetation, soils, waters etc.) or between ecological and social systems, as well as transdisciplinary studies that incorporate diverse forms of knowledge beyond the scientific community.

Linking terrestrial and aquatic domains with long-term observations and experimentation

Convened by Jens C Nejstgaard, Jaana Bäck, Katharina Makower and Terhi Rasilo

Diverse ecosystem components are strongly linked both functionally and structurally in the landscape. However, different aquatic ecosystems and land ecosystems are often studied separately, although e.g. the fluxes of carbon, nitrogen and energy link these domains intimately together. This implies that the environmental drivers affecting one domain are easily reflected also in another. Considering the current extensive land use changes and climate change, integrated studies where aquatic and terrestrial ecosystems are studied in combination are urgently required.

This session focuses on research covering both aquatic and terrestrial domains, and especially addresses the changes imposed either by natural drivers or experimental manipulations. Specific emphasis is on research done at sites or platforms that are providing long-term, multidisciplinary data and combining that with experimentation.
