OIKOS Norway 2023 - The 6th conference of the Norwegian Ecological Society (OIKOS)

Conference: Ecology on a used planet

February 13-15, 2023, NMBU, Ås, Norway

Human land use and activities have altered ecosystems across the planet. Understanding the drivers and impacts of biodiversity loss and climate change is essential to ensure sustainable use of the Earth’s limited resources.

The main topic of this conference is the dilemma between the society’s adaptation to climate change, such as development of green energy and the land use required, and at the same time conserve nature and biodiversity.


There will be a quiz and social gathering on Monday evening.

We welcome all researchers, students, managers, policy-makers, government officials, members of the media, and anyone interested in ecology and the natural world.

Workshop descriptions

1) "Managing ecological data: Best practices for data sharing and data reuse based on transparent and reproducible workflows"

Lead: Organized by Aud Halbritter (University of Bergen) and Erlend B. Nilsen (Norwegian Institute for Nature Research and Nord University, and project leader of Living Norway Ecological Data Network)

Good data management is fundamental to high-quality research. Increasingly, universities, journals, and funding bodies demand open and reproducible research practices and data management across the scientific community.

Sharing and re-using data and FAIR principles are becoming the standard in ecology and improve the efficiency and quality of research and thus the credibility of science. Applying these practices however requires a set of data management skills.

In this workshop we will discuss what data management is and why it is important. We will show best practice in managing ecological data for sharing your own data, applying FAIR principles, and for reusing existing datasets. The workshop will also include hands-on training tools for sharing data and making reproducible documents.

The workshop is aimed at ecologists that create and/or reuse ecological data from early career researchers with little experience with data management to more experienced researchers. The hands-on training will be based on selected case studies, and implemented in statistical program R (with associated add-on packages).

Registration: Maximum number of participants is 30. Please register by sending an e-mail to oikos2023@nmbu.no. Mark the e-mail with "WORKSHOP Managing ecological data"

2) Scientist Rebellion networking workshop

The climate and biodiversity crises have accelerated to a point that demands urgent action from our societies. We scientists have a responsibility to step up to this challenge. Both the IPCC and IPBES reports paint a grim picture for the future: losses of biodiversity and whole ecosystems at scales only previously seen in mass extinctions; water and food insecurity; global threats to human health; and activation of tipping points pushing planetary systems past points of no return.

We know that the only way to guarantee a safe future — for ourselves, for our study organisms, and the rest of the natural world — is to act on this threat now, without any further delay. However, the actions needed to achieve this are not addressed and discussed in the scientific community enough, if at all.

In the Oikos Norway 2023 conference, we in Scientist Rebellion Norway want ​​to bring ecologists as well as other scientists together to discuss our responsibility in the ecological and climate crises, and how to take collective action to create the changes needed.

We will provide a brief introduction to Scientist Rebellion, after which we can discuss together how to push for change beyond just writing papers and documenting the destruction of ecosystems.

Registration: Join us in this informal networking workshop on February 13: sign up by emailing SRTrondheim@protonmail.com

3) In Norwegian: "Hvordan formidle økologi og økologisk forskning - til folk flest?" - FULL!

Lead: Anne Sverdrup-Thygeson, NMBU, Inger Auestad Sogndal, HVL

Vil du nå fram til flere med forskningen din? Velkommen til workshop i historiefortelling, for deg som gjerne vil formidle forskning populærvitenskapelig!

Beskrivelse: På workshopen vil vi jobbe med historiefortelling – hvordan du kan finne og forme det du vil si, til en fortelling som når fram til mottakeren. Vi skal snakke om metaforer, om faguttrykk, om forenkling, om overskrifter, om å skape bilder i hodet på leseren din, og om hvordan du kan utvikle et nært og engasjerende språk som folk forstår. Opplegget blir en mosaikk av korte forelesninger, oppgaver og diskusjoner, og vi legger til rette for erfaringsutveksling. Selv om workshopen tar utgangspunkt i skriftlig populærformidling, er poengene gyldige også for andre formater.

Du trenger ikke ha noen spesiell erfaring med formidlingsarbeid, men du må ha lyst til å prøve!

Tid: 10-16, med lunsjpause fra 12-12:30

Forarbeid: Alle deltakerne må, før de kommer, ha valgt ut et vitenskapelig arbeid (eget eller andres) som de har lyst til å formidle i populærform. Dette arbeidet skal du presentere (kort og uformelt, 1 minutt) som en del av den innledende presentasjonsrunden.

Registrering: Maksimum antall deltakere på denne workshopen er 15. WORKSHOPEN ER NÅ FULL. Vil du stå på venteliste? Send e-post til oikos2023@nmbu.no.

Keynote speakers

Richard Bischof

professor, NMBU

Richard is a wildlife ecologist, working at the Norwegian University of Life Sciences.

He and his team work on both applied and fundamental questions in ecology, with a special focus on developing methods that help us measure and understand processes that are difficult to observe directly. These include the spatial distribution and dynamics of elusive species such as large carnivores.

Richard is particularly interested in reconciling individual movements and fates with population-level phenomena.

Lena Gustafsson

professor emerita, SLU

Lena is a plant ecologist at the Swedish University of Agricultural Sciences.

Lena’s research is directed towards biodiversity and conservation in forests, especially in evaluating and developing of knowledge on effects and efficiency of conservation actions, and how such can be combined with forest management.

She is interested in processes and structures that drive species dynamics in natural as well as managed forests, and how such insights can be used in conservation strategies.

Ingemar Näslund

Water management strategist at the County administration of Jämtlands län

Fish biologist educated at the university of Umeå. Research within the field of fish migration, fish life history and fish habitat management. PhD 1991 at the Swedish University of Agricultural Sciences in Umeå.

Since 1999 at the County administration been dealing with most issues connected to water management; habitat restoration, fishery management, the Water framework directive, mitigation of hydropower effects on aquatic ecosystems, environmental monitoring and environmental objectives. Since 2013 responsible for applications for funding of restoration projects (LIFE, national funding, etc).

Eszter Kelemen

Eszter Kelemen

senior scientist, ESSRG

Eszter has a background in ecological economics and works at the Environmental Social Science Research Group, an independent nonprofit research organization based in Hungary.
Her main research focus is the socio-cultural and deliberative valuation of ecosystem services, which bridges across different disciplines, knowledge systems, as well as across science, policy and society. She was a coordinating lead author of the IPBES Values Assessment
She is especially interested in how the current social and institutional structures, which drive the environmental crisis, can be transformed for a more just and sustainable future.
