The main aim of the Northern LTSER-platform is to pool research activities and monitoring data of northernmost research stations of Finland under four long-term research themes related to socio-ecological changes in Northern nature and communities. The connective factors of the research in consortium level are on the one hand northerness both in national and international level and on the other hand information management and data-sharing in the changing settings of scientific collaboration and infrastructures. The main study objectives involved in the Northern LTSER-platform are: i) to study population dynamics and productivity of populations living in northern and peripheral conditions; ii) to assess the effects of global change on northern ecosystems, iii) to study importance of the environment and environmental changes to livelihoods and people's welfare, and iv) to study the complexity and support the practice of information management within long-term socio-ecological research collaboration.
