Pekka Niittynen

Pekka Niittynen serves as a Postdoctoral Researcher at the Department of Biological and Environmental Science within the Faculty of Mathematics and Science at the University of Jyväskylä. His work focuses on ecological dynamics in extreme environments, particularly Arctic and high-altitude ecosystems.

His research expertise spans Ecology, Environmental Science, Arctic Research, Plant-Fungal Interactions, Microclimate Modeling, and Biogeosciences. He investigates how abiotic factors shape species associations, nutrient cycling, and ecosystem responses to climate change, with emphasis on plant-soil-microbe interactions and microclimate drivers in polar regions.

Analysis of his 2023-2025 publications reveals consistent focus on Arctic/alpine systems, demonstrating expertise in plant-fungal symbiosis (e.g., altitude-driven association strength), greenhouse gas fluxes in tundra, microclimate variability in boreal forests, and bioclimatic mapping. Key methodological contributions include experimental validation of fungal-mediated plant growth at high elevations and practical frameworks for terrestrial microclimate research.

He actively participates in the Predictive Community Ecology Group, a collaborative research team led by Nerea Abrego and Otso Ovaskainen specializing in advanced statistical modeling of ecological communities.
