Peatland Ecology Working Group
We are an informal working group concerned with peatland ecology. We combine expertise in plant ecology/ecophysiology and soil biology in our research topics, allowing us to combine different approaches to gain a comprehensive understanding of peatland ecosystem functioning. The group brings together not only some members of the Department of Ecosystem Biology and the Department of Experimental Plant Biology, but also people from other institutions.
One of the directions of our research is to evaluate the impact of long-term drainage and revegetation on the functioning of different peatland types (bogs, fens, spruce mires) with a focus on vegetation, organic matter quality, nutrient transformations, microbial community composition, production and emissions of greenhouse gases. Monitoring the impact of hydrological revitalization on the restoration of basic ecosystem functions of peatlands aims to identify suitable ecological indicators to evaluate the revitalization success.
Another topic is how plants have adapted to the specific environment of peatlands and how they influence peatland development. Our focus is on Sphagnum, i.e. moss ecosystem engineers, which often have a determining influence on the process of peat deposition. Therefore, in addition to the ecology and physiology of peatland plants, we also focus on the biochemical properties of their dead biomass from which peat is formed.
We also focus on interactions in the soil–plant–atmosphere continuum in ecosystems with organic soils. We study plant biomass and nutrient allocation patterns, and the quantity and quality of plant inputs (litter, root exudates) to the soil. We thus link above- and belowground plant processes to understand how changing environmental and management conditions may impact the processes and functioning of these ecosystems.
We are involved mainly in research of peatlands in the Bohemian Forest mts., in cooperation with the Šumava National Park, but also with other institutions. Within the framework of international cooperation we have participated in research of peatlands in various European countries. Selected long-term monitored sites in Šumava are also part of the Global Peatland Microbiome Project.
