Research interests:

The Department of Ecology was created in 1996 on the basis of the Abiotic Diseases Laboratory. We have a long tradition in studies of the effect of industrial pollution on tree biology and forest ecology. From mid-1960s various projects were conducted aiming at the identification of less sensitive to pollution species of woody plants. The studies were conducted in various polluted areas in Poland (Upper Silesia, Cracow Region, and Sudety Mountains) and near different major polluters (iron and copper smelters, nitrogen and phosphate fertilizer plants). On the basis of field studies and laboratory experiments lists of species, populations and clones suitable for polluted conditions were created and the physiological basis of differential response to pollution was investigated.

Currently our research works is largely focused on various aspects of environmental physiology, ecology, biogeography and genetics and of woody plants. We conduct studies designed to reveal how forest trees respond at the whole-plant physiological level to various abiotic (elevated atmospheric CO₂ concentrations, pollution, and temperature) and biotic factors (insects and pathogenic fungi).

Collaborative research

Our Department has well-established scientific cooperation with various institutions within Poland and abroad. Among others, we are involved in:

• Studies on biogeographic adaptation to temperature, photoperiod and CO₂ in boreal conifers

Peter B. Reich, Jacek Oleksyn, University of Minnesota, USA; Mark G. Tjoelker, Texas A&M University, USA

The coniferous forests of boreal regions may be particularly affected by global environmental change. Temperature, photoperiod and CO₂ levels may interact to profoundly influence the phenology (seasonal timing of development), net carbon exchange and growth of tree species. However, for any given tree species, populations from different regions may respond differently to global change. This possibility has been largely overlooked to date in scientific studies of vegetation response to global change. Thus, we do not understand how populations originating from diverse environments have adapted to climate, or whether diverse populations will respond similarly to altered temperature or CO₂ concentrations. We explored these issues in both laboratory and field experiments, using diverse seed sources of major boreal conifers: pine and spruce. We tested whether populations that are adapted to colder environments respond differently to altered temperature and CO₂ levels than those from warmer environments. Growth, phenology, and plant chemistry and physiology were assessed. Field studies involved plantations of older, mature jack pine populations of broad biogeographic origin at several sites across a broad climate gradient in central North America. Field measures included assessment of growth and rates of photosynthesis and respiration. This research examined the generality of patterns and mechanisms among boreal trees and increased our understanding of the role of biogeographic variation in vegetation response to potential global change.

• Linking leaf and root traits to ecosystem structure and function in a common garden study of 14 temperate tree species

Natural ecosystems are dynamic, not static. For instance, plants themselves alter properties of soils and ecosystems. Thus, the characteristics of different plant species influence important ecosystem functions such as soil fertility, soil development and plant productivity, and thus in part control ecosystem functioning. The specifics of these controls, however, are very poorly understood due to difficulties in separating effects of climate or soils from those of vegetation. To explore the way in which plants can influence their own environment, we will utilize a unique common-garden experiment of 32-year old monoculture stands with 14 temperate tree species in Siemianice, Poland. This is the only such experiment in the world. The proposed research will compare and contrast leaf and fine root traits and their effects on ecosystem by examining: above- and belowground tissue physiology, structure and productivity, litter decomposition and soil chemistry and development.
