Soil Biodiversity, Functions and Ecosystem Services WF-OB-SUSB

Lectures
1. What is soil? Soil forming factors. Soil as a habitat. Soil structure and soil biota. The role of soil organisms in the processes of soil formation and organic matter transformation. Comparison of the soil-forming processes in Iceland and Poland.
2. Diversity and distribution of soil organisms in Europe - in different ecosystems (natural and managed ecosystems) and different zones (e.g. temperate (Poland) and boreal (Iceland). Patterns of soil biodiversity.
3. Interactions between soil organisms and the soil itself. Epedaphic, hemiedaphic, euedaphic organisms. Geobionts, periodical geophiles, temporarily active geophiles. Adaptations to soil habitat.
4. Size classification of the soil organisms by body width. Macrofauna, meso- and microfauna and microorganisms – main groups, numbers, diversity and their role in the soil.
5. The importance of soil biodiversity. Ecosystem services (supplies, supporting, regulation) provided by soil biota: (decomposing plant and animal residues, transforming and recycling nutrients, storing and releasing water, maintenance of soil structure and fertility, provision of clean drinking water, sequestering and detoxifying organic toxicants, bioremediation of pollutants, pest and pathogen control, erosion control, mitigation of floods and droughts, regulation of atmospheric trace gases). The economic value of soil biodiversity.
6. Use of soil invertebrates in soil biodiversity assessment and as soil biological quality indices (monitoring of pollutant effects; evaluation of environmental impact of agricultural management practices; using soil invertebrates as bioindicators of urban soil quality). Parameters of soil animal communities used for soil quality evaluation.
7. Current threats to soil biodiversity: (contamination (chemicals), soil compaction and sealing, erosion, decline of organic matter, salinisation, landslides, deforestation, climate changes, agricultural practices (deep tillage, the use of chemical fertilisers and pesticides, the removal of crop residues), desertification, acidification).
8. Current threats to soil biodiversity in Poland and Iceland – a comparison. Discussing the research of the ForHot project (Iceland) as a case study on the impact of climate change on biodiversity and soil functioning. Discussing the ongoing expansion of the invasive species (Lupinus arcticus, arctic lupine) in Iceland and its impact on soil life and quality.
9. Management strategies for soil biodiversity restoration, conservation and sustainable production. Practices which tend to promote soil health and practices which tend to reduce soil health in Poland and Iceland. Discussing the research in the WetWood project (Iceland) as a case study to demonstrate the role of afforestation to limit or mitigate GHG emissions from drained peatlands.
Classes
1. Sampling methods (frequency of sampling, number and storage of samples). Quantitative and qualitative methods for assessing the abundance of soil animals (including nematodes, springtails, mites, earthworms, snails, etc.).
2. Methods for extraction of animals from soil, preservation of samples, microscopic preparations. Microscopy techniques, creating photographic documentation.
3. Laboratory experiments performed by students aimed to study: i) The influence of different practices on soil fauna and ii) The importance of soil microorganisms and soil fauna in decomposition process
4. Analysis of the abundance (density) of different groups of soil fauna in the two laboratory experiments. Diversity analysis of soil fauna in collected samples - species richness, ecological groups and sentinel species.
5. Summary and interpretation of obtained results – reports and presentations.
6. Discussion on the practical use of soil animals as bioindicators - possibilities and limitations.
