Content of the Course
LANDSCAPE AND DIVERSITY
1. Landscape ecology: an introduction (Bunce, Jongman 1993)
1.1. Definition, history, concepts.
1.2. Sustainability: capacity of the earth to maintain and support life and to persist as a system.
1.3. Hierarchy: different levels involving complexes of different elements.
1.4. Gradients: gradual changes (in time) and ecotones (in space).
1.5.Diversity (Mansvelt 1997) - the basic concept in the management of landscapes. Habitat diversity as a criterion for landscape value.
2. Landscape as an ecosystem (Doing 1997). Landscape as a complex of geographically, functionally and historically interrelated ecosystems.
2.1. Mapping - geomorphology of the landscapes, vegetation patterns, soil diversity, hydrological conditions; patterns of soil , meso- and microclimate and animal communities as equally important landscape components.
2.2. Functional relationships - the basis of the ecosystem concept. Subsystems - biomass, nutrient cycles, energy levels and pathways, trophic levels, relationships between diversity and stability. Homogeneous and heterogeneous systems.
2.3. Man as a factor in the functioning of landscapes. Succession of ecosystems, human influence - more "openness" of landscapes, relatively greater dependence on abiotic conditions; human impact as increasing in- and outputs.
2.4. Ecological dynamics of landscapes (Gilpin et al 1992)
2.4.1. Global climate changes (Gall, Staton 1992)
2.4.2. Agriculture – the dominant interface between human beings and nature;
2.4.3. Biological diversity – the goal of conservation.
2.5. BIOLOGICAL DIVERSITY:definition (Biotic diversity in..., 1992; Biodiversity and ..., 1993; Biodiversity and Ecosystem..., 1993);
dynamical character of living diversity; importance of biodiversity (Gilpin et al 1992).
2.5.1. Levels of biodiversity.
2.5.2. Genetic diversity - variation of genes within species. Genetic diversity and maintaining of the populations (Fischer, Schmid 1998). Genetic diversity in forest (Behm 1998; Konnert 1998). Genetic diversity and environmental protection (Bender 1998).
2.5.3. Species diversity - variety of species. Measurements of biodiversity: species richness, species abundance, taxonomic or phylogenetic diversity.
2.5.4. Ecosystem diversity - the differences between ecosystem types; the diversity of habitats and ecological processes occurring within each ecosystem type. Relationships between the diversities of different components of ecosystem (above-ground/below-ground, plants/soil biota, etc) (Vandermeer et al 1998).
2.5.5. Alpha-, beta-, gamma- level of biodiversity (Gilpin et al 1992)
2.5.6. The biosphere – the environment for life on earth (Gilpin et al 1992).
2.6. Management problems at different levels:
- migration and dispersal, small populations, exploitation stress, dependency, human scales and human responses.
2.7. The factors having the influence on biodiversity: resources, geochemistry, geographical aspect, changes in time and space. (Biodiversity and Ecosystem Function, 1993).
2.8. The value of biodiversity.
2.8.1. The value of biodiversities´ components: ecosystem services (water, soil, nutrients, pollution breakdown, climate stability, maintenance of ecosystems); biological resources (food, medicinal resources, wood products, breeding stocks, population reservoirs, future resources), social benefits (recreation, cultural values, benefits of timely actions).
2.8.2. The value of diversity for ecosystems and organisms, social and cultural value
2.9. The conservation of biodiversity (Biotic diversity in... , 1992)
2.9.2 Conservation of genetic resources (Plucknett, Horne 1992; Woodruff, Gall 1992)
2.9.3. Management strategies (Orians, Millar 1992)
2.10. The monitoring of biodiversity (by Goldsmith, ed, 1993): why monitor, design of strategies, methods, selecting the criteria, timing, samples, integrated monitoring, indicators (Foissner 1997).
