  1. Ecological Consequences of Climate Change Miklós Kertész IEB HAS

  2. Goldewijk and Battjes (1997) U.S. Bureau of the Census Reid & Miller (1989) Global Change • Global-scale changes that affect the functioning of the Earth System • Much more than climate change • Socio-economic as well as biophysical • Human Population • Land Cover • Species Extinctions Features

  3. Distribution of forests – before major human impact

  4. Distribution of forests - present

  5. West European Heat Wave 2003 • 30% less primary production • 0.5 Gt carbon source • Delayed impact of forest crown damage • Oxygene depletion in deep lakes • Decline of mollusc species richness • Extensive wildfires • 5% of forests in Portugal, €1 billion

  6. Coral reefs • diversity hot-spot, high production, carbon sink • breeding habitat for pelagic fishes, crustaceans, and cnidaria • recreation value

  7. Decaying coral reefs • increase of temperature, dying of simbiont cyanobacteria • fishery • turism, collection

  8. Growing coral reefs

  9. 1950s and 60s: Import of South Africal Xenopus laevis to the developed countries for obtaining reagent for pregnancy test Atelopus, small tropical frogs From 1970s: Batrachochytrium dendrobatidis infection of tropical frogs in Central and South Americas, and Australia 2006: 70 Central and South Americal Atelopus species extinct out of 110-112 Climate effect

  10. South North Sessileoak + hornbeam beech Sessile oak Steppe +Dawny oak agriculture

  11. South North Sessileoak + hornbeam Beech ? Sessile oak Steppe +Dawny oak ?? agriculture

  12. Habitat change • Degradation • Specialist → Generalist • K-strategist → r-strategist • Species of → Species ofsmall distribution large distribution • Biological invasions • System collapse

  13. Distribution of forests – before major human impact

  14. Distribution of forests - present

  15. Provisioning services • • foods (including seafood and game) and spices • • precursors to pharmaceutical and industrial products • • energy (hydropower, biomass fuels) • Regulating services • • carbon sequestration and climate regulation • • waste decomposition and detoxification • • nutrient dispersal and cycling • Supporting services • • purification of water and air • • crop pollination and seed dispersal • • pest and disease control

  16. Cultural services • • cultural, intellectual and spiritual inspiration • • recreational experiences (including ecotourism) • • scientific discovery • Preserving services • • genetic and species diversity for future use • • accounting for uncertainty • • protection of options
