Fundamentals Flashcards
experiment vs field study
experiment -> controlled conditions (one factor can be examined)
field study -> variety of factors
species extinction risk (%)
25%
definition ecosystem ecology
energy and matter fluxes
ecosystem services
Supporting (nutrient cycling, soil formation, …)
Provisioning (food, freshwater, wood, fuel, …)
Regulating (climatereg, foodreg, diseasereg, …)
Cultural (Aesthetic, spiritual, educational, …)
scientific approach
observation in nature quastion hypothesis prediction experiment (setup, data collection, comparing data with hypothesis) hypothesis rejection or confirmation redo hypothesis or additional testing
biggest threads
biodiversity loss, nitrogen cycling (eutrophication) -> watersources
time and space?
ecology is boundless!
ecologist therefore has to set boundaries in time adn space
abiotic
biotic
atmosphere, climate, soil, water
other organisms
understanding ecology
imperative to seeking solutions for environmental problems
biomass wild mammals decrease (%)
82%
ecology today (4 main topics)
- human population growth
- biological diversity
- sustainability
- global climate change
decline of ecosystems (%)
47%
why ecology?
climate change, biodiversity, illnesses (covid)
illness from animal to human
FACHBEGRIFF
spillover
effects enhancing other effects
feedback loops (covid -> greenhouse gas)
