  1. Community Interactions BioH – Chapter 40

  2. Basic Ecology Terminology • Habitat • Community • Niche • Community Interactions • The physical, chemical and biotic features of where an organism is typically found • All species within a habitat that interact with each other – influenced by: • Abiotic conditions • Resource availability • Adaptive traits of organisms • Species to species interaction • Population size • The sum of all activities & relationships an organism engages in as it interact in the community.(The “role” that an organism plays) • Relationships between communities within habitat • Symbiotic - “living together” • Harmful relationships

  3. Community Interactions Complete the Community Interactions Video Questionnaire!

  4. Community Interactions Most relationships are NEUTRAL (no effect on either species)

  5. Community Interaction Mechanisms • Defense Mechanisms • Camouflage • Warning coloration • Mimicry • Moment-of-truth defenses

  6. Ecological Succession Primary succession = succession where no soil exists Pioneer species = the first living organisms to populate an area Secondary succession = succession to existing ecosystem after natural disaster

  7. Mt. St. Helens Before eruption – May 17, 1980 After eruption – May 18, 1980 Today

  8. Other succession examples Tuolumne Meadows - Yosemite

  9. Climax Communities Land Biomes Complete the Climax Communities Video Worksheet

  10. Climate Diagrams

  11. World-wide land biome climate maps

  12. Other Biomes • Mountain ranges • Polar ice caps (Greenland) Aquatic Biomes • Freshwater Ecosystems • Flowing water • Standing water • Freshwater wetland • Estuary • Marine ecosystems • Photic • Aphotic • Intertidal • Coastal • Open ocean

  13. Primary Productivity A measure of energy produced per area
