Presentation Transcript

  1. Ch. 40a Warm-Up • Name examples of biotic and abiotic factors in the environment surrounding LHS. • Which biomes can be found in Colorado? • Define the following terms (either on separate notecards or vocab list page): • population • community • ecosystem • biosphere

  2. Warm-Up – Generating Hypotheses • Question: What type of cleaner will kill the most germs? • Develop a hypothesis based on this question. Be sure to include: • Independent variable (IV) • Dependent variable (DV) • What will your control be? • What are some things that you will keep constant between test groups? • Vocab terms: biogeography, fixed action pattern, sign stimulus, kinesis, taxis, imprinting, migration

  3. Identify: What do I see on the graph?Interpret: What does the info on the graph mean?

  4. Chapter 40a An Introduction to Ecology and the Biosphere

  5. You Must Know • The role of abiotic factors in the formation of biomes. • Features of freshwater and marine biomes. • Major terrestrial biomes and their characteristics.

  6. Ecology: the scientific study of the interactions between organisms and the environment • The ecological study of species involves biotic and abiotic influences. • Biotic = living (organisms – behaviors & interactions between organisms) • Abiotic = nonliving (temp, water, salinity, sunlight, soil)

  7. Heirarchy • Organisms • Population: group of individuals of same species living in a particular geographic area • Community: group of populations of different species in an area • Ecosystem: community of organisms + physical factors • Landscape: mosaic of connected ecosystems • Biosphere: global ecosystem

  8. Climate: long-term prevailing weather conditions in a particular area • Climate = temperature + precipitation + sunlight + wind • Macroclimate vs. microclimate: • Macro: work at seasonal, regional or local level • Micro: small-scale environmental variation (eg. under a log) • Climate change: some species may not survive shifting ranges

  9. Global Climate Patterns:Sunlight intensity

  10. Global Climate Patterns:Air Circulation & Precipitation Patterns

  11. Global Climate Patterns:Ocean Currents

  12. Global Climate Patterns:Mountains affect rainfall

  13. Which side of the canyon has more plants? Why? Black Canyon of the Gunnison River

  14. Biomes: major types of ecosystems that occupy very broad geographic regions

  15. Figure 34.12 Figure 34.12 Figure 34.7C Climate, latitude, and elevation determine biomes

  16. Climograph: plot of annual mean temperature & precipitation in a particular region

  17. Tropical Forest

  18. Desert

  19. Savanna

  20. Chaparral

  21. Temperate Grassland

  22. Northern Coniferous Forest

  23. Temperate Broadleaf Forest

  24. Tundra

  25. Lakes

  26. Wetlands

  27. Streams & Rivers

  28. Estuaries

  29. Intertidal Zones

  30. Oceanic Pelagic Zone (Open Water)

  31. Coral Reefs

  32. Marine Benthic Zone

  33. Which biome do these graphs represent? Yakutsk, Russia (Tundra)

  34. Which biome do these graphs represent? Campa Pita, Belize (Rainforest)

  35. Biogeography: geographic distribution of species • Factors: • Dispersal – movement away from area of origin • Behavior – habitat selection • Biotic factors – other species, food resources, competition, pollinators, predators • Abiotic factors – temp, water, oxygen, salinity, sunlight, rocks & soil

  36. What factors may have influenced the distribution of this species?
