  1. ECOLOGY A STUDY OF RELATIONSHIPS

  2. ECOLOGY • Studies the way organisms interact with their environment

  3. Ecologists are : • Wildlife biologists or • Conservation biologists

  4. ECOSYSTEM • A functional unit of a biome • A group of organisms that live together and interact with each other and their physical environment

  5. Ecosystems can be : Natural Man-Made • Badlands, S.D. • Amazon Rain Forest • Yellowstone N.P . • A farm • A city • An aquarium

  6. Badlands, S.D.

  7. The Amazon Rain Forest

  8. Yellowstone N.P.

  9. A Farm

  10. ACity

  11. An Aquarium

  12. HABITAT • A place in an ecosystem where an organism prefers to live • All its’ needs are met here • Ex: food, water, cover, living space

  13. WOODPECKERS DOWNEY HAIRY only 6 ½ inches up to 9 ½ inches Lives at edges, along roads lives in interior of forest Soft, dead wood hard dead wood

  14. WOODPECKERS

  15. http://www.youtube.com/watch?v=YeSIwdMgsM0 • Downey woodpecker • http://www.youtube.com/watch?v=DTxJt6ZoguM • Both woodpeckers • http://www.youtube.com/watch?v=epvA2rDmpNQ • Bluebirds • http://www.youtube.com/watch?v=WHSjghhbjI4 • Wood duck

  17. BLUEBIRDS Can’t make own cavity; prefer open areas near scattered trees; feed on insects on ground; once very common (1900)

  18. Decline of Bluebirds • Pesticides • Loss of habitat- fences now made of steel • More aggressive birds drove away- tree swallows and house wrens • Competition with non-native species- starlings and house sparrows

  19. WOOD DUCK • Also a cavity nester • Endangered by human activities

  20. LIMITING FACTORS • SPACE- need breeding territory • FOOD- predator/prey relationship • CLIMATE/WEATHER-severe vs. day to day • COVER- hiding spot • DISEASE- population density • HUMAN ACTIVITY-development • SHADE- layers of forest

  21. CARRYING CAPACITY • Number of individuals the environment can support
