Dynamic Equilibrium of Ecosystems
  • Every creature has a purpose!
  • Everything that ABOUT the creature has a purpose
  • Every species has a niche

46
Nature has a way of keeping things balanced
47
Biodiversity
  • Biodiversity is the total variety of life on
    earth. It includes all genes, species and
    ecosystems and the ecological processes of which
    they are a part (Convention on Biodiversity,
    1992)

48
Ways to maintain biodiversity
  • Migration
  • Natural Disasters
  • Disease
  • Adaptation
  • Climate fluctuations
  • Name some more????
  • Conservation- human action

49
Migration
  • Why do birds migrate?
  • What happens to the migration patterns when
    climate changes?
  • Think about and write it down!!!

50
  • Short Distance Migrations Warmer temperatures
    may help birds that travel short distances. They
    are able to expand their ranges. For example, the
    Tufted Titmouse is found in more northern areas
    each year.
  • Long Distance Migrations Changing seasonal
    temperatures disrupt the timing of some birds.
    This is dangerous for birds that have especially
    long migration routes. If birds leave later and
    later each year, they risk not arriving at their
    destination in time.
  • Stop Migrating Some birds may stop migrating
    all together if winters become milder each year.
    These birds then face the danger of surprise cold
    periods.
  • Rising Sea Levels Higher sea levels from
    melting ice at poles are destroying wetlands
    around the world. Estuarine systems are being
    becoming more saline and food chains that support
    migratory birds get disrupted. Birds rely on
    wetlands for rest stops.
  • Expanding Deserts Some birds, especially those
    that migrate from Europe to Africa need to travel
    over large deserts. Deserts are becoming larger
    because of dryer climates. This means that birds
    face the risk of having to travel over larger
    areas before being able to find water, food, and
    rest.

51
Human Factor
  • Climate changes
  • Habitat destruction/fragmentation
  • Reduction of biodiversity
  • Empty nichesunbalanced
  • Introduction of non native species
  • Lack natural control factors
  • Conservation
  • National Forests
  • Endangered Species Act

52
Habitat destruction/fragmentationReduction of
biodiversityEmpty nichesunbalanced
53
Habitat fragmentation
  • Above and beyond habitat loss
  • Isolation reduced immigration, re-colonization
  • Edge effects

54
Nonnative species
  • Competitive
  • Large leaf area
  • Rapid growth rate
  • Often in dense stands
  • Strong reproductive pressure
  • Early maturity
  • Prolific seed production
  • Vegetative reproduction
  • Tolerant and adaptive
  • Rapid response to disturbance
  • Release from natural enemies
  • Hybrid vigor

55
Some species of particular concern to forest
management
56
Conservation
  • National Forests
  • Endangered Species Act
  • 2010 Photo Gallery

57
Natural Disasters
  • ABC News - Japan Earthquake before and after -
    Part 2
  • Name some Natural Disasters
  • Clears the land and helps to initiate succession.

58
Recap!
  • Ecosystems are sensitive.
  • Everything has a purpose.
  • All actions that are placed upon an ecosystem
    influence more then just that single aspect.
