    Ecology - Tropical Rainforests Ecology - Tropical Rainforests Presentation Transcript

    • 1 PARES, Mariel SANTOS, Jemimah Joy
    • 2 February 5, 2012RainforestA dense evergreen forest with an annual rainfall of at least 406 centimeters (160 inches).

    • 35 February 5, 2012EcologyClimate, soil, carbon flux, forest succession
    • 36 February 5, 2012Climate “equatorial climate” (characterized by three major climatic parameters)  Temperature  Rainfall  Dry season intensity
    • 37 February 5, 2012Soils – Soil Types Classification of soils  Ultisols - well weathered, acidic red clay soils  Oxisols - acidic, old, typically reddish, highly weathered and leached
    • 38 February 5, 2012Soils – Nutrient Recycling How does nutrients in soils are recycled?
    • 39 February 5, 2012Soils – Buttress Roots create a wide spread root network at the surface for more efficient uptake of nutrients in a very nutrient poor and competitive environment.
    • 40 February 5, 2012Carbon Flux definedas the exchange of carbon dioxide between the atmosphere and a sink
    • 41 February 5, 2012Forest Succession an ecological process that changes the biotic community structure over time towards a more stable, diverse community structure after an initial disturbance to the community.

    • 73 February 5, 2012Biodiversity andSpeciationInterspecific competition hypothesis, Pleistocenerefugia
    • 74 February 5, 2012Interspecific CompetitionHypothesis because of the high density of species with similar niches in the tropics and limited resources available, they must do one of two things: become extinct or find a new niche.
    • 75 February 5, 2012Pleistocene RefugiaA theory developed by Jürgen Haffer in 1969 To further understand this theory, watch this video of
    • 76 February 5, 2012Human DimensionsHabitation, IndigenousPeople, Resources, Ecosystem Services, Tourism
    • 77 February 5, 2012Habitation Tropical rainforests are unable to support human life
    • 78 February 5, 2012 Indigenous People: Pygmy People hunter-gatherer groups living in equatorial rainforests characterized by their short height
    • 79 February 5, 2012ResourcesCultivated foods and spicesYam, Coffee, chocolate, banana, mango,papaya, macadamia, avocado, and sugarcane all originally came from tropicalrainforest and are still mostly grown onplantations in regions that were formerlyprimary forest.
    • 80 February 5, 2012Ecosystem Services Humankind benefits from a multitude of resources and processes that are supplied by natural ecosystems. e.g. Clean Drinking Water
    • 81 February 5, 2012Tourism anincrease in tourism has increased economic support, allowing more revenue to go into the protection of the habitat. e.g. Ecotours increasepublic appreciation of the environment and to spread awareness of environmental problems when it brings people into closer contact with the environment.

    • 83 February 5, 2012PAST and PRESENTThe rainforests before, how it were slowly gettingdestroyed, and ways to conserve it.
