Amazonian Amazonian ManateeManatee
•occurs exclusively in fresh water. It prefers blackwater lakes, oxbows, and lagoons with deep connections to large rivers and abundant aquatic vegetation
•ranges throughout the Amazon River Basin of northern South America. Its range sometimes has been said to include the Orinoco River Basin
•populations of the central Amazon Basin make an annual movement in July - August, when water levels begin to fall
•Some return to the main river channels when the rivers shrink in the dry season
![Page 21: The Pantanal By: Stephanie Gary, Autumn Carey, Jenni Scotti, Katy Marlor, and Morgann Dalby.](https://reader033.fdocuments.in/reader033/viewer/2022051619/56649d455503460f94a21e3d/html5/thumbnails/21.jpg)
•do most of their feeding during the wet season, when they eat new vegetation in seasonally flooded backwaters
•during the dry season (September - March), they congregate in the main river channels or in deep parts of larger lakes and may fast for weeks or months for lack of available food plants
•manatee's large fat reserves and low metabolic rate, only about 1/3 of the usual rate for most mammals, allow it to survive at this time
![Page 22: The Pantanal By: Stephanie Gary, Autumn Carey, Jenni Scotti, Katy Marlor, and Morgann Dalby.](https://reader033.fdocuments.in/reader033/viewer/2022051619/56649d455503460f94a21e3d/html5/thumbnails/22.jpg)
•Subsistence and commercial hunters have long hunted the Amazonian manatee
•Its populations continue to decline, mainly due to hunting
•Other threats include accidental drowning in commercial fishing nets and degradation of food supplies by soil erosion resulting from deforestation
![Page 23: The Pantanal By: Stephanie Gary, Autumn Carey, Jenni Scotti, Katy Marlor, and Morgann Dalby.](https://reader033.fdocuments.in/reader033/viewer/2022051619/56649d455503460f94a21e3d/html5/thumbnails/23.jpg)
Pink Dolphin or BotoPink Dolphin or Boto
•central Amazon basin, large changes in water levels affect the local distribution of botos
•significant increases in water level during the flood season leads to the inundation of large areas of forest
•Botos move out of the main river into channels and small lakes and then into the forest itself, swimming among the trees
•occurs throughout much of the Amazon and Orinoco watersheds, being found almost everywhere it can physically reach without venturing into marine waters
![Page 24: The Pantanal By: Stephanie Gary, Autumn Carey, Jenni Scotti, Katy Marlor, and Morgann Dalby.](https://reader033.fdocuments.in/reader033/viewer/2022051619/56649d455503460f94a21e3d/html5/thumbnails/24.jpg)
•The boto is vulnerable to human-induced habitat changes and suffers some incidental mortality in fisheries
•Threats include being accidentally caught in fisheries, hydroelectric development, deforestation, and pollution from agriculture, industry and mining
•There are 10 major dams at present in the Amazon basin, of which 8 have isolated boto populations upstream
•These dams have caused fragmentation of the pink dolphins
•Since the boto feeds on dozens of species of fish, they are isolated from fishing locations in part by the dams
•Dams suppress natural fluctuations in flow, temperature, and detritus loading, which provide optimal conditions for a large number of aquatic organisms

The annual CO2 release of each ecosystem. In 1983 and 1986 the rainforest releases CO2 into the biosphere. In 1988 and 1992, the rainforest
becomes more what it is naturally, a CO2 sink.

What needs to be done?
Deforestation• Agriculture
– Using smaller areas– Let the forest repair itself
• Logging– Low impact harvest techniques– Reduced impact logging– Long-term planning
![Page 34: The Pantanal By: Stephanie Gary, Autumn Carey, Jenni Scotti, Katy Marlor, and Morgann Dalby.](https://reader033.fdocuments.in/reader033/viewer/2022051619/56649d455503460f94a21e3d/html5/thumbnails/34.jpg)
• Gold mining• Less is more• Mercury
– Find other methods for mining gold
• Invasive species• Habitat
– Don’t create habitats invasive species can choke out the native one
» Example- abandoned graze lands
• If all goes well things can improve• Environment • Climate• People• world
