Watery Wetlands





Now it is time for my final destination the completion to everlasting journey of environments. It’s watery wetlands time. I am visiting the Famous Florida’s freshwater marshes, they are well known because it is the single largest marsh system in the US, occupying almost 10,000 square kilometres. But a lot of the marsh has been taken away from development. The wetlands is filled with luscious vegitaion because it has a lot of tall reed plants, Typha and Phragmites grasses, Panicum and Cladium sedges, Cypress and Carex trees, Nymphea and Nelumbo floating aquatic plants. There are a lot of common invertebrates in this detrital ecosystem are true flies including midges, mosquitoes, and crane flies. Nematodes and enchytraceids are important decomposers in the system. Dominant mammal species include herbivores such as muskrats, shrews and mice. Waterfowl are distributed throughout the ecosystem along an elevation gradient, according to water adaptations. Abundant species include ducks, geese, swans, songbirds, swallows and black ducks. Although the shallow marshes do not support many fish, deeper marshes are home to many species, including northern pike and carp. This shows that it supports a lot of very interesting flora and furan. This may be the end for my journey but I think there are still some with journeys to complete.

Great Grasslands




Hi guys I just got to the huge savanna in Africa and it is hot but it is also very cold at night. The savanna has a hot and dry season. Savanna is grassland with scattered individual trees. Savannas of one sort or another cover almost half the surface of Africa and here is a picture of were I am. Because the savanna supports such a large number of species competing for living space, usually only one or a few kinds of grass are more successful than the others in a particular area. The are alot of fires in Savannas and they are most common in January the tip of the dry season. But funnyly enough it is vital for the biodiversity. In October, a series of violent thunderstorms, followed by a strong drying wind, signals the beginning of the dry season. Some of the larger grass can grow an inch or more in 24 hours. Different savannas support different grasses due to disparities in rainfall and soil conditions. The one I'm in is close to the coast and there are a lot of different life, plant and animal.




Next is my final

Now I am in the Andes a great mountain ridge that runs through the east side of South America. The land and natives to it are quite interesting like the fact that Incan tribes used to live here. I also found out that the climate in the Andes varies greatly depending on location, altitude, and proximity to the sea. The southern section is rainy and cool, the central Andes are dry. The northern Andes are typically rainy and warm. I am in the north part of them. The Andes range has many active volcanoes, including Cotopaxi, one of the highest active volcanoes in the world. What was particularly interesting was the fact that ancient peoples of the Andes such as the Incas have practiced irrigation techniques for over 6,000 years. And Because of the mountain slopes, terracing has been a common practice. Terracing, however, was only extensively employed after Incan imperial expansions to fuel their expanding realm.
