Louisiana Wetlands Biodiversity Excelsior College April 14, 2014 Abstract The Louisiana Wetlands are a unique ecosystem and quickly disappearing. An average of 34 square miles of South Louisiana land, mostly marsh, has disappeared each year for the past five decades, according to the U.S. Geological Survey (Tibbetts, 2006). As much as 80% of the nation’s coastal wetland loss in this time occurred in Louisiana. From 1932 to 2000, the state lost 1,900 square miles of land to the Gulf of Mexico. As the land disappears so do the species that inhabit it.
deep) off the coasts of the Gulf of Mexico all the way down to Brazil, in the Amazonian River Basins, around the islands of Cuba, Haiti and Puerto Rico, as well as along the central west and east coasts of Africa, up the Nile and down to Madagascar. The West Indian/Florida manatees currently inhabit the warm sub-tropical waters along the coast of Florida (as far north as the Carolinas and west along the coast of Louisiana and Texas). Though their range is quite large, manatees today exist in only a few small populations due to centuries of hunting them for meat and hides, coastal development and boating, and environmental changes. It is currently estimated that there are only about 2,200 manatees remaining in the US. They have no natural enemies except man and power boats which are responsible for most manatee deaths- (in 1990, 218 manatees or 12 % of the total population were killed by boats), though the red tide (toxins released from the bloom of dinoflagellates) of 1982 and1996 killed over 15% of the population.
Digital Imagining of Sitta caroolinesis in Southwest Fort Wayne, IN By Loren DeMien, Undergraduate student of Predental, University of Saint Francis, 2701 Spring Street, Fort Wayne, IN 46808. 20 November 2009 Abstract The digital imagining of birds took place at a resident’s house, where different species of birds were recorded. The Sitta carolinesis was one of species videotaped. The bird was visited the bird feeder 7 times for an average of 12.71 seconds. Introduction White-Breasted Nuthatches live in most of North America, southern part of Canada, and Central America.
They need to feed their chicks and the colonies are often a long way from the fishing grounds. Each chick needs about 42 kg of food from each parent.The entire breeding population of emperor penguins may consume as much as 1,500,000,000 kg (1,500,000 metric tons) of krill, 115,000,000 (115,000 metric tons) of fishes and 3,500,000 (3,500 metric tons) of squid each year. Method Of Collecting And Eating Food Penguins feed at sea. Most feeding occurs within 15.3 to 18.3 m (50-60 ft.) of the surface.
The cheetah has suffered from inbreeding, high infant mortality, loss of habitat, a reduction in its prey base, conflicts with livestock farming, and a reduced ability to survive in parks and reserves due to the presence of larger predators. 5. On what continent did the cheetah originate and how long ago? Through the dating of fossil remains, it appears that the cheetah originated in the United States of America in the present-day states of Nevada, Texas, and Wyoming. 6.
The populations are becoming so hard to find that fisheries are now catching the fish in estuaries, a place where the juveniles grow. There is also no ban on fishing them during certain seasons. This leads to the capture of pregnant females, and of juveniles. The population has declined so much that many fisheries have gone out of business. The reason I don’t think that the consumption from predators is why the population is declining so rapidly is the fact that these predators have been hunting these fish for hundreds of years.
Today, more than 30 million people live in the region and are dependent on the Amazon’s ecosystem for food and shelter. Farming in the Amazon causes deforestation and has many other environmental impacts, yet still a number of crops such as soy and coffee are cultivated there. Cattle ranches also exist. Soy Plantations Soybeans are an important crop all over the world, they are frost sensitive and the best growing conditions are, according to Encarta Encyclopedia Online, in a temperature between 20 and 30 degrees Celsius, like the Amazon. Commercial farmers produce the vast majority of soybean consumed in the world.
Threatened- EASTERN MASSASAUGA RATTLESNAKE Where in Canada did the rattlesnake live? Massasaugas rattlesnakes live in Ontario. During spring, Massasaugas use open shallow wetlands or shrub swamps. They can be found in crayfish towers or small animal burrows which are adjacent to drier upland open shrub forest sites. During summer, Massasaugas move upland to drier areas.
Marsh Arabs or ‘Ma’dan’ built homes known as ‘mudhif’ without nails, wood or glass in under three days, along with the land these houses are built on, it is made up of compacted mud and rushes (MessyNessy p.2-3). The Garden was a home for escaped slaves and serfs. This area of desert gives home to an oasis filled with reed-beds, water buffalo and 66 different bird species. Most birds migrate between Siberia and Africa by way of the wetlands. For about 5,000 years, back to the Sumerian ancestors there has been a huge wildlife sanctuary and refuge for the human Marsh Arab culture (Richardson p.1).
Wild pigs are generally active at dusk, dawn, and at night. Introduced to the continental United States in 1539, feral swine (Sus Scrofa) are rapidly becoming established throughout the country. It is estimated that wild breeding populations of feral swine are now present in at least 35 states. Feral swine are a combination of Eurasian wild boar and escaped/neglected domestic swine (Wild Boar). Of all members of the pig family, Sus scrofa occupies the largest range.
