Brazilian Atlantic Forest

The Brazilian Rainforest is one of the most unique, vast, and diverse regions of the world. To get a general idea of the diversity of the Rainforest, it makes up a total of one-third of the world forests (more than four million square kilometers), it contains half of the total number of named species in the world (eighty-thousand plant species, 1,500 fish species, and one-forth of the 8,600 bird species), and is the world largest holder of genes (Library 138-139). To say the least, the Brazilian Rainforest is one of the most important natural resources we, as humans, know. It would seem that this knowledge, alone, would also make the Brazilian Rainforest one of the most protected land areas on Earth as well. However, the situation is

The Interdependence of plants, animals, and humans is integral in the Amazon Rainforest ecosystem of the tropical rainforest biome. The key features of the Amazon Rainforest is the Amazon River. The Amazon Rainforest goes through Brazil, Peru, Colombia, and many other countries. Colombia has 10%, Brazil has 60%, and Peru has 13%. 80-90 degrees during the day and 50 degrees at night is the temperature of the Amazon Rainforest. There are dry and wet seasons. it gets 9 to 10 feet of rain a year. The terrain is in the Amazon Rainforest are rocky mountains, wetlands , plains, valleys, rivers, streams, and highlands. The dirt is poor with very few nutrients and it is very muddy. It is also dense with trees and rotting logs. The thin topsoils, made of decaying vegetable and animal parts, take up all the nutrients. In the Amazon Rainforest there 's the Congo River, the Rio Negro, and the Amazon River.

One of the biome which I found interesting was the Amazon rainforest. The Amazon Rainforest is region which is owned by more than 1 country because of its land mass. It is actually owned by 9 nations. This biome is situated in the amazon basin of South Africa. The Amazon Rainforest covers 5,500,000 km2 (2,123,562 sq mi) of total 7000000 km2 of the Amazon basin. This particular rainforest cover more than 50% of the world rainforest biome. So as to understand this particular rainforest biome better, I am going to talk about the Brazil part of the rainforest as it owns 60% of the rainforest. I found this particular

One can encounter every environmental extreme imaginable, from the intensely vertical terrain of the Andes, soaring up to altitudes of 5,000 meters (16,404 ft.) above sea level, to dry, low-lying lands along the western coast of South America. The climate zones are equally diverse, with some areas that are constantly hot and humid to others with subfreezing temperatures year round. Also within its boundaries are some of the driest places on earth- Chile’s Atacama Desert- to some of the most lush- the Amazonian rain forest to the east of the Andes- with rainy season lasting 11 months of the year.

The group discovered is more closely related to anteaters than to the other sloths (Document B). Though all of the groups (populations A-D and the anteaters), trace back to one common point, the newly discovered population of sloths is closer to anteaters than it is to the other three populations of sloths. This difference even is evident on the genetic level. The team geologist recorded that the new population shares “little to no common genes with other populations” of sloths in the region (Document E). Therefore, the new group is not closely related to the preexisting

As we enter this session all about travel, I decided to pick a book that was related. I chose to pitch this book because, first it will help me on the quest, second, it was written by my hero that I will be giving a speech as. Theodore Roosevelt, not only was a very influential president, he also was a great writer. I am excited to learn more about, travel, Roosevelt, and his writing style.

� Atlantic Rainforest (Brazil) ? Within this vibrant ecosystem are numerous rare plants, of which 70% are found no where else on Earth, and 20 primate species that are unique to this region as well. Wild relatives of the pineapple, cassava, sweet potato, and papaya are located here.

et al. (1991) in the northeast area of Patos Lagoon is also related to the Jacuí incised-valley systems (Baitelli, 2012; Weschenfelder et al. 2014). The incised-valley systems established along this coast have acted as geographic barriers that have isolated diatom communities as observed by Santos (2015). The freshwater taxa Aulacoseira veraluciae and Aulacoseira sp.2 are related to the Jacuí incised-valley systems while Pinnularia sp1 is exclusively related to the Camaquã incised-valley system, active from the Late Pleistocene to the Holocene. Similar correlations with incised-valleys were observed in a study about evolution of the skull shape of Ctenomys minutus (Rodentia-Ctenomyidae), based on an isolation-by-distance model that was shaped by selection and geological evolution of the coastal plain (Fornel et al. 2010). Similarly, Mäder et al. (2013) suggests that the geographic clades of Calibrachoa heterophylla, an endemic South-Atlantic species of petunia, formed when the coastal plain was deeply dissected by incised-valley systems acting as geographic

In this article we are presented with the effects of fire and wildlife dynamics in Western Amazonia. This a very intriguing article written by researchers at the Institution Technology Department of Biological Sciences in Melbourne, Florida. Researches both on local and regional scales were able to ascertain the question, if bamboo forests have historically covered an area as extensive as its current distributions? During the study, the intrigued wanted to uncover how the modern extent of bamboo could have resulted from the historical increases of fire presence and whether past invasions of bamboo dominance is persistent to the landscape and future state of Western Amazonia. Through the use of Landsat imagery, field surveys and other means of technology, these researchers were able to show the impacts of fire on bamboo in major cities of Los Amigos, Cocha Cashu, Peru, and Acre, Brazil.

Firstly, the rainforest’s wildlife demonstrates earth’s 8 evolutionary stages: The “Age of the Pteridophytes”, the “Age of the Conifers and Cycads”, the “Age of the Angiosperms”, along with the seperation of Gondwana, biological evolution and radiation during thirty-five million years of isolation, the beginnings and radiation of songbirds, the integration of Australia and Asia flora and fauna, and finally the tremendous effects of the Pleistocene glacial periods on tropical rainforest vegetation.

Only a century ago, South America's primitive forests blanketed the entire region from the southern tip of the continent north half the length of Chile's coast and eastward into Argentina's Patagonia. Beech trees of the genus Nothofagus covered most of the region, mixed with evergreen and various deciduous trees. Once extending more than 35 million acres, these forests comprised the largest stands of pristine temperate rainforest in the world (Nash 1994). Nothofagus beeches are among the most ancient species of trees and have been on Earth more than 150 million years. Soon after their arrival in the 16th century, European settlers began logging these forests, but not until the 20th century did widespread clearance begin. During the 1940s

Although relatively small in size, Ecuador is one of the most biologically diverse nations in the world. A drastic range of altitude and geographical diversity in such a small area has resulted in a high number of diverse climactic regions. Because of their very different climates and altitudes, Ecuador’s four main regions, the lowland Pacific Coast, the Andes Mountains, the Amazon rainforest, and the Galapagos Islands, are each home to a wide variety of plant and animal species. These many distinct ecosystems and the hundreds of endemic species residing within Ecuador’s borders have led scientists to classify it as a biodiversity “hotspot”.

What the main point of the article is about is the Andes Mountains or the Amazon River. It has to do with speciation because the changes in the landscape has diverged the species of each animal. Like the birds that Darwin studied the animals that adapted to the environment due to the climate or the resources that are relevant to the species. But the article says that “speciation occurred later” and what that means is most of the animals that were not use to the terrain died off until speciation took place to speed up evolution or natural selection.

Brazil has many awesome species in its rain forest , one of its animals is a Deadly Pronas. The pronas can hurt you in a bite and you might have to go to the doctors, pronase look like they do not have sharp teeth but they do. Pronas, are a tipe of fish that are very fast swimmers and have sharp teeth and are a small fish, Brazil's rainforest is disappearing almost everyday. Brazil has a nether animal that is snakes some of the snakes are poisonous and some are not poisonous. Some can hurt you and some can feck you.

Habitat loss and fragmentation are major threats to biodiversity and Brazil’s Atlantic Forest is a prime example of this. The Atlantic Forest of Brazil provides habitat for a wide variety of endemic species, but sadly it is one of the most endangered biomes in the world (biotropica). One of the endemic species of this biome is the Golden Lion Tamarin. A number of different human activities including deforestation for lumber extraction to agriculture, cattle ranching, and carchoal production, have drastically minimized the habitat of the Golden Lion Tamarins to small patches made up primarily of secondary vegetation (Atla Forest). Another factor that has contributed to the reduction in this species’ number was hunting (Atla). It has been estimated
