Chaetomys: Vulnerable Species Analysis
The free-ranging bristle-spined porcupine (Chaetomys subspinosus) is part of a group rodents of suborder Hystricognatha and family Erethizontidae. The species has arboreal habit, it is medium-sized and endemic to Atlantic Forest. Its coverage area runs from southern state of Sergipe to north of state of Rio de Janeiro. Once considered abundant, but because of change and reduction of its natural environment and hunting, this rodent population is in decline. This framework made it to feature as "Vulnerable" species on the official list of Brazilian fauna extinction Threatened (Brazil, 2008) and the Red List of the International Union for Conservation of Nature and Natural Resources - IUCN. Their inclusion in these lists reveals ample opportunity …show more content…
subspinosus. Check that occurs correlation between genetic and geographic distance. Estimate the relationship between pairs of individuals sampled in order to support the development of efficient strategies for in situ conservation of the species. To elucidate these proposals work has been structured into five chapters: chapter 01 describes the detection, isolation and genetic characterization of Toxoplasma gondii isolates of C. subspinosus; chapter 02 is identify the tick species Amblyomma longirostre that parasites sampled C. subspinosus of individuals indicating the presence of Rickettsia bellii and Rickettsia amblyommii; chapter 03 was carried out to identify pathogenic and nonpathogenic bacteria present in the modified spines of C. subspinosus; chapter 04 deals with the development and characterization through next-generation sequencing (NGS), 30 unpublished microsatellite markers, polymorphic and specific to the species; and chapter 05, developed markers were used as molecular tools to assess level of structure and genetic diversity, gene flow, allelic composition of C. subspinosus. With biological knowledge obtained at end study can indicate measures for control of possible diseases caused by zoonotic agents detected and subsidize conservation

    Coypu Or Nutria

    The invasive species known as the, “Coypu” or “Nutria” are rodents who were brought to the United States for trade. Originally relocated here from South America, the coypu were used for their fur for trade in 1889. When the trade of Nutria fur crashed, the rodents were released into the wild. Currently, the animals reside mostly in Texas and Louisiana. Coypu prefered diets consist of roots, rhizomes and tubers of cattails, cordgrass, and bulrush. The Coypu species is mainly a problem in Louisiana and Texas.…

    Two Toed Sloths

    Thank you for inquiring your data to our organization. We have completed an inventory of the biological diversity in Central America and interpreted the distribution of the Choloepus hoffmanni (two-toed sloth) and Bradypus variegatus (brown-throated three-toed sloths). The possible locations the sloths could be located are, agriculture (AG), low land old growth (LL OG), low land secondary forest (LL SF), mountainous old growth (MTN OG), mountainous secondary forest (MTN SF), and finally clear cut (CC). Our organization totals there to be a total 136 sloths to be in AG, 144 sloths in LL SF, and finally 75 sloths in LL OG. On the other hand, there are no sloths found in MTN OG, MTN SF, and CC. Given the data regarding the location of both the…

    Jaguundi Habitat Destruction

    Jaguarundi is an extremely rare animal in Northern Mexico, and it is one of the world’s endangered animals. Habitat destruction poses the most severe threat to its existence. Land and agricultural development lessens the Jaguarundi’s population in Arizona and Texas in the United States. We know very little about this small cat species’ behaviors and reproductive biology, as well as its number in natural habitats. However, one certain thing is that, if the jaguarundi is in a confined environment, its breeding rate…

    1491 Charles C Mann Analysis

    Mann writes about how the Indians shaped and altered their land to suit their needs. The Indians used fire and rich soil, “black earth”, to do so. Mann writes “ Indians were the Keystone species of American ecosystems...removing them, results in a relatively significant shift…”. A keystone Species is a species that “affects the survival and abundance of many other species”. Evidence suggests the “black earth” covers ten percent of Amazonia. When the Indians were populous, they kept down the populations of animals by hunting them. Once diseases killed the Indians, there was a great boom in the animals populations and their now vast habitats. This provides a reason for Hernando de Soto’s expedition not encountering any bison, while later, when the French traveled down the Mississippi hey encountered bison.…

    American Dog Tick Research Paper

    The Ixodida is better known as the tick. Once who also have a significant amount of medical importance is the Dermacentor variabilis, better known as the American Dog tick. The American dog tick has a medical importance related to being a major vector for Rocky Mountain spotted fever (RMSF), tularemia (hunter’s disease) and even canine tick paralysis. Some of which have been known to be fatal depending on the situation. Not all of which are deadly. Their normal habitats are known to be grasslands, forest, mountains, and densely wooded areas which all contain a good amount of host for them to feed on. Ticks are ectoparacites and they transfer viruses and diseases by feeding. The adult tick is the tick which transfers the virus, etc. to the human since most larvae and nymphs don’t feed on humans. From the start they have not adapted to all seasons therefore they are usually active during the late spring to beginning of fall; with reproduction being in the summer…

    Two Different Suborders Of Primates

    Primatologists have studied about them and categorized them as a separate group. Through the primate taxonomy, there are two suborders which separate all primates into two groups. Each of two suborders, strepsirrhini with moist nose and haplorrhini with dry nose, has specific characteristics. This paper analyzes two primates, lemurs for strepirrhini and chimpanzees for haplorrhini about why they are in danger from extinction and what characteristics and social groups they are consisted. Even though lemurs and chimpanzees are in different group and live in different environment, both are threatened from habitat destruction and hunters. Since people have meddled their environment, population of lemur limited. There is not only this reason, but also there are more reasons that lemurs are on verge of extinction. Some people go to Madagascar and take some of lemurs because people sell them as rare pet animals or bushmeats by cooking them. These selfish human behaviors make number of lemur decreasing in large percentage. Numbers of chimpanzee also decreases enormously because of same reasons with lemurs. Even though chimpanzee shares 98 percent of DNA…

    The Culture of the Huaorani of Ecuador

    “In the Eastern part of Ecuador stretches el Oriente, the jungle. Between the Napo and Curaray Rivers are 600,000 hectares of land that is the home of the Huaorani, feared warriors of the Amazon Rainforest. This territory includes Yasuni National Park, one of the most bio-diverse places on the planet. Unfortunate for the Huaorani, it also includes hundreds of kilometers of oil pipes and several oil company stations that are having a devastating effect on this fragile tropical ecosystem” (Cuna, 2007, para. 1). Due to encroachment on their territory by outsiders, there are fewer than 2,000 Huaoranis left today. In this paper, I will provide an overview, as well as analyze and evaluate how the foraging mode of substance impacts the Huaorani through the following aspects of culture: Beliefs and values, Gender relations, and kinship.…

    The Rainforests of Atsinanana is located on the eastern side of the island of Madagascar. There are six different national parks that are not connected to one another that make up the “Rainforests of Atsinanana”. These rainforests are said to be possibly the most diverse ecosystems in the world. They consist of 2,598 species of animals (from 166 families) and 1,039 plants (from 119 different groups). These national parks also contain more than 1/3 of all mammals found on the island of Madagascar. The biodiversity of this group of forests is what makes the places so unique.…

    Primate Environment

    The impact of the environment condition of primate population has been well documented. Replacement of forest area by crops and soaring urbanization are often described as significant drivers to survival of wildlife populations, including non-human primates (Laurance et al. 2002). Given the rapidly of forest replacement, at present many primate species face the dramatic disturbance and fragmentation of their natural habitats (Cowlishaw and Dunbar 2000). At the same times, human activities in the forest have also damaged to an increased the probability of primate to share habitat with humans who interact and compete for space and resources (Isabirye‐Basuta and Lwanga 2008). Most primate species are threatened and avoiding live with human, while…
