Invasive species
This refers to the animal and plant species as well as pathogens, which are not native inhabitance of a given land. The introduction of these animals to a new land is not recommended because of the harm they cause to the existing living organisms in that place (USDA). The invasive species create a significant change in an ecosystem in terms of constituents and the need for food and production. Initially, we have an ecosystem that has been balanced in terms of food chain and food web as well as the population growth. The introduction of the invasive species will create a new demand in terms of food, shelter and reproduction. As a result, the entire ecosystem will be disoriented.
Invasive Species in Region
Africanized bees, brown tree snake and Zebra mussels are examples of popular invasive species (USDA).
Endemic species …show more content…

They have limited chances of survival if they are transferred from their native region to another. The state of their ecological context is referred to as endemism. The endemic species often survive in unique geographical locations with specifically defined whether conditions, landscape, vegetation, and temperature among other things. They have developed special futures to adapt to that specific environment only (USDA). They can only survive in another area with similar conditions. It is important to note that organisms found in such specific places only become endemic when they are not found elsewhere. These species are restricted to a defined place with feature that supports their lives. Lemurs are examples of endemic diseases living Madagascar

In other words, when new animals were introduced to Europe, nothing happened to the environment. This was a positive effect for Europe seeing how they were only benefiting from the introducing of new animals. The Americas however, had a different reaction. The introduction of new animals caused a negative impact on their environment. It caused overgrazing, which is when farmers allow for grasslands to be grazed so heavily that the vegetation is damaged and the ground becomes liable to erosion.

According to the World Wildlife Fund for Nature organization, the Mojave Desert ranks as the smallest desert among the four existing in America. Just like any other desert, it faces numerous threats to its wildlife and environment. An example includes the introduction of invasive species into their territory. The University of Nevada agrees that the invasive plant numbers are growing mainly from the results of human disturbance, which is a tremendous issue that can harm both plants and animals. Invasive species affect the diets of desert animals, their existence, and the populations of native plants.

Invasive species have been a massive problem in Hawaii since the 17s and 18 hundreds. At first, it wasn’t that big of a deal, but the influx of invasive species grew over time, and it became a dangerous slippery slope. Species that were once alienated poured into Hawaii and destroyed indigenous species that had been native to Hawaii for a very long time. Since then, the Hawaiian people and advocates of removing invasive plants and animals have banded together to help remove these species. There has been a great global effort to remove invasive species in all places, but the hasty spread of them has made it almost impossible to eradicate a lot of them. I think my group can majorly help with this by educating you all about the seriousness of invasive species.

Keystone species are essential elements of ecological communities and have a disproportionate impact on the composition and operation of ecosystems. A keystone species is one that, in relation to its abundance, has an overpowering effect on its surrounding ecosystem. They influence many other organisms in an environment and help to decide the types and quantities of different other species in the community, all of which are essential to sustaining the foundation of an ecological community. The ecology would change significantly or vanish altogether if keystone species were absent. Keystone species, despite their significance, are frequently ignored in conservation efforts, which contributes to their decline and possible ecological effects.

They are silent killers, living in backyards, parks and neighborhoods all across the world. They specialize in crowding out, choking, and killing native residents to the point where they rule over the land. The prevention and elimination of these species cost billions of dollars to the United States each year. Our commercial, agricultural, and recreational activities depend on the execution of these visitors. According to the United States Department of Agriculture, these killers go by a less potent name: invasive species.

Exotic Animals Shouldn’t Be An Issue Exotic animal ownership is something that is highly debated by many people today and raises many questions. Should exotic animals such as: monkeys, tigers, lions and other such desert dwelling or jungle dwelling animals be allowed to be kept in captivity by humans. Or should they be able to just roam free in the wild? Many people would be inclined to say roam free because it is not “natural” for wild animals to be kept in captivity. Or they can potentially be very dangerous if they escape or turn on a person, they can also carry very deadly diseases.

Poaching and illegal hunting can cause an off set in the ecosystem by overhunting animals. When one animal population decline drastically, other organisms are affected too. The decline in native predators is the main cause for overpopulation of animals like deer. Deer overpopulation has led to rapid decrease vegetation life causing other animals to be put at risk. Removing predators from the food web disrupts the entire balance of an

Biodiversity is all life on the planet. How much life is out there, however, is still quite unclear and by this time, possibly many new species may find out.

This usually causes extinction within that species, and researchers have decided to do something about it. Although endangered animals are born in the wild, they should be sheltered and protected in nature parks because it helps decrease the amount of extinctions, allows a better and healthier environment, and the animals are protected from predators and human hunters. Endangered animals are to be kept in zoos because it decreases the amount of extinctions. Human activities have affected animals living in the wild dramatically throughout history.
