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.
Issues such as habitat loss, grazing, tourism, threatened native species, feral animals in the Mount Kosciuszko. The reasons for this dramatic decline in Human-induced modification and natural induced. Early generations of grazing and practices such as deforestation have also played a major role in the ecological disaster that is the Mount Kosciuszko. (Map of Mount Kosciuszko) Mount Kosciuszko is incredibly diverse weathering many different ecosystems, forests, , mountain ranges. The Mount Kosciuszko supports a significant portion of Australia’s biodiversity including species of flora and fauna found only within the Mount Kosciuszko; pygmy possum, broad tooth rat and the spotted tail quoll.
Firstly, the Everglades are an important ecosystem which reduces flooding and replenish aquifers but human actions are having a huge impact on the landscape. The rapid urban and agricultural development in the area has decreased the size of the wetlands dramatically which affects the organisms found there. This is especially important as it is home to several endangered species. Not only that, but invasive species that threaten existing wildlife by preying on or competing with them. According to Everglades.org, they’ve “contributed to nearly 70 percent of extinctions in the United States” and are the “primary cause of species endangerment.” The water itself is a major cause of decline to the area, firstly because of poor water management leading to water levels being too low or too high at the wrong times has caused a decline in many species.
The Rideau River Ecosystem and Food Web Team A BIO/101 Brian Fox The Rideau River Ecosystems are biological populations of interacting organisms and their physical surroundings. Many are areas of lands that have changed due to the nearby water currents. These areas of land are home to many animals and plants that have adapted to survive. Each individual ecosystem is comprised of different features that make it conducive to certain plants and animals. That means each ecosystem is unique.
In this environmental disaster, 10 cubic meters of water and 4.5 million cubic meters of potentially toxic slurry were spilled into virtually untouched forest, lakes and rivers. If something like this happens at the Pebble Mine, then most of the fish and wildlife in Bristol Bay would be in danger of being killed. A species that would be greatly affected by this is the sockeye salmon. More than half of the world’s population of these fish lives in Bristol Bay. This means that the survival of this species would be threatened.
There are about 10,000 animals on the endangered species list. That is a big number that needs to be brought down in order to maintain biodiversity. However, that number is slowly shrinking thanks to the endangered species act passed in 1973. This act authorizes the listing of species as endangered and threatened, prohibits unauthorized taking, possession, sale, and transport of endangered species, provides authority to acquire land for the conservation of listed species, and authorizes the assessment of civil and criminal penalties for violating the act. One of these endangered animals is the Florida Panther.
Florida Panthers The Florida panther is a highly endangered type of cougar (Puma concolor) that survives in the low pinelands, palm forests, and swamps of southern Florida in the United States. These animals are currently only occupying five percent of their historic range. Today there are about eighty to one hundred living panthers. There are many biological issues concerning the Florida panther that include: habitat loss and fragmentation, automobile accidents, territorial disputes among panthers, inbreeding, and disease. A major concern to non scientists is the danger to domestic animals and livestock.
Assess the strength of the argument that highlighting the economic value of biodiversity is the way to ensure conservation of the worlds ecosystems. What is Biodiversity? Biodiversity refers to the existence of a large variety of living organisms in an area, including plant and animal species, the diverse genes they have, as well as different types of ecosystems provided in our planet. In other words, biodiversity is everything embracing life on Earth. The loss of biodiversity around the world has become acknowledged as a growing issue globally.
The Great White has only one natural predator, the orca. There is very little known about the population status of this shark, however it is uncommon compared to other species. The IUCN has given it a label of being vulnerable, but not yet an endangered species. Fisherman go for sharks to collect their teeth and fins. There is a 250,000 dollar fine for anyone who is caught fishing for a Great White.
