1. Define keystone species. 2. Find an example of a keystone species. 3. Why is it considered a keystone species? 4. What is the current population status? Any current threats?
1. Keystone species is a species whose very presence contributes to a diversity of life and whose extinction would consequently lead to the extinction of other forms of life. Keystone species help to support the ecosystem (entire community of life) of which they are a part. 2. Prarie dogs 3. Their burrows act as homes to other creatures, including burrowing owls, badgers, rabbits, black-footed ferrets, snakes, salamanders, and insects. Their burrowing activity works to loosen and churn up the soil, increasing its ability to sustain plant life. Their foraging and feeding practices enable a more nutritious, diverse and nitrogen-rich mixture of grasses and forbs (broad-leafed vegetation) to grow. The enriched vegetation attracts an amazing array of wildlife who graze in their colonies. Black-tailed prairie dogs play an integral role in the prairie food chain; they are a critical food source for such animals as the endangered black-footed ferret, swift fox, coyotes, hawks, eagles and badgers. 4. Prairie dogs are suffering a catastrophic population decline in Colorado and other states. They are routinely poisoned, bulldozed and shot, and this situation is compounded by development, agriculture and the capture of animals for the pet trade.

They help controle the deer population 4.Conservation threats to the species include persecution as a pest animal, degradation and fragmentation of its habitat, and depletion of its prey base. Sufficient range and habitat corridors are critical to sustaining viable cougar populations.
1.Keystone species is a specie that has a much effect on the environment than other species in its community. 2.Elephant. 3.In Africa elephants are such large herbivores that they help to shape the environment around them by destroying trees and making room for other animals. 4.The number of elephants have greatly decreased over the years due to hunting and loss of habitat.
1. a keystone species is a species that plays a significant roll in diversity it's habitat. The extinction of this species would result in extinction of other species.
2. an example would be a sea otter.
3. the sea otters keep the sea urchins in check, and if the sea urchins over populate, they'll eat kelp beds, which are key habitats for spawning fish.
4. In the 18th and 19th century, russians and europeans hunted them. Since the 20th century, people have been working harder to protect them, and even reintroduce them.
1. A keystone species is a animal that helps other animals and other animals would die if this one died. 2.Grizzly bears 3.There the predators for elk and moose. and fish 4.No threats
1. A species whose presence and role within ecosystems has a major effect on the other organism within the system.
Turtles.
The gopher tortoise is a keystone species of the longleaf pine ecosystem-over 360 other species use tortoise burrows. .4. There are an estimated 1,674,000 gopher tortoises in the wild. Threats- Habitat loss, logging, disease, and road mortality. When developers want to build on an area that is gopher tortoise habitat, they either have to relocate the tortoises or take out an incidental take permit and then bulldoze over them
1. Keystone species are species that decide weather a habitat lives or dies depending on if they are around or not.
2. Sea Otter
3. Sea otters keep urchin populations stable, kelp beds are nurished, fish nusuries are kept alive and overall fish population increases and stabilizes at healthy populations.
4.European and Russian trappers hunt sea otters to near extinction.
1. Keystones are made up of species that make an ecosystem healthy. With out keystones play predator- prey roles.
2. Wolves
3. With out Wolves the elk were browsed the river bed and wilows alot. With the reintroduction of the Wolf, the Wolf can help elevate the number of elk and save the river bed.
1) keystone species are the architects of biodiversity they keep things functioning and balanced within the food chain
2) wolves
3) in there absense in yellowstone elks browsed willows in river and creek bottoms excessively , and now that there back riparion areas have come alive
4) at the end of 2008 at least 124 wolves in 12 packs and various groups occupied yellowstone/ died of high mortality and disease
