How does keystone species do to an ecosystem?
The keystone species in any given community protect other species from their predators, so that those species are able to function correctly and do their jobs, or add their contribution to keep the ecosystem up and running.
The idea that the destruction of one species in a community could greatly affect other members of the community has its roots in the hypothesis of community structure proposed by?
Clements
The factors that affect the species diversity?
-Invasive species- When a new species that is not native moves into an area, it often won't have natural predators and can thus survive better than natives. They take over, and lower diversity levels by killing off other species -Keystone species- a keystone species is a species which many others in the food chain rely on, if the keystone species has a problem or decrease in population the diverersity of the population will also decrease. - Availability of resources- For instance food, shelter, nutrients, notice that rain forests which are abundant in rain forests show much diversity, while a tundra shows very little diversity. - Stability of the community- for instane, tempreture shifts will cause a decrease in diversity because certain species have a small range of tempreture that they can live in. This is why coral reefs are decreasing in diveristy, they are very limited in teh tempreture they can live in. I wouldn't agree that natural selection affects diversity levels as it is present at all times, in every ecosystem and does not fluctuate.
What is reproductive species concepts?
Species are community of populations that are reproductive isolated from other and that occupy a specific niche. Such sister species can live in sympathry.
How would an ecosystem be affected by the extinction of a plant wihin a habitat?
That depends on the type of ecosystem. There are two answers to this question based on two conflicting and opposite theories that ecologists have developed. Neither is right or wrong; one may be true in one ecosystem, but not in another.Individualistic hypothesis:The structure of a community is dependent on abiotic factors only; species are independent of other species and are only in a geographical location due to nutrients, temperature, etc. The extinction of another species will not affect others.Interactive hypothesis:Members of a community are dependent on each other and are closely linked. Biotic interactions cause the community to work as a whole with each species doing their part. If one species were to be removed, the other species would be greatly affected.
A keystone species is a species whose presence does what?
A keystone species is a species whose presence has an influence on the size of the population of several other species in its community. A jaguar would be an example.
What is keystone species?
Keystone species are those which play a major role in determining which species exist in a particularcommunity. They are critical factors in ecological processes such as energy flow and nutrient cycling.If we can identify a keystone species and quantify its impact on its community then we can usually understand how the community functions as a whole. The importance of these species is such that their loss from a community may bring about a cascade of other species extinctions. Often a keystone species is not recognised until it is wiped out and many other species which were dependant upon it disappear also.

The keystone species in any given community protect other species from their predators, so that those species are able to function correctly and do their jobs, or add their contribution to keep the ecosystem up and running.
A large number of species are dependent on?
A large number of species are usually dependent on the Keystone species. The Keystone species usually regulates the abundance of the other species.
Are mosquitoes a keystone species?
A keystone species is one that other lifeforms in an ecosystem depend on. Mosquitoes are a keystone species because they are extremely low on the food chain, and if they were removed from an ecosystem, the food supply would be interrupted.
What name is given to a species in an ecosystem upon which a large number of other species are dependent?
This is a "keystone" species.

Clements
Can a species be both umbrella species and keystone species?
Yes, it is possible for a species to be both an umbrella species and a keystone species. Lemurs in Madagascar are an example of both a keystone and umbrella species. They are a keystone species because a certain kind of plant seed needs to go through their digestive system and be excreted before it's capable of germinating in the soil. They're also an umbrella species because their plight has been used in conservation efforts that have also helped other species that live in their habitat.
What is the name for a species that influences on the survival of many other species in your ecosystem?
The term is biodiversity. High biodiversity means a large number of different species in an ecosystem. An ecosystem with many different species is less likely to be disrupted by environmental changes.
What is the keystone species in the savanna?
A species whose presence and role within an ecosystem has a disproportionate effect on other organisms within the system.Other kinds of keystone species are those, such as coral or beavers, that significantly alter the habitat around them and thus affect large numbers of other organisms.
What is a nichie in a community?
A niche in a community is the level at which a species ranks among other species in it's community.
How can species richness affect community stability?
Having a variety of species in a community is great, but the downside is that if a community just keeps conditions the same, some species need different conditions in order to survive. But on the other hand, some species will grow in large numbers if their certain conditions are kept the same.Having a variety of species in a community is great, but the downside is that if a community just keeps conditions the same, some species need different conditions in order to survive.
