What are the different types of niches?
K-selected species possess relatively stable populations and tend to produce relatively low numbers of offspring; however, individual offspring tend to be quite large in comparison with r-selected species.
What is a niche for a bird?
Bird Niches in its Habitat. A niche is the role of a particular species — what it does — within its habitat. No two species perform precisely the same role in a particular habitat, at least not for long. If they do, competition for food and a place to live results, and one species eventually excludes the other.
What is a niche specialist?
A generalist species is able to thrive in a wide variety of environmental conditions and can make use of a variety of different resources (for example, a heterotroph with a varied diet). A specialist species can thrive only in a narrow range of environmental conditions or has a limited diet.
What is a keystone species?
A species whose presence and role within an ecosystem has a disproportionate effect on other organisms within the system. A keystone species is often a dominant predator whose removal allows a prey population to explode and often decreases overall diversity.
