Two different species can not live for long duration in the same niche...
Gause's hypothesis states that two different competing species cannot coexist together for a long in the same niche, one has to get eliminated by the other competing species, if they do coexist, then they do so as a result of niche differentiation, i.e. differentiation of then realized niches.

Two different species can not live for long duration in the same niche...
Gause's hypothesis, also known as the competitive exclusion principle, states that two different species cannot coexist for a long time in the same niche or habitat. This principle was proposed by Russian ecologist Georgy Gause in 1934.
Explanation:
- A niche is a specific role or position that an organism occupies within an ecosystem. It includes the physical space it inhabits and the resources it utilizes.
- Gause's hypothesis is based on the idea that two species with similar ecological requirements cannot coexist indefinitely in the same environment. They will compete for the same resources, and one species will eventually outcompete the other.
- The species that is better adapted to the environment will be more successful in obtaining resources and reproducing, leading to an increase in population size.
- The less successful species will have a reduced population size and may eventually be driven to extinction.
- Gause's hypothesis has been supported by numerous experiments and observations in ecology. For example, studies of bird species on islands have shown that closely related species with similar beak shapes and feeding habits cannot coexist in the same habitat.
- However, there are exceptions to the competitive exclusion principle. For example, species may partition resources in different ways or adapt to different aspects of the environment to reduce competition.
- Overall, Gause's hypothesis highlights the importance of resource competition in shaping ecological communities and the potential for one species to dominate and exclude others in a given niche or habitat.

Two different species can not live for long duration in the same niche...
As the species will compete for the natural resources available to them. And one of the species may undergo evolution and adapt themselves more nicely to the same habitat than the other as a result of which the other species may have a lack of resources and after a certain time period it may become extinct. Gause's Hypothesis
