"ecosystem equilibrium" is correct and usable in written English.
You can use it in any discussion about the balance of an ecosystem. For example, "The river ecosystem is in equilibrium, with all of its species playing an important role in maintaining balance."
Results indicate that increasing tourist flow and related infrastructure are not perceived as threats to the local ecosystem equilibrium, but the problem of water quality should be carefully considered to prevent future negative feedback.
Diversification of prokaryotes attracts much attention from ecologists because it plays a critical role in ecosystem equilibrium and dynamics.
Armed with this information, analyses can be carried out to determine the impact of each individual organism's phenotype on the population's phenotype, and to identify how specific population phenotypes will interact to affect ecosystem equilibrium and community stability.
In stable ecosystems, equilibrium exists in the use of available resources.
It has been established that the aquatic ecosystem in equilibrium with minerals has a certain reserve potential, by which the equilibrium is governed and one of its parameters is maintained constant (Povar and Rusu 2012).
Is has been established that aquatic ecosystem in equilibrium with minerals has a certain potential reserve, by means of which the equilibrium is adjusted and one of its parameters is maintained constant.
In some experiments we also investigate the amount of environmental forcing required to push the ecosystem out of equilibrium in one pattern of species densities and into the attractor basin of another stable equilibrium.
Even the most modest increase in temperature throws the ecosystem out of equilibrium.
Consistent with an equilibrium ecosystem model, our results highlight striking cycles of community departure and recovery tightly coincident with the temporal evolution of Earth's climate, that is atmospheric CO2 concentration and atmosphere/ocean physical forcing (Figure 4C E).
During the year 2006, the cumulated NEE was +29 ± 16 g C m−2 (±CI) indicating that the site was close to an equilibrium ecosystem.
This is consistent with a non-equilibrium ecosystem (Angassa and Oba [2007]).
