The phrase "ecological alteration" is correct and usable in written English.
It refers to changes or modifications in the natural environment or ecosystem. Example: The construction of a dam on the river caused significant ecological alteration in the area, disrupting the habitat of several species of fish and altering the flow of the water.
Sensitive species may be impaired by sublethal effects or decimated by lethality, and this ecological alteration may initiate a trophic cascade or a release from competition that secondarily leads to responses in tolerant species.
The study advocates for basin based cooperation that can address ecological alteration and resource degradation.
While we know that ecological alteration affects evolutionary futures of species and populations, we know less about the predictability or the consequences of these changes (Hendry et al. 2011; Sih et al. 2011 Barrettt and Hendry 2012; Palkovacs et al. 2012).
Biodiversity monitoring programs should set a collection protocol, using a robust sampling design, with sufficient survey effort, spatial replication, methodological consistency and time to detect eventual ecological alterations.
We therefore hypothesize that such changes, and associated modifications in water properties, underlie, together with the temperature changes, the ecological alterations described in both sub-basins.
However, more research into linking endocrine disruption to behavioral and ecological alterations in free-living animals is needed before conclusions regarding this feeding behavior can be drawn.
Therefore, a number of approaches to remediate these deficits, such as cognitive remediation, pharmacology and ecological alterations in the classroom, have been proposed.
Mahseer populations have been declining in most of their natural habitats due to impacts caused by industrialization, urbanization, and agricultural development causing ecological alterations and physical changes in natural environment in lakes and rivers of mid hills (Das and Joshi, 1994; Shrestha, 1994).
Finally, based on the combined habitat suitability index flow alteration and ecological response relationship was established.
Poff, N. L. et al. The ecological limits of hydrologic alteration (ELOHA): a new framework for developing regional environmental flow standards.
However, identifying clear ecological responses to flow alteration can be a significant challenge, because of the complexity of river systems and the other factors which may confound the response.
