The phrase "a reduced population" is correct and usable in written English.
It can be used when discussing a population that has decreased in size due to various factors such as environmental changes, disease, or human activity.
Example: "The conservation efforts were aimed at restoring the habitat to support the wildlife, which had suffered from a reduced population over the past decade."
Alternatives: "a diminished population" or "a smaller population".
Because a reduced population density found at an expanding front may potentially reduce the selective advantage of cannibalism, one could have predicted a change of the norm of reaction of cannibalism to individual density during the spatial expansion of an invasive area.
Malone also said he believed the Hornets could succeed here despite low attendance, a reduced population and a weak economy.
"It's a very good argument, saying that we're saving animals that nature's weeding out, but when we're dealing with a reduced population as a result of human activity, we almost have to.
We further show that cholesterol depletion and antagonist treatment result in a reduced population of higher-order oligomers.
We conclude that the increased threshold current density for x= 0.33 has to be attributed to both, a larger leakage current and a reduced population ratio.
Another example was the plan of the federal government to redistrict shrinking Michigan cities, aiming at levelling shifting demographics on the vast urban territory with a reduced population (The Huffington Post 2012).
Remarkably, both a strongly reduced population size (∼1,200 sexually active individuals) and universal circumcision had a much weaker effect on the spread of ill-adapted HIV in the simulations.
Structures 4 and 8 have been investigated, revealing that Buena Vista was probably occupied from the Middle Preclassic through to the Late Classic, with a much reduced population in the Early Postclassic.
These elevated rates suggest that the symbiont is accumulating deleterious mutations as a result of a reduced effective population size, likely due to population bottlenecks experienced during maternal transmission.
Applying the PSMC to data simulated under the bottleneck history inferred for the pigs (Table 2) gives a shorter period of reduced population size than the empirical plot.
However, a reduced effective population size and reduced selection efficacy would be expected to impact all genes similarly (with some stochastic variance aside).
