Sentence examples for reduction of diversity from inspiring English sources

An integral part of agricultural intensification at the plot level is the deliberate reduction of diversity.

Severe reductions of diversity often are associated with invasion; for example, genetic diversity is reduced by nearly 35% in NA populations of I. purpurea compared with their native Mexican populations (Fang et al. 2013).

This scenario also leads to more extreme reductions of diversity at X-linked loci, which is what is observed in the non-African strains at the loci in the combined dataset.
