Sentence examples for decrease in the species from inspiring English sources

However, the presence of herbicide was associated with a decrease in the species richness of recorded protist taxa and a predominance of robust, cosmopolitan or ubiquitous protist genera.

The nitrogen deposition range in Denmark is relatively small and when only considering the Danish data a non-significant decrease in the species richness with nitrogen deposition was observed.

This pattern is characterized by steady decrease in the species richness from the tropics to northern or southern locations, and is called the latitudinal diversity gradient.

Population establishment and long-term persistence as well as long-term evolutionary potential of restored populations is ensured by within-population genetic diversity (McKay et al. 2005), as loss of genetic diversity can lead to a decrease in the species' ability to survive environmental changes and demographical fluctuations both in short and in long term (Ellstrand and Elam 1993).

Sexual dimorphism is generally decreased in the species, meaning the females have little difference in their body size and colour from their male counterparts.

Further, decreases in the species diversity of potential host assemblages have been associated with increased prevalence of infection by zoonotic pathogens in host populations both for vector-borne diseases (Ostfeld and Keesing 2000) and for nonvector-borne zoonoses (Mills 2005).

A significant decrease in the chondrichthyan species richness, accompanied by an analogous decline in their abundance (catch composition and catch rate), was the most striking outcome.

There was a decrease in the overall species richness, diversity, evenness and abundance of individuals in oil palm compared to forest, both at the habitat scale (Fig.  1; Table  2) and on individual transects (Table  2; LME: species richness, F3,12 = 18.39, P < 0.001; abundance F3,12 = 12.51, P < 0.001; species diversity F3,12 = 16.14, P < 0.001; evenness F3,12 = 5.99, P = 0.01).

The overall loss of functional richness with decreasing pH was coupled with a small decrease in the number of species within FEs, with the mean number of species in each FE declining from 8 in ambient and low pH zones to 6 in extreme low pH zones (Supplementary Figure 4).

This may lead to a decline in herbaceous species in the short term, and a decrease in tree species in the long run due to an increase in mortality and reduction in seedling recruitment.

The rapid decrease in the diversity of species of Fagaceae north of about latitude 35° to 40° N lends support to this hypothesis.
