Sentence examples for changes in richness from inspiring English sources

Mammals showed no changes in richness, abundance and composition.

We describe changes in richness, diversity, and species composition of fungal communities of trembling aspen logs and snags caused by these silvicultural practices.

By looking at changes in richness over time, we found that fragmentation affected the dynamics of species richness, as opposed to static values of species richness.

Many studies use annual monitoring to quantify changes in richness or abundance of communities, yet few studies explicitly test for progressive changes in community similarity.

Unexpectedly, decreases in progressive similarity resulted from small changes in richness (<1 species per route for the 22-year study period) and modest losses in abundance (−28.7 −10.2 individuals per route) that varied by migratory habit and nest location.

So as not to average out changes in richness across several years, we only calculated this metric when the surveys of a given plot were separated by one year.

Assessments of the ecology of the microbiome in obese individuals have shown an increase in the change in richness and diversity of the microbiome following gastric surgery.

Changes in genera richness proved more reliable in predicting changes in species richness than changes in family richness.

The time-scale of changes in species richness differs between these systems, with a drought impact on species richness already occurring during dry seasons in (semi- arid semi- aridite & systemsrg, 2005; Stromberg et aLite2005, 2007, 2009) and a more gradual response in more temperate regions, where changes in species richness may take several to many years.

Rather than comparing forest fragments to continuous forest at a single point in time, we evaluated the effects of fragmentation on changes in species richness through time, focusing on three main questions: Does habitat fragmentation reduce species richness, and do changes persist over time?

Biomass change was only marginally related to changes in plot richness (F1,57 = 3.43, P = 0.07, R2 = 0.06), and when both PD and richness change were included in a single model explaining biomass change, PD change was a significant term while richness change was not (PD: t = 2.712, P = 0.009; richness: t = −0.828, P = 0.411).
