Ant and other invertebrate richness in the long-term study was initially superior in the seeded plot, with little difference between the planted and unplanted plots.
All that is certain is that McCann's confident 2000 verdict in favor of a positive diversity-stability relationship was premature.[55] Note, finally, that virtually no theoretical or practical exploration of this question has used concepts of diversity other than richness.
Our results suggest that increased attention to trophic interactions, diversity measures other than richness, and particularly the effects of consumers on evenness and primary productivity, will improve our understanding of the relationship between diversity and ecosystem functioning and allow more effective links between experimental results and real-world changes in biodiversity.
On the other hand, richness of OTUs per individual root sample did not vary by grassland site (F2,191 = 1.96, P = 0.14) or plant species (ANOVA, F7,191 = 1.51, P = 0.17), and no interaction between plant species and site was detected (F14,191 = 0.60, P = 0.54).
I thought of all the blessings I have in life and how I try to be mindful of sharing with others the richness of my life.
By contrast, most populations (with the exception of a few such as Khtada Lake and Canyon Creek) tend to show little divergence from each other in allelic richness resulting in overall low net values for allelic richness diversity (white bars, Fig. 4B).
On the other hand, the richness of a large set of process models also offers opportunities, for example with respect to the re-use of existing model parts for new models.
For the two other breeds, allelic richness was similar in each genetic group.
This test answers the question of whether positive contrasts in one variable (diversity of host use) are associated with positive contrasts in the other variable (species richness).
On the one hand there are the constraints imposed by CMC and, on the other, the social richness of the virtual group using it.
