Underlying causes and the future of regionalscale plant diversity. Taxonomic and functional diversity change is scale dependent.

Scale dependence of the beta diversityscale relationship core. The relationship between the number of species and the area sampled is one of the oldest and bestdocumented patterns in community ecology. Moreover, our results suggest recent theory on scaling biodiversity stability relationships 25,29 which has mostly been tested with sessile organisms like plants 26,46,47, 71 can be. Progress in this topic was constrained by a limited ecological understanding of the. Instead of one process determining changes in species richness across a wide range of scales, different processes might determine plant biodiversity at different.

Scale dependence of the correlation between human population presence and vertebrate and plant species richness. Scavengers or birds feeding on plant matter increased in their assemblage prevalence at local and intermediate scales, but stagnated toward. We explore the scale dependency of beta diversity and scale relationship, both. Species richness, hotspots, and the scale dependence of. Because biodiversity is multidimensional and scaledependent, it is challenging to estimate its. Currently, it is unclear how n enrichment affects biodiversity at scales larger than a small plot. Scale dependence of the diversitystability relationship. At similarly broad scales, many conservation studies are examining the richness of rare or threatened taxa 811 and their distribution in relation to existing reserve networks 1214. The results showed that the slope of the loglog plot varied systematically with spatial scale. However, our understanding of network structure may depend upon the temporal sca. Several theoretical models and field data from a wide range of plant and animal taxa suggest that the slope, z, of a graph of the logarithm of species richness against the logarithm of area is roughly constant, with z.
