Species richness(S) is the number of species within a defined region. The species richness of a region is obtained through sampling or via a census. Because “region” is defined by the observer, species richness has been further categorized into three components to account for changes in spati...
Stand age and species richness dampen interannual variation of ecosystem-level photosynthetic capacity (vol 1, 0048, 2017) The total uptake of carbon dioxide by ecosystems via photosynthesis (gross primary productivity, GPP) is the largest flux in the global carbon cycle. A key ecosystem functional...

Average species richness did not change during the last decades. Species turnover rates were not related to the degree of anthropogenic eutrophication or to the intensity of fishery exploitation in these lakes. On the species level, however, one effect of accelerated eutrophication is apparent, the...
diversity, we reconstructed a genus-level phylogenetic tree (1987 of the 2713 genera) and compiled an extensive database of abiotic, biotic and geographical characteristics to assess whether differences in these traits correlate with the vast asymmetrical species richness among genera present in this ...
Therefore, we need better understanding of mechanisms that drive changes in diversity of local communities and of differences in temporal trends between components of local diversity, such as species richness and species turnover rate. Freshwater ecosystems are vulnerable to multiple stressors, and ...
Explanations of the pattern of species richness have traditionally relied on small-scale, local processes occurring in ecological time. Differences in spec... M Zobel 被引量: 0发表: 1997年 The relative role of species pools in determining plant species richness. An alternative explanation of specie...
The order Hymenoptera (bees, ants, wasps, sawflies) contains about eight percent of all described species, but no analytical studies have addressed the origins of this richness at family-level or above. To investigate which major subtaxa experienced sign
Understanding large-scale variation in species richness in relation to area, energy, habitat heterogeneity and anthropogenic disturbance has been a major task in ecology. Ultimately, variation in species richness results from variation in individual species occupancies. We studied whether the individual ...
Species are numbered and aligned by their IDs (see Appendix A: Table 2 for species names). The rightmost estimate is the mean community value (μβ1). (C, D) Inferred species richness/abundance–area relationships based on species-level models. Collected number of species/individuals per ...
