Therefore, to estimate species richness at the regional level, they fitted Fisher’s log series to empirical species abundance data, quantified the effect of conspecific aggregation on these estimates via simulation, and applied quantified corrections to give more accurate estimates of regional species ...
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 ...
Biodiversity richness (approximately 1350 plant species in the Nieuwoudtville area) and the occurrence of rare and endangered plant species have earned the Bokkeveld Plateau recognition as a global biodiversity hot spot, with high levels of endemism of geophytes in particular (Manning and Goldblatt,...

明确丛枝菌根真菌(arbuscular mycorrhizal fungi,AMF)侵染率对喀斯特坡地坡位与物种的响应及其关键影响因子,是合理利用土壤AMF促进喀斯特植被恢复的前提。该研究在充分调查喀斯特峰丛洼地典型灌丛坡地环境背景信息的基础上,采用曲利苯蓝染色-镜检法检测并计算典型灌木黄荆(Vitex negundo)、红背山麻杆(Alchornea trewioides)...
Variation coefficients ofnSSR data for each locus and population were calculated by GenAlEx v6.5 [112], includingHe(expected heterozygosity) andA(number of alleles) for loci,He,Ho(observed heterozygosity) for each population. To avoid bias from unbalanced sample sizes,Ar(allelic richness) for each...
, 1996). This definition retained the essence of Paine's original usage, but expanded it more broadly to include species other than predators. Power et al. (1996) stressed the importance of having a rigorous, quantitative method of assessing the community- or ecosystem-level effects of a ...
Nevertheless, multiple studies on various taxonomic groups within plants, vertebrates, and invertebrates have used outline distribution to find differences in species ranges or species richness (e.g., Hawkins et al. [59]), including macroecological studies on European dragonflies similar to ours (e....
