For evolutionary biologists and ecologists, one of the goals of DNA barcoding is to understand the origin of species and the factors causing the difference in species richness in different biomes across the globe.
Furthermore, the difference in species could also give different results.
The difference in species richness likely reflects different habitat diversity between the two sites.
Interestingly, the slope of the Holocene SAR is not significantly different than the slopes of the Barstovian and Rancholabrean ones, indicating that the difference in species composition between provinces changed very little, if at all, even in the face of the shift of world climate into ice ages (the Pleistocene) and the Holocene diversity decline.
The difference in species, model used, and time of study may account for the different observations regarding distal organ apoptosis.
No pronounced difference in species' reaction to the level of urbanization was observed.
No difference in species richness was observed but community evenness was greater in CO than RE-3m.
There was a clear difference in species richness and composition between the organic and conventional study sites.
No difference in species composition dissimilarity (beta diversity) was recorded indicating that no biotic homogenization had occurred between 1994 and 2015.
At the village scale, however, the cropping system only appeared to influence intraspecific richness as no difference in species richness was found between villages.
While no significant difference in species richness was found between FI and FM, OP were characterized by a strongly impoverished fauna.
