Chief among these is commitment [ 10] and persistence [ 13] and these have been linked to the level of activity and the richness of the virtual environment.
The typical butterfly assemblages on ECA grassland might be linked to the slightly higher plant species richness due to management restrictions.
Our study on gibel carp showed that higher parasite species richness is linked to the expression of the alleles of the DAB3 lineage.
For the sipunculans, richness may be linked to the temperature of the water masses during the year [289], which reflects a physiological barrier between cold and warm water for cold- and warm-water species.
Species richness, abundance and biomass were linked to the availability of suitable substrates.
The effect of allelic richness was also assessed by one-way ANOVA on shoot density performed at each genotypic richness level individually, both on data of resistance collected right after mortality linked to the algal bloom and at the end of the resilience survey.
Second, food plant diversity, and in particular the regional species richness of figs as keystone fruit trees during times of food shortage, has been linked to the diversity of frugivores [7], [8].
Data richness maps for the six categories of human uses show that all, except shipping and transport, are also closely linked to the shoreline and continental shelf.
Precipitation, primary productivity, and herbivore biomass are linked to ungulate richness (the number of species) in African ecosystems.
Temperature and productivity can each vary greatly over large spatial scales and both have been linked to species richness gradients in the Atlantic [65] and Indo-Pacific [66].
