In Montes Azules the highest functional richness values were recorded for dung beetle communities in continuous rainforest and in rainforest fragments, while in pasture communities a loss of functional diversity was evident.
Both the Chao 1 and the ACE estimators pinpointed SNC as the habitat with the highest estimated richness values (1,240 and 2,115, respectively; Table 2).
Individual based rarefaction curves suggest that, for equal sample size, expected species richness in rural environmental types is slightly lower than in other environmental types with higher species richness values (fig. 2).
The highest species richness value (1.42 species stand 1) is recorded in the coastal desert.
In all simulated species richness scenarios, a survey directed towards those localities that were previously recognized as having a higher species richness value is not recommended if the aim is to recover the true geographical pattern of species richness in a given territory.
Thus, for a group with a highest species richness value of 100, a cell with 50 species would be normalized to 0.5, 40 to 0.4, and so on.
Three hundred and twelve Important Plant Areas (IPAs) have been identified in Italy using a grid-based ranking system to pinpoint areas of high richness and conservation value, alongside the more frequently used expert-based selection of sites.
The analysis of the distribution of patterns of richness along the Humboldt Current system observed in the OBIS database showed three zones of high richness (Figure 10) with the highest values found in the Strait of Magellan.
In other words, marine species richness has a high potential to be underestimated, and species richness values potentially increase more rapidly per unit of investigative effort.
This is indicated by the fact that the percent of area within protected areas with richness values above 600 is higher than the proportion of the country with this same richness values (Figure 3i,j).
