Both landscape heterogeneity and species richness were calculated using two spatial analytical unit approaches: eco-geographic vs. arbitrary (i.e., watersheds vs. square windows of different sizes 20 × 20 km, 50 × 50 km, 100 × 100 km).
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.
We stopped recruitment when we reached 30-35 interviews, owing to the depth and duration of interviews, richness of data, and complexity of the analytical task.
The IBI was developed using bird assemblages found in these patches, and its performance was compared with analytical approaches commonly used in environmental assessment, such as general richness and Shannon's diversity index.
We used a novel statistical design to maximize parsimony and analytical power in an experiment with three levels of species richness (seven mono-culture, 21 di-culture, and seven tri-culture treatments).
The results show both the richness of the CSF proteome and the power of current analytical methods to define its changes in relation to alterations in disease state.
We predicted species richness on the basis of landscape heterogeneity by fitting separate linear models for each spatial analytical unit approach.
We assessed the relationship between terrestrial vertebrate species richness (total and taxonomic) and structural landscape heterogeneity, testing the impact of using different spatial analytical units in three mountain systems in Spain.
The study offers a comparative analytical assessment of these diverse approaches and lays out a nuanced understanding of urban livability that draws on the richness and diversity embedded in design, planning, and current ranking tools.
It sacrifices nothing in richness.
