Those indices are evaluating the richness, evenness, fragmentation and shape of the landscape patch types.
Specifically, we used total species richness, mean CC, and FQI to quantify differences in ground layer vegetation between burned and unburned sites, determine if relationships between richness and mean CC were consistent at local and landscape-scales, and evaluate the influence of richness and mean CC on FQI values using empirical data.
We evaluate the distribution of species richness and threat among freshwater species, identify centres of freshwater endemism and, using a heuristic approach, highlight key gaps in determining how freshwater conservation actions can be targeted at the most pressing cases.
A nestedness analysis and spatial autocorrelations were used to evaluate the spatial patterns of richness.
We used two long-term datasets to evaluate the effects of shrub invasion on richness and dynamics of subordinate species in Chihuahuan desert plant communities.
We used Akaike's Information Criterion AICC) to evaluate the effectiveness of 13 a priori models in predicting total amphibian species richness, anuran richness, caudate richness, and the presence of individual species in woodlots.
The aims of this work were to evaluate the composition, abundance and richness of insect assemblages in different soybean-weed (Artemisia annua and Chenopodium album -herbivory combinalbum -herbivorytermine the relationship between insecombinationses and volatole signals emittedeterminedifferentheombinations.
Here, we preliminarily evaluated the paleolatitudinal richness gradient of vascular plants for the Eocene (56-33.9 million years ago) and Oligocene (33.9-23 million years ago) epochs of North America north of Mexico using 201 fossil floras.
In each environment, performance is evaluated on a scale relative to the richness of that environment.
In this context, the objectives of this work were i) to evaluate the composition, abundance and richness of floral visitor assemblages in different coriander crop genotypes and sowing dates and ii) to determine the relationship between insect assemblages and volatile signals emitted by the different coriander genotypes.
