Development Of An Avian Index Of Biological Integrity For Kentucky Wetlands
… in wetland habitats. I developed an avian index of biological integrity (IBI) for wetlands of Kentucky as an intensive assessment method to supplement an existing rapid assessment method used in regulatory programs. Birds are useful indicators because they are sensitive to environmental …

Parametric, Non-Parametric And Statistical Modeling Of Stony Coral Reef Data
… obtained from the jackknife procedure for the Shannon-Wiener diversity index used in previous studies. We investigate a new and more effective approach to estimating the Shannon-Wiener and Simpson's diversity index. In chapter four, we develop the best possible estimate of the probability …

Assessing Subterranean Arthropod Diversity through COI Barcoding in Two Ecoregions of Southwestern Virginia, USA
… this, fundamental information about species diversity in these communities remains unknown, and their taxonomic composition and ecological diversity have scarcely been assessed. Subterranean pitfall traps are a commonly used method for sampling endogean and hypogean soil habitats in Europe …

Biodiversity patterns in False Bay: an assessment using underwater cameras
Understanding how marine biodiversity is distributed, and what drives these patterns, relies on good descriptions of marine ecosystems. This information should inform the protection of biodiversity and guide its management. Relationships between marine landscapes and biodiversity therefore need to …

Large-scale habitat relationships of neotropical migratory birds
… of community performance including species diversity, species richness, species equitability, and indices of relative abundance were calculated for each site. I determined the large-scale habitat characteristics of each site by analyzing coverages of each site from Quantico’s GIS database …

The roles of exotic and native tree species in preventing desertification and enhancing degraded land restoration in the north east of Libya. Reciprocal effects of environmental factors and plantation forestry on each other, assessed by observations on growth and reproductive success of relevant tree species, and environmental factors analysed using multivariate statistics.
… of afforestation on the promotion of biological diversity have been investigated using the Shannon-Wiener diversity index. The effects of tree species on soil depth have also been investigated. Multivariate statistical analyses of site, species and environmental data, using both cluster analyses …

Multimetric assessment of freshwater macroinvertebrate communities in Flanders, Belgium
… Ratio (EQR) showing relative proportion of the index compared to the reference conditions. This EQR ranges from zero to one, respectively corresponding to a bad and a very good ecological status. This interval is divided into five classes reflecting bad, poor, moderate, good and high ecological …
