Species Richness, Taxonomic Distinctness and Environmental Influences on Euphausiid Zoogeography in the Indian Ocean
Although two thirds of the world’s euphausiid species occur in the Indian Ocean, environmental factors influencing patterns in their diversity across this atypical ocean basin are poorly known. Distribution data for 56 species of euphausiids were extracted from existing literature and, using a geographic information system, spatially-explicit layers of species richness and average taxonomic dis...
متن کاملTaxonomic distinctness and diversity measures: responses in marine fish communities
In a recent paper Warwick & Clarke (1995: Mar Ecol Prog Ser 129:301-305) introduced 2 new measures of community diversity, A and A' These measures dlffer from more conventional d~ver sity indices by incorporating the taxonomic relatedness of species into their calculation. In this paper we compare temporal trends in A and A' with more conventional diversity measures for the demersal fish commun...
متن کاملDiversity Assessment of Lotic Macroalgal Flora by the Application of Taxonomic Distinctness Index
The main aim of this study was to assess the diversity of four stream algal divisions (Cyanobacteria, Chlorophyta, Ochrophyta and Rhodophyta) by comparing results obtained with taxonomic distinctness index and diversity patterns of previous studies. The data were obtained from a study made in 1000 stream segments in North American biomes. The taxonomic arrangement of the taxa was created from s...
متن کاملcomparing the environmental impact assessment methods using analytical taxonomic analysis
further to emerging the environmental protection thoughts in the 1970's, most of the governments in the developed countries have been faced with social pressures for taking actions in order to stop the degradation in the environment and the quality of life. in response to such a societal desire, those governments have approved the requirement of environmental impact statement for the proje...
متن کاملTaxonomic distinctness and conservation of a new high biodiversity subterranean area in Brazil.
Subterranean environments, even though they do not possess a primary production (photosynthesis), may present high biodiversity, faunistic originality, endemism, phylogenetic isolations and unique ecological and/or evolution events, in addition to rare taxa. Studies investigating the biological diversity in Neotropical caves are relatively rare and recent, and most of them have been conducted i...
