A practical strategy for analysing multispecies distribution patterns
A strategy is presented for analysing marine biological survey data and relating the biotic patterns to environmental data to avoid circular argument, and the 4 major station groups and species groups are related to one another in terms of morphological adaptation to the habitat. Expand
A taxonomic distinctness index and its statistical properties
For biological community data (species-by-sample abundance matrices), Warwick & Clarke (1995) defined two biodiversity indices, capturing the structure not only of the distribution of abundancesExpand
A further biodiversity index applicable to species lists: variation in taxonomic distinctness
The combination of Δ+ and Λ+ is seen to provide a statistically robust summary of taxonomic (or phylogenetic) relatedness patterns within an assemblage, which has the potential to be applied to a wide range of historical data in the form of simple species lists. Expand
New \'biodiversity\' measures reveal a decrease in taxonomic distinctness with increasing stress
A coral reef comprised of calcareous and non-calcareous organisms can be shown to act as a sink for atmospheric CO2 when excess (= net) production is high and CaC03 precipitation is low and this prediction is confirmed by the only existing measurement of air-sea CO2 flux in a coral reef system.

Similarity-based testing for community pattern: the two-way layout with no replication
A limited way forward is provided for hypothesis testing in the absence of replicates of a two-way layoutwithout replication, with data from two experimental and two field studies involving meiofaunal communities from soft-sediment and macro-algal habitats. Expand
A new method for detecting pollution effects on marine macrobenthic communities
A method is described by which the pollution status of a marine macrobenthic community may be assessed without reference to a temporal or spatial series of control samples, based onoretical considerations suggest that the distribution of numbers of individuals among species should behave differently when influenced by pollution-induced disturbance. Expand
Taxonomic distinctness and environmental assessment
The objectives of this paper are to test the performance of the taxonomic distinctness index, δ+, in a number of environmental impact scenarios, to examine its relationship with functional diversityExpand
Detection Of Initial Effects Of Pollution On Marine Benthos - An Example From The Ekofisk And Eldfisk Oilfields North-Sea
The first recorded changes in benthic communities in response to oil were increased abundance patterns of some species and changes in the presence and absence patterns of rare species, with species being mostly present in one site group and mostly absent in another site group. Expand
Quantifying structural redundancy in ecological communities
The level of structural redundancy may be an indirect measure of the resilience or compensation potential within an assemblage by extracting a series of subsets of species that closely matches that for the whole community. Expand
