Relationships Among Indices Suggest that Richness Is an Incomplete Surrogate for Grassland Biodiversity (2005, background): “…variation within grassland sites, or to estimate diversity in a more comprehensive manner, measures based on relative abundance, in addition to richness, are much better than richness alone (Collins 1990, Buzas and Hayek 1996, Chapin et al. 2000, Purvis and Hector 2000, Stirling and Wilsey 2001).”
Developing indicators for European birds (2005, background): “Of course, biodiversity is a multifaceted term, defined as the sum total of all biotic variation from the level of genes to ecosystems (Purvis & Hector 2000).”
Difficult decisions: Strategies for conservation prioritization when taxonomic, phylogenetic and functional diversity are not spatially congruent (2018, background): “It is increasingly recognized that biodiversity has multiple components, including diversity in form and function (often measured from traits), diversity in the number of species and their abundances, and diversity in species genetic composition and evolutionary histories, with each offering potenti”
Intensive agriculture reduces soil biodiversity across Europe (2015, background): “Understanding the consequences of agricultural land use on soil biodiversity requires taking into account that biodiversity is a multidimensional concept (Purvis & Hector, 2000).”
Revisiting Remane’s concept: evidence for high plankton diversity and a protistan species maximum in the horohalinicum of the Baltic Sea (2011, result): “…diversity metric for our analysis because (1) species number is the most commonly considered facet and the simplest measure of biodiversity (Purvis & Hector 2000), and (2) this choice of unit provides the best comparability of our results with the reference data published by Remane (1934).”
Changes in four complementary facets of fish diversity in a tropical coastal lagoon after 18 years: a functional interpretation (2005, background): “It is therefore helpful to separate biodiversity into several independent facets which can be quantified (Purvis & Hector 2000).”
Functional groups of lagoon fish species in Languedoc Roussillon, southern France (2004, background): “It is not easy to ‘capture’ this measure as a single number (Chapin et al., 2000; Purvis & Hector, 2000).”
Tree Diversity in Western Kenya: Using Profiles to Characterise Richness and Evenness (2006, background): “…diversity profile can be decomposed as: Ha ¼ lnSþ lnEa;0 This decomposition has the attractive feature in showing mathematically that diversity combines information on species richness and evenness, which conforms to the definition of diversity (Magurran 1988; Purvis and Hector 2000; Shaw 2003).”
Scale and species richness: towards a general, hierarchical theory of species diversity (2001, background): “…Oksanen, 1996), and whereas the relationships being revealed by work at the macroscale are generally consistent, at local scales of analysis, climatic controls are less evident as other factors that exhibit greater heterogeneity at these scales kick in with their signal (cf. Purvis & Hector, 2000).”
The release of genetically modified crops into the environment. Part II. Overview of ecological risk assessment. (2003, background): “Biodiversity cannot be reduced to a single number, despite the explicit wishes of policy makers (Purvis and Hector, 2000).”
Species diversity and community structure in neotropical fruit‐feeding butterflies (2001, background): “…has focused on why there are so many tropical species studies of species diversity are of vital importance and how they are maintained in the communities for understanding biological communities and their they occupy (Preston, 1948, 1980; Dobzhansky, 1950; conservation (Purvis & Hector, 2000).”
Species richness and evenness respond in a different manner to propagule density in developing prairie microcosm communities (2007, positive): “Species diversity has two basic components: richness, or number of species in a given area, and evenness, or how relative abundance or biomass is distributed among species (Huston 1994; Purvis and Hector 2000; Magurran 2004).”
Fungal endophytes in xylem of healthy chilean trees and their possible role in early wood decay (2008, background): “Despite efforts, the full range of ecological functions of endophytic fungi of woody plants is poorly understood but it is likely to be correlated with species diversity (Purvis and Hector, 2000; Hendry et al., 2002).”
