Measuring Data (2022, background): “Records of measurements quantifying how diverse a sample is are more recent, appearing over the last century in subﬁelds of biology, notably for the purpose of measuring ecological diversity (cf. (Harris, 1916; Magurran, 1988)).”
A general framework for analysing diversity in science, technology and society (2007, background): “concepts have been particularly thoroughly investigated (Magurran 1988).”
The effect of plant richness and urban garden structure on bird species richness, diversity and community structure (2014, methodology): “(2) Bird species diversity, which can be calculated y using indices such as Shannon index that takes into account oth the number of species present and their relative abundance n the community (Magurran, 1988).”
Nematodes as soil indicators: functional and biodiversity aspects (2003, background): “There must be concern about the validity of divisions and weightings applied to nematodes [mathematical debate about the most suitable bases for, or form of, indices is discussed by Magurran (1988) and Colinvaux (1993)].”
Effects of phosphorus enrichment and grazing snails on modern stromatolitic microbial communities (2005, methodology): “relative proportion (pi) of the total community contributed by particular ribotypes ( Magurran, 1988 ).”
Reduction of a native fish fauna by alien species: an example from Brazilian freshwater tropical lakes (2004, methodology): “Shannon and Berger–Parker diversity indices were calculated for each sampling unit ( Magurran 1988 ).”
Fungi in decayed roots of conifer seedlings in forest nurseries, afforested clear‐cuts and abandoned farmland (2006, unknown): “Fungal community structures were compared by calculating qualitative Sorenson similarity indices (SS) (Magurran, 1988).”
Monitoring arthropods in a tropical landscape: relative effects of sampling methods and habitat types on trap catches (2009, methodology): “First, we compared the abundance and diversity of the material collected by the four sampling methods with a series of standard statistics and curves routinely used in ecology (Magurran 1988; Colwell 2005): Kruskal–Wallis tests, coefficient of variation, Coleman rarefaction, nonparametric Chao1 esti”
Odonates as Indicators of Shallow Lake Restoration by Liming: Comparing Adult and Larval Responses (2004, methodology): “To assess differences in gross assemblage structure, we plotted rank-abundance curves on relative abundances, and also calculated diversity indices for the two lake groups (Shannon Weaver function, evenness, and Berger Parker index; Magurran 1988).”
Decreases in organic C reserves in soils can reduce the catabolic diversity of soil microbial communities (2000, methodology): “Although it is generally accepted that diversity is composed of two components (richness and evenness, Magurran, 1988), we are constrained to measuring catabolic evenness because it is impractical to measure the immense richness of microbial catabolic functions in soils.”
Feeding Partitioning among Tuna Taken in Surface and Mid-water Layers: The Case of Yellowfin ( Thunnus albacares ) and Bigeye ( T. obesus ) in the Western Tropical Indian Ocean (2004, background): “noticed by Roger (1994b) and Ménard and Marchal (2003), once a prey concentration of one target species is detected, tuna can feed on this concentration until satiation.”
The Little Fire ant Wasmannia auropunctata (Roger) (Hymenoptera: Formicidae) as a Diversity Indicator of Ants in Tropical Dry Forest Fragments of Colombia (2003, methodology): “Shannon and Weaver diversity index (“Shannon”: H ) (Magurran 1988) was calculated with the program ESTIMATES 5.0.1 (Colwell 1997) for comparison purposes.”
ASSEMBLY HISTORY INTERACTS WITH ECOSYSTEM SIZE TO INFLUENCE SPECIES DIVERSITY (2004, background): “Moreover, species diversity is not just species richness, but also encompasses species evenness, how the total abundance or biomass of a community is distributed among species (Magurran 1988).”
Restoration of Prairie Community Structure and Ecosystem Function in an Abandoned Hayfield: A Sowing Experiment (2007, methodology): “We calculated four measures of plant diversity: species richness (S), Shannon diversity (H9; Magurran 1988), community evenness (H9/HMax; Magurran 1988), and functional guild diversity (H9FG).”
