Entropy and the species accumulation curve: a novel entropy estimator via discovery rates of new species (2013, methodology): “Shannon entropy was adopted by ecologists as a diversity measure in the 1950s (MacArthur 1955, 1965; Margalef 1958); see Ulanowicz (2001) for the early history of information theory in ecology.”
Biodiversity of nematode assemblages from deep-sea sediments of the Atacama Slope and Trench (South Pacific Ocean) (2003, methodology): “Species richness (SR) was estimated from Margalef’s formula as SR 1⁄4 ðS 1Þ=ln N ; where S is the number of species and N the number of individuals in a sample (Margalef, 1958) and the same formula was used to estimate genus richness, based on the number of genera encountered in each sample.”
Function of male song in the greater white-lined bat, Saccopteryx bilineata (2004, positive): “To measure repertoire diversity, we calculated a ShannoneWiener index for each bat using the 21 element categories (Margalef 1958).”
Litterfall Dynamics Under Different Tropical Forest Restoration Strategies in Costa Rica (2011, methodology): “To determine the actual diversity of litter, we estimated a canopy species diversity index (d) per plot according to Margalef diversity index (Margalef 1958): d = [(S 1)/ln N]; where S is the number of species and N is the total number of individuals.”
A history of graph entropy measures (2011, background): “For a discussion of other information-theoretic measures in this context, see [47,89,90].”
Role of denitrifier diversity in rates of nitrous oxide consumption in a terrestrial ecosystem (2001, methodology): “We dissected this diversity measurement by calculating taxonomic richness (Margalef, 1958) and evenness (Pielou, 1966).”
Tag-encoded pyrosequencing analysis of bacterial diversity in a single soil type as affected by management and land use (2008, background): “…length to enable extrapolations that estimate bacterial diversity based on its two components: (1) the total number of species present (species richness or abundance), and (2) the distribution of individuals among those species (species evenness or equitability; Margalef, 1958; Kennedy, 1999).”
Mangrove diversity enhances plant biomass production and carbon storage in Hainan island, China (2021, methodology): “For each plot and each transect, the number of spe - cies and trees was recorded to calculate the Shannon diversity index (Shannon & Weaver, 1998), Simpson diversity index (Simpson, 1949) and species richness (Margalef, 1957).”
Endophytic fungi harbored in Cannabis sativa L.: diversity and potential as biocontrol agents against host plant-specific phytopathogens (2013, methodology): “…richness (D mg ) were calculated (Fisher et al. 1943; Hoffman et al. 2008; Lambshead et al. 1983; Simpson 1949; Suryanarayanan and Kumaresan 2000; Margalef 1958; Tao et al. 2008) using the following equations, re- spectively: a ¼ N 1 À x ð Þ x Where, x was calculated by S N ¼ 1 À x ð Þ x ln 1 1…”
The Influence of the Spatial Structure of Hydromacrophytes and Differentiating Habitat on the Structure of Rotifer and Cladoceran Communities (2006, methodology): “To define the species diversity of zooplankton inhabiting different types of water vegetation the Shannon-Weaver index was applied (Margalef, 1957).”
