In the literature, the terms species richness and species diversity are sometimes used interchangeably. We suggest that at the very least, authors should define what they mean by either term. Of the many species diversity indices used in the literature, the Shannon Index is perhaps most commonly used. On some occasions it is called the Shannon‐Wiener Index and on other occasions it is called the Shannon‐Weaver Index. We suggest an explanation for this dual use of terms and in so doing we offer… 

Shannon–Wiener Index

Measuring species diversity for conservation biology: incorpo - rating social and ecological importance of species

The proposed Importance-Diversity Index incorporates an importance weight to each species of organisms found in an ecosystem that is derived from four main domains deemed important in conservation biology, namely species endemicity, ecological role, functional role in the ecosystem, and risk status of the species.

Simpson diversity and the Shannon–Wiener index as special cases of a generalized entropy

A link is noted between a common family of diversity indices and non-additive statistical mechanics that makes the Shannon index and the Simpson diversity (or Gini coefficient) special cases of a more general index.

MORE ON SAMPLING FOR RICHNESS AND DIVERSITY IN ARCHAEOBIOLOGICAL ASSEMBLAGES

Some fundamental issues associated with the sampling to redundancy method are discussed, and some recommendations for using this method to evaluate richness and diversity of archaeobiological assemblages are made.

Avoiding erroneous citations in ecological research: read before you apply

This study used the Web of Science database to examine cases where papers published from 1990 to 2015 mislabelled the Shannon–Wiener index, and provides detailed insights into causes potentially affecting use of the wrong name ‘Weaver’ instead of the correct ‘Wiener’.

Modification of Shannon-Wiener Diversity Index towards Quantitative Estimation of Environmental Wellness and Biodiversity Levels under a Non-comparative Scenario

Shannon-Wiener diversity index has been used extensively in environmental studies to estimate the species richness and abundance of ecosystems. The use of the index works very well under comparative

Disentangling the Information in Species Interaction Networks

This work leverages the little-known balance equation to decompose the network information into three components describing the species abundance, specificity, and redundancy, revealing that there exists a fundamental trade-off between these components.

Floristic composition, structure and tree diversity of an amazon forest in Peru

The Amazonian forests of Peru are among the most diverse and disturbed by anthropic activities on the planet, today there are still gaps on the composition of the communities and their inter-specific

Choosing Plant Diversity Metrics: A Tallgrass Prairie Case Study

Diversity metrics are used to compare sites and to track trends within sites. Many metrics have been proposed, from simple species counts to complex indices like the Floristic Quality Index (FQI).

The species richness of ecosystems can remain stable over time, despite changes in species composition and changes in the dominant plant species. While this pattern of stability is known to occur

Using pitfall traps to investigate species diversity

The paper describes a simple procedure for investigating the diversity of arthropods present in a terrestrial habitat and two commonly-used Indexes of diversity are described, and a computer program listing which calculates these indexes is provided.

Scale and species richness: towards a general, hierarchical theory of species diversity

The case is articulated for a top-down approach to theory building, in which scale is addressed explicitly and in which different response variables are clearly distinguished, to articulate the case for a general theory of diversity that must necessarily cover many disparate phenomena, at various scales of analysis.

We studied the patterns of species richness and range–size rarity (as a measure of endemism) of two plant groups (Pteridophyta, Bromeliaceae) and birds along two gradients of elevation, humidity and

A considerable portion of the paper describes and illustrates a method for expressing the criteria of distortionless transmission in terms of the steady-state characteristics of the system, and of the minimum frequency range required for transmission at a given speed of signaling.

In considering methods for increasing the speed of telegraph circuits, the engineer is confronted by the problem of transmitting over a circuit the maximum amount of intelligence using a given
