The term ‘biodiversity’ is a simple contraction of ‘biological diversity’, and at first sight the concept is simple too: biodiversity is the sum total of all biotic variation from the level of genes to ecosystems. The challenge comes in measuring such a broad concept in ways that are useful. We show that, although biodiversity can never be fully captured by a single number, study of particular facets has led to rapid, exciting and sometimes alarming discoveries. Phylogenetic and temporal… 
Modern Taxonomy and Field Work Biodiversity Dr
The word biodiversity is used to explain the variety of life on Earth, and is considered at different levels of biological organization including genes, species and ecosystems. Biodiversity is most
Short communication Biodiversity: luxury or necessity?
Biodiversity—a contraction of biological diversity— appears at first sight to be a simple concept, i.e. the total sum of biotic variation, ranging from the genetic level to ecosystems. On closer
How many dimensions of biodiversity do we need
ow many dimensions of biodiversity do we need ? lga
Biodiversity is a measure of the total difference within a biological system. It is understood to arise at genetic, species and multiple levels of community organisation, hence is multidimensional in
The need for the incorporation of phylogeny in the measurement of biological diversity, with special reference to ecosystem functioning research

TLDR
A specific case study is presented of how this added emphasis on phylogeny‐based biodiversity measurement can influence the way in which research is directed and hypotheses are generated.
The Three Dimensions of Species Diversity
TLDR
This paper proposes to express species diversity of communities as their position in a three-dimensional volume along the axes of richness, abundance, and evenness, and believes that expressing species diversity as a volume is biologically intuitive, easy to interpret numerically and ecologically, and very useful in the assessment and management of biodiversity at the species level.
An Overview of Biodiversity—Estimating the Scale
The term "biological diversity" was introduced by Elliot Norse and colleagues to define diversity at three levels of complexity: (i) genetic (intraspecies diversity), (ii) species (numbers of

TLDR
Only by studying biodiversity in the context of evolution, natural history and ecology the authors can understand values and gaps of past theories trying to provide a broader understanding of life on Earth towards a Unified Theory of Biodiversity.

Microbial diversity and the “lower-limit” problem of biodiversity
TLDR
This paper investigates how microbial diversity faces two of the classical issues encountered by the concept of “biodiversity”: the issues of defining the units of biodiversity and of choosing a mathematical measure of diversity.

TLDR
An alternative published model for relating features to a particular form of phylogenetic pattern is considered, and shown to make unwarranted assumptions, and a possible alternative definition of the underlying units of diversity is examined.

TLDR
A mechanistic model of a spatially structured ecosystem in which plants compete for a limiting soil nutrient shows that plant species richness does not necessarily enhance ecosystem processes, but it identifies two types of factors that could generate such an effect: complementarity among species in the space they occupy below ground and positive correlation between mean resource-use intensity and diversity.
Biodiversity and stability in grasslands
ONE of the ecological tenets justifying conservation of biodiversity is that diversity begets stability. Impacts of biodiversity on population dynamics and ecosystem functioning have long been
Biodiversity enhances ecosystem reliability
TLDR
It is found that as the number of species per functional group increased, replicate communities were more consistent in biomass and density measures, suggesting that redundancy (in the sense of having multiple species perfunctional group) is a valuable commodity, and that the provision of adequate redundancy may be one reason for preserving biodiversity.

TLDR
This loss of biodiversity, at the very time when the value of biotic resources is becoming widely recognized, has made it strikingly clear that current strategies for conservation are failing dismally.
Estimating terrestrial biodiversity through extrapolation.
TLDR
The importance of using 'reference' sites to assess the true richness and composition of species assemblages, to measure ecologically significant ratios between unrelated taxa, toMeasure taxon/sub-taxon (hierarchical) ratios, and to 'calibrate' standardized sampling methods is discussed.
Biodiversity regulates ecosystem predictability
TLDR
By manipulating biodiversity in aquatic microbial communities, it is shown that one process, ecosystem respiration, becomes more predictable as biodiversity increases, and analysis of similar patterns extracted from other studies indicates that biodiversity also enhances predictability in terrestrial ecosystems.
