TLDR
In this article, a quantitative and qualitative assessment of the international scientific literature of the past ten years indicates major differences in the definitions and use of the term biodiversity in scientific articles from year to year.Abstract:
A quantitative and qualitative assessment of the international scientific literature of the past ten years indicates major differences in the definitions and use of the term biodiversity. This in part reflects a steady increase in the number of occurrences of the term in the titles of scientific articles from year to year, as shown by a search of various online literature databases.read more

Biodiversity indicators: the choice of values and measures
Peter Duelli,Martin K. Obrist +1 more
TL;DR: For biodiversity evaluation in agricultural landscapes, three indices are proposed, each consisting of a basket of concordant indicators that represent the three value systems “conservation”, “ecology” and “biological control”: protection, resilience, ecosystem functioning, based on species diversity.

The significance of different indices for stand structure and diversity in forests
Markus Neumann,Franz Starlinger +1 more
TL;DR: Data from the so-called Level II Plots which were established within the frame of the Pan-European Programme for Intensive and Continuos Monitoring of Forest Ecosystems were used to quantify stand structure and species diversity by means of different indices show that there exist only few and weak correlations between species diversity of different vegetation layers, and between plant species diversity and diversity of stand structure, while among all the indices ofStand structure a correlation exists.

Forest biodiversity and its assessment by remote sensing
John L. Innes,Barbara Koch +1 more
TL;DR: In this article, the authors present a survey of the use of remote sensing techniques for the assessment of forest biodiversity and its structural attributes, such as the relative proportion of matrix and patches and their physical arrangement.

Tree microhabitat structures as indicators of biodiversity in Douglas-fir forests of different stand ages and management histories in the Pacific Northwest, U.S.A.
Alexa K. Michel,Susanne Winter +1 more
TL;DR: In this article, microhabitat structures in Douglas-fir ( Pseudotsuga menziesii ) forests were defined and their frequency and abundance in natural stands and stands of varying active management histories and stand ages was compared.

Testing the spectral variation hypothesis by using satellite multispectral images
TL;DR: In this article, a test of the spectral variation hypothesis (SVH) was performed using multispectral high-resolution satellite data, by comparing the relationship between the spectral heterogeneity and species richness in plots of different size in a complex wetland ecosystem, the “Montepulciano Lake”, Central Italy.

The Nonconcept of Species Diversity: A Critique and Alternative Parameters.
TL;DR: It is suggested that species diversity has become a meaningless concept, that the term be abandoned, and that ecologists take a more critical approach to species-number relations and rely less on information theoretic and other analogies.
Journal ArticleDOI
Convention on Biological Diversity
TL;DR: In this article, the authors propose case studies on various topics to identify management practices, technologies and policies that promote the positive and mitigate the negative impacts of agriculture on biodiversity, and enhance productivity and the capacity to sustain livelihoods.
Journal ArticleDOI
Global biodiversity assessment
TL;DR: The Global Biodiversity Assessment (GBA) project as mentioned in this paper has been used to assess the global biodiversity of plants and its relationships with its components. But it has not yet been used for the assessment of the global ecosystem.
