The conservation status of the world’s freshwater molluscs

With the biodiversity crisis continuing unchecked, we need to establish levels and drivers of extinction risk, and reassessments over time, to effectively allocate conservation resources and track

Assessing conservation status and trends for the world’s butterflies: the Sampled Red List Index approach

This work describes ongoing efforts to incorporate butterflies into the Red List Index process and illustrates the process and the challenges (particularly taxonomic issues and issues of data deficiency) using a variety of case studies.

Odonata species of special concern for Oklahoma, USA

Nine species are critically imperiled in the Great Plains state of Oklahoma in the central USA and require immediate conservation attention, initially at the level of intensive surveys to delineate the full extent of the geographic range in the state and to determine the population size and habitat needs.

Multiple drivers of decline in the global status of freshwater crayfish (Decapoda: Astacidea)

This study evaluated the extinction risk of the world's 590 freshwater crayfish species using the IUCN Categories and Criteria and found 32% of all species are threatened with extinction.

Worldwide decline of the entomofauna: A review of its drivers

Monitoring Extinction Risk and Threats of the World’s Fishes based on the Sampled Red List Index

Global biodiversity targets require us to identify species at risk of extinction and quantify status and trends of biodiversity. The Red List Index (RLI) tracks trends in the conservation status of

The Impact of Conservation on the Status of the World’s Vertebrates

Though the threat of extinction is increasing, overall declines would have been worse in the absence of conservation, and current conservation efforts remain insufficient to offset the main drivers of biodiversity loss in these groups.

An overview of Neotropical arthropod conservation efforts using risk assessment lists

Neotropical efforts for arthropod conservation are still insufficient. Some species from the Neotropical region have been assessed by the IUCN Red List criteria (IRL), while others have been assessed



Freshwater crabs and the biodiversity crisis: Importance, threats, status, and conservation challenges

Toward monitoring global biodiversity

Implementing the development and implementation of the IUCN Red List Index with a new sampled approach will greatly increase understanding of the status of the world's biodiversity by 2010, enabling the first assessment of a number of key groups.

Global diversity of dragonflies (Odonata) in freshwater

Diversity is discussed, the biogeography of dragonflies in the different biogeographical regions is summarised and the total number of species and genera per family perBiogeographical region is given.

Identification of dragonflies (Odonata) as indicators of general species richness in boreal forest lakes

Dragonfly species richness appears to be positively associated with species richness of vascular plants, and nestedness matrices are proposed to be a good selecting tool for indicator species, particularly in groups where the biology of the species is not well known.

Quantification of Extinction Risk: IUCN's System for Classifying Threatened Species

  • Environmental Science
    Conservation biology : the journal of the Society for Conservation Biology
  • 2008
The process and the technical background to the IUCN Red List system is described, which was designed to measure the symptoms of extinction risk, and uses 5 independent criteria relating to aspects of population loss and decline of range size.

Critical species of Odonata in Europe

It is believed that future conservation efforts should focus on the most valuable and threatened habitats in each sub-region, and active conservation measures could be implemented on a European scale, provided that research will establish a solid ground for such measures.

Dragonfly Assemblages in Arid Tropical Environments: A Case Study from Western Namibia

It is proposed that dragonflies will have a high indicator potential for threatened freshwater wetlands in such areas and may also serve as an indication of the sustainable use of water resources including evaluating measures to rehabilitate environments.

The Tropical Biodiversity Data Gap: Addressing Disparity in Global Monitoring

This work examines the coverage of biodiversity data using four global biodiversity datasets, and looks at how effective current efforts are at addressing this discrepancy, and what countries might be able to do in time for 2010 and beyond.

Measuring Global Trends in the Status of Biodiversity: Red List Indices for Birds

A method for producing indices based on the IUCN Red List to chart the overall threat status (projected relative extinction risk) of all the world's bird species from 1988 to 2004 is presented.

Global mammal distributions, biodiversity hotspots, and conservation

A global examination of distributions of all nonmarine mammals to determine patterns of species richness, endemism, and endangerment, and to evaluate the degree of congruence among hotspots of these three measures of diversity in mammals found it necessary to assign global conservation priorities based on hotspots.
