Languages are being lost at rates exceeding the global loss of biodiversity. With the extinction of a language we lose irreplaceable dimensions of culture and the insight it provides on human history and the evolution of linguistic diversity. When setting conservation goals, biologists give higher priority to species likely to go extinct. Recent methods now integrate information on species evolutionary relationships to prioritize the conservation of those with a few close relatives. Advances in… Expand

TLDR
It was found that species restricted to islands were more original than continental species and, although functionally and evolutionary original species were dissimilar, many occurred on similar territories so that regional conservation strategies may allow to conserve these distinct forms. Expand

Endangered languages: On endangered languages and the importance of linguistic diversity
Introduction During the coming century, according to some informed estimates, 3,000 of the existing 6,000 languages will perish and another 2,400 will come near to extinction. This leaves just 600Expand
Ranking Mammal Species for Conservation and the Loss of Both Phylogenetic and Trait Diversity
TLDR
The results suggest that, as advertised, EDGE mammal species contribute evolutionary history to the evolutionary tree of mammals non-randomly, and EDGE-style rankings among endangered species can also capture important trait diversity. Expand
Prioritizing Populations for Conservation Using Phylogenetic Networks
TLDR
This paper constructs phylogenetic networks and scores each population by its relative genetic distinctiveness, and suggests they be added to the assortment of tools available to wildlife managers for allocating effort among threatened populations. Expand
Parallel extinction risk and global distribution of languages and species
TLDR
It is shown, by applying internationally agreed criteria for classifying species extinction risk, that languages are more threatened than birds or mammals. Expand
Mammals on the EDGE: Conservation Priorities Based on Threat and Phylogeny
TLDR
A simple index is defined that measures the contribution made by different species to phylogenetic diversity and how the index might contribute towards species-based conservation priorities and suggests that global conservation priorities may have to be reassessed in order to prevent a disproportionately large amount of mammalian evolutionary history becoming extinct in the near future. Expand
Measuring Evolutionary Isolation for Conservation
TLDR
It is suggested that all future developments are compared to the current published set of metrics, and scripts to aid such comparisons are offered. Expand
Evolutionary distinctiveness, threat status, and ecological oddity in primates.
TLDR
Although primates with a high EDGE score had characteristics that made them seem odd, they did not seem to express more ancestral characteristics than expected, suggesting that sets of primate species with highEDGE scores will collectively capture a broader than expected range of the biology of the clade.

TLDR
A system of prioritization that incorporates both threat status and genetic information and applied to 9546 species of birds worldwide showed that ranking species by expected loss of genetic information may help preserve bird evolutionary history by upgrading those threatened species with fewer close relatives.

What to protect?—Systematics and the agony of choice
TLDR
It is concluded that two basic rounds of analysis are required: recognition of global priority areas by taxic diversity techniques; and, within any such area, analysis without taxic weighting to identify a network of reserves to contain all local taxa and ecosystems. Expand
Global distribution and drivers of language extinction risk
TLDR
It is shown that both small range and speaker population sizes are associated with rapid declines in speaker numbers, causing 25% of existing languages to be threatened based on criteria used for species. Expand
