The languages are disappearing at an alarming rate; half of 7105 plus languages spoken today may disappear by end of this century. When a language becomes extinct, communities lose their cultural identity, practices tied to a language and intellectual wealth. The rapid loss of languages motivates this study. We first introduce collective intelligence, endangered languages, and language revitali...

T he Endangered Species Act of 1973 addresses the market failure associated with the unpriced social benefits of such species. Robert Barnwell Roosevelt might have been envisioning such an act in his 1865 book Superior Fishing, where he wrote: ‘‘By these means can the seductive little beauties, whether of the feathered, furred, or scaly tribe . . . be preserved through endless time in undiminis...

Large-scale rodent control can help to manage endangered species that are vulnerable to invasive rodent consumption. A 26 ha rodent snap-trap grid was installed in montane forest on Oahu Island, Hawaii, in order to protect endangered snails and plants. To assess the effectiveness of this trapping operation in reducing fruit consumption and seed predation of the endangered Hawaiian lobeliad, Cya...

Habitat destruction and overhunting are two major drivers of mammal population declines and extinctions in tropical forests. The construction of roads can be a catalyst for these two threats. In Southeast Asia, the impacts of roads on mammals have not been well-documented at a regional scale. Before evidence-based conservation strategies can be developed to minimize the threat of roads to endan...

In order to contribute to conservation of the endangered Kiso horse, we clarified their genetic information using 31 microsatellite DNAs, and genotyped 125 horses, 83% of the existing breed. First, we clarified the current status of the horses. The horses were confirmed to have experienced rapid loss of population causing a bottleneck, and their effective population size was much smaller than t...

The rate at which endangered languages can be documented has been highly constrained by human factors. Although digital recording of natural speech in endangered languages may proceed at a fairly robust pace, transcription of this material is not only time consuming but severely limited by the lack of native-speaker personnel proficient in the orthography of their mother tongue. Our NSF-funded ...

Cooperative Extension is an ideal facilitator for volatile wildlife issues such as endangered species management on private lands. Often, lack of trust in government agencies or fear of Endangered Species Act regulations hinders conservation efforts on these private lands. Extension personnel have close ties to local affected communities and thus can be instrumental in educating landowners rega...
