The U.S. Endangered Species Act (ESA) requires listing of a species as threatened or endangered not only when it is at risk of worldwide extinction, but also when it is at risk in any “significant portion of its range” (SPOIR) (16 U.S.C. Section 1532(6)). Many species have been listed as endangered under the ESA in part because they were threatened in a SPOIR (e.g., FWS 1990, 1995, 2000). On 16...

EXECUTIVE SUMMARY The Endangered Species Act of 1973 (ESA) employs a two-category system: listing species either as endangered (in danger of extinction throughout all or a significant portion of its range) or threatened (likely to become endangered in the foreseeable future). Absence of Congressional guidance on how to interpret the terms used in the statutory definitions of these categories ha...

Conservation research is essential to help inform the science-based management of environments that support threatened and endangered wildlife; however, research effort is not necessarily uniform across countries globally. Here, we assessed how the research importance of conservation is distributed globally across different countries and what drives this variation. Specifically, we compared the...

One in five of the world's plant species is threatened with extinction according to the 2010 first global analysis of extinction risk. Tilman et al. predicted a massive ecological change to terrestrial plants within the next 50-100 y, accompanied by an increase in the number of global plant species facing extinction [Tilman D, et al. (2001) Proc Natl Acad Sci USA 98(10):5433-5440]. Most of the ...

Despite the volume of the academic conservation biology literature, there is little evidence as to what effect this work is having on endangered species recovery efforts. Using data collected from a national review of 136 endangered and threatened species recovery plans, we evaluated whether recovery plans were changing in response to publication trends in four areas of the academic conservatio...

Compared with the numerous studies on Chiroptera in other countries only little information has been published on Nepalese bats. Status of bats in Nepal has not been identified and even not given more interest by the government body which is devoted to wildlife managements itself. In Nepal, out of 51 species recorded by CAMP in 2002, 2 are critically endangered, 1 endangered and 5 are vulnerabl...

Threatened species programs need a social license to justify public funding. A contingent valuation survey of a broadly representative sample of the Australian public found that almost two thirds (63%) supported funding of threatened bird conservation. These included 45% of a sample of 645 respondents willing to pay into a fund for threatened bird conservation, 3% who already supported bird con...

Pesce, G. L.: The Zinzulusa cave: an endangered biodiversity »hot spot« of South Italy. Nat. Croat., Vol. 10, No. 3., 207–212, 2001, Zagreb. The historical, geological, faunistic and ecological characteristics of the Zinzulusa cave (Castro Marina, South Italy), one of the most remarkable anchialine aquifers of Italy, are presented in this paper. The results of recent explorations and discoverie...

In the recent era, due to tremendous advancement in industrialization, pollution and other anthropogenic activities have created a serious scenario for biota survival. It has been reported that present biota is entering a "sixth" mass extinction, because of chronic exposure to anthropogenic activities. Various ex situ and in situ measures have been adopted for conservation of threatened and end...
