Genotyping of endangered species is helpful for establishing and evaluating conservation strategies. Mitochondrial sequence data was analyzed from 541 individuals of a critically endangered fish, Acheilognathus typus from present-day range-wide localities to re-evaluate an in-progress restoration program around Lake Izunuma-Uchinuma, Miyagi, Japan. Acheilognathus typus showed low sequence diver...

Examining the scientific process in relation to endangered data, data reuse, and sharing is crucial in facilitating scientific workflow. Deterioration, format obsolescence, and insufficient metadata for discovery are significant problems leading to loss of scientific data. The research presented in this paper considers these potentially lost data. Four one-hour focus groups and a demographic su...

Loach minnow (Rhinichthys cobitis) and spikedace (Meda fulgida) are legally protected with the status of Endangered under the U.S. Endangered Species Act and are endemic to the Gila River basin of Arizona and New Mexico. Efficient and sensitive methods for monitoring these species' distributions are critical for prioritizing conservation efforts. We developed quantitative PCR assays for detecti...

During the twentieth and twenty-first centuries, Robert Paul Lanza studied embryonic stem cells [5], tissues, and endangered species as chief scientific officer of Advanced Cell Technology, Incorporated in Worcester, Massachusetts. Lanza's team cloned the endangered species of gaur Bos gaurus [6]. Although the gaur did not survive long, Lanza successfully cloned another cow [7]-like creature, c...

Digital archiving is important work for an endangered language, because if an endangered language disappears, associated cultural assets will disappear altogether. Several digital archiving projects are being conducted in Taiwan. Many tribal teachers are now involved in these projects. Based on the needs of these tribal teachers, this paper presents an easyto-use system for digitally archiving ...

Chicken primordial germ cells (PGCs) are used to restore and conserve genetic resources of some endangered birds or flocks of domestic chickens. When PGCs are transferred from a donor to a recipient, they can survive and gain sexual maturity in the recipient chicken. This indicates that PGCs retaining exogenous genes can proliferate and develop in recipient gonads, and proves that transferred P...

During fieldwork in Fiji, four new species of Cyrtandra (Gesneriaceae) were discovered and are described herein: C. gregoryi M.A.Johnson, sp. nov., C. hispida M.A.Johnson, sp. nov., C. longifructosa M.A.Johnson, sp. nov., and C. waisaliensis M.A.Johnson, sp. nov. The addition of four new species brings the current number of Fijian Cyrtandra to 41 endemic species. Two of the four species are kno...

By identifying the traits that characterize species likely to become endangered or fade to extinction, it is possible to afford them and their habitats extra protection and carefully monitor their status. The tragic losses of so many of these "red flag" species should be avoided in the future, and can be, with remedial action. Ideally, species should be conserved when their populations are stil...

Reintroductions of endangered species are controversial because of high costs and frequent failures. However, the population of black-footed ferrets descended from animals released in Shirley Basin, Wyoming, from 1991 to 1994 has grown rapidly after a decline to a low of five animals in 1997. Beginning around 2000, the population grew rapidly to an estimated 223 (95% confidence interval is 192 ...

Efforts to clone some rare, endangered and even extinct species have created controversy amongst conservation bodies who think resources could be much better directed. Kenneth Lee reports.
