A role for molecular genetic approaches in conservation of endangered taxa is now commonly recognized. Because conservation genetic analyses provide essential insights on taxonomic status, recent evolutionary history and current health of endangered taxa, they are considered in nearly all conservation programs. Genetic analyses of the critically endangered Far Eastern, or Amur leopard, Panthera...
The U.S. federal government allocates resources for the protection of endangered species. Using an ordinary least squares regression, the study analyzes what variables affect the amount of funds an endangered vertebrate receives from the federal government. The results suggest that animal size affects spending decisions. Specifically, larger animals receive more money. Animals designated as hig...
In this paper, we describe how field linguists can use the WordsEye Linguistics Tool (WELT) to study endangered languages. WELT is a tool under development for eliciting endangered language data and formally documenting a language, based on WordsEye (Coyne and Sproat, 2001), a text-to-scene generation tool that produces 3D scenes from text input. First, a linguist uses WELT to create elicitatio...

This paper describes on-going work in dictionary digitization, and in particular the processing of OCRed text into a structured lexicon. The description is at a conceptual level, without implementation details. In decades of work on endangered languages, hundreds (or more) languages have been documented with print dictionaries. Into the 1980s, most such dictionaries were edited on paper media (...
Global biodiversity is strongly influenced by the decrease in endangered biological species. Predicting the distribution of endangered medicinal plants is necessary for resource conservation. A spatial distribution model-geographic information system for global medicinal plants (GMPGIS)-is used to predict the global potential suitable distribution of four endangered Panax species, including Pan...
Oceanic island ecosystems are vulnerable to the introduction of alien species, and they provide a habitat for many endangered species. Knowing the diet of an endangered animal is important for appropriate nature restoration efforts on oceanic islands because introduced species may be a major component of the diets of some endangered species. DNA barcoding techniques together with next-generatio...
The management of endangered species under climate change is a challenging and often controversial task that incorporates input from a variety of different environmental, economic, social, and political interests. Yet many listing and recovery decisions for endangered species unfold on an ad hoc basis without reference to decision-aiding approaches that can improve the quality of management cho...
This paper, an annotated list of Ohio's rare and endangered vertebrate species, was compiled to supplement a similar national list and includes 10 mammals, 62 birds, 10 reptiles, 4 amphibians, and 33 fishes. Where possible, suggestions are made both as to causes of the rare or endangered status of these species and as to means of halting the trend. Ratings of "endangered," "rare," "peripheral,"...
C. Josh Donlan Department of Ecology and Evolutionary Biology, Cornell University Ithaca, New York 14853-2701 and Island Conservation University of California Long Marine Laboratories Santa Cruz, California 95060 Abstract Endangered species recovery often requires strategies that are risky, contentious, and difficult to implement. These qualities can lead to recovery actions that result from hu...
