Can cloning save endangered species?

Biology, Policy and Law in Endangered Species Conservation: I. The Case History of the Island Fox on the Northern Channel Islands

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...

Cloning of an endangered species (Bos gaurus) using interspecies nuclear transfer.

Approximately 100 species become extinct a day. Despite increasing interest in using cloning to rescue endangered species, successful interspecies nuclear transfer has not been previously described, and only a few reports of in vitro embryo formation exist. Here we show that interspecies nuclear transfer can be used to clone an endangered species with normal karyotypic and phenotypic developmen...

Cloning advances and challenges for conservation.

Although controversy surrounds cloning efforts, the cloning of animals to assist efforts to preserve genetic variation in support of endangered species conservation efforts has attracted serious interest. A recent report by Loi et al. describing the cloning of a mouflon (a species of wild sheep) in a domestic sheep surrogate points to potential conservation opportunities and additional challeng...

Embryonic development and growth performances of an endangered fish species Nandus nandus: effects of dietary polyunsaturated fatty acids supplementation

The present study explored the embryonic and larval development of an endangered fish species Nandus nandus and resolved larval growth performances with the dietary supplementation of different types of lipids. Fertilized eggs were collected from fiber glass tanks immediately after spontaneous spawning of N. nandus, which were fed with a 1% phospholipid (squid meal) supplemented diet for 3 mont...
