Abstract A new synergistic approach of classical conservation strategies combined with advanced assisted reproduction technologies (aART) allows for protection and rescue endangered keystone species at the brink extinction, which can help to safeguard complex ecosystems. Reproduction biology management in mammal is not only challenging regards their diverging sizes, anatomy, often unknown physiology; it also requires customized training or chemical restraint protocols safe handling. Besides these general challenges, there are several techniques (ART) specifically tailored critically mammals. The current portfolio ART mammalian taxa ranging from sexual cycle characterization manipulation, semen collection cryopreservation, artificial insemination, biobanking living cells, oocyte collection, vitro fertilization (IVF), embryo production, transfer as well stem cell‐derived gametogenesis generating gametes culture. article covers (aART), success ethical implications.

Abstract An endangered black-footed ferret female that died in 1988 with no living descendants the current population was successfully cloned from cryopreserved cells using cross-species somatic cell nuclear transfer, producing three healthy kits. Incorporating progeny these clones would provide an 8th founder to breeding program and increase genetic variation species’ limited gene-pool. This marks first time a native U.S. species has been cloned.
