Abstract Two endangered Przewalski’s horse stallions were cloned from fibroblast cells cultured and cryopreserved in 1980. These are clones of a male that lived 1975-1998 pedigree analyses identified as genetically valuable for present-day conservation breeding. This is the first time multiple healthy have been produced an species.

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.

Intergenerational justice entitles the maximum retention of Earth’s biodiversity. The 2022 United Nations COP 15, “Ecological Civilisation: Building a Shared Future for All Life on Earth”, is committed to protecting 30% terrestrial environments and, through 28, mitigate effects climate catastrophe biosphere. We focused this review three core themes: need and potential reproduction biotechnologies, biobanks, conservation breeding programs (RBCs) satisfy sustainability goals; technical state current application RBCs; how achieve future potentials RBCs in rapidly evolving environmental cultural landscape. include hormonal stimulation reproduction, collection storage sperm oocytes, artificial fertilisation. Emerging technologies promise perpetuation species solely from biobanked biomaterials stored perpetuity.

The documentation, preservation and rescue of biological diversity increasingly uses living samples. Persistent associations between species, biosamples, such as tissues cell lines, the accompanying data are indispensable for using, exchanging benefiting from these valuable materials. Explicit authentication biosamples by assigning unique robust identifiers is therefore required to allow unambiguous referencing, avoid identification conflicts maintain reproducibility in research. A predefined nomenclature based on uniform rules would facilitate this process. However, a currently lacking animal material. We here present first, standardized, human-readable design, which sufficient generate stable identifying names cellular material with focus wildlife species. species-specific human- machine-readable syntax included proposed standard naming scheme, allowing traceability donated cultured cells, well FAIRification. Only when it consistently applied public domain, publications inter-institutional samples exchanged, distributed stored centrally, can risks misidentification loss be mitigated. This innovative globally applicable system provides sustainable structure long-term storage bio-samples cryobanks hence facilitates current future species conservation biomedical

Conservation and animal wellbeing are two key goals of the modern zoo aquarium. In case ex situ conservation breeding programs, there is a unique paradox between these concepts; on some occasions, facilities must balance mitigate arising conflicts animals with project. Exerting control over reproductive lives animals—choosing when where they breed, whom breed with, whether prohibited altogether, so on—results in an inherent reduction animal’s agency. Considering growing recognition that providing choice to enhances wellbeing, it essential examine how populations their managed. The present review presents challenges supporting agency for bred by thoroughly exploring practical realities working animals. Various areas consideration, including current research directions, suggestions future practices, opportunities moving forward, highlighted. importance careful population management maximising dichotomy necessity limit autonomy preserve while meeting needs programs.

Primary themes in intergenerational justice are a healthy environment, the perpetuation of Earth's biodiversity, and sustainable management biosphere. However, current rate species declines globally, ecosystem collapses driven by accelerating catastrophic global heating, plethora other threats preclude ability habitat protection alone to prevent cascade amphibian mass extinctions. Reproduction advanced biotechnologies, biobanking germplasm somatic cells, conservation breeding programs (RBCs) offer transformative change biodiversity management. This can economically reliably perpetuate irrespective environmental targets extend satisfy humanity's future needs as biosphere expands into space. Currently applied RBCs include hormonal stimulation reproduction, collection refrigerated storage sperm oocytes, cryopreservation, vitro fertilization, cells. The benefits biotechnologies development, such assisted evolution cloning for adaptation or restoration, have yet be fully realized. We broaden our discussion genetic management, political cultural engagement, applications, including extension through interplanetary interstellar colonization. development application raise intriguing ethical, theological, philosophical issues. address these with models introduce Multidisciplinary Digital Publishing Institute Special Issue, Sixth Mass Extinction Species Sustainability Biotechnologies, Biobanking, Conservation Breeding Programs.

Intergenerational Justice entitles the maximum retention of Earth’s Biodiversity. The United Nations COP 15 committed to protection 30% terrestrial environments provide Biospheric Sustainability. However, proactive amphibian sustainability needs support from Reproduction Technologies, Biobanking, and Conservation Breeding Programs [RBCs]. These technologies include reliable practice stimulation reproduction collection sperm oocytes, refrigerated cryopreserved storage, in vitro fertilization. Emerging promise perpetuation species solely biobanked biomaterials. although exemplary national programs for RBCs are now established USA Australia, these potentials not fully realised resulting unacceptable biodiversity loss. To realise an independent democratic global organisation is proposed to, 1) focus on bioregions with highest biodiversity, 2) maximise regional inclusion international initiatives, 3) community engagement financial resources. We present first overall multidisciplinary review RBCs, including their geopolitical, cultural, scientific background, along development application economically, efficiently, reliably, perpetuate biodiversity. genetic models, potential diploid cell cryopreservation species, significant new information methodologies techniques, standardise nomenclature specificity publications media consistency.
