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% of Earth’s terrestrial environments and, through COP 28, to mitigate the effects of the climate catastrophe on the biosphere. We focused this review on three core themes: the need and potential of reproduction biotechnologies, biobanks, and conservation breeding programs (RBCs) to satisfy sustainability goals; the technical state and current application of RBCs; and how to achieve the future potentials of RBCs in a rapidly evolving environmental and cultural landscape. RBCs include the hormonal stimulation of reproduction, the collection and storage of sperm and oocytes, and artificial fertilisation. Emerging technologies promise the perpetuation of species solely from biobanked biomaterials stored for perpetuity. Despite significant global declines and extinctions of amphibians, and predictions of a disastrous future for most biodiversity, practical support for amphibian RBCs remains limited mainly to a few limited projects in wealthy Western countries. We discuss the potential of amphibian RBCs to perpetuate amphibian diversity and prevent extinctions within multipolar geopolitical, cultural, and economic frameworks. We argue that a democratic, globally inclusive organisation is needed to focus RBCs on regions with the highest amphibian diversity. Prioritisation should include regional and international collaborations, community engagement, and support for RBC facilities ranging from zoos and other institutions to those of private carers. We tabulate a standard terminology for field programs associated with RBCs for publication and media consistency.

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

Geothermal springs are scattered worldwide and harbor thermophilic cyanobacteria, whose species distribution depends on extreme environmental conditions. The optical growth of cyanobacteria in hot springs and their metabolic diversity represent a source for possible biotechnological tools. In the current study, we isolated and characterized the cyanobacterial community of water samples from El Salado and Papallacta geothermal springs in Ecuador. We employed a culture-dependent as well as a polyphasic approach, which includes morphological examination by light microscopy, molecular analysis of 16S and 23S rRNA genes, and phylogenetic position using the maximum likelihood method. Notably, the morphological and molecular analyses complemented each other. Furthermore, we isolated eleven strains that belong to the taxa Tenebriella amphibia, Calothrix, Planktothricoides raciborskii, Nostoc, Fischerella muscicola, Leptolyngbya, Synechococcus, Komvophoron jovis, Chroococcales and Nostocacea. Both hot springs, whose temperature ranged between 45 and 54 °C, could harbor cosmopolitan and endemic cyanobacteria. Our study establishes a baseline for future efforts to exploit potential biotechnological tools bioprospected from these isolated microorganisms.
