Cryopreservation of amphibian genomes: targeting the Holy Grail, cryopreservation of maternal haploid and embryonic diploid genomes
Integrating biobanking could produce significant cost benefits and minimise inbreeding for Australian amphibian captive breeding programs
Captive breeding is an important tool for amphibian conservation despite high economic costs and deleterious genetic effects of sustained captivity and unavoidably small colony sizes. Integration of biobanking and assisted reproductive technologies (ARTs) could provide solutions to these challenges, but is rarely used due to lack of recognition of the potential benefits and clear policy direction. Here we present compelling genetic and economic arguments to integrate biobanking and ARTs into captive breeding programs using modelled captive populations of two Australian threatened frogs, namely the orange-bellied frog Geocrinia vitellina and the white bellied frog Geocrinia alba. Back-crossing with frozen founder spermatozoa using ARTs every generation minimises rates of inbreeding and provides considerable reductions in colony size and program costs compared with conventional captive management. Biobanking could allow captive institutions to meet or exceed longstanding genetic retention targets (90% of source population heterozygosity over 100 years). We provide a broad policy direction that could make biobanking technology a practical reality across Australiaâs ex situ management of amphibians in current and future holdings. Incorporating biobanking technology widely across this network could deliver outcomes by maintaining high levels of source population genetic diversity and freeing economic resources to develop ex situ programs for a greater number of threatened amphibian species

Envisioning the future with âcompassionate conservationâ:An ominous projection for native wildlife and biodiversity
The âCompassionate Conservationâ movement is gaining momentum through its promotion of âethicalâ conservation practices based on self-proclaimed principles of âfirst-do-no-harmâ and âindividuals matterâ. We argue that the tenets of âCompassionate Conservationâ are ideological - that is, they are not scientifically proven to improve conservation outcomes, yet are critical of the current methods that do. In this paper we envision a future with âCompassionate Conservationâ and predict how this might affect global biodiversity conservation. Taken literally, âCompassionate Conservationâ will deny current conservation practices such as captive breeding, introduced species control, biocontrol, conservation fencing, translocation, contraception, disease control and genetic introgression. Five mainstream conservation practices are used to illustrate the far-reaching and dire consequences for global biodiversity if governed by âCompassionate Conservationâ. We acknowledge the important role of animal welfare science in conservation practices but argue that âCompassionate Conservationâ aligns more closely with animal liberation principles protecting individuals over populations. Ultimately we fear that a world of âCompassionate Conservationâ could stymie the global conservation efforts required to meet international biodiversity targets derived from evidenced based practice, such as the Aichi targets developed by the Convention on Biological Diversity and adopted by the International Union for the Conservation of Nature and the United Nations.Fil: Callen, Alex.
