‘Putting the right species back in the right place’: expressed in the words of Bruce Pavlik, the Head of Restoration Ecology at the Millennium Seed Bank at Kew Gardens in a fundraising clip for the Breathing Planet Campaign, the work of biodiversity repositories seems straightforward. A simple matter of renewing the colonial and capitalistic capture of nature by exhausting its diversity in collecting, and then of reinserting species, suspended in the form of genetic information, into the neat spaces their disappearance or almost-dispappearance has left in their original ecosystems, the redemptive value of biodiversity repositories seems unquestionable. ‘There is no technological reason why any species should go extinct’, the clip goes on.The cryopreservation of genetic material in seed banks and ‘frozen zoos’ is often and justifiably understood as genetic-fetishistic suspension, several times removed from animal lives in actual habitats; I propose however to read them as world-making devices in their own right too, more entangled and entangling than they might present themselves to be. Collecting and saving are two mandates that have effects both on the species whose genetic information is banked and on the natures that are made possible or impossible through the projects delineated by biodiversity repositories; but they have also been implicated in a third such mandate, the assisted adaptation of species to anthropogenic climate change (be it the plan for ‘chaperoned assisted relocation’ proposed by the Missouri Botanical Garden or the ‘cultivation of marginally hardy taxa’ proposed at the Arnold Arboretum). How are biodiversity repositories an active intervention into the shaping of natures both inside and outside, and what are the consequences of what happens within the apparatus of these repositories for wider understandings of landscapes and species under threat? How linked is the suspension of metabolic processes and evolutionary potential and the understanding of Earth as manageable, perhaps even terraformable? What do they contribute to conservation biology’s biopolitical and cultural shaping of individuals, species, ecosystems suspended and remade through the different uses for which biodiversity repositories can be put to work?

Conservation seed banks are essential for ex-situ conservation of genetic biodiversity. These institutions are especially relevant for threatened species and play a vital role in their conservation by preserving genetic material. However, samples deposited in the seed banks must germinate when necessary to use them (i.e., recovery plans, etc.). This study uses four accessions of the endemic endangered species from Gran Canaria Island (Canary Islands), Isoplexis isabelliana (Webb & Berthel.) Masf. (Scrophulariaceae). Germination tests were carried out to measure seed viability through time and the possible impact of seed storage on their viability. These accessions have been kept in the seed bank for four months to thirty years under different storage conditions. Germination results differed for seeds after 45 days of exposition using 16 hours light and 8 hours darkness at 17 °C. Accessions kept in the seed bank, independently of storage, showed a high germination percentage (89%). Whereas the accessions with rough storage conditions showed a 0% germination rate. The results highlighted the good state of conservation of the material deposited in the Seed Bank of the Botanical Garden "Viera y Clavijo" and the reliability of the temperature and humidity conditions in which the seeds of I. isabelliana have been stored. We consider these results as momentous since several natural populations of I. isabelliana has been affected by the last forest fire on the island.

Abstract This work refers to the native species of genus Astragalus L. (A. dasyanthus, A. ponticus), Adonis L. (A. vernalis, A. wolgensis) and Digitalis L. (D. lanata, D. grandiflora). The plants are cultivated in the Botanical Garden of Moldova in the field collection of the medicinal and aromatic plants. Investigation includes propagation aspects, research into cultivation techniques and conservation measures. The biological particularities and the phenologic rhythm are also registered. The obtained data shows the ecological flexibility of species and the possibility of preserving them in culture.
