Abstract:
... Wildlife extinctions are thought to be occurring more rapidly than at any time in the history of the earth, mainly because of human activities. These include agriculture, urbanization, deforestation and a myriad other processes. While it is impractical to think that reproductive technologies could be used on a grand scale to help save large numbers of species from extinction, the judiciously targe ...

Abstract:
... The dredge oyster, Ostrea chilensis, is native to New Zealand and Chile. Although this species has been commercially fished for decades, it is only recently that farming trials have been initiated. The “wild” commercial fishery was decimated in the 1980s by the parasite, Bonamia and so breeding for disease resistance is imperative for the progress of the aquaculture industry. Cryopreservation can ...

Abstract:
... Cryopreservation can be a powerful tool in shellfish aquaculture for selective breeding programmes and hatchery production. Most species that are commercially farmed are broadcast spawners, releasing sperm and eggs into the environment where they fertilize and develop. However, some species are brooders (e.g. flat oysters (Ostrea chilensis)), which retain and rear embryos until they reach later de ...

Abstract:
... Onion thrips (Thrips tabaci Lindeman) has become a significant pest of cabbage (Brasssica oleracea L.) in regions with a dry continental climate. Thrips-resistant cabbage varieties have been developed in breeding programs, but the mechanisms of resistance remain largely unknown. Antixenosis, one of the three resistance mechanisms, may play a role but no plant trait has been identified as a source ...
