The proposed research aims to define mechanisms of survival and speciation that underpin the capacity of a novel group of Antarctic microorganisms to evolve dominance in their very cold (-20 degrees Celsius) and very salty environment. Most (~85 per cent) of the Earth's biosphere is cold (<5 degrees Celsius), and yet contains a rich diversity of microorganisms of which we know little. The uniqueness and sensitivity of Antarctica particularly demands that we rapidly improve our understanding of its biology. The discoveries made could provide fundamental insight about speciation - processes controlling which life forms that colonise the planet.

这项拟议的研究旨在确定生存和物种形成的机制，这些机制支持一组新的南极微生物在非常寒冷（-20摄氏度）和非常咸的环境中进化优势的能力。地球生物圈的大部分（约85%）是寒冷的（<5摄氏度），但含有丰富多样的微生物，我们对此知之甚少。南极洲的独特性和敏感性特别要求我们迅速提高对其生物学的认识。这些发现可以提供有关物种形成的基本见解-控制哪些生命形式殖民地球的过程。
