Beskrivning av projektet
Our planet has experienced periods of global warming and cooling. Periods of climate change often force species to change their distributions; this is particularly likely for Antarctic marine species as the global temperature determines the amount of ice that covers the sea floor. One outcome of a change in distribution is that populations can become genetically different, and this process can generate new species (biodiversity). In this project, we sequence the genomes of many Antarctic octopus species to determine whether they are similarly adapted to the depth at which they live, as changes in the depth of habitat likely occurred with historic shifts in ice cover. Also, we examine the controversial idea that species moved to quite different parts of the Southern Ocean during a period of climate change when it has been hypothesised that the Western Antarctic Ice Sheet collapsed to open up a passage between the Ross and Weddell Seas.
