Project Summary of the Season 2016/17
As part of this project we have also shown that, more generally, while genetic connectivity among sub-Antarctic islands is clearly pronounced in some marine species, in both terrestrial and other marine organisms the connectivity is less pronounced both within and among islands, resulting in significant genetic structuring. In consequence, much reason exists to ensure that biosecurity protocols emphasize both introductions from outside the region, and intra-regional transfers. Most genetic work has, to date, used standard markers. Next Generation Sequencing approaches are suggesting even greater structure, indicating that additional work using these methods could benefit biosecurity approaches for the region, and in particular as a means to distinguish climate change-associated colonization events from anthropogenic ones.
