Present‐day sympatry belies the evolutionary origin of a high‐order polyploid

open access: yesNew Phytologist, Volume 216, Issue 1, Page 279-290, October 2017., 2017
Summary Disentangling the evolutionary histories of polyploids, especially those with high ploidies, can reveal fundamental processes in speciation. Despite occurring frequently during evolution, the origins of many extant polyploid plant species remain largely unknown. By integrating linkage mapping, polyploid phylogeny and sex‐determining region (SDR)

Beyond the nation and into the state: identity, belonging, and the ‘hyper‐border’

open access: yesTransactions of the Institute of British Geographers, Volume 41, Issue 2, Page 201-215, April 2016., 2016
The case of the disputed Southern Kuril Islands/Northern Territories is used to introduce the term ‘hyper‐border’ in order to examine the instrumental and pragmatic nature of identity. It seeks to capture how, on one of Russia's most isolated borders, the quotidian realities and challenges of life ‘beyond’ the state had profound implications for how ...
