While Arctic tundra greening and browning have received increasing attention over the past decade, one comparatively understudied area is the role of sea ice dynamics and decline as drivers of terrestrial vegetation change and the ecological consequences. A new study, published in the Proceedings of the National Academy of Sciences of the United States of America, reveals two important insights that will have important implications for tundra productivity and vegetation-climate feedback.

Evolution of multiple species from a single colonizer is something that has happened repeatedly on oceanic islands. Such radiations, can lead to tens or even hundreds of distinct species, often occupying a range of very different habitats with the expectation that these 'evolutionary winners' will be species so well-tuned to their island environments that they should also be locally successful and abundant. In a new study in Journal of Biogeography, an international team including Prof Rob Whittaker, has shown that it may not be so simple.
