Wiley Research News The Galapagos Islands have an iconic status in the history of evolutionary study, now new research shows that the islands’ own geological past may have influenced the evolution of the chain’s native species. Writing in the Journal of Biogeography, Jason Ali and Jonathan Aitchison explore how fluctuating sea level changes over thousands of years impacted the island chain’s ecology. They estimate that when the sea retreated, most recently 20,000 years ago,...

Model of island ecology sheds new light on the origins of island species Animal and bird species found only on a single island should still be common within that island. This is the finding of a new model developed by researchers from the University of Leeds and Imperial College London. The model could apply both to actual islands and isolated areas of habitat on the mainland that are home to unique species, such as the table top mountains of South America. The natural history of islands is...

According to evolutionary theory, natural selection favours traits that enhance dispersal of populations to new habitats. The empirical evidence supporting this theory, however, is relatively scarce. A study carried out by researchers from the Faculty of Biological and Environmental Sciences of the University of Helsinki, along with their Swedish colleagues, reports rapid evolution of traits facilitating dispersal in an outer archipelago. The results was published today in the Proceedings of...
