A new study, published in Science, which focuses on mapping biodiversity change in marine and land ecosystems shows that loss of biodiversity is most prevalent in the tropic, with changes in marine ecosystems outpacing those on land. The research, led by scientists from the University of St Andrews, in collaboration with leading universities across Europe, the USA and Canada, including McGill, aimed at reaching a consensus about variation in biodiversity change. It found that there were both negative and positive changes in ecosystems across the world and that although on average the numbers of species that live in each place are not changing, many regions were either gaining or losing species.
