Analysis of thousands of species finds some invertebrates and plants also getting smaller, while others are increasing in body size

Species such as the thorny skate, a north Atlantic fish that can grow up to a metre in length, have become smaller, while smaller-bodied species such as mackerel are growing in abundance, according to the researchers, changing the composition and functioning of ecosystems.
