Community composition (relative abundance) separated by native and cryptogenic, and introduced species of each community from coastal sites across a geographic gradient spanning the sub-arctic to the tropics from 2015-2017

Community composition of sessile marine invertebrates from coastal sites across a geographic gradient spanning the sub-arctic to the tropics. Community composition is divided into two data sets. One corresponds to the community composition of the introduced species found in each community, and the other data set corresponds to the community composition of native and cryptogenic species found in each community.
