A genome-wide investigation of the effect of farming and human-mediated introduction on the ubiquitous seaweed *Undaria pinnatifida*

L. Graf, Y. Shin, et al.

Explore how human activities shape ecological and evolutionary changes in the Pacific kelp *Undaria pinnatifida*. This groundbreaking study reveals genetic distinctions in natural, cultivated, and introduced populations, shedding light on the influences of both selection and migration. Research conducted by Louis Graf, Younhee Shin, Ji Hyun Yang, Ji Won Choi, II Ki Hwang, Wendy Nelson, Debashish Bhattacharya, Frédérique Viard, and Hwan Su Yoon.

Abstract
Human activity significantly impacts ecological and evolutionary change. This study uses the Pacific kelp *Undaria pinnatifida*, cultivated in Northeast Asia and introduced to other continents, for a genome-wide analysis of natural, cultivated, and introduced populations. The results show that these categories are distinguishable at the genome level due to both neutral (demography and migration) and non-neutral (selection) processes.
