AbstractThe Anthropocene is marked by profound changes in biodiversity and the ecosystems in which species live. A primary signature of this change is the often rapid change in species composition through time (i.e., species turnover) rather than changes in the numbers of species per se.

1 INTRODUCTION Contemporary climate change has triggered the largest redistribution of life on Earth in the last tens of thousands of years (Chen et al., 2011; Lenoir et al., 2020; Parmesan, 2006). Yet, attributing the variation observed among species range shifts to specific mechanisms governing these range shift processes remains unresolved.

Combining species range-shift estimates with population trends for 146 marine species reveals that population abundances tend to decline as the velocity with which the species’ range is shifting poleward increases. The findings suggest widespread transient population dynamics rather than a simple dichotomy between climate-change ‘winners’ and ‘losers’.
