Knowledge about the consequences of Arctic warming for marine biogeography remains limited. Mytilus mussels play a key ecological role in the littoral zone, and they are expected to be sensitive to climate change. Here we used a space-for-time approach as a first attempt to infer the coupling between climate warming and population structure and abundance of intertidal mussels along a latitudinal climate gradient in west Greenland. We analysed trends in air temperatures, collected seasonal temperature data from intertidal microhabitats, and quantified abundance, growth and age structure at 73 sites in 5 fjords. We also compared tolerance to sub-zero temperatures between seasons and latitudes. Since 1958, atmospheric temperatures have increased signifi- cantly in all fjords. Consequently, the number of days with temperatures below the lower lethal temperature, LT50 (−13°C), has decreased by up to 57%, suggesting that constraint by low tempera- ture is weakening. Abundance declined >95% with increasing latitude from an average of 23.67 to 0.71 ind. 0.0625 m−2 in mid-intertidal habitats. However, no latitudinal differences in growth, aver- age size (6.3−9 cm), age (1.5−2.5 yr) and mortality (55.9−62.5 yr−1) were found.
