Keystone predators govern the pathway and pace of climate impacts in a subarctic marine ecosystem.
Douglas B. Rasher,Robert S. Steneck,Jochen Halfar,Kristy J. Kroeker,Justin B. Ries,M. Tim Tinker,M. Tim Tinker,P. Chan,P. Chan,Jan Fietzke,Nicholas A. Kamenos,Brenda Konar,Jonathan S. Lefcheck,Chris J. D. Norley,Benjamin P. Weitzman,Benjamin P. Weitzman,Isaac T. Westfield,James A. Estes +17 more
TL;DR: It is shown that massive calcareous reefs, built slowly by the alga Clathromorphum nereostratum over centuries to millennia, are now declining because of the emerging interplay between these two processes, and the effects caused by the absence of this predator can be further exacerbated by climate warming.
225 years of Bering Sea climate and ecosystem dynamics revealed by coralline algal growth-increment widths
Jochen Halfar,Branwen Williams,Steffen Hetzinger,Robert S. Steneck,P. A. Lebednik,C. Winsborough,A. Omar,P. Chan,Alan D. Wanamaker +8 more
TL;DR: In this article, the authors present the first record compiled from annual growth-increment widths of long-lived coralline algae collected in shallow-water habitats spanning the entire Aleutian Islands.

Multicentennial record of Labrador Sea primary productivity and sea-ice variability archived in coralline algal barium.
P. Chan,Jochen Halfar,Walter H. Adey,Steffen Hetzinger,Thomas Zack,G. W. K. Moore,Ulrich G. Wortmann,Branwen Williams,A. Hou +8 more
TL;DR: In this article, the authors reconstruct an annually resolved record of Labrador Sea productivity related to sea-ice variability in Labrador, Canada that extends well into the Little Ice Age (LIA; 1646 AD).
Recent density decline in wild-collected subarctic crustose coralline algae reveals climate change signature
P. Chan,Jochen Halfar,Walter H. Adey,P. A. Lebednik,Robert S. Steneck,Chris J. D. Norley,David W. Holdsworth +6 more
TL;DR: A century-long annually resolved growth, density, and calcification rate record from the crustose coralline alga Clathromorphum nereostratum, a dominant calcifier in Pacific Arctic and subarctic benthic communities, was presented in this article.

Long-lived coralline alga records multidecadal variability in Labrador Sea carbon isotopes
A. Hou,Jochen Halfar,Walter H. Adey,Ulrich G. Wortmann,Zoltán Zajacz,Alexandra Tsay,Branwen Williams,P. Chan +7 more
TL;DR: In this paper, the authors used an annually-banded coralline alga live-collected from the Labrador shelf to generate a 266-year time series of oceanic dissolved inorganic carbon (DIC) changes in the Labrador Sea.
