Ecological Consequences of Sea-Ice Decline
@article{Post2013EcologicalCO, title={Ecological Consequences of Sea-Ice Decline}, author={Eric Post and Uma S. Bhatt and Cecilia M. Bitz and Jedediah F.

After a decade with nine of the lowest arctic sea-ice minima on record, including the historically low minimum in 2012, we synthesize recent developments in the study of ecological responses to sea-ice decline. Sea-ice loss emerges as an important driver of marine and terrestrial ecological dynamics, influencing productivity, species interactions, population mixing, gene flow, and pathogen and disease transmission. Major challenges in the near future include assigning clearer attribution to sea…

Advancing plant phenology and reduced herbivore production in a terrestrial system associated with sea ice decline
- Environmental ScienceNature Communications

According to the time series analyses presented here, an ongoing advance in plant phenology at this site is attributable to the accelerating decline in Arctic sea ice, and contributes to declining large herbivore reproductive performance via trophic mismatch.
Implications of Arctic Sea Ice Decline for the Earth System
- Environmental Science

Recommendations for effective AMM conservation are maintained and improved by local, federal, and international partners; recognize spatial and temporal variability in AMM subpopulation response to climate change; implement monitoring programs with clear goals; mitigate cumulative impacts of increased human activity; and recognize the limits of current protected species legislation.
Divergence of Arctic shrub growth associated with sea ice decline
- Environmental ScienceProceedings of the National Academy of Sciences

It is suggested that moisture limitation, associated with declining SIE, might inhibit the positive effects of warming on shrub growth over a considerable part of the terrestrial Arctic, thereby complicating predictions of vegetation change and future tundra productivity.
Northward Expansion and Intensification of Phytoplankton Growth During the Early Ice‐Free Season in Arctic

In the last decades, reduction of the ice cover has been documented to affect the structure and the functioning of Arctic marine ecosystems. One direct consequence is earlier phytoplankton spring…
A multi-proxy reconstruction of sea ice extent and primary productivity during Marine Isotope Stage 11 in the Bering Sea

The ongoing decline in Arctic sea ice extent has prompted concerns about the fate of sea ice in the future, and the stability of sea ice-dependent ecosystems. By studying the natural variability of…
Sea-ice induced growth decline in Arctic shrubs

Although the large scatter between individual model simulations leads to much uncertainty as to when a seasonally ice-free Arctic Ocean might be realized, this transition to a new arctic state may be rapid once the ice thins to a more vulnerable state.
Massive Phytoplankton Blooms Under Arctic Sea Ice

Evidence suggests that under-ice phytoplankton blooms may be more widespread over nutrient-rich Arctic continental shelves and that satellite-based estimates of annual primary production in these waters may be underestimated by up to 10-fold.
Reconstructed changes in Arctic sea ice over the past 1,450 years

A network of high-resolution terrestrial proxies from the circum-Arctic region is used to reconstruct past extents of summer sea ice, and shows that both the duration and magnitude of the current decline in sea ice seem to be unprecedented for the past 1,450 years.
