“…The unpredictability may be caused by variability in temperature which again may influence quality of the main food item Mytilus spp. (Bayne and Widdows, 1978;Waldeck and Larsson, 2013) as well as food conversion (e.g. Brett, 1979).…”

Anthropogenic impact on the environment and wildlife are multifaceted and far-reaching. On a smaller scale, controlling for predators has been increasing the yield from local natural prey resources. Globally, human-induced global warming is expected to impose severe negative effects on ecosystems, an effect that is expected to be even more pronounced in the scarcely populated northern latitudes. The clearest indication of a changing Arctic climate is an increase in both air and ocean temperatures leading to reduced sea ice distribution. Population viability is for long-lived species dependent on adult survival and recruitment. Predation is the main mortality cause in many bird populations, and egg predation is considered the main cause of reproductive failure in many birds. To assess the effect of predation and climate, we compared population time series from a natural experiment where a trapper/down collector has been licensed to actively protect breeding common eiders Somateria mollissima (a large seaduck) by shooting/chasing egg predators, with time series from another eider colony located within a nature reserve with no manipulation of egg predators. We found that actively limiting predator activity led to an increase in the population growth rate and carrying capacity with a factor of 3–4 compared to that found in the control population. We also found that population numbers were higher in years with reduced concentration of spring sea ice. We conclude that there was a large positive impact of human limitation of egg predators, and that this lead to higher population growth rate and a large increase in size of the breeding colony. We also report a positive effect of warming climate in the high arctic as reduced sea-ice concentrations was associated with higher numbers of breeding birds.

“…Based on abundance at least, Blue Mussels have not been in short supply in the core area experiencing the most steep decline in Common Eiders, and hence likely not an issue. There is no indication that Blue Mussel quality as food for the birds in any way would have been changing for the worse in the core breeding area of the Common Eider in Finland (see Larsson & Waldeck 2013). In the central part of the Gulf of Finland, on the other hand, Blue Mussel abundance may have played a part initially in the low production of young.…”

“…As summarized by Ottvall (2012) populations of Blue Mussels off Gotland may have been stable, while some data indicate that they have decreased in parts of the Stockholm archipelago. While it seem reasonably clear that mussel quality may vary between years due to effects on mussel condition (Larsson & Waldeck 2013) it is not clear that mussels per se would have a direct effect on breeding Eiders. On a qualitative basis, Blue Mussels off the Finnish coast are, however, more abundant than off Gotland (K. Larsson, pers.…”
