Schema of chronology of events relevant to the phenology of capelin.

<p>Somatic lipid contents of adult capelin (red line) [redrawn from Table 1 in 61], periods of capelin feeding and gonadal development (blue line) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087589#pone.0087589-Winters1" target="_blank">[62]</a>, timing of the spring bloom (green line) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087589#pone.0087589-Wu1" target="_blank">[37]</a>, timing of <i>Calanus finmarchicus</i> emergence from dormancy (pink line) <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0087589#pone.0087589-Johnson1" target="_blank">[71]</a>, timing of capelin spawning (orange) and timing of capelin acoustic survey (black line).</p

Study area.

<p>Capelin stock area, NAFO Divisions 2J3KL. The locations of St John’s, Bryant’s Cove, Bellevue Beach, Notre Dame Bay, and the <i>Atlantic Zone Monitoring Program (AZMP)</i> lines Seal Island and Bonavista are indicated.</p

Fit of the dome-shaped capelin biomass model.

<p>Open triangles denote capelin acoustic biomass estimates prior to 1991 and filled squares during the post 1990 period. Bars denote 95% confidence intervals. Note that y-axis is in logarithmic scale.</p

Relationship between biological variables, ice characteristics and “period”.

<p>Capelin and <i>Calanus finmarchicus</i> characteristics explained by ice properties and “period”. (A) Capelin biomass. (B) Timing of capelin peak spawning date at Bryant’s Cove and Bellevue Beach. (C) Abundance of adult <i>C. finmarchicus</i> (Calfin VI) on the Newfoundland-Labrador Shelf. Shaded portions indicate models forecasts and hindcast contrasted to independent data.</p

Climatic patterns.

<p>(A) 5-year running mean of air temperature anomalies in St John’s (red line) and 121-month smoothed Atlantic Multidecadal Oscillation (AMO) anomalies (from long term means), (B) Cumulative sums of air temperature anomalies in St John’s (red line) and Atlantic Multidecadal Oscillation anomalies (blue line). Shaded portions represent periods when regime shifts occurred.</p
