| Summary: | © springer-Verlag Berlin heidelberg (outside the usa) 2014 structure as well as an increase in reproductive output (R o ) and decrease in generation time (G o ). collectively, these results indicate arctic char populations (not just individuals) are extremely sensitive to small changes in the number of ice-free days. We hypothesize years with a longer growing season, predicted to occur more often under climate change, produce elevated growth rates of small char and act in a manner similar to a "resource pulse," allowing a subset of small char to "break through," thus setting the cycle in population structure. |
