Growth data for young of the year arctic grayling raised in a aquatic common garden at Toolik Field Station, summer 2017

| Summary: | Since 2009, the FISHSCAPE Project (Grant #1719267, 1417754, and 0902153), based at Toolik Field Station, has monitored physical, chemical, and biological parameters within three watersheds: The Kuparuk (including Toolik Lake and Toolik outlet stream); The Sagavanirktok (primarily Oksrukuyik Creek, but also including sections of the Ailish and Atigun Rivers and the Galbraith Lakes); and The Itkillik (primarily the I-Minus outlet stream, a tributary that that feeds into the Itkilik River). The goals are to understand and predict the adaptability and persistence of a key Arctic species, the Arctic grayling (Thymallus arcticus), to changing climate and hydrology. Research questions include: (1) Does landscape structure determine movement within and among watersheds; (2) do populations adapt to stream characteristics at local and regional scales; and (3) will the relative adaptability of populations determine their persistence under future climate change. To test ideas about local adaptation, we conducted an aquatic common garden experiment at Toolik Field Station, to investigate the genetic component of phenotypic variation among Arctic grayling populations on Alaska's North Slope. This file contains the growth data. |
