Just The Facts
Did the overall findings support or reject the hypothesis?
The findings did not support hypothesis.
local populations showed higher survival & grew larger than foreign populations regardless of latitude & warming treatment
True or False: Factors aside from climate play no role in driving local adaptation?
False.
From observing local populations having a home site advantage, this indicates environmental factors could hinder establishment of southern immigrants in the Arctic.
Why were the plots warmed to a greater temperature in winter (3.3°C) vs. in summer (1.7 °C)?
High latitudes are predicted to experience substantial warming over the next century, with the bulk of warming occurring in the winter.
Which species, mountain sorrel or rooted poppy, showed the greatest among-population differences in the results?
The strongest among-population differences were found for mountain sorrel.
date of leaf-out and leaf senescence followed latitudinal trend while survival and growth demonstrated home-site advantage
True or False: warming treatment led to advanced senescence in both tested species?
False.
For rooted poppy: warmed treatment increased senescence in northern sites and had no effect south site.
For mountain sorrel: warming treatment was not significant
What does this study tell us about conservation methods in response to increasing climate?
In situ conservation methods can help address climate change by protecting ecosystems in their natural habitats, allowing species to adapt naturally to environmental shifts.
