Header Card Description: Kuinka pitkän talven koivu tarvitsee ja millaisen talven? Miten koivu hoksaa talven tulon jo heinäkuussa? Elokuussa, kun päivä lyhenee, se jo väsää talvehtimissilmuja. Talven heittelehtivät lämpötilat eivät koivua hämää, sillä se laskee talvipäiviä. Lisäksi koivu on vuosituhansien aikana sopeutunut siihen, että lämpimiin talvipäiviin ei voi luottaa, mutta päivänvaloon voi. Kevättä odotellessa koivu mittaa lämpötiloja ja laskee talvipäiviä. Koivun ja fiikuksen eroja vertailevat professori Kurt Fagerstedt ja Leena Mattila.
