If current temperature trends continue and increase as predicted by general circulation models, the persistence and migration of sugar maple (Acer saccharum) at its northern limit will become crucial to its continued existence in North America. Specifically, anthropogenic warming may affect germination success and growth of sugar maple. To evaluate this potential limitation, the AA. address 2 questions. The first involves a growth chamber: Do temperatures at and above (1°, 7°, and 14° C) sugar maple's optimal germination temperature affect its germination? The second involves a common garden: Do sugar maple germination and subsequent growth and mortality rates show evidence of geographic variation under current climatic conditions?
