Cytotype Distribution

Chromosome number determinations were made from 218 populations of Solidago nemoralis collected throughout the range of the species in Canada and the United States. All individuals of ssp. decemflora were tetraploid (2n = 36; 28 populations); these came from the prairies and adjacent eastern deciduous forest states and provinces. The majority of the collections of ssp. nemoralis were diploid (2n = 18; 161 populations) and came from throughout the eastern deciduous forest region of eastern North America. Tetraploids (2n = 36; 29 populations) of ssp. nemoralis were less frequent and occurred scattered across the eastern and northern portions of the range of the subspecies. The cytotype distribution pattern of the two subspecies of Solidago nemoralis is representative of what appears to be a frequent evolutionary strategy in the goldenrods.

History Of

AbstractNonconnah Creek, located in the loess-mantled Blufflands along the eastern wall of the Lower Mississippi Alluvial Valley in Tennessee displays a sedimentary sequence representing the Altonian Substage through the Woodfordian Substage of the Wisconsinan Stage. The site has a biostratigraphic record for the Altonian and Farmdalian Substages that documents warm-temperate upland oak-pine forest, prairie, and bottomland forest. At 23,000 yr B.P., white spruce and larch migrated into the Nonconnah Creek watershed and along braided-stream surfaces in the Mississippi Valley as far as southeastern Louisiana. The pollen and plant-macrofossil record from Nonconnah Creek provides the first documentation of a full-glacial locality in eastern North America for beech, yellow poplar, oak, history, black walnut, and other mesic deciduous forest taxa. During the full and late glacial, the Mississippi Valley was a barrier to the migration of pine species, while the adjacent Blufflands provided a refuge for mesic deciduous forest taxa. Regional climatic amelioration, beginning about 16,500 yr B.P., is reflected by increases in pollen percentages of cooltemperate deciduous trees at Nonconnah Creek. The demise of spruce and jack pine occurred 12,500 yr B.P. between 34° and 37° N in eastern North America in response to postglacial warming.

AbstractRecent pollen and macrofossil data from the Southeast is consistent with a displacement of boreal forest species by over 1000 km during full-glacial time. Data from west of the Appalachians suggests a displacement of some 600 km. Thus boreal forests were developed in a broad area south of the ice margin. Few deciduous forest elements persisted in that region. The displacement appears to have been azonal. There is good evidence to suggest a significant mid-Wisconsin interstadial (23,000-36,000 BP) characterized by a more temperate biota.
