Our primary objective was to examine the distributions of herbs and shrubs/trees along local topographic gradients in headwater regions of longleaf pine savannas in the southeastern United  States.  We also examined whether herb patterns were structurally similar to those of shrubs/trees along the same topographic gradients and whether patterns were correlated with edaphic factors.  Abundance data were collected within quadrats placed along transects from upslope savannas through mid-slope seepage bogs into lower-slope shrub/tree zones within Louisiana and Florida.  Beta-flexible cluster analysis and nonmetric multidimensional scaling were used to delineate herbaceous species communities.  Ordination was performed separately on shrub/tree abundance  data.  The herb-based classifications were also used to delineate shrub/tree communities, providing an indirect means of comparing herb to shrub/tree distributions.  In Louisiana, 3 herbaceous communities were sharply delineated along elevation gradients of several meters and were strongly correlated with soil moisture.  In Florida, 3 similar herbaceous communities were less discrete along elevation gradients of &lt;1 meter.  In both regions, shrub/tree distributions were much broader and appeared less sensitive than herbs to changes in environmental gradients. Coefficients of variation indicated that herbaceous species were more narrowly distributed than shrubs/trees along localized elevation gradients in both Louisiana and Florida.  Alterations of fire regimes may have resulted in expanded distributions of shrubs/trees but not herbs.</style></abstract><accession-num><style face="normal" font="default" size="100%">LTER.2002-90904</style></accession-num></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">Drewa, P.

We examined effects of fire season and frequency, geography, habitat, and underground organ morphology on resprouting of shrubs in upslope savannas and downslope seepages in Louisiana and Florida.  Each site contained quadrats located  along transects within a 30m x 60m plot, was burned during the dormant or growing season and reburned similarly 2 years later. Maximum fire temperatures were measured and densities of shrub stems censused in quadrats before and after fires.  Shrubs collectively resprouted more after dormant rather than growing season fires, regardless of habitat or geographic region. After repeated dormant season fires, collective densities in seepages of both regions and densities of root crown-bearing shrubs in Florida seepages were greater than those initially and after  repeated growing season fires. Shrub responses were generally unrelated to fire temperatures, supporting the hypothesis that resprouting of shrubs may be more dependent on their physiological status at the time of fires. There was an inverse relationship between collective and root-crown bearing shrub densities following repeated fires and maximum fire temperatures in Florida seepages. Anthropogenic dormant season fires over many decades may have resulted in increases in shrub densities in longleaf pine savannas, especially seepages. Repeated growing season fires neither increased nor reduced densities of established shrubs. Long-term shifts in characteristics of fire regimes may produce short-term (&lt;10 yrs), irreversible effects by reintroducing prescribed fires resembling naturally occurring ones during the growing season.</style></abstract><accession-num><style face="normal" font="default" size="100%">LTER.2002-90925</style></accession-num></record></records></xml>
