Abstract
Recent studies show that forest herbs have low sexual reproductive efforts (SRE) and high vegetative reproductive efforts (VRE) and that a variety of factors may affect the levels of reproduction and the distribution patterns of forest species. Aster acuminatus is a micro-successional forest herb common in northern New England. Resource allocation patterns were determined for seven aster patches varying in density and light level. Plant density affects neither plant size nor any aspect of resource allocation, and VRE remains constant over all density and light levels. Light level is, however, significantly correlated with patch location, average plant size and average patch SRE. Only large plants produce flowers suggesting that light affects sexual reproduction indirectly through effects on plant size. The high rhizome and low seed survivorship of this species may partly explain the constant VRE and varying SRE levels, although the resource allocation patterns observed do not correspond well with the predictions of certain theoretical models.
