Although spatial patterns of seed distribution are thought to vary greatly among plant species dispersed by different vectors, few studies have directly examined this assumption. We compared patterns of seed rain of nine species of trees disseminated

Quantification of seed rain patterns is an initial step toward explaining variation in plant recruitment, and consequently, organization of forest communities. Spatially contagious patterns of seed deposition, where seeds are patchily dispersed with

This study deals with the disturbance regime of an old-growth, mixed-evergreen forest with a canopy composed of Arbutus menziesii, Lithocarpus densiflora, Pseudotsuga menziesii, Quercus chrysolepis, Q. wislizenii, and Sequoia sempervirens. 80 canopy

Most tropical plants produce fleshy fruits that are dispersed primarily by vertebrate frugivores. Behavioral disparities among vertebrate seed dispersers could influence patterns of seed distribution and thus forest structure. This study investigated

Members of the chaparral genus Arctostaphylos regenerate after fires either by obligate seeding or facultative sprouting. To test the hypothesis that sprouting species differ from nonsprouting species, we compared flower, fruit and seed production an

Wyethiamollis Gray (Asteraceae) dominates extensive areas within the mixed conifer forest of the eastern Sierra Nevada, California. Large (>20 ha) patches form when overgrazing follows canopy fires. No regeneration of conifers is found in these patch

A B S T R A C T Study of seed banks, field seedling emergence, and survival of macrophytes in four zones (steep bank-SB; gentle bank-GB; midbank-MB; high marsh-HM) along transects perpendicular to a stream channel in a freshwater tidal wetland showed

A 1977 wildfire destroyed a Pinus jeffreyi forest on the east slope of the northern Sierra Nevada. The area was replanted with 1-yr seedlings of P. jeffreyi. Survival and growth of P. jeffreyi seedlings were determined after 5 and 8 yr in patches dom
