Facilitative and competive effects of a N-fixing shrub on white fir saplings

Creator:: Oakley, Brian B., North, Malcolm P., and Franklin, Jerry F.
Abstract:: In Sierra Nevada forests, shrubs are considered strong soil moisture competitors with regenerating trees, reducing seedling establishment, and slowing growth. Recent studies, however, suggest that in some circumstances shrubs can facilitate tree establishment and growth by modifying harsh microclimate conditions; increasing acquisition of water, carbon, and/or nutrients via shared mycorrhizal...

The effects of fire on soil nitrogen associated with patches of the actinorhizal shrub Ceanothus cordulatus

Creator:: Oakley, Brian B., North, Malcolm P., and Franklin, Jerry F.
Abstract:: Nitrogen is a limiting resource in many temperate forests and nitrogen-fixing plants are usually limited to the early stages of post-disturbance succession. In fire-dependent Sierra Nevada forests, however, Ceanothus cordulatus is relatively abundant even in old-growth forest conditions which are at least partly maintained by fire.We conducted a field experiment...

Influence of light and soil moisture on Sierran mixed-conifer understory communities

Creator:: North, Malcolm, Oakley, Brian, Fiegener, Rob, Gray, Andrew, and Barbour, Michael
Abstract:: Sierra Nevada forests have high understory species richness yet we do not know which site factors influence herb and shrub distribution or abundance. We examined the understory of an old-growth mixed-conifer Sierran forest and its distribution in relation to microsite conditions. The forest has high species richness (98 species sampled),...

Diversity and distribution of Frankia strains symbiotic with Ceanothus in California

Creator:: Oakley, Brian, North, Malcolm, Franklin, Jerry F., Hedlund, Brian P., and Staley, James T.
Abstract:: Frankia strains symbiotic with Ceanothus present an interesting opportunity to study the patterns and causes of Frankia diversity and distribution within a particular host infectivity group. We intensively sampled Frankia from nodules on Ceanothus plants along an elevational gradient in the southern Sierra Nevada of California, and we also collected...

Estimates of heterosis in winter/winter, winter/spring, and spring/spring crosses of barley (Hordeum vulgare L.)

Creator:: Oakley, Stephen Roland
Abstract:: Previous work indicated a substantial heterotic expression for grain yield existed within winter/spring hybrids of barley, This research was a continuation for the comparison of the expression of heterosis within winter/spring hybrids to the heterotic effect produced among the winter and among the spring parents. The F₁ and F₂ progenies...

Maximizing urban property values through open space conservation

Creator:: Oakley, Winston
Abstract:: This study investigates the share of open space that maximizes total private property values in urban areas. Open space poses a number of trade-offs to city managers. On the one hand, previous studies have shown that certain kinds of open space can increase property values, which tends to increase tax...
