Overstory–Understory Relationships
2013A key issue for sustainable management of oak woodlands is understanding the complex overstory-understory relationships that influence ecosystem productivity and stability. Oak removal is traditionally practiced in Californian ranches and Spanish oak dehesas to increase forage for grazing, but the response of the understory, and subsequently of the ...

Phenological Differences Between Understory and Overstory
2009The timing of phenological events varies both among species, and also among individuals of the same species. Here we use a 12-year record of spring and autumn phenology for 33 woody species at the Harvard Forest to investigate these differences. Specifically, we focus on patterns of leaf budburst, expansion, coloration and fall, in the context of ...

Oak regeneration and overstory density in the Missouri Ozarks
Canadian Journal of Forest Research, 1997Reducing overstory density is a commonly recommended method of increasing the regeneration potential of oak (Quercus) forests. However, recommendations seldom specify the probable increase in density or the size of reproduction associated with a given residual overstory density. This paper presents logistic regression models that describe this relation

Timing Overstory Removal in Longleaf Pine
Journal of Forestry, 1975Abstract In three studies with longleaf seedlings through 10 years of age, overstory competition sharply reduced growth. Stands developed most rapidly with early release (by seedling age 3), but even when release was delayed until age 8, seedlings responded well to overstory removal. The percent of any seedling stand in active height

The Mortality of Midwestern Overstory Oaks as a Bioindicator of Environmental Stress
Ecological Applications, 1999Tree mortality rates are potential indicators of the impact of environmental stresses on forests. But the relationship between environmental stress and tree mortality is poorly understood, particularly in forests not experiencing epidemic mortality.

Overstory spread and intensification of hemlock dwarf mistletoe
Canadian Journal of Forest Research, 1977Development of dwarf mistletoe (Arceuthobiumtsugense (Rosendahl) G.N. Jones) on 51 western hemlock (Tsugaheterophylla (Raf.) Sarg.) trees planted in 1963 at varying distances from an infected residual tree is described. Distribution of infections in the planted trees related directly to seed-dispersal patterns, i.e., it was influenced mainly by ...

[Understory effects on overstory trees: A review.]
Ying yong sheng tai xue bao = The journal of applied ecology, 2018Plant-plant interactions play a key role in regulating the composition and structure of communities and ecosystems. Studies of plant-plant interactions in forest ecosystems have traditionally concentrated on either tree-tree interactions or overstory species' impacts on understory plants.

Aspen forest overstory relations to understory production
2011We examined the relationship between aspen cover and understory production across two topographic positions and two management systems within the Aspen Parkland of eastern Alberta. Understory biomass typically declined with increasing overstory, with greater yield losses on north-facing forests than bottomlands.

2015
The Overstory, winner of the 2019 Pulitzer Prize in Fiction, is a sweeping, impassioned work of activism and resistance that is also a stunning evocation of―and paean to―the natural world. From the roots to the crown and back to the seeds, Richard Powers' twelfth novel unfolds in concentric rings of interlocking fables that range from antebellum New ...
