Climate sensitivity of understory trees differs from overstory trees in temperate mesic forests.

Ecology, 2020
The response of understory trees to climate variability is key to understanding current and future forest dynamics. However, analyses of climatic effects on tree growth have primarily focused on the upper canopy, leaving understory dynamics unresolved ...

Overstory Retention and Stock Type Impact Survival and Growth of Underplanted Shortleaf Pine Beneath a Hardwood Canopy

, 2021
This study was established to evaluate underplanting as a method of reestablishing a shortleaf pine (Pinus echinata Mill.) component to a dry upland hardwood stand in the Piedmont region of the southeastern United States.

Overstory

2023
Abstract This epilogue reflects on the career and character of the Buddha by presenting and analyzing an episode from the end of his life story. This recounts his feat of clearing away a great boulder blocking the road he is taking to get to Kuśinagarī which the Malla strongmen are having difficulty removing. The tale has many dimensions:

C:N:P stoichiometry of rhizosphere soils differed significantly among overstory trees and understory shrubs in plantations in subtropical China

Canadian Journal of Forest Research, 2018
Rhizosphere soil C:N:P stoichiometry is useful for identifying the linkage of plant species and soil nutrients, which can be particularly helpful for understory vegetation management of forest ecosystems.

Overstory–Understory Relationships

2013
A 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 ...

An Overstory for Our Time

American Literature, 2020
AbstractCare is the intimate and necessary labor required to sustain those who are dependent, but it is also about acting in ways that sustain other species and the lives of strangers distant in time and space. The COVID-19 pandemic shines a spotlight on the vulnerabilities and gaps in global care networks.

Overstory Attributes, Light, Throughfall, and the Interpretation of Overstory-Understory Relationships

Forest Science, 1978
Abstract This study examines basal area and three measures of canopy cover as predictors of both throughfall and light in an Arizona ponderosa pine forest. Overhead canopy cover, as measured with canopy photographs, accounted for the largest proportion of the variance in throughfall.

Phenological Differences Between Understory and Overstory

2009
The 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 ...

Seed rain of ponderosa pine beneath partial overstories

New Forests, 2007
An analysis was conducted of the 1999 ponderosa pine (Pinus ponderosa var. ponderosa Dougl. ex Laws.) seed crop at two stands of differing overstory density in each of two sites that differed in productivity (forest community series) on the east slope of the Cascade Range in central Oregon, USA.
