Partitioning overstory and understory evapotranspiration in a semiarid savanna woodland from the isotopic composition of water vapor [PDF]
Agricultural and Forest Meteorology, 2003 The relative contributions of overstory and understory plant transpiration and soil evaporation to total evapotranspiration (ET) in a semiarid savanna woodland were determined from stable isotope measurements of atmospheric water vapor. The savanna overstory was dominated by the deeply rooted, woody legume Prosopis velutina (“mesquite”), and the ...

Understory vegetation plays a critical role in boreal ecosystems. Despite this, quantitative evaluation of the factors controlling understory vegetation abundance, diversity, and composition in the most diverse boreal forest region in North America is lacking. This study examined the dynamics of understory vegetation of stands of fire origin and tested

Ecosystems, 2018 Wildfire is the primary abiotic disturbance in the boreal forest, and its long-term absence can lead to large changes in ecosystem properties, including the availability and cycling of nutrients. These effects are, however, often confounded with the effects of successional changes in vegetation toward nutrient-conservative species.

Ground-flora and overstory composition and abundance patterns in 76 upland forest stands were related to the glacial geomorphology of a five-county area in northwestern lower Michigan. Nine classes of landforms were identified based on parent material and surface configuration.

Abstract Higher hardwood content in stands results in lower defoliation of overstory balsam fir (Abies balsamea (L.) Mill.) caused by spruce budworm (Choristoneura fumiferana Clem.). To determine whether higher overstory hardwood content also reduced defoliation and mortality of balsam fir regeneration of varying height classes during a spruce ...

Abstract. Patterns of understory colonization by native and naturalized trees and shrubs were evaluated in 4.5‐year‐old plantations of three exotic tree species, Casuarina equisetifolia, Eucalyptus robusta, and Leucaena leucocephala, on a degraded coastal grassland site with reference to overstory composition and understory environmental conditions ...

Multifactor ecological classification systems are being developed for many regions. An element of these systems not yet well understood is how disturbances, clearcutting in this instance, may alter the vegetative component of the classification units at the stand and landscape levels.
