LiDAR Characterization of Boreal Understory

open access: yes, 2021
The understory vegetation layer contributes considerably to the physical structure of boreal forests. This research sought to understand the relationships between field- and LiDAR- (light detection and ranging-) derived measures of boreal understory ...

Dryland management regimes alter forest habitats and understory arthropod communities [PDF]

open access: yes, 2018
Dryland forests, those characterised as having low precipitation and soil nutrients, account for over a quarter of forests globally. Increasing their productivity often relies on irrigation and fertilisation, but the impacts on the wider habitat are ...

Net Ecosystem Exchange of CO2 in Deciduous Pine Forest of Lower Western Himalaya, India

open access: yesResources, 2019
Carbon cycle studies over the climate-sensitive Himalayan regions are relatively understudied and to address this gap, systematic measurements on carbon balance components were performed over a deciduous pine forest with an understory layer.

The effects of stand characteristics on the understory vegetation in Quercus petraea and Q. cerris dominated forests [PDF]

open access: yes, 2013
The shelterwood system used in Hungary has many effects on the composition and structure of the herb layer. The aim of our study was to identify the main variables that affect the occurence of herbs and seedlings in Turkey oak-sessile oak (Quercus cerris

The influence of leaf characteristics on epiphyllic cover : a test of hypotheses with artificial leaves [PDF]

open access: yes, 1995
Studies of epiphyll ecology have been hindered by the biochemical and morphological variability of the leaf substrate. The use of artificial (plastic ribbon tape) leaves solved that problem in a study done at the Braulio Carrillo National Park, Costa ...

Estimating aboveground live understory vegetation carbon in the United States

open access: yesEnvironmental Research Letters, 2017
Despite the key role that understory vegetation plays in ecosystems and the terrestrial carbon cycle, it is often overlooked and has few quantitative measurements, especially at national scales.

Changes in the structure and productivity of a herb-Sphagnum pine stand upon drainage and a combination of treatments

open access: yesTransactions of the Karelian Research Centre of the Russian Academy of Sciences, 2018
Data from long-term (30 yrs) monitoring of changes in the ecological conditions and species composition of all vegetation layers (tree stand, young growth, undergrowth, dwarf shrub-herb layer, moss layer) of a drained herb-sphagnum pine stand after a ...

Rapid Increases in Forest Understory Diversity and Productivity following a Mountain Pine Beetle (Dendroctonus ponderosae) Outbreak in Pine Forests [PDF]

open access: yes, 2015
The current unprecedented outbreak of mountain pine beetle (Dendroctonus ponderosae) in lodgepole pine (Pinus contorta) forests of western Canada has resulted in a landscape consisting of a mosaic of forest stands at different stages of mortality. Within

Site and soil drivers of growth and ginsenoside accumulation in forest-grown ginseng

open access: yesJournal of Agriculture and Food Research
Forest-grown ginseng (Panax ginseng C. A. Mey.) is widely valued for its high medicinal quality; however, the ecological factors governing plant growth and ginsenoside accumulation under natural forest ecosystems remain insufficiently understood.
