Effects of grazing on the relationship between dominant shrubs and understory vegetation along sand dune stability gradient.

PLoS ONE
During the process of dune vegetation restoration, understanding how grazing disturbance affects the relationship between plant species is a critical issue in ecological studies.

Application of a novel schema for describing fossil fern foliage and investigating taxonomic and morphological change across the Cretaceous–Paleogene boundary in western North America

American Journal of Botany, EarlyView.
Abstract Premise The Chicxulub asteroid impact at the Cretaceous–Paleogene (K–Pg) boundary triggered a mass extinction 66 million years ago. Ferns thrived in the aftermath of the extinction, evidenced by the well‐documented “fern spore spike.” However, fern macrofossil records across the K–Pg boundary are less understood.

Processing and analysis of airborne full-waveform laser scanning data for the characterization of forest structure and fuel properties

Revista de Teledetección, 2020
This PhD thesis addresses the development of full-waveform airborne laser scanning (ALSFW) processing and analysis methods to characterize the vertical forest structure, in particular the understory vegetation.

An eye-tracking study on visual perception of vegetation permeability in virtual reality forest exposure

Frontiers in Public Health, 2023
Previous studies have confirmed the significant effects of single forest stand attributes, such as forest type (FT), understory vegetation cover (UVC), and understory vegetation height (UVH) on visitors' visual perception.

Environmentally induced dynamics between intraindividual variation and trait means across vegetative, phenological, and floral traits

American Journal of Botany, EarlyView.
Abstract Premise Intraindividual variation in reiterated structures (e.g., leaves) represents an important dimension of phenotypic variation that contributes to functional diversity and the dynamics of ecological communities. It can be expressed differently across plant traits, but how environmental drivers affect intraindividual variation in different

Comparative Assessment of Landsat‐8 and SPOT‐7 Satellite Data With Field Spectral Measurements for Estimating Plant Diversity in Sandy Grasslands

Biological Diversity, EarlyView.
We compared Landsat‐8 OLI, SPOT, and hyperspectral data for estimating vascular plant diversity in China's Hunshandak Sandland. SPOT data showed the strongest correlation with alpha diversity, followed by hyperspectral data, with Landsat‐8 performing the weakest.

Effect of stand types on understory vegetation.

Journal of environmental biology, 2009
The objective of this study was to compare density vegetative cover, basal area, height growth, aboveground biomass production, frequency floristic composition, and species diversity of understory vegetation growing in Hungarian oak (Quercus frainetto Ten.), Oriental beech (Fagus orientalis L.) and a mixed stand of both species (90% Hungarian oak and ...

Understory vegetation as environmental factors indicator in forest ecosystems [PDF]

International Journal of Environmental Science & Technology, 2010
Physiographic factors along with edaphic conditions play a crucial role in establishment of plant species throughout a region. Identification of the most effective factors is of high importance in sustainable management of a forest ecosystem. This study aims to investigate the relationships between understory vegetation and some environmental factors ...

Differential Elevational Diversity Between Overstory and Understory in Tropical Forests

Biological Diversity, EarlyView.
Tropical forest overstory and understory exhibit contrasting elevational α‐diversity patterns (unimodal vs. bimodal). Community differentiation is driven by species turnover of dominant rather than rare species, highlighting the need for vertically stratified conservation across the full elevational gradient.

The Effect of Multinutrient Fertilization on Understory Vegetation Annual Production [PDF]

Western Journal of Applied Forestry, 2002
Abstract This study quantified the effects of operational multinutrient fertilization on understory shrub, forb, and grass production in inland Northwest forests. Understory vegetation annual production increased at some sites while other sites showed no change or decreases following fertilizer treatments.
