How a measure of tree structural complexity relates to architectural benefit‐to‐cost ratio, light availability, and growth of trees

Ecology and Evolution, 2019
Aboveground tree architecture is neither fully deterministic nor random. It is likely the result of mechanisms that balance static requirements and light‐capturing efficiency.

Variations in genetic diversity in cultivated Pistacia chinensis

Frontiers in Plant Science, 2022
Identification of the evolution history and genetic diversity of a species is important in the utilization of novel genetic variation in this species, as well as for its conservation.

Long-term effects of gap creation and liming on understory vegetation with a focus on tree regeneration in a European beech (Fagus sylvatica L.) forest

Annals of Forest Research, 2014
The long-term effects of gap creation and liming on tree regeneration and understory competition were examined in a mature European beech (Fagus sylvatica) stand on a nutrient-poor site.

Relationship between tree growth and physical dimensions of Fagus sylvatica crowns assessed from terrestrial laser scanning

iForest - Biogeosciences and Forestry, 2015
Measurements of physical tree crown dimensions were of subjective character in the past, even though they can be considered important for the management of many silvicultural operations, such as timing of thinning operations. In our study we investigated

Growth, morphology, and biomass allocation of recently planted seedlings of seven European tree species along a light gradient

iForest - Biogeosciences and Forestry, 2020
Light is one of the most critical factors controlling tree survival and growth. Limited light availability induces phenotypic plasticity, thus enabling plants to adapt to suboptimal conditions.

PypeTree: A Tool for Reconstructing Tree Perennial Tissues from Point Clouds

Sensors, 2014
The reconstruction of trees from point clouds that were acquired with terrestrial LiDAR scanning (TLS) may become a significant breakthrough in the study and modelling of tree development.

The Presence of IUCN Red List Tree Species in Dependence of Site Characteristics in the Vietnamese Cat Ba National Park

Diversity, 2020
Rare or endangered tree species are important components of forest ecosystems and play a crucial role in management and conservation. Understanding what influences their presence is critical for managers, conservationists and planners.

What does literature tell us about the relationship between forest structural attributes and species richness in temperate forests? – A review

Ecological Indicators, 2023
The effects of forest management on species richness and diversity have become important research interests. The need to maintain biodiversity for forest ecosystem functioning has led to the question of how strongly and in what ways forest management ...

Efficient measurements of basal area in short rotation forests based on terrestrial laser scanning under special consideration of shadowing

iForest - Biogeosciences and Forestry, 2014
Terrestrial laser scanning has been used in forest research for about ten years and use-orientated applications are of increasing importance. The effect of shadowing in single location laser scanning, e.g., as used for biomass estimations, has not been ...

Erysiphe magnoliicola Comprises the Powdery Mildew Found on Magnolia kobus in Korea

한국균학회지, 2022
The powdery mildew found on Magnolia kobus was recorded as Microsphaera alni for the first time in Korea in 1975. After splitting M. alni into several distinct species, this mildew was regarded as Microsphaera magnifica, now Erysiphe magnifica.
