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.

Global patterns and climatic controls of forest structural complexity

Nature Communications, 2021
Forest structure depends both on extrinsic factors such as climate and on intrinsic properties such as community composition and diversity. Here, the authors use a dataset of stand structural complexity based on LiDAR measurements to build a global map ...

Global patterns of woody residence time and its influence on model simulation of aboveground biomass [PDF]

, 2017
Woody residence time (τw) is an important parameter that expresses the balance between mature forest recruitment/growth and mortality. Using field data collected from the literature, this study explored the global forest τw and investigated its influence

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.

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 ...

Interactions between carbon and nitrogen dynamics in estimating net primary productivity for potential vegetation in North America [PDF]

, 1992
We use the terrestrial ecosystem model (TEM), a process-based model, to investigate how interactions between carbon (C) and nitrogen (N) dynamics affect predictions of net primary productivity (NPP) for potential vegetation in North America. Data on pool

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.

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.
