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.

Back to Roots: The Role of Ectomycorrhizal Fungi in Boreal and Temperate Forest Restoration

Frontiers in Forests and Global Change, 2020
Temperate and boreal forests are increasingly suffering from anthropic degradation. Ectomycorrhizal fungi (EMF) are symbionts with most temperate and boreal forest trees, providing their hosts with soil nutrients and water in exchange for plant carbon ...

Carbon fluxes in a mature deciduous forest under elevated CO₂ [PDF]

, 2010
This PhD thesis addressed several major aspects of the carbon (C) cycle in a c. 100-year-old, mixed deciduous forest under elevated CO₂ with an emphasis on below-ground processes.

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.

SMAP Detects Soil Moisture Under Temperate Forest Canopies

Geophysical Research Letters, 2020
Soil moisture dynamics in the presence of dense vegetation canopies are determinants of ecosystem function and biogeochemical cycles, but the capability of existing spaceborne sensors to support reliable and useful estimates is not known.

Distribution of the timber quality attribute ‘knot surface’ in logs of Fagus sylvatica L. from pure and mixed forest stands

, 2023
Research on mixed forests has mostly focused on tree growth and productivity, or resistance and resilience in changing climate conditions, but only rarely on the effects of tree species mixing on timber quality. In particular, it is still unclear whether

Divergent drivers of the microbial methane sink in temperate forest and grassland soils

Global Change Biology, 2020
Aerated topsoils are important sinks for atmospheric methane (CH4) via oxidation by CH4‐oxidizing bacteria (MOB). However, intensified management of grasslands and forests may reduce the CH4 sink capacity of soils.

Controls on winter ecosystem respiration in temperate and boreal ecosystems [PDF]

, 2011
Winter CO2 fluxes represent an important component of the annual carbon budget in northern ecosystems. Understanding winter respiration processes and their responses to climate change is also central to our ability to assess terrestrial carbon cycle and ...

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 ...
