The importance of biomass net uptake for a trace metal budget in a forest stand in north-eastern France [PDF]

open access: yes, 2010
The trace metal (TM: Cd, Cu, Ni, Pb and Zn) budget (stocks and annual fluxes) was evaluated in a forest stand (silver fir, Abies alba Miller) in north-eastern France.

A Global Methane Observation System to Reduce Uncertainty for Anthropogenic and Natural Sources and Sinks for Detecting and Attributing Climate Feedbacks

open access: yesAdvanced Science, EarlyView.
Conceptual illustration of a Global Ecosystem Methane Observing System (GEM‐OS) integrating satellites, aircraft, atmospheric networks, and ecosystem measurements to quantify methane emissions from anthropogenic and natural sources. The multi‐scale observing framework improves source attribution, reduces uncertainty in regional methane budgets, and ...

Measuring rainfall to a forest canopy: an assessment of the performance of canopy level raingauges [PDF]

open access: yesHydrology and Earth System Sciences, 2004
Accurate rainfall measurements are crucial for water resource and environmental assessments but can be difficult to achieve in extensive areas of forest. This paper reviews the different techniques for measuring rainfall to a forest area and presents

Effect of stand density, canopy leaf area index and growth variables on Dendrocalamus brandisii (Munro) Kurz litter production at Simao District of Yunnan Province, southwestern China

open access: yesGlobal Ecology and Conservation, 2020
Litterfall is the primary interface between the forest canopy and forest floor for efficient carbon and nutrient cycling. However, there is limited knowledge on factors that influence D. brandisii litter production and its seasonal dynamics.

Drought Stress Mediated Changes in Food Crops: Mechanisms and Remediation Strategies

open access: yesAdvanced Science, EarlyView.
This work presents a multi‐scale framework for flavonoid‐mediated drought tolerance in staple food crops, integrating ROS redox regulation, antioxidant defense, rhizosphere microbial interactions, and sustainable agronomic practices. This interdisciplinary model provides core insights to develop climate‐resilient cropping systems and enhance global ...

The influence of the forest canopy on nutrient cycling [PDF]

open access: yesTree Physiology, 2002
Rates of key soil processes involved in recycling of nutrients in forests are governed by temperature and moisture conditions and by the chemical and physical nature of the litter. The forest canopy influences all of these factors and thus has a large influence on nutrient cycling.

Simultaneous HONO measurements in and above a forest canopy: influence of turbulent exchange on mixing ratio differences [PDF]

open access: yesAtmospheric Chemistry and Physics, 2011
We have combined chemical and micrometeorological measurements to investigate the formation and distribution of HONO throughout a forest canopy. HONO was measured simultaneously at two heights, close to the forest floor and just above canopy.
