Retrieving the Leaf Area Index of Dense and Highly Clumped Moso Bamboo Canopies from Sentinel-2 MSI Data

Remote Sensing
The effects of leaf clumping on leaf area index (LAI, m2·m−2) retrieval have been proved by several studies. For dense and highly clumped Moso bamboo canopies, LAI is usually retrieved using the SAIL-series models that do not account for leaf clumping ...

Measurement and modelling litter biomass and leaf area index using allometry in a Beech-Hornbeam stand in the mid-elevation of the Hyrcanian region, Iran [PDF]

تحقیقات جنگل و صنوبر ایران, 2014
Litter biomass and leaf area index (LAI) are two important attributes which play crucial roles on the biological processes which impact forest productivity, including photosynthesis, water and nutrient cycles.

Tight coupling of leaf area index to canopy nitrogen and phosphorus across heterogeneous tallgrass prairie communities [PDF]

, 2016
Nitrogen (N) and phosphorus (P) are limiting nutrients for many plant communities worldwide. Foliar N and P along with leaf area are among the most important controls on photosynthesis and hence productivity.

Wildfires' Cost for Societal Welfare: Economic Evaluation of Forestry Ecosystem Services Losses in Southern Italy

Land Degradation &Development, EarlyView.
ABSTRACT Forest ecosystem services (ESs) are garnering increasing public attention as awareness grows regarding society's fundamental dependence on them for well‐being. Forest fires, one of the major disturbances of ESs, are becoming more frequent and destructive, exacerbated in part by climate change.

New insights of global vegetation structural properties through an analysis of canopy clumping index, fractional vegetation cover, and leaf area index

Science of Remote Sensing, 2021
Canopy clumping index (CI), fractional vegetation cover (FVC), and leaf area index (LAI) are important vegetation structural variables. Characterization of the spatial and temporal variations of these variables is important for understanding the global ...

Inconsistencies of interannual variability and trends in long-term satellite leaf area index products [PDF]

, 2017
Understanding the long-term performance of global satellite leaf area index (LAI) products is important for global change research. However, few effort has been devoted to evaluating the long-term time-series consistencies of LAI products.

Recurrent drought amplifies drought impacts and increases seasonal synchrony in mountain grassland communities

Oikos, EarlyView.
Climate change increases the recurrence of drought events with strong repercussions on grassland ecosystems. While the effects of single drought events on ecosystem structure and functioning are well understood, it is largely unknown whether and how recurrent drought events modify ecosystem responses to subsequent drought.
