Parsing the Relative Contributions of Leaf and Canopy Traits in Airborne Spectrometer Measurements

Remote Sensing
Forest canopy near-infrared reflectance and mass-based canopy nitrogen concentration (canopy %N) have been shown to be positively correlated. While the mechanisms underpinning this relationship remain unresolved, the broad range of wavelengths involved ...

Estimating Three-Dimensional Distribution of Leaf Area Using Airborne LiDAR in Deciduous Broad-Leaved Forest

Remote Sensing, 2023
We examined the performance of airborne light detection and ranging (LiDAR) data obtained in 2011 for leaf area estimation in deciduous broad-leaved forest using the Beer–Lambert law in Takayama, Gifu, Japan.

Influence of Leaf Area Index Prescriptions on Simulations of Heat, Moisture, and Carbon Fluxes [PDF]

, 2014
Leaf-area index (LAI), the total one-sided surface area of leaf per ground surface area, is a key component of land surface models. We investigate the influence of differing, plausible LAI prescriptions on heat, moisture, and carbon fluxes simulated by ...

The effect of light availability and spatio‐temporal heterogeneity on the soil seed bank diversity in temperate forests

Oikos, EarlyView.
Light is a key driver of understory plant diversity, also important for seed germination, yet its effect on forests soil seed bank diversity remains underexplored. This study assessed the impact of both light availability and spatio‐temporal heterogeneity on soil seed bank diversity.

A comparison of optical and direct methods for monitoring the seasonal dynamics of leaf area index in deciduous forests

Silva Fennica, 2001
During the 1996 growing season the seasonal dynamics of the Leaf Area Index (LAI) were determined by 3 different methods in two forest types: a mixed oak (Quercus robur L.) – beech (Fagus sylvatica L.) stand and an ash dominated (Fraxinus excelsior L.)

Plant Development and Leaf Area Production in Contrasting Cultivars of Maize Grown in a Cool Temperate Environment in the Field [PDF]

, 2003
Crop models need accurate simulation of the interdependent processes of crop development and leaf area production. Crop development proceeds according to genotype characteristics and environmental influences, specifically temperature and photoperiod.

Novel applications of the tomato microbiome: Roles and considerations for agriculture, human health, and society

PLANTS, PEOPLE, PLANET, EarlyView.
Plants, like humans, have a microbiome that helps them grow, defend themselves against pathogens, acquire nutrients, and protect themselves against environmental stresses. The microbiome of tomatoes, a staple crop grown worldwide, could be utilized not only to reduce fertilizer and pesticide applications, but also to clean up harmful pollutants ...

Multi-Crop Green LAI Estimation with a New Simple Sentinel-2 LAI Index (SeLI)

Sensors, 2019
The spatial quantification of green leaf area index (LAIgreen), the total green photosynthetically active leaf area per ground area, is a crucial biophysical variable for agroecosystem monitoring.

A proposed methodology for the correction of the Leaf Area Index measured with a ceptometer for pinus and eucalyptus forests = Proposta de uma methodologia para a correcao do indice de area foliar medido pelo ceptometro em provoamentos de pinus e eucalyptus [PDF]

, 2016
Leaf area index (LAI) is an important parameter controlling many biological and physiological processes associated with vegetation on the Earth's surface, such as photosynthesis, respiration, transpiration, carbon and nutrient cycle and rainfall ...

Land data assimilation of satellite‐based surface soil moisture: Impact on atmospheric simulations over the contiguous United States

Quarterly Journal of the Royal Meteorological Society, EarlyView.
Soil Moisture Active Passive soil moisture retrievals are assimilated into a land surface model and the resulting land reanalysis product is used to initialise the land component of coupled land‐atmosphere experiments. We show that the local impact of land data assimilation on the atmosphere is influenced by two factors: the magnitude by which it ...
