Interacting leaf dynamics and environment to optimize maize sowing date in North China Plain

open access: yesJournal of Integrative Agriculture, 2020
Leaf growth and its interaction with the growing environment critically affect leaf area, distribution, and function, and ultimately affects grain yield of maize (Zea mays L.).

Effects of Mechanical Transplanting Methods and Planting Geometry on Yield Formation and Canopy Structure of Indica Rice under Rice-Crayfish Rotation

open access: yesAgriculture, 2022
The rice–crayfish continuous production system developed rapidly due to its high economic benefits and eco-friendly nature in China. This study explored the effects of mechanically transplanted methods and planting geometry on the relationship between ...

Incorporating canopy structure from simulated GEDI lidar into bird species distribution models

open access: yesEnvironmental Research Letters, 2020
The Global Ecosystem Dynamics Investigation (GEDI) lidar began data acquisition from the International Space Station in March 2019 and is expected to make over 10 billion measurements of canopy structure and topography over two years.

Forest disturbance and recovery: A general review in the context of spaceborne remote sensing of impacts on aboveground biomass and canopy structure [PDF]

open access: yes, 2009
Abrupt forest disturbances generating gaps \u3e0.001 km2 impact roughly 0.4–0.7 million km2a−1. Fire, windstorms, logging, and shifting cultivation are dominant disturbances; minor contributors are land conversion, flooding, landslides, and avalanches ...

From Monomers to Self-Assembled Monolayers: The Evolution of Molecular Mobility with Structural Confinements [PDF]

open access: yes, 2014
The effect of structural constriction on molecular mobility is investigated by broadband dielectric spectroscopy (BDS) within three types of molecular arrangements: monomers, oligomers and self-assembled monolayers (SAMs).

Development of forest structure and leaf area in secondary forests regenerating on abandoned pastures in Central Amazonia [PDF]

open access: yes, 2005
The area of secondary forest (SF) regenerating from pastures is increasing in the Amazon basin; however, the return of forest and canopy structure following abandonment is not well understood. This study examined the development of leaf area index (LAI),

Comparison of forest attributes derived from two terrestrial lidar systems. [PDF]

open access: yes, 2013
Terrestrial lidar (TLS) is an emerging technology for deriving forest attributes, including conventional inventory and canopy characterizations. However, little is known about the influence of scanner specifications on derived forest parameters.

Composition and Host-Use Patterns of a Scarab Beetle (Coleoptera: Scarabaeidae) Community Inhabiting the Canopy of a Lowland Tropical Rainforest in Southern Venezuela [PDF]

open access: yes, 2019
The adult scarab beetle fauna of the canopy in a lowland tropical rainforest in southern Venezuela was observed and collected by means of a 42 m-tall tower crane for a complete year.

Sexual dimorphism in bite performance drives morphological variation in chameleons [PDF]

open access: yes, 2014
Phenotypic performance in different environments is central to understanding the evolutionary and ecological processes that drive adaptive divergence and, ultimately, speciation.

Effects of vegetation canopy structure on remotely sensed canopy temperatures [PDF]

open access: yesRemote Sensing of Environment, 1980
The effects of vegetation canopy structure on thermal infrared sensor response must be understood before vegetation surface temperatures of canopies with low percent ground cover can be accurately inferred. The response of a sensor is a function of vegetation geometric structure, the vertical surface temperature distribution of the canopy components ...
