Carbon dioxide and methane exchange of a patterned subarctic fen during two contrasting growing seasons [PDF]

open access: yesBiogeosciences, 2021
The patterned microtopography of subarctic mires generates a variety of environmental conditions, and carbon dioxide (CO2) and methane (CH4) dynamics vary spatially among different plant community types (PCTs). We studied the CO2 and CH4 exchange between

Microbial diversity and proxy species for human impact in Italian karst caves

open access: yesScientific Reports, 2023
To date, the highly adapted cave microbial communities are challenged by the expanding anthropization of these subterranean habitats. Although recent advances in characterizing show-caves microbiome composition and functionality, the anthropic effect on ...

Evapotranspiration of Irrigated Crops under Warming and Elevated Atmospheric CO2: What Is the Direction of Change?

open access: yesAtmosphere, 2022
Future changes in crop evapotranspiration (ETc) are of interest to water management stakeholders. However, long-term projections are complex and merit further investigation due to uncertainties in climate data, differential responses of crops to climate ...

Effect of the Solar Zenith Angles at Different Latitudes on Estimated Crop Vegetation Indices

open access: yesDrones, 2021
Normalization of anisotropic solar reflectance is an essential factor that needs to be considered for field-based phenotyping applications to ensure reliability, consistency, and interpretability of time-series multispectral data acquired using an ...

Impact of environmental inputs on reverse-engineering approach to network structures [PDF]

open access: yes, 2009
Background: Uncovering complex network structures from a biological system is one of the main topic in system biology. The network structures can be inferred by the dynamical Bayesian network or Granger causality, but neither techniques have seriously ...

How input fluctuations reshape the dynamics of a biological switching system [PDF]

open access: yes, 2012
An important task in quantitative biology is to understand the role of stochasticity in biochemical regulation. Here, as an extension of our recent work [Phys. Rev. Lett. 107, 148101 (2011)], we study how input fluctuations affect the stochastic dynamics

High Resolution Multispectral and Thermal Remote Sensing-Based Water Stress Assessment in Subsurface Irrigated Grapevines

open access: yesRemote Sensing, 2017
Precision irrigation management is based on the accuracy and feasibility of sensor data assessing the plant water status. Multispectral and thermal infrared images acquired from an unmanned aerial vehicle (UAV) were analyzed to evaluate the applicability
