The importance of phenology for the evaluation of impact of climate change on growth of boreal, temperate and Mediterranean forests ecosystems: an overview

These phenological models were coupled to the process-based forest model FORGRO to evaluate the effect of different climate change scenarios on growth and indicate that the phenology of each of the forest types significantly affects the growth response to a given climate change scenario.
Predicting the environmental impacts of chicken systems in the United Kingdom through a life cycle assessment: egg production systems.
A life cycle assessment (LCA) method was applied to quantify the environmental burdens per 1,000 kg of eggs produced in the 4 major hen-egg production systems in the United Kingdom: 1) cage, 2) barn, 3) free range, and 4) organic.

The simulated needle damage increased as a result of climatic warming, and the differences in the chilling requirement had a stronger effect on the amount of damage in the warmed climate than in the present climate.
Combining thermal and visible imagery for estimating canopy temperature and identifying plant stress.
A new method for processing and analysing thermal images was developed that allows more accurate estimation of the indices, which are consequently more closely related to stomatal conductance, and gives more accurate estimates of the temperature distribution of the shaded and sunlit parts of canopy.

The aim of this study was to apply the life cycle assessment (LCA) method, from cradle to gate, to quantify the environmental burdens per 1,000 kg of expected edible carcass weight in the 3 main…

The results suggest that estimates of the absolute magnitude of gs are somewhat subjective, depending on the skill of the experimenter at selecting evenly exposed leaves, and relative treatment differences in conductance are sensitively detected by different experimenters.
On the relationships between stomatal resistance and leaf temperatures in thermography
Artificial selection for improved energy efficiency is reaching its limits in broiler chickens
The biological potential for further improvements in efficiency and environmental impact reduction is minimal relative to past progress already made via artificial selection, and a unique analytic approach provides biologically sound guidelines for strategic planning of sustainable broiler production.
Breeding for efficiency in the broiler chicken: A review

- 7 November 2016
This review assesses the consequences of artificial selection on the following traits: digestive efficiency, body composition and utilisation of metabolisable energy for growth and metabolic activity and finds that the digestive system has been subjected to much physical change due to selection, but this has not led to any apparent change in digestion efficiency.
Evaluation of six process‐based forest growth models using eddy‐covariance measurements of CO2 and H2O fluxes at six forest sites in Europe
Reliable models are required to assess the impacts of climate change on forest ecosystems. Precise and independent data are essential to assess this accuracy. The flux measurements collected by the…
