Consumer perception and communication on welfare in organic laying hen farming [PDF]
, 2012 A major reason for increased societal popularity of organic production systems is the growing general discontent with intensive farming practices. However, urbanization leads to limited knowledge of farming and farm animal welfare.

Non‐native species affect the long‐term dynamics of native stream fish assemblages
Oikos, EarlyView.Characterizing the temporal changes of biotic communities and disentangling the importance of their driving mechanisms are central themes in ecology and environmental management. Non‐native species have multiple adverse impacts on native communities and species.

Ammonia Emissions of Laying-Hen Manure as Affected by Accumulation Time
The Journal of Poultry Science, 2011 A study was conducted to investigate how ammonia (NH3) emission of laying hen manure is affected by manure accumulation time (MAT). Three trials were conducted.

Effect of Heat Stress on Laying and Non-Laying Hens
Poultry Science, 1971 Abstract INTRODUCTION A REVIEW of the literature indicates that comparisons between laying and non-laying hens under heat stress conditions are very limited. Huston et al. (1957) indicated that at high environmental temperature 32.2°C. (90°F.), nonlayers had 0.4°C. (0.7°F.) higher body temperature than layers, which was highly significant.

Interactions of rare earth elements with living organisms and emerging biotechnical applications
PLANTS, PEOPLE, PLANET, EarlyView.Rare earth elements (REEs) are critical resources required to achieve net‐zero carbon emission targets and energy security. However, rising demand for REEs coupled with significant extraction and processing challenges and geopolitical risks restricts access to REE resources.

Effects of Laying Hen Manure Application Rate on Water Quality [PDF]
, 2002 Excessive use of animal manure on agricultural lands can impact the quality of surface and groundwater resources. A three–year study (1998–2000) was conducted on nine 0.4–ha plots and on six 2.1–m 2 lysimeters to investigate the effect of two nitrogen (N)

Proteins: Structure, Function, and Bioinformatics, EarlyView.ABSTRACT Protein crystallization remains a major bottleneck in X‐ray crystallography due to difficulties in achieving favorable molecular arrangements within the crystal lattice. While protein–protein interactions at molecular packing interfaces are crucial for determining crystallization conditions, methods for predicting crystal packing interfaces ...
