Rubisco activase best clue for better photosynthesis in fluctuating light
Scientists and plant breeders who are aiming to improve food production by improving photosynthesis in crop plants, would make a good choice if they chose to change the composition and concentration of the protein Rubisco activase. In conditions where light intensity changes often and strongly, Rubisco activase is an important limiting factor in boosting the photosynthesis process when light ...

Common Pesticide Reduces Food Value of Algae
SILVER SPRING, Maryland (ENS) - Researchers with the NOAA National Centers for Coastal Ocean Science have identified negative effects of the commonly used herbicide atrazine on phytoplankton, the free-floating algae that form the base of the food chain for aquatic animals. Published in the current issue of the journal 'Pesticide-Biochemistry and Physiology,' the study indicates protein levels ...

Sustainability at Iggesund: A key factor in all decisions
Many small steps add up to large ones. That’s a simple way to sum up Iggesund Paperboard’s environmental work. It is easy to give examples of Iggesund’s multi-million euro investments and their importance. But the company also makes many smaller investment decisions which have important environmental aspects. One of these is the wooden bridge that links the mill at Iggesund with ...

Increasing aridity will disrupt soil nutrient cycles in global drylands
The drying of soils under global warming could disrupt the balance of nutrients in large areas of the Earth’s land surface, according to new research. The study focused on ‘drylands’ – arid areas with low levels of rainfall – which support over 38% of the world’s population. Such nutrient imbalances could diminish the provision of ecosystem services, such as ...

Forest Soil Carbon Flux Measurement and Applications
Measuring forest soil carbon flux gives an insight into the health of forest ecosystems and provides feedback on the effects of global warming. This article outlines how soil CO2 efflux is determined and the applications of soil carbon flux research. The Earth’s carbon cycle maintains a steady balance of carbon in the atmosphere that supports plant and animal life. In recent years, ...

Lighting strategies for LEDs in greenhouse horticulture
The use of assimilation lighting in greenhouse horticulture has increased by 10% per year during the past decade, leading to a considerable increase in electricity consumption. LED lighting systems have a variety of advantages, ranging from their small size, high energy conversion efficiency to the option to emit specific wavelengths. In the EU project HI-LED, Wageningen UR Greenhouse ...

Proper Irrigation of the Garden Using Intelligent Measurement Technology
In addition to the factors of light, temperature and nutrient availability, water is one of the most important prerequisites for healthy plant growth. If a plant lacks water, this not only inhibits growth, but in the worst case even leads to death of the plant. Since dry periods in summer are not uncommon, irrigation is of particular importance in practice. Water: The basic criterion for a ...

Australia Invites Nations to Monitor Forests for Climate`s Sake
SYDNEY, Australia, July 23, 2007 (ENS) - Australia will establish a new global system to monitor changes in forest cover and forest carbon levels as part of its A$200 million Global Initiative on Forests and Climate, government officials announced today. Minister for Foreign Affairs Alexander Downer, and Environment and Water Resources Minister Malcolm Turnbull introduced the initiative at a ...
