Living mulch functions like mulch on any farm or garden except -- it's alive. No, it's not out of the latest horror movie; living mulch is a system farmers can use to benefit both profits and the soil. While the system has been around for a while, scientists at the University of Georgia are making it more efficient and sustainable.
A study published recently in Environmental Toxicology and Chemistry found that Blanchard's cricket frogs are highly sensitive to atrazine. When exposed, there were up to 55 percent fewer males than females compared with the control group, indicating that atrazine can affect the sex ratio. However, cricket frog populations do persist in areas with widespread atrazine application, despite reports of range contractions for enigmatic reasons.
A new study published in the Journal of Wildlife Management looks at whether management of livestock grazing may help protect sagebrush and birds that depend on it.
Researchers at Umeå University and Wageningen University have discovered how plants can defend themselves against aphids. They recorded aphid behavior on video, and identified a plant protein that keeps aphids from feeding. The results have been published in the journal the Plant Cell.
Natural essential oils extracted from the peel of a citrus fruit could be an effective new eco-friendly alternative in mosquitoes control programs, reports a new study published today in Natural Product Research.
Pest resistance to genetically engineered crops Bt crops is evolving faster now than before, UA researchers show in the most comprehensive study to date. But as expected from evolutionary theory, resistance can be delayed if farmers comply with recommendations to make use of abundant refuges.
Two papers published in Irrigation and Drainage may help improve estimates of water requirements for crops, which will save water and minimize losses, allowing more land to be irrigated and subsequently more food to be produced.
Understanding how parasitoids and hosts interact, and how their interactions change with human influence, is critically important to understanding ecosystems. New research by an international team of researchers finds mathematical models can predict complex insect behavioural changes using a simple description of insect preferences.
Increased agricultural production has likely led to loss, fragmentation, and degradation of flower-rich habitats for pollinators. To counteract these negative effects of modern agricultural practices, efforts to maintain and restore diverse plants in agricultural landscapes -- called agri-environmental schemes (AES) -- have been implemented in numerous European countries.
John Innes Centre researchers used a study of the plant-growth promoting bacterium Pseudomonas fluorescens to develop an advanced analysis method which, they hope, will increase our capacity to understand plant and human diseases.
