New study finds that the nutritional value of prey within a single species can widely vary, offering key insights for food web dynamics and ecosystem change The hunt is on and a predator finally zeroes in on its prey. The animal consumes the nutritious meal and moves on to forage for its next target. But how much prey does a predator need to consume? Following a period of massive starvation among animals living along the California coast, University of California…
Left-sided displacement of the abomasum (LDA) is an economically important disease in Holstein dairy cattle populations all over the world. The bovine abomasum…
If farmers don't move their corn north, the more frequent heat waves could lead to bigger swings in corn prices – “price volatility” – which cause spikes in…
For 300 million years, they were the ultimate survivors. They successfully negotiated three mass extinctions, only to die out eventually at the end of the…
With different accompanying measures, such as the conservation of near-nature areas, however, these effects could be partly reduced, as scientists of the…
Azinphos-methyl (AZM) has been the most used insecticide in apple production in the United States since the late 1960s, primarily as a control for the codling…
Consequently, it is important to detect the potential impact of climate changes on the Himalayan glaciers at an early stage. Together with international…
The team examined six years-worth of atmospheric gas measurements of carbon dioxide (CO2) and other gases, taken by aircraft every two weeks. Their method…
The research team looked at atmospheric gas measurements taken every two weeks from aircraft over a six-year period over the northeast United States to collect…
This competition has sparked concern for the more fundamental issue of allocating limited farmland resources, which has far-reaching implications for food…
The study shows that when the cod population in the central Baltic increases, it spreads into larger areas and spills over into adjacent marginal systems where…
The six papers appeared in the April issue of the journal BioScience. The papers were tied to data gathered at sites in North America, Puerto Rico, the island…
In a recent paper,* the team led by NIST chemist Bryant C. Nelson showed that under laboratory conditions, cupric oxide nanoparticles have the capacity to…
“We’ve been working to create trees that grow faster and produce more wood, and what this research shows is that at the same time we’re enhancing environmental…
An increasing number of crops commercially grown today are genetically modified (GM) to resist insect pests and/or tolerate herbicides. Although Bt corn is one…
