A paper published in the CABI Reviews journal has found that climate change is the most prominent threat to pollinators – such as bumblebees, wasps, and butterflies – who are essential for biodiversity conservation, crop yields and food security.

A biological mechanism familiar to people who fast helps plant roots grow strong. 

The discovery of how a critical enzyme “hidden in nature’s blueprint” works by scientists from The Australian National University (ANU) and the University of Newcastle (UoN) could help engineer climate resilient crops capable of sucking far more carbon dioxide from the atmosphere in a much more efficient way.

Like forests, grassland provides numerous ecological, economic and social benefits.

A nonnative tree-killing insect is invading northern Utah, attacking subalpine fir and potentially triggering yet another die-off of the region’s long-stressed conifer forests.

Farmers in a time crunch have a new, speedier option for analyzing the texture and organic matter content of the soil on their fields.

Gerson Drescher, assistant professor of soil fertility for the Arkansas Agricultural Experiment Station, led a study to create prediction models for these key soil health indicators based on standard tests already being used to analyze soil samples.

“We want to provide people with the maximal amount of information that they can get from samples they are already submitting without the additional cost and time of analysis,” Drescher said.

The newly developed prediction model can help add information about the soil’s properties, which can guide fertilization, irrigation, and herbicide decisions, Drescher added. Standard soil testing evaluates plant-available nutrient content and soil pH. However, these properties are also affected by soil texture and organic matter in the soil, which require additional expensive and time-consuming tests.

Scientists say artificial intelligence can transform the identification and monitoring of species across the world, providing a revolutionary tool in supporting action to understand and reverse biodiversity losses.

The invasive insect emerald ash borer is killing ash trees at an unprecedented rate in the United States, and now five North American species of ash are considered critically endangered, according to the U.S. Department of Agriculture (USDA) Forest Service.

Drones monitoring fields for weeds and robots targeting and treating crop diseases may sound like science fiction but is actually happening already, at least on some experimental farms. 

On a blustery March morning, Petya Campbell stood atop a 204-foot-tall tower and looked across the waving canopy of the leafless deciduous forest at the Smithsonian Environmental Research Center in Edgewater, Maryland.
