Turning over a new leaf, Colombian ranchers plant trees
In Colombia's southern Guaviare department, on the doorstep of the Amazon, cattle ranchers are engaged in a practice that belies their jungle-wrecking reputation. They plant trees......»»
Under the canopy: Researchers study beech leaf disease in Pennsylvania forests
In the woods of the northeastern U.S., a strange disease is creeping through the canopies. Spreading quickly, it causes leaves and branches to wither and, in many cases, the tree to eventually die......»»
Study reveals how leaf-cutting ants gauge leaf portion size
They might not be able to leap tall buildings with a single bound, but leaf-cutting ants are insect superheroes, capable of carrying leaf pieces up to six times their body mass to cultivate fungus in their borrows. But how do the charismatic creature.....»»
Blood-red crickets invade Nevada town, residents fight back with brooms, leaf blowers, snow plows
Dana Dolan was driving through her small Nevada hometown when she thought she had come upon a gory crash. The ground surrounding Elko's stretch of Interstate 80 looked as if it had been covered in blood. As the red color shifted and moved, she realiz.....»»
Researchers develop new tool to identify nematode pest in beech leaf disease
Beech leaf disease (BLD) is an emerging threat to North American forest ecosystems. It was first discovered in northeastern Ohio in 2012, and has already spread to 12 additional U.S. states and Canadian provinces. At first the cause of the disease wa.....»»
Study tracks how adaptations to living in cold climate promoted social evolution in Asian colobine primates
Asian colobines, also known as leaf-eating monkeys, have been on the planet for about 10 million years. Their ancestors crossed land bridges, dispersed across continents, survived the expansion and contraction of ice sheets and learned to live in tro.....»»
An AI-powered solution for accurately diagnosing tomato leaf diseases
Plant diseases have posed a major threat to farmers since the early days of agriculture. Today, despite our improved understanding of the causes and treatment of these diseases, they continue to cause significant economic losses. Although detecting p.....»»
Snowballing effects of beech leaf disease hurt helpful root fungi
The American beech, Fagus grandifolia, is a North American staple and the dominant species in many northeastern forests. In 2012, a new disease was first spotted, infecting trees in northeastern Ohio. The worst afflicted had dark banding on their lea.....»»
A high-throughput AI method for leaf counting
In cereal crops, the number of new leaves each plant produces is used to study the periodic events that constitute the biological life cycle of the crop. The conventional method of determining leaf numbers involves manual counting, which is slow, lab.....»»
Mysteries of the poisonous amphibians

Nissan sweetens Leaf lease after it loses EV tax credit
Nissan just cut the Leaf's monthly lease payment to $309 from $329 for 36 months......»»
In Florida study, nonnative leaf-litter ants are replacing native ants
A new look at decades of data from museum collections and surveys of leaf-litter ants in Florida reveals a steady decline in native ants and simultaneous increase in nonnative ants—even in protected natural areas of the state, researchers report......»»
Pulvinar slits in the cell wall of legume motor cells facilitate control of leaf movement
Plant movement has long fascinated many researchers. Legumes are a group of plants famous for exhibiting various leaf movements, including "nyctinastic movement," in which the leaves open in the day and close at night. Similar plant movements include.....»»
Scientists use satellites to track Earth "greening" amid climate change
North Carolina State University researchers have used satellite imagery and field sensors to estimate worldwide changes in plant leaf growth due to global warming. The researchers found that changes in "greening," or the amount of leaves plants are a.....»»
Licorice leaf extract is a promising plant protectant for conventional and organic agriculture
Pesticides have proven effective in protecting crop yield against plant pathogens, but the environmental detriment to nontarget organisms has prompted a tug-of-war between organic and conventional agriculture practices. This poses the question: How c.....»»
Forest wildflowers and their overstory trees are changing with climate, but not always keeping pace
For spring ephemerals, timing is everything. These special wildflowers grow in temperate forests around the world, early in spring before the trees leaf out. Come out too early and it's still winter, too late and it's too shady under the forest canop.....»»
How tree species link fungal partners across a large-scale forest ecosystem
In a study published in Science China Life Sciences, a team surveyed hyper-diverse fungal communities in approximately 500 paired leaf and soil samples, which were associated with 55 tree species that are located over 2,000-km span of mountain forest.....»»
Nissan wants the 2023 Ariya to be its comeback EV, but the bar has been raised
Nissan pioneered EVs with the Leaf, but with the 2023 Ariya, it's playing catch-up......»»
Microbial enzymes are the key to pectin digestion in leaf beetles
A research team at the Max Planck Institute for Chemical Ecology in Jena, Germany, shows in a new study how leaf beetles could successfully use new and previously indigestible food sources in the course of evolution. The insects acquired enzymes from.....»»
Extreme salt stress triggers leaf movement
Plant leaves can cope with much higher salt concentrations than roots. The underlying mechanism may help to develop more salt-tolerant crops......»»
