Droughts can be good for trees; certain trees, that is......»»
Mars analog stations investigate lichen biodiversity during simulated missions
Once you know where to look for them, lichens are everywhere. These composite organisms—fungal and photosynthetic partners joined into a greater whole—can survive on a vast array of surfaces, from rocks and trees to bare ground and buildings. The.....»»
Up in smoke: DIY tech to combat wildfires
As wildfires become a more frequent and dangerous part of life, especially in the Pacific Northwest, finding solutions that everyone can use is more important than ever. By June 2024, the Pacific Northwest had already seen more trees burn than in all.....»»
Climate change can alter methane emission and uptake in the Amazon
Extreme temperatures and humidity levels (excessive rain or drought) projected for the Amazon in the context of climate change may increase the volume of methane-producing microorganisms in flooded areas and reduce potential uptake of this greenhouse.....»»
Fall is here: Why do some trees lose their leaves while others stay green?
The autumn has arrived and northeastern North America's forests will soon grace us with a breathtaking palette of reds, yellows and golds. These vivid colors will then fade, giving way to bare branches, as the fallen leaves blanket the forest floor,.....»»
Researchers find dragonfly species with darker wings have evolved to withstand heat and attract partners
Temperature determines where species can live and if they are threatened by a warming climate. So, for a long time, biologists studied how heat tolerance affects survival. Yet, less is known about how thermal traits influence reproduction, which is d.....»»
“Sticky” steering sparks huge recall for Honda, 1.7M cars affected
The problem affects a number of different Hondas built since 2021. Honda is recalling almost 1.7 million vehicles due to a steering defect. An improperly made part can cause cert.....»»
One dead as storm Kirk tears through Spain, Portugal, France
The remnants of Hurricane Kirk swept into western Europe Wednesday, tearing up trees in Portugal and Spain before dumping heavy rains on France that left at least one dead......»»
Auto industry appears divided on lidar"s value in automated driving systems
Lidar sensors were once considered essential equipment for self-driving vehicles and, to a lesser extent, driver-assistance functions. Their value today depends on whom you ask......»»
Greening of Antarctica shows how climate change affects the frozen continent
Plant growth is accelerating on the Antarctic Peninsula and nearby islands. When satellites first started peering down on the craggy, glaciated Antarctic Peninsula about 40 years.....»»
Greening of Antartica shows how climate change affects the frozen continent
Plant growth is accelerating on the Antarctic Peninsula and nearby islands. When satellites first started peering down on the craggy, glaciated Antarctic Peninsula about 40 years.....»»
Trees" own beneficial microbiome could lead to discovery of new treatments to fight citrus greening disease
Citrus trees showing natural tolerance to citrus greening disease host bacteria that produce novel antimicrobials that can be used to fight off the disease, our recent study shows. We found the trees at an organic farm in Clermont, Florida......»»
Field notes: Life in the Eldorado National Forest after wildfire strikes
Charred trees punctuated the Eldorado National Forest like blackened skeletons of their former selves, victims of the Mosquito Fire. Two years earlier, in 2022, the Mosquito Fire started in Tahoe National Forest, moved north to the Eldorado and torch.....»»
Stellantis hybrid sales in Europe constrained by transmission supply, Carlos Tavares says
The ramp-up of a dual-clutch transmission at factories in Italy and France is holding back sales of models with Stellantis' new 48-volt hybrid powetrain, which can cut emissions by up to 25 percent, CEO Carlos Tavares said......»»
Study suggests statistical "noise" affects perceived evolutionary rates
For decades, researchers have observed that rates of evolution seem to accelerate over short time periods—say five million years versus fifty million years. This broad pattern has suggested that "younger" groups of organisms, in evolutionary terms,.....»»
New research uncovers how climate and soil shape tree and shrub wood density across ecosystems
An article published in Advances in Atmospheric Sciences has provided new insights into how wood density in trees and shrubs adapts to different climate and soil conditions. Led by Dr. Song Xiang from the Institute of Atmospheric Physics at the Chine.....»»
Report: Global drought threatens food supplies and energy production
In July 2024, global temperatures reached unprecedented levels, breaking historical records with an average of 17.16°C. This extreme heat has led soil water to evaporate, leaving the vegetation and biodiversity more fragile and under stress in many.....»»
The biodiversity jukebox: How sound can boost beneficial soil microbes to heal nature
In a race against time, scientists are exploring new ways to restore natural systems. Alongside traditional methods such as planting trees, reducing pollution and reintroducing native species, a surprising new tool is emerging: sound. Ecologists can.....»»
How climate change is undermining Indigenous knowledge and livelihoods in Central America
Driven by extreme heat and drought, some of the worst wildfires in living memory raged across Mexico and Central America through April and May 2024......»»
Smoke from megafires puts orchard trees at risk: Effects last months, reducing nut yields
Long-term smoke exposure from massive wildfires lowers the energy reserves of orchard trees and can cut their nut production by half, researchers at the University of California, Davis, found. The smoke can affect trees for months after a megafire, d.....»»
New study maps Congo"s bai ecosystems in unprecedented detail
"Tropical rainforest" might conjure images of close-packed trees, dense humidity, and the din of animal calls. But rainforests host landscapes beyond that archetypal one, including vast, treeless clearings that seemingly appear out of nowhere......»»
