Prescribed burns may generate over 20% of fine particle pollution in southeastern US
Prescribed fires are vital for reducing wildfire risk and sustaining forest biodiversity. But they also contribute significantly to air pollution and smoke exposure, according to new research from the University of Georgia. The issue is especially pertinent to the southeastern Un

Brown leaves before fall could signal lasting heat damage, researchers warn
Due to increasing heat and drought, forests are turning brown more often before autumn, when leaf senescence normally occurs. It is often unclear whether the trees are actively shedding foliage to avoid a breakdown in water transport or whether browning leaves are a consequence o

A benchmark for how different disturbances influence the loss and recovery of carbon and C
Tropical moist forests account for 70% of global living biomass. Deforestation and degradation—that is, the partial damage to tree stands—as well as the subsequent regeneration of forests therefore play a pivotal role in the global carbon cycle. While the effects of large-scale t

Hidden fungal networks deliver carbon to green plants, experiment confirms
Hidden fungal networks deliver carbon to green plants, experiment confirms
Beneath forests, grasslands and wetlands lies a hidden underground network of fungi known as mycorrhizal networks, sometimes nicknamed the "wood-wide web." These fungi live in partnership with plant roots, helping plants absorb nutrients from the soil in exchange for carbon compo

Storms impact the architecture of webs and the survival of spiders
In the dense forests of the Ecuadorian Andes, the survival of a spider relies not only on its ability to prey on insects but also on its capacity to resist a threat coming from the skies. A new study revealed that the heavy rainfall that hits the region acts as an "ecological fil

Study provides further evidence that aspen patches can mitigate wildfires
Study provides further evidence that aspen patches can mitigate wildfires
Researchers at McGill University have confirmed that aspen play a key role in forest fire prevention and mitigation across Canada. Planting these trees near communities can reduce both the likelihood and severity of fires and limit how far they spread, the researchers said.

How tall and short trees can coexist in old growth forests
Forests are shaped by light competition. The trees that grow the tallest have access to the most sunlight, blocking the rays and rendering the shaded space around them inhospitable to shorter trees below. In this stem exclusion phase of forest succession, the shorter trees often

Trees keep absorbing carbon long after they stop growing
Trees keep absorbing carbon long after they stop growing
Oak trees keep absorbing carbon dioxide long after their annual growth has ended, revealing that photosynthesis and wood production are not as closely linked as scientists once believed. The finding could reshape forecasts of how much carbon forests will be able to store in a war

'It felt a bit James Bond': The mission to reintroduce a lost insect
Species Recovery Trust hopes to reintroduce the New Forest cicadas not seen in UK since the 1990s. O recorte ajuda a contextualizar a pauta dentro de Agro.

Experimental bathtub: the remote lake island trying wave power to boost energy security
Researchers on Beaver Island, in Lake Michigan, are trying to find a more reliable form of power using local resourcesBeaver Island sits in the middle of the northernmost end of Lake Michigan, about 70 miles from the maritime border with Canada. The forested island, just a little

Tropical forests can switch from carbon sinks to carbon sources during El Niño
Tropical forests draw down and store large quantities of CO₂ from the atmosphere. The Amazon rainforest in South America, for example, stores approximately 123 billion tons of carbon—more than is stored in any other terrestrial ecosystem in the world. But these forests are facing

Why natural forests survive heat waves better than planted forests
When a record-breaking drought and heat wave swept across China's Yangtze River Basin in 2022, forests across the region faced an extreme test. The event provided a rare opportunity for researchers to test how different forests respond when rising temperatures and water shortages
