Ecoacoustics: how soil sounds measure biodiversity

,
Australian research has highlighted the correlation between the complexity of noise produced by invertebrate communities and the level of soil biodiversity

Bacteria help predict soil acidity in grasslands

,
A new Chinese model based on bacterial analysis allows to estimate changes in grasslands. By 2100, soil acidity will decrease especially in North-East Asia, Africa and Oceania

Mozambique’s forests store more carbon than expected

,
A new study revises estimates for miombo forests upwards. Carbon from these ecosystems in Mozambique could be 2.2 times higher than previously assumed

Amazon, land protection initiatives have reduced deforestation by 83%

,
In the first decade of the century, the Amazon experienced a sharp decline in deforestation, explains an international study. But the economic benefits for the indigenous people have been limited. This is why new initiatives are needed

Forests still offset half of global fossil emissions

,
The world's forests, an American study notes, absorb between 3.5 and 4 billion tonnes of carbon each year. Equivalent to "nearly half of the carbon dioxide emissions from burning fossil fuels between 1990 and 2019."
Globally, scientists explained, wetlands are rich in biodiversity and provide various services including water supply for agricultural use and carbon storage.

Here is how the climate will affect the wetlands in North America

,
Wetlands, a study from the US explains, will experience substantial drying during the summer. Impacting habitat and biodiversity from Florida to Mississippi to southeastern Canada

Mixed forests are less vulnerable to soil acidification

,
The Chinese study: in larch and broad-leaf forests, nitrogen deposition has no significant impact on soil chemistry. Therefore, in the fight against acidification, the creation of mixed forests could be effective

The impact of wildfires on understorey and biodiversity rises in Australia

,
In areas affected by wildfires, which are increasingly severe and frequent in Australia as in the rest of the planet, there is a decrease in plant diversity

Plant genetics influences the presence of beneficial microbes in the soil

,
A study from the University of Colorado shows a correlation between a number of genetic traits in sunflowers and a set of microbes capable of fighting plant diseases

A step forward in the fight of bees against mites

,
Canadian study provides new details on the interaction between bees in their post larval stage and the Varroa destructor, a mite capable of destroying up to 40 percent of pollinator colonies each year
