A silent biodiversity loss threatens the Planet

,
An international study introduces the concept of dark biodiversity, which helps to understand the completeness of an ecosystem in relation to its natural potential. The greater the human pressure, the lower the ability of the system to proliferate
Turisti in coda per visitare il villaggio di Aceredo, in Spagna, riemerso dalle acque durante la siccità del 2022. Gli eventi estremi, come le ondate di calore, possono trasformare gli ecosistemi in fonti di emissioni nette di carbonio.

Drought and extreme heat reduce carbon sequestration capacity in plants

,
Plant respiration and decomposition of organic matter increase carbon emissions offsetting additional sequestration associated with extended growing season, a study by the Autonomous University of Barcelona finds
Around the Chernobyl “Exclusion zone” (photo) extends the so-called “Compulsory relocation zone,” which has never been fully abandoned. Thousands of people live in the area but no official investment or land use is allowed.

Low-contamination soils near Chernobyl could now be cultivated, study claims

,
Research involving British and Ukrainian researchers hypothesizes the recovery of large areas of the Chernobyl area where cultivation has been officially banned for nearly 40 years

Citizen science provides valuable help to soil monitoring

,
Supported by Prepsoil's database, new research highlights the benefits of citizen science. The approach proves effective but common standards and validation technologies are needed
In the Caatinga area of Brazil, three years after the elimination of grazing, there are no significant improvements for the soil. Photo: Otávio Nogueira Attribution 2.0 Generic CC BY 2.0 DeedPhoto: Otávio Nogueira Attribution 2.0 Generic CC BY 2.0 Deed

Overgrazing halt not enough to restore soil in Brazil

,
The study in the Caatinga region in Brazil: stopping grazing is not enough to restore soil health. Additional regenerative practices must be adopted to achieve results

US agriculture pays the price of atmosphere “thirst”

,
An American study introduces the concept of “thirst waves.” In the US they have been on the rise for at least four decades. The phenomenon occurs when evaporative demand is high and plants therefore need more water
Forest integrity is increasingly threatened by natural events exacerbated by climate change in addition to anthropogenic pressures.

Crisis of forests may double climate mitigation costs

,
This is the hypothesis of researchers at the Potsdam Institute. Current models overestimate the mitigation potential of forests. In this scenario, a delay in response could make the climate goals unattainable
Rocky outcrops are common in mountain ecosystems and exert a significant impact on ecosystem functions. Photo: Copyright Chris Gunns and licensed for reuse under this Creative Commons Licence Attribution-ShareAlike 2.0 Generic CC BY-SA 2.0 Deed

How rock outcrops impact soil in the mountains

,
A Chinese study describes and measures the effect of outcrops on the soil. These create specific localized “hotspots” where soil functions are enhanced. Rock size amplifies effect
Among microbes in urban spaces, there is increasing similarity among bacteria, while fungi are more resistant to homogenization.

Soil microbes react in different ways to urbanization

,
An international study describes the impact on various microbial communities. Although with different responses, bacteria and fungi maintain their basic functions thus ensuring ecosystem services
In Antanarivo, Madagascar, soil extraction has been accompanied by the spread of terrace farming and resilient crops according to a study. Photo: Visiting Madagascar Attribution-ShareAlike 2.0 Generic CC BY-SA 2.0 DeedVisiting Madagascar Attribution-ShareAlike 2.0 Generic CC BY-SA 2.0 Deed

From soil extraction new opportunities for agriculture

,
The production of building materials through soil negatively impacts the landscape but also opens up new possibilities for the development of climate and flood resilient agriculture. A lesson from Madagascar
