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

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

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

More trees in urban boreal forests are getting killed by climate change

,
Trees are increasingly falling victim to certain phenomena related to global warming such as drought, heat, fire and increased pests, a Finnish research has found. The figures from Helsinki's “Central Park”
PFAS are found in many products such as firefighting foams, paints, pesticides, coatings, and food packaging.

Cleaning up Europe from PFAS would cost 2 trillion over 20 years

,
The estimate is included in an investigation coordinated by the French newspaper Le Monde into the spread of PFAS in the Continent. Producers' lobby under attack
In tropical forests, says a study, the addition of nutrients would increase shoot biomass by 26% and growth rate by 14%.

Accumulation of nutrients threatens tropical forests

,
According to a study, the inflow of nutrients would eventually provide a competitive advantage to some tree species resulting in a loss of biodiversity

A Tea Bag Tells the Story of Carbon Sequestration in Wetlands

,
An unusual experiment sheds light on the impact of climate change on carbon capture in the Earth’s wetlands. In freshwater areas and tidal marshes lies the greatest sequestration potential

Soil microbes help plants to attract bees

,
According to a UC Berkeley study, mycorrhizal fungi impact flower characteristics and, consequently, the number and duration of visits by bees
Soil hosts a huge number of microbes capable of producing effective antibiotics that have yet to be discovered. Photo: USDA Public Domain Mark 1.0 Universal PDM 1.0 DeedUSDA Public Domain Mark 1.0 Universal PDM 1.0 Deed

Soil is a surprising reservoir of new antibiotics

,
Soil, a Dutch study recalls, harbors a huge number of microbes capable of producing effective and as yet unknown antibiotics. Genetic investigation makes it possible to identify them

A vitamin can decode interactions between soil microbes

,
Corrinoids, a category of nutrients to which vitamin B12 belongs, influence the functionality of soil microbiomes, two UC Berkeley studies have found
