Pollination in Australia more than halved in 50 years according to orchids

,
Thanks to their limited “flexibility,” orchids are early indicators of the crisis affecting insects. Since the 1970s, an analysis by the University of Canberra reveals, pollination in Australia has declined by 60%
At least one fifth of the 8,500 animal species linked to the soil, including fungi and invertebrates, would today be at risk of extinction. CC0 Public Domain Free for personal and commercial use.

One in five soil-dependent species is at risk of extinction

,
A new study by Conservation International and IUCN reveals that over 20% of soil-related species could disappear. And the current lack of data suggests an even more problematic picture for biodiversity

The forest at home: in Finland, soil microbes improve human health

,
A Finnish study shows how introducing forest soil into domestic environments increases the microbial diversity of indoor air, with potential protective effects on the immune system of infants growing up in enclosed spaces

2050 is the point of no return in halting the decline in biodiversity in Great Britain

,
In the worst-case scenario, a study highlights, at least 200 species are at risk of extinction while 9 out of 10 plant habitats will face lasting changes. And there is ever less time to reverse the course.
The study, conducted in the forests of Yunnan Province, demonstrated how altitude-driven environmental changes shape the genetic potential for phosphorus mineralization in the soil. At the same time, soil pH acts as a constant filter, limiting the microbial community capable of performing this vital function across different landscapes.

Elevation, pH, and calcium are key factors in the phosphorus cycle

,
A Chinese study has identified the key factors influencing the distribution of available phosphorus in tropical and subtropical forests, by modelling the genetic potential for phosphorus mineralization in soil

Beyond the Amazon: a forgotten carbon reserve in Brazil’s wetlands

,
In the Brazilian savanna, wetlands store enormous amounts of carbon, but they are threatened by climate change and agricultural expansion. Moreover, conservation policies, which focus almost exclusively on forests, tend to ignore them

Climate change is disrupting the symbiotic relationship between plants and soil fungi

,
A thirty-year experiment in the US shows how rising temperatures are transforming ecosystems internally: the abundance of fungi that are useful to plants is declining, while decomposers are increasing. As a result, soil ecological stability is being disrupted

A new index measures soil health in mangrove forests

, ,
Brazilian researchers have developed an indicator to measure the ability of mangroves to provide ecosystem services, ranging from biodiversity conservation to carbon sequestration. The greater the soil degradation, the lower the score
Peatlands used for paludiculture are home to about three times as many birds as drained grasslands, reaching levels similar to those of natural wetlands. Photo: Melissa McMasters Attribution 2.0 Generic CC BY 2.0 DeedMelissa McMasters Attribution 2.0 Generic CC BY 2.0 Deed

Adapted farming in peatlands is also good for biodiversity

, ,
Peatlands converted to paludiculture support three times as many birds as drained grasslands, with levels similar to those found in natural wetlands, according to a British study
