Climate change threatens mountain plant biodiversity in Africa

,
Rising temperatures in Africa are driving plant species to spread at higher altitudes, a German study claims. But the process is too fast, and the risk of losing their habitat is growing as a result
The shrub woolly willow is a species that is becoming increasingly common in the barren mountains of Sweden within the Arctic tundra. Photo: Anne Bjorkman, University of Gothenburg press releaseAnne Bjorkman, University of Gothenburg press release

In the Arctic tundra, boreal plants are becoming increasingly widespread due to climate change

,
A Swedish study shows the dynamics of this phenomenon. The process doesn't necessarily happen where warming is greatest but, instead, where conditions are favorable for plant growth
Favored by climate change, phenomena such as heat waves, droughts, fires, storms, and the spread of plant diseases are increasing tree mortality globally. Photo: PickPik Royalty-Free photo

Global tree mortality is getting higher. But we don’t know by how much

,
Climate change increases tree mortality rates, but figures are incomplete and a global estimate is hard to make. A group of researchers explains how to harmonize data

Freeing up soil is possible. Experts share regeneration experiences trough de-sealing

,
Soil sealing is a global problem affecting large urban centers. But new tools, explains the FAO, can now guide sustainable planning

Human activity causes carbon loss in deserts

,
Some human-induced disturbances cause significant carbon loss in the soil of hyper-arid environments, a Chinese study claims. Among the most impactful activities even some practices considered “sustainable” such as seasonal harvesting and irrigation

Soil microbes tell the story of oil contamination

,
An international study has revealed how microbes can act as markers to distinguish between recent and ancient oil pollution. This overcomes the limitations of traditional chemical analysis

Hyperspectral images reveal the health status of vegetation in Antarctica

,
An Australian study reveals the importance of aerial survey based on a more advanced technique to assess the health and density of vegetation in an area with limited spectral range such as Antarctica. The highest accuracy exceeds 99%

The trees that weren’t there: a new map reveals previously unseen plants in the tropics

, ,
New research reconsiders the presence of trees in tropical regions. Until now models excluded one in six plants. Thus ignoring the related ecological benefits
