The Guardian—Bumblebee nests are overheating to fatal levels, study finds. More frequent heatwaves mean bees are unable to thermoregulate their hives – further endangering a species already in declineBumblebee nests may be overheating, killing off broods and placing one of the Earth’s critical pollinators in decline as temperatures rise, new research has found.Around the world, many species of Bombus, or bumblebee, have suffered population declines due to global heating, the research said. Bumblebee colonies are known for their ability to thermoregulate: in hot...

Phys.org—Climate change threatens mountain meadows by reducing humus content, finds study. Mountain meadows are unique ecosystems. A research team led by the Technical University of Munich (TUM) has now discovered that climate change reduces the humus content as well as the nitrogen stores in the grassland soils of the Alps and disturbs the soil structure. Organic fertilization, for example with liquid manure, can compensate this loss of soil organic matter to some extent.
