Monitoring biomass burning aerosol transport using CALIOP observations and reanalysis models: a Canadian wildfire event in 2019 [PDF]

Atmospheric Chemistry and Physics
In May–June 2019, smoke plumes from wildfires in Alberta, Canada, were advected all the way to Europe. To analyze the evolution of the plumes and to estimate the amount of smoke aerosols transported to Europe, retrievals from the spaceborne lidar CALIOP (

Distribution under climate change of Anemone coronaria: linking flower colour and seed dispersal

Nordic Journal of Botany, EarlyView.
Flower colour polymorphism is driven by divergent selection regimes on the colour morphs across time and space. Anemone coronaria, a colour‐polymorphic geophyte with red, purple, and white flowers, displays a geographic pattern along Israel's aridity gradient: polymorphic populations are restricted to Mediterranean climates, while monomorphic‐red ...

Flowering out of sync: Climate change alters the reproductive phenology of Terminalia paniculata in the Western Ghats of India

PLANTS, PEOPLE, PLANET, EarlyView.
Understanding how climate change impacts the plant life cycle is critical for maintaining biodiversity and ecosystem services. Our findings suggest that Terminalia paniculata Roth, a common tropical deciduous tree species in the Western Ghats, is now flowering and fruiting at more scattered times than it used to in the past.
