As humans break up forests and fragment habitats, it’s not just species that are lost but also the way ecosystems work, a new study finds. A paper recently published in Ecology Letters compares how mammals are connected through food webs – meaning who eats who or what – in 127 protected areas across Africa. It’s the first study to compare food web similarity at a continental scale.

New evidence shows melt ponds in the northern parts of the Arctic may be biological sources of ice-nucleating particles, a key ingredient for cloud formation that has been largely overlooked.

As climate change intensifies and global food security faces pressures, accurate monitoring of crop phenology—especially sowing dates—has become critical for optimizing agricultural management and improving climate resilience. Winter wheat, a staple crop supporting nearly 40% of the global population, relies heavily on timely sowing to maximize yield potential. However, traditional monitoring methods such as field surveys are labor-intensive and unscalable, while existing remote sensing approaches suffer from soil background interference and static environmental data limitations.
