Researchers found that the solitary rodents build structures weighing up to 48 kilograms, with tunnels, chambers and basking platforms that help them cope with the harsh Karoo climate.

Genomic surveillance shows how resistant Vibrio cholerae can persist between outbreaks, with floods and droughts helping them survive and spread.

Across rural Africa, invasive species are shrinking grazing and farming land, and damaging livelihoods.

The newly described species evolved in isolation on ancient forested peaks, but extensive habitat loss may already be putting them at risk.

Des chercheurs ont découvert que ces rongeurs solitaires construisent des structures pouvant peser jusqu’à 48 kilogrammes, dotées de tunnels, de chambres et de plates-formes pour se prélasser au soleil, qui les aident à faire face au climat rigoureux du Karoo.

La surveillance génomique montre comment les souches résistantes de Vibrio cholerae peuvent persister entre deux épidémies, les inondations et les sécheresses favorisant leur survie et leur propagation.

Global finance is flowing into mass planting of the indigenous succulent, but ecologists disagree over how, and how soon, to judge whether the wider ecosystem will recover.

Des fonds internationaux affluent vers la plantation à grande échelle de cette plante succulente indigène, mais les écologistes ne s’accordent pas sur la manière et le délai nécessaires pour déterminer si l’écosystème dans son ensemble se rétablira.
