Las diatomeas, microalgas que generan el 20 % del carbono del planeta, no solo sobreviven en la oscuridad: un estudio revela que duplican su arsenal químico defensivo tras semanas sin luz.
Las diatomeas, una caja de sorpresas químicas para sobrevivir en la oscuridad
Las diatomeas, un ejemplo de éxito de supervivencia, generan unos compuestos químicos que les sirven para protegerse de depredadores y para comunicarse entre ellas. Estudios recientes demuestran que su capacidad de producirlos se incrementa tras periodos de latencia en la oscuridad.

How perturbed does the planet need to get for ecological systems to exceed their limits to survive? It depends on the parameter we look at. Some (like sea ice extent) are still at risk even under low-emissions scenarios. In high emissions - everything's red. 🧪
