Chrysanthemum White Rust

Chrysanthemum white rust is a disease caused by the fungal pathogen Puccinia horiana, a biotrophic rust fungus in the family Pucciniaceae. It is one of the most serious diseases affecting cultivated chrysanthemums globally and is classified as a quarantine pathogen in many countries. The disease was first described in Japan in the early twentieth century and has since spread to major chrysanthemum-producing regions worldwide through the international movement of infected plant material. Symptoms include pale green to yellow spots on the upper leaf surface corresponding to circular to angular white to pale pink pustules on the underside of the leaf, which produce masses of waxy, white teliospores. Unlike many rust fungi, Puccinia horiana has a simplified life cycle that does not require an alternate host, completing its development entirely on chrysanthemum. The fungus spreads readily via windborne spores, water splash, and contaminated cutting tools. Under cool, humid conditions with high relative humidity, infection can progress rapidly, causing extensive leaf damage and defoliation in severely affected plants. Strict phytosanitary measures including inspection of imported planting material, sanitation of growing facilities, and fungicide application are employed to manage the disease in commercial chrysanthemum production.

Pingüino emperador

El pingüino más grande del mundo, el pingüino emperor puede medir hasta 1,2 metros de altura y pesar 45 kg, habitando el continente antártico en algunas de las condiciones más extremas de la Tierra. Se reproduce en la oscuridad del invierno a temperaturas inferiores a -60°C, con los machos incubando un único huevo sobre sus patas bajo una bolsa de cría durante 65 días mientras las hembras están en el mar. Su comportamiento de apiñarse —haciendo circular a los individuos a través del cálido centro de grupos de miles de ejemplares— es una obra maestra de la supervivencia cooperativa.
