Bamboo bear

ジャイアントパンダ（Ailuropoda melanoleuca）は中国中部の山岳竹林に生息し、体重最大125キログラムになるクマ科の動物で、食肉目に分類されながら食事の99%を竹が占める特異な食性を持つ。偽の親指（橈側種子骨）を使って竹の茎を把握し、1日14時間もの採食時間を費やす。2016年にIUCNレッドリストで絶滅危惧から危急（VU）へ改善されており、保護繁殖プログラムと自然保護区の設置が個体数回復に貢献している。

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.
