Common wheat

<em>Triticum aestivum</em>, commonly known as common wheat or bread wheat, is an annual cereal grass in the family Poaceae and one of the most economically important crop plants on Earth. Its conservation status is listed as Not Evaluated by the IUCN, as it is a cultivated species with no wild populations requiring conservation assessment. It is grown globally across an enormous range of climatic zones, from the temperate grasslands of Europe and North America to the subtropical plains of South Asia and Australia. <em>Triticum aestivum</em> is a hexaploid species, containing six sets of chromosomes derived from hybridization events among ancestral wild grasses, which contributes to its genetic diversity and adaptability. The plant typically reaches 60–120 cm in height and produces characteristic spike-like inflorescences bearing grains enclosed in protective husks. It is the primary source of flour for bread, pasta, and a vast array of food products worldwide. As a cultivated annual, it completes its life cycle in approximately 7–8 months from sowing to harvest. Biological traits including average lifespan as a cultivated annual, precise height ranges, and mass per plant remain incompletely standardized across the enormous diversity of cultivated varieties. Ecologically, wheat cultivation has profoundly shaped agricultural landscapes, and wild relatives in the Triticum and Aegilops genera are important genetic resources for breeding disease-resistant and climate-resilient varieties for global food security.

Polar bear

地球上で最大の陸上肉食動物であるホッキョクグマは700kgを超えることがあり、カナダからロシアまでの北極海氷域全体に分布する。ワモンアザラシとヒゲアザラシを狩るために海氷に依存する高度に特化した海洋哺乳類である。広大な距離を泳ぐことができる優れた泳者でもある。脆弱種に指定されており、気候変動による急激な北極海氷の消失で個体群が深刻な圧力を受けている。
