Canadian beaver

北米最大の齧歯類であるカナダビーバーは体重32kgにも達し、カナダ・米国北部の河川、湖沼、湿地に生息する優れた生態系エンジニアです。木を倒して数百メートルに及ぶダムを造ることで池を形成し、数百種の生息環境を提供します。その巣穴や運河は流域全体を変化させます。かつては毛皮のために絶滅寸前まで狩られましたが、個体数は大きく回復しています。

Collared Mongoose

The Collared Mongoose, known scientifically as <em>Herpestes semitorquatus</em>, is a small carnivorous mammal belonging to the family Herpestidae. <em>Herpestes semitorquatus</em> is characterised by a distinctive pale collar or band of lighter fur around the neck region, which gives the species its common name and differentiates it from other mongoose species within the genus. Mongooses of the genus Herpestes are typically agile, terrestrial predators that inhabit a range of forested and scrubland environments. They are generally known to feed on invertebrates, small vertebrates, and eggs. Detailed biological traits including typical lifespan, body length, and weight are poorly documented for this species in available literature. The Collared Mongoose is currently assessed as Near Threatened on the IUCN Red List, indicating that while the species does not yet qualify as threatened, it is considered to be close to qualifying, and monitoring of population trends is warranted.
