Cinnamon antechinus

The cinnamon antechinus (Antechinus leo) is a small marsupial in the family Dasyuridae, endemic to northeastern Queensland, Australia, particularly the Cape York Peninsula. It inhabits tropical and subtropical rainforest and forest margins at low elevations, sheltering in tree hollows, dense vine tangles, and fallen logs. Like all antechinuses, it is a specialist insectivore, consuming beetles, cockroaches, moths, and other invertebrates, and occasionally small lizards. The cinnamon antechinus is named for its rich cinnamon-brown dorsal fur. A remarkable feature shared by all antechinus species is semelparous reproduction: males undergo a catastrophic physiological decline and die shortly after a brief, intense mating season in winter, leaving only the pregnant females to carry the population into the next generation. This extreme reproductive strategy results in completely male-free populations for most of the year. The species is classified as Least Concern by the IUCN, with populations within Cape York's relatively intact tropical forest. However, like all antechinuses, it faces threats from feral predators (cats and foxes), habitat degradation, and altered fire regimes. Climate change poses a long-term risk by shrinking the cool, moist forest habitats this species depends on. Genetic studies of Australian antechinuses have revealed considerable cryptic diversity.

コンゴウインコ

南北アメリカ大陸で最も鮮やかな色彩を誇る鳥の一つであるコンゴウインコ(Ara macao)は、鮮烈な赤・黄・青の羽毛と翼開長最大1メートルの大きな翼を持ちます。メキシコからボリビアにかけての湿潤な低地森林に生息し、高い知性を持ち、最長75年の長寿で生涯を通じてつがいを形成します。種子の毒素を無害化するためにミネラル豊富な土を摂取するクレイ・リックまで長距離を移動します。軽度懸念に指定されていますが、生息地の喪失とペット取引により地域的に脅威にさらされています。
