Coastal Pleurothyrium

Coastal pleurothyrium (Pleurothyrium costanense) is a tree in the family Lauraceae, native to the Pacific coastal forests of Costa Rica and adjacent Panama. It grows in tropical lowland rainforest and pre-montane forest habitats at elevations generally below 800 metres, where it forms part of the high canopy layer. The genus Pleurothyrium is characterised by alternate leaves with a leathery texture, small flowers borne in paniculate inflorescences, and fleshy fruits enclosed in a cupule—typical of the broader laurel family. As a member of the Lauraceae, the species likely plays a role in forest succession and provides fruits consumed by birds and mammals. Central American coastal forests are under pressure from deforestation for agriculture and cattle ranching, but Pleurothyrium costanense is assessed as Least Concern by the IUCN, indicating sufficient population size and distribution to withstand current threats. The species is part of the diverse laurel flora that defines Central American cloud forests and wet lowland ecosystems, and its conservation is linked to the broader protection of Costa Rican biodiversity hotspots.

koala

オーストラリア東部・南東部を代表する有袋類で、体重は最大15kgに達し、低カロリーのユーカリの葉食から得るエネルギーを節約するために1日最大22時間を睡眠に費やす。他の哺乳類の多くを死に至らしめる有毒なユーカリ成分を処理するために高度に特化しており、解毒に特別に適応した腸内微生物叢を持つ。クラミジア感染症、生息地の伐採、気候変動により個体数が激減し、2022年に絶滅危惧種に指定された。
