Common White Ash

Bersama tysoniana, commonly known as the common white ash or Tyson's bersama, is a tree in the family Melianthaceae, native to southern Africa. It is classified as Least Concern by the IUCN. The species is found in forest margins, riverine woodland, and moist montane habitats within its native range on the African continent, where it typically grows as a small to medium-sized tree. Bersama tysoniana produces pinnately compound leaves with numerous leaflets, small white to cream-colored flowers arranged in terminal racemes, and distinctive capsular fruits that split to reveal seeds with fleshy orange-red arils. The arils are attractive to birds, which serve as the primary seed dispersers, facilitating natural regeneration within forest ecosystems. The wood is reportedly hard and durable, and the plant has been used in traditional medicine within its native range. Geographic range details and associated country records for this particular entry remain incompletely documented in available data sources. Biological traits including average lifespan, tree height, and mass remain poorly documented in standardized databases. Ecologically, Bersama tysoniana contributes to the structural complexity of southern African forest edge communities and supports a range of frugivorous birds and invertebrates through its fruit production, playing a modest but consistent role in forest food webs and seed dispersal networks.

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。
