African elephant

地球上最大の陸上動物であるアフリカゾウは体重7,000 kgに達し、サハラ以南のサバンナ、森林、湿地に生息する。成熟した雌が群れを率いる高度に知的な社会構造を持ち、超低周波音やうなり声、接触によって意思疎通する。木を引き倒したり水飲み場を掘ったり種子を散布したりすることで生態系を形成するエンジニア種だが、象牙の密猟や生息地の喪失により個体数は減少しており、危急（VU）とされている。

Chroomonas collegionis is a species of cryptophyte alga in the family Chroomonadaceae, documented from freshwater environments. The specific epithet collegionis may refer to a collegiate institution or academic collection where the type specimen was described or preserved. Chroomonas species are small, biflagellate, unicellular eukaryotes that possess a plastid of secondary red algal origin, with a retained nucleomorph that is unique among eukaryotic algae. The cells of Chroomonas are typically ovoid, compressed, or slightly asymmetric in cross-section, with a ventral groove from which two unequal flagella emerge. The plastid occupies a large portion of the cell and contains photosynthetic pigments including chlorophyll a, chlorophyll c, alpha-carotene, and phycobiliproteins, whose precise combination determines the cell's color. Cryptophytes including Chroomonas collegionis contribute to primary production in freshwater ecosystems and are grazed by heterotrophic flagellates and ciliates, linking microbial primary production to higher trophic levels. The species is part of the diverse microalgal flora of European freshwater bodies and has been documented in phycological surveys of the region. It has not been assessed under IUCN criteria.
