Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and flooded grasslands and savannas, among 5 distinct biome types within the Neotropic biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Found in Ecuador. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Coelosphaerium dubium is a colonial planktonic cyanobacterium in the family Merismopediaceae, named for the taxonomic uncertainty surrounding its morphological boundaries with related species in the genus. Like its congeners, it forms spherical, gelatinous mucilaginous colonies in which cells are distributed at the periphery of a central hyaline matrix. The genus Coelosphaerium has historically been defined by gross morphological characteristics—colony shape, cell arrangement, and mucilage properties—but molecular phylogenetic analyses have substantially revised understanding of cyanobacterial diversity and systematics within this group. Coelosphaerium dubium has a relatively broad geographic distribution compared to some congeners, with records from freshwater bodies in Denmark, Norway, Sweden, and Taiwan, suggesting either a wide ecological tolerance or cryptic species diversity within the taxon. It inhabits lentic and slow-flowing freshwater environments, particularly stratified lakes and ponds where thermal and chemical gradients allow cyanobacterial cells equipped with gas vesicles to adjust their buoyancy and optimise light exposure. As a primary producer in these aquatic ecosystems, it contributes to nutrient cycling and forms part of the phytoplankton community grazed by zooplankton. No formal conservation assessment has been undertaken for this species by the IUCN.

giraffe

地球上で最も背の高い動物であるキリン（Giraffa camelopardalis）は体高が5.5mに達し、体重は最大1,750kgにもなる。すべての哺乳類と同じ7個の頸椎からなる長い首は、アフリカのサバンナや疎林のアカシアの木に食物を求めて進化した。永続的な絆を持たない緩やかな群れで生活する社会的動物で、超低周波音と身振りで意思疎通する。生息地の喪失と密猟により個体数が減少している危急種である。
