Habitat & Geographic Range

American Flamingo

Habitat

Typically found in various aerial, terrestrial, and aquatic environments.

Range

Found across Europe (10 countries) and South America (Colombia, Ecuador, Venezuela).

Compact Stonewort

Habitat

Native to Asia and Europe and North America, inhabiting ecosystems characteristic of the region.

Range

Distributed across Brazil, Norway, Sweden, Taiwan, and United States.

American Flamingo

The most vibrantly colored flamingo species, American flamingos display brilliant scarlet-pink plumage from the carotenoid pigments in their crustacean diet. Found in Caribbean coastal lagoons, salt pans, and mangrove swamps from the Bahamas and Florida through Central America and the Galapagos. Highly gregarious, they nest in huge colonies on mudflat mounds. Their distinctive deep pink color is used to signal health and reproductive quality to potential mates.

Compact Stonewort

<em>Nitella tenuissima</em>, a stonewort formerly found in fresh and brackish water habitats, was a member of the charophyte family Characeae — the algal lineage most closely related to land plants. Historical records document its occurrence across Brazil, Norway, Sweden, Taiwan, and the United States, where it inhabited clear, oligotrophic lakes, ponds, and slow-flowing water bodies with low nutrient levels. Like other Nitella species, it was a delicate, translucent, submerged aquatic plant lacking the calcium carbonate encrustation of related genera, forming low-growing mats on soft sediments in well-illuminated shallow water. The species played a role in aquatic ecosystems by stabilising lake sediments, contributing to water clarity, and providing microhabitat for invertebrates and small aquatic organisms. <em>Nitella tenuissima</em> is classified as Extinct by the IUCN, having not been recorded from any of its former localities despite targeted searches. The primary causes of its extinction are believed to be widespread eutrophication of freshwater habitats driven by agricultural nutrient runoff and sewage discharge, which eliminated the clear, nutrient-poor conditions on which the species depended. The loss of this stonewort is emblematic of the broader decline of freshwater charophyte diversity across the Northern Hemisphere. Biological traits including historical morphological measurements and reproductive parameters are documented only in sparse historical herbarium specimens and early botanical literature.
