Habitat & Geographic Range

Bamboo bear

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, temperate coniferous forests, and temperate broadleaf and mixed forests, among 7 distinct biome types spanning the Indomalayan and Palearctic realms. Populations are also found in montane and highland environments at higher elevations.

Range

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

Comb-Leaved Mermaidweed

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Distributed across Canada and Cuba.

Bamboo bear

Iconic black-and-white bear of the mountain bamboo forests of central China, giant pandas can weigh up to 125 kg and spend up to 14 hours daily consuming bamboo, which comprises 99% of their diet despite belonging to the order Carnivora. Solitary and elusive, they have a pseudo-thumb for gripping bamboo stems. Downgraded from Endangered to Vulnerable in 2016 following successful conservation and breeding programs.

Comb-Leaved Mermaidweed

<em>Proserpinaca pectinata</em>, the comb-leaved mermaidweed, is a semi-aquatic flowering plant in the family Haloragaceae, assessed as Least Concern on the IUCN Red List. It occurs in the freshwater wetlands of Canada and Cuba, growing in shallow water, pond margins, bogs, and wet meadows. The species is notable for its heterophylly, producing distinctly different leaf forms above and below the waterline: emergent leaves are linear or toothed while submerged leaves are deeply pinnately divided, resembling a comb — the feature that gives the plant its common name. This leaf-form plasticity is an adaptation to variable water levels in its riparian and wetland habitat. <em>P. pectinata</em> is a rooted aquatic plant that grows in nutrient-poor to moderately fertile waters and is sometimes cultivated in freshwater aquaria for its ornamental submerged foliage. No quantitative biological metrics are available for this species.
