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.

Closed-Leaved Pondweed

Habitat

Typically found in grasslands, wetlands, forests, and cultivated landscapes.

Range

Distributed across Cuba, Norway, and United States.

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.

Closed-Leaved Pondweed

Closed-leaved pondweed refers to aquatic plants in the genus Potamogeton (family Potamogetonaceae) characterized by leaves in which the sheath margins are fused to form a closed tube around the stem, rather than remaining open as in many related species. These submerged or floating-leaved aquatics grow in ponds, lakes, slow-moving rivers, and ditches across temperate regions of Europe, Asia, and North America. The distinctive closed leaf sheath is a key taxonomic character distinguishing certain Potamogeton species and provides structural support to stems in flowing water. Pondweeds are ecologically vital components of freshwater ecosystems, providing oxygen through photosynthesis, stabilizing sediments with their root systems, offering refuge for invertebrates and small fish among submerged stems, and forming important foraging habitat for migratory waterfowl that consume the starchy tubers and seeds. Many pondweed species have declined due to water quality deterioration from nutrient enrichment, increased turbidity, mechanical disturbance from boat traffic, and invasive aquatic plant competition in freshwater habitats across Europe and North America.
