Habitat & Geographic Range
Closed-Leaved Pondweed
Typically found in grasslands, wetlands, forests, and cultivated landscapes.
Distributed across Cuba, Norway, and United States.
Tigre
Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical grasslands and savannas, among 6 distinct biome types spanning the Neotropic and Oceanian realms. Populations are also found in montane and highland environments at higher elevations.
Distributed across Colombia and Ecuador. Currently classified as Endangered on the IUCN Red List, this species faces significant conservation challenges across its range.
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.
Tigre
El felino mas grande del mundo, el tigre puede superar los 300 kg y habita bosques desde el Extremo Oriente ruso hasta el Sudeste Asiatico. Es un depredador solitario de emboscada con su caracteristico pelaje naranja y negro a rayas que proporciona camuflaje entre la luz filtrada. Esta en Peligro Critico, con menos de 4.000 individuos que quedan en estado silvestre debido a la caza furtiva y la deforestacion.
