Habitat & Geographic Range

African elephant

Habitat

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

Range

Found in Kenya. 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.

African elephant

O elefante africano, o maior animal terrestre da Terra, pode atingir 7.000 kg e habita savanas, florestas e zonas húmidas da África subsaariana. Com estruturas sociais complexas lideradas por matriarcas, comunica através de infrassons, rugidos e contacto físico. Como engenheiro do ecossistema, modela o habitat arrancando árvores, escavando poços de água e dispersando sementes. Está classificado como Vulnerável (VU), com populações em declínio devido à caça furtiva de marfim e à perda de habitat.

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.
