Habitat & Geographic Range

Common Mint

Habitat

Found across multiple habitat types including tropical and subtropical moist broadleaf forests, tropical and subtropical dry broadleaf forests, and tropical and subtropical coniferous forests, among 4 distinct biome types within the Indomalayan biogeographic realm. Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Seychelles), Asia (4 countries), Europe (10 countries), North America (Canada, United States), and South America (Brazil).

Common Water Rat

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

Common Mint

Common Mint (<em>Mentha arvensis</em>), also known as corn mint or field mint, is a perennial herbaceous plant in the genus <em>Mentha</em>, family Lamiaceae. It is widely distributed across Africa, Asia, Europe, North America, and South America, with confirmed presence in countries including Belarus, Belgium, Brazil, Canada, and Czech Republic. Its range encompasses the Seychelles in Africa, four Asian countries, and ten European nations. The species is found across multiple habitat types, including tropical and subtropical moist broadleaf forests, dry broadleaf forests, and coniferous forests, occurring within at least four distinct biome types in the Indomalayan realm. Common Mint is classified as Least Concern on the IUCN Red List. As a member of the mint family, it typically produces aromatic foliage rich in menthol, and has historically been used in culinary and medicinal applications across many cultures. It typically spreads vegetatively through stolons and rhizomes in addition to producing seed. Detailed measurements of lifespan, length, and weight are not documented in available records.

Common Water Rat

<em>Hydromys chrysogaster</em>, commonly known as the common water rat or rakali, is a semi-aquatic rodent in the family Muridae, native to Australia and New Guinea. It is classified as Least Concern by the IUCN, reflecting its relatively stable population across a broad range of freshwater and estuarine habitats on the Australian continent and associated islands. The species typically inhabits the banks of rivers, lakes, wetlands, and estuaries, where it constructs burrows in streambanks. It is highly adapted for an aquatic lifestyle, with partially webbed hind feet, a flattened head, and a dense waterproof coat. <em>Hydromys chrysogaster</em> is a carnivore, typically feeding on fish, crustaceans, mussels, frogs, and aquatic invertebrates, which it often carries to elevated feeding platforms to consume. The species is nocturnal and crepuscular, most active during early morning and evening hours near the water's edge. Biological traits including average lifespan, body length, and weight remain poorly documented in standardized databases, though adults are generally robust for a rodent, reportedly reaching body lengths of 20–35 cm excluding the tail. Geographic range details for this particular record remain incompletely documented in available data sources. Ecologically, the common water rat is an important apex predator in small-scale freshwater food webs and serves as an indicator species for wetland health in Australian riparian systems.
