Populations are also found in montane and highland environments at higher elevations.

Range

Widely distributed across Africa (Algeria, Libya), Asia (5 countries), Europe (12 countries), North America (Cuba), Oceania and the Pacific (Australia, New Zealand), and South America (4 countries).

Common Water Rat

Habitat

Typically found in diverse terrestrial and aquatic ecosystems.

common-cypress

<em>Cupressus sempervirens</em>, the common cypress, is a coniferous evergreen tree in the family Cupressaceae. Native to the Mediterranean region and widely distributed across Europe, Africa, Asia, North America, Oceania, and South America, this species typically thrives in temperate broadleaf and coniferous forest habitats within the Palearctic realm. The common cypress is characterized by its distinctive columnar or pyramidal growth form, with dark green, scale-like leaves arranged in dense, flattened sprays. It often grows on well-drained, rocky or alkaline soils and typically tolerates drought and heat, making it well adapted to Mediterranean climates. The tree produces small, rounded cones that take approximately two years to mature. <em>Cupressus sempervirens</em> is widely cultivated as an ornamental tree and windbreak, and its durable, aromatic wood has historically been valued for construction and furniture. This species is also associated with funerary traditions in many Mediterranean cultures. Its conservation status is assessed as Least Concern, reflecting its broad range and stable populations across multiple continents.

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.
