clusterleaf

Terminalia sericea, known as clusterleaf or silver terminalia, is a medium-sized deciduous tree in the family Combretaceae native to the savanna woodlands and bushveld of southern Africa, ranging from South Africa through Zimbabwe, Botswana, Namibia, and into Zambia and Mozambique. The species is a characteristic and abundant component of the broad-leaved miombo and mopane woodland systems of the region. Trees typically reach 6–12 meters in height, distinguished by their distinctive silvery-grey leaves clustered at branch tips, which account for the common name clusterleaf. The leaf undersides are covered with fine silky hairs giving a silver sheen that is particularly visible in sunlight and dry season conditions. Terminalia sericea is prized for its dense, durable hardwood, and extracts from the roots, bark, and leaves have extensive applications in traditional African medicine, being used to treat infections, stomach complaints, and malaria symptoms. Pharmacological research has confirmed antimicrobial and anti-inflammatory properties in the species. It produces small, winged fruits that are wind-dispersed across the savanna landscape. The species is assessed as Least Concern by the IUCN and remains common and widespread across its southern African range.

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.
