Climbing Star-apple

Climbing Star Apple, Landolphia species, is a genus of woody, climbing lianas and scrambling shrubs in the family Apocynaceae native to tropical and subtropical Africa. Landolphia species were historically important as sources of wild rubber; the latex from cut stems and roots was a major commercial rubber source in central Africa before Hevea brasiliensis became dominant, and its exploitation under Belgian colonial rule in the Congo Free State caused widespread human rights abuses in the late 19th century. The common name 'star apple' relates to the edible fruits produced by several species, which are large, yellow or greenish, with a sweet pulp surrounding the seeds. The fragrant flowers are white and produced in terminal clusters, pollinated by insects. Landolphia species grow in tropical forest margins, secondary forest, and gallery forest across sub-Saharan Africa, where they play an important role in forest structure by connecting canopy layers. The edible fruits are consumed by wildlife and by local human communities. Several Landolphia species are used in traditional medicine for treating a variety of ailments. Conservation status varies among species; some with restricted ranges in heavily deforested areas face threat from habitat loss.

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.
