clavellina

The clove pink or feathered pink (Dianthus plumarius) is a perennial flowering plant in the family Caryophyllaceae, native to rocky limestone habitats in central and southeastern Europe. The species is named for the clove-like fragrance of its flowers — an aroma produced by eugenol compounds — and for the distinctive feathery or plumed appearance of its deeply fringed petals, referenced by the Latin epithet plumarius. Plants grow as low-spreading mats or cushions from four to thirty centimeters tall, producing glaucous grey-green linear leaves and flowers in shades of white, pink, or occasionally bicolored, typically in late spring to midsummer. D. plumarius inhabits dry, calcareous rocky outcrops, scree slopes, stony grasslands, and cliff ledges in its native range, showing a preference for well-drained alkaline soils in open, sunny exposures. It is among the original parents of garden carnations, having been cultivated and hybridized in European horticulture for over five hundred years, and remains widely grown as an ornamental plant for borders, rock gardens, and cottage garden settings. The species has naturalized in parts of Britain and western Europe outside its native range. Pollinators including butterflies, moths, and bumblebees visit the flowers for nectar. D. plumarius has not been formally evaluated under IUCN Red List criteria and is listed as Not Evaluated, though wild populations in its core range in central Europe are considered stable within suitable rocky limestone habitats.

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.
