Clinton's bulrush

Clinton's Bulrush, Schoenoplectus clintoni, is a perennial wetland sedge in the family Cyperaceae with a restricted distribution in parts of the northeastern United States, named in honor of DeWitt Clinton, an early American naturalist and statesman. Like other bulrushes in the genus Schoenoplectus, it grows in shallow water and wet soils at the margins of lakes, ponds, marshes, and slow-moving streams. The stems are triangular or round in cross-section, bearing clusters of small, brownish spikelets characteristic of the genus. Bulrushes provide critical ecosystem services in wetland habitats, stabilizing shorelines, filtering water, providing nesting cover for marsh birds, and furnishing food through their seeds and starchy rhizomes for waterfowl and mammals. Clinton's Bulrush is considered rare within its limited northeastern range and faces threats from wetland drainage, development, and invasive species including common reed (Phragmites australis) that displace native emergent vegetation. Wetland loss across the northeastern United States has significantly reduced the area of suitable habitat for specialist wetland plants. The species is protected or of concern in several states where it occurs.

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.
