Amazon River Dolphin

The Amazon River Dolphin (Inia geoffrensis) is a species in the genus Inia. Its conservation status is listed as Data Deficient, indicating insufficient data for assessment. Typically found in diverse terrestrial and aquatic ecosystems.

Common Satingrass

<em>Muhlenbergia frondosa</em>, commonly known as wirestem muhly or common satingrass, is a native perennial grass in the family Poaceae, distributed across central and eastern North America, with records from Canada, the United States, and an introduced presence in Italy. The species typically inhabits moist to mesic woodlands, forest edges, floodplain forests, streambanks, disturbed sites, and thickets, preferring partial shade to full sun and moist, well-drained soils. It grows in loose, spreading clumps with wiry stems that can reach up to 100 centimeters, bearing narrow leaves and fine, diffuse panicles of small spikelets in late summer and autumn. The species is adapted to a range of soil conditions from fertile floodplain soils to disturbed ground and is tolerant of occasional flooding. It is currently listed as Not Evaluated on the IUCN Red List, reflecting limited formal global assessment. <em>Muhlenbergia frondosa</em> provides habitat structure and seed resources for small birds and invertebrates in woodland edge communities. The plant reproduces by seed and vegetatively through spreading rhizomes, often forming substantial colonies. Its fine-textured foliage and late-season seed plumes provide ornamental value. Biological traits such as average lifespan, body measurements, and dietary data remain poorly documented in standardized ecological databases.
