coast amaranth

Coast amaranth (Amaranthus pumilus) is an annual herb in the family Amaranthaceae, native to the Atlantic and Gulf coasts of the eastern United States, where it once grew on coastal foredunes, beach strand, and shell-hash substrates above the high tide line from New York south to South Carolina. It is a low-growing, fleshy plant with small, rounded leaves and inconspicuous green flowers typical of the genus. Coast amaranth is assessed as Extinct in the Wild by the IUCN, as it has not been reliably documented from wild populations since the mid-20th century; the last confirmed collections date to the 1960s. The species' decline and likely extinction resulted from intense human pressure on Atlantic coastal habitats through shoreline development, beach stabilisation, vehicular traffic on beaches, and increased storm frequency disrupting pioneer dune vegetation. It is federally listed as Threatened in the United States, though this listing predates confirmed extinction in the wild. A small number of ex-situ accessions may exist in botanical garden collections. Genetic material and seed banking efforts represent the only remaining conservation options for this critically reduced species.

Common Dwarf Bonneted Bat

<em>Eumops bonariensis</em>, the common dwarf bonneted bat, is a small molossid bat classified as Least Concern on the IUCN Red List, suggesting its populations are currently not under significant threat. The species has been recorded in Venezuela and is associated with diverse terrestrial and aquatic habitats, reflecting the broad ecological tolerance typical of many molossid bats. <em>Eumops bonariensis</em> belongs to the free-tailed bat family Molossidae and is characterized by its distinctive bonnet-shaped ears that extend over the forehead. Like other members of its genus, this species is adapted for fast, high-altitude flight and typically forages for flying insects in open airspace above forest canopies, wetlands, and urban areas. Molossid bats are known for their echolocation calls, which they use to detect and pursue prey during nocturnal foraging bouts. The species typically roosts in tree cavities, rock crevices, or man-made structures, forming small to moderate-sized colonies. Its insectivorous habits make it an important regulator of insect populations in tropical and subtropical ecosystems. Biological traits of this species remain poorly documented in the scientific literature.
