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 Lesser Toad

<em>Rhinella granulosa</em>, commonly known as the common lesser toad, is a small amphibian belonging to the family Bufonidae. This species is native to Colombia and is typically found in freshwater ecosystems, moist tropical forests, and wetland habitats. It inhabits lowland and foothill environments where moisture is consistently available throughout the year. The common lesser toad is classified as Least Concern on the IUCN Red List, indicating that its populations are currently stable and not under significant threat. Like other members of the genus Rhinella, it is typically insectivorous, feeding on small invertebrates found in its humid forest floor environment. The species plays an important ecological role as both predator of insects and prey for larger animals within its native Colombian range. Its granular skin texture, referenced in its scientific name, provides some protection from predators. Population trends remain stable, and the species benefits from the relative abundance of suitable freshwater and forest habitats across its range in Colombia.
