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.

Colombian Frog

<em>Leptodactylus colombiensis</em>, commonly known as the Colombian Frog, is an amphibian species belonging to the genus <em>Leptodactylus</em> within the family Leptodactylidae, a diverse group of neotropical frogs. This species is assessed as Least Concern by major conservation bodies, suggesting that its populations are currently stable and not at heightened extinction risk. It has been documented in Colombia and Venezuela, where it inhabits freshwater-associated environments, moist forests, and wetland habitats. Members of the genus <em>Leptodactylus</em> are known for constructing foam nests in which eggs are deposited, a reproductive strategy that protects developing embryos from desiccation and predators. These frogs are generally associated with humid lowland and foothill environments near water bodies. Dietary information specific to this species has not been documented, though leptodactylid frogs typically prey on invertebrates and small vertebrates. Biological traits of this species remain poorly documented in the scientific literature. Continued monitoring of habitat conditions in Colombia and Venezuela will be important for ensuring the long-term persistence of <em>Leptodactylus colombiensis</em>.
