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/Puna Miner

The Common Miner, <em>Geositta cunicularia</em>, is a small terrestrial bird in the family Furnariidae, the ovenbirds, native to open habitats in South America, particularly the pampas, scrublands, and highland grasslands of Argentina, Chile, Peru, and adjacent countries. Despite the geographic origin data listing Norway, the species is a South American endemic. It is typically found in dry, open ground habitats including agricultural fields, sandy soils, and rocky areas, where it excavates burrow nests in earthen banks or flat ground. <em>Geositta cunicularia</em> has a plain brown plumage with a rufous wash on the wings and tail, a pale supercilium, and a thin, slightly decurved bill adapted for probing soil and leaf litter. The species is insectivorous, typically foraging on the ground for beetles, ants, and other small invertebrates. It runs rapidly across open ground when disturbed rather than taking flight. The Common Miner is assessed as Least Concern on the IUCN Red List given its broad range and stable population across South American grassland ecosystems. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
