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 Leaf Weevil

The Common Leaf Weevil (<em>Phyllobius pyri</em>) is a beetle in the family Curculionidae, classified as Least Concern on the IUCN Red List. It is native to four Asian countries and thirty-three European countries, giving it one of the broadest distributions of any weevil species in the Palearctic biogeographic realm. The species typically inhabits temperate coniferous forests, montane grasslands, shrublands, and deserts and xeric shrublands across its extensive range. Adults are typically covered in metallic green or bronze scales that give them a distinctive appearance. They feed on the foliage of a wide range of deciduous trees and shrubs, with larvae developing in the soil where they feed on roots. The Common Leaf Weevil is occasionally regarded as an agricultural and horticultural pest due to its feeding on fruit trees and ornamental plants. Its vast European and Asian range and generalist feeding habits support its Least Concern assessment. Biological traits of this species remain poorly documented in the scientific literature.
