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 parlatoria scale

<em>Parlatoria proteus</em> is an armored scale insect in the family Diaspididae, found in Japan, Taiwan, ten European countries, and the United States. It is a cosmopolitan pest species associated with a wide range of host plants across virtually all terrestrial habitats where cultivated trees and shrubs are present. The species infests the bark, leaves, and fruit of numerous hosts, including citrus, palms, figs, and ornamental plants, by piercing plant tissue and extracting sap. Infestations can lead to chlorosis, dieback, and fruit damage in heavily colonized plants. Female scale insects are sedentary once settled, protected beneath a waxy armored cover produced from molted exoskeletons and secretions. Males are short-lived winged forms involved only in reproduction. Conservation status has not been formally evaluated by the IUCN, consistent with its status as a widely distributed and economically significant agricultural pest rather than a species of conservation concern. Biological traits including average lifespan, body measurements, and detailed ecological dietary data remain poorly documented in standardized databases for this scale insect. <em>Parlatoria proteus</em> is managed through biological control agents, horticultural oils, and systemic insecticides in affected agricultural systems.
