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 Carder Bee

<em>Bombus pascuorum</em>, commonly known as the common carder bee, is a bumblebee species found across Europe, with documented occurrences in Belgium, Denmark, Norway, Portugal, Sweden, and additional European countries. It typically inhabits all terrestrial and freshwater environments, often foraging across a wide range of flowering plants in meadows, gardens, hedgerows, and farmland. The species is classified as Least Concern on the IUCN Red List, indicating a broadly stable global population. Common carder bee belongs to the genus <em>Bombus</em> within the family Apidae and is one of the more widely distributed bumblebee species in Europe. It often nests above ground in dry grass, moss, or other plant material, building compact nests characteristic of carder bees. As a generalist pollinator, it visits a diverse range of flowering species and contributes meaningfully to ecosystem pollination services. Biological traits such as average lifespan, body length, and mass of this species remain poorly documented in the scientific literature.
