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.

Fly Agaric

El matamoscas (Amanita muscaria) es uno de los hongos más icónicos y reconocibles de la Tierra, con llamativos sombreros rojos con manchas blancas en los bosques boreales del hemisferio norte. A pesar de su apariencia de cuento de hadas, contiene potentes compuestos psicoactivos como muscimol y ácido iboténico y es moderadamente tóxico. Forma simbiosis micorrícicas esenciales con abedules, pinos y abetos, intercambiando nutrientes minerales por carbono y desempeñando roles fundamentales en el ciclo de nutrientes de los bosques boreales.
