Coastal Ragweed

Coastal ragweed (Ambrosia hispida) is a perennial herb in the family Asteraceae, native to the coastal dunes, sandy beaches, and cays of Cuba, the Bahamas, and the wider Caribbean region. It grows in pioneer beach and dune vegetation, often forming spreading colonies that help stabilise loose coastal sands. Like other members of the genus Ambrosia, it bears inconspicuous greenish-white flowers arranged in racemes; male flower heads produce wind-dispersed pollen that can trigger allergic rhinitis in sensitive individuals. The deeply lobed, hispid leaves are adapted to reflect intense solar radiation and tolerate salt spray. Coastal ragweed plays an ecological role in early dune succession, binding sand and enabling other plant species to establish. The genus is widespread globally, with several Ambrosia species considered noxious weeds in agricultural settings, though Ambrosia hispida is restricted to its native Caribbean coastal range. The IUCN assesses it as Least Concern, reflecting adequate population size across its Caribbean coastal distribution. Pressure from coastal development and tourism infrastructure poses a localised threat to dune communities it inhabits.

Common Grapevine

<em>Vitis vinifera</em>, commonly known as the common grapevine, is a woody climbing vine belonging to the genus Vitis within the family Vitaceae. This species occupies diverse terrestrial habitats from tropical forests to temperate regions and has one of the widest cultivated distributions of any plant species. Its range spans Africa, Asia including India, Taiwan, and Yemen, twenty-two European countries, North America, five Oceanian territories, and five South American nations. Common grapevine is assessed as Least Concern on the IUCN Red List. The species is of enormous agricultural and cultural significance, being the primary source of wine grapes cultivated globally for millennia. Wild populations typically colonize woodland edges and scrubland. Biological traits of this species remain poorly documented in the scientific literature.
