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.

Dyadobacter jiangsuensis는 Cytophagaceae과에 속하는 그람음성 오렌지색 색소를 가진 세균으로, 중국 장쑤성 토양 샘플에서 처음 분리되었습니다. 호기성이며 간균 형태이고 비운동성으로, 토양 환경에서 다당류를 분해하는 능력을 가집니다. Dyadobacter 속은 육상 및 민물 서식지에 광범위하게 분포하는 다양한 Bacteroidetes 문의 일부입니다.
