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.

ハイバラエメラルドハチドリ

アカオハチドリ(Amazilia tzacatl)は中央アメリカと南アメリカ北西部で最もよく見られるハチドリの一つで、緑色の上面と診断的な明るい赤褐色の尾が特徴的な中型種である。メキシコからエクアドル、トリニダードにかけて、海抜0~2,100mの林縁、庭園、農園、二次林など多様な環境に生息する。給餌台や花の咲く植物の縄張りを積極的に守り、分布域全体の庭でしばしば目撃される。軽度懸念に指定されている。
