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.

ミミグロハチドリ

ハチドリの中で単色または虹色の羽毛が主流な中、珍しく班点や斑点のある下面を持つ中型のハチドリで、コロンビアとベネズエラからボリビア南部まで標高900〜3,000メートルのアンデスの雲霧林と林縁に生息する。班点のある下面パターンは、苔に覆われた樹皮に止まる際に卓越した迷彩効果を提供する。蜜と小型節足動物を採食し、アンデスの着生植物の重要な花粉媒介者として機能する。
