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.

Collared Brushturkey

<em>Talegalla jobiensis</em>, the Collared Brushturkey, is a megapode in the family Megapodiidae. This species is assessed as Least Concern on the IUCN Red List. It is native to New Guinea, occurring in lowland and hill forests where it is typically found in dense rainforest habitats. Megapodes are notable for their unique thermoregulatory breeding strategy: instead of incubating eggs with body heat, they construct large mounds of organic material in which eggs are buried and incubated by the heat generated by decomposing vegetation. <em>Talegalla jobiensis</em> belongs to a group of brushturkeys restricted to the Australasian region. Diet information typically includes invertebrates, seeds, and fallen fruit foraged from the forest floor, as is common in megapodes, though specific diet data for this species are not enumerated in available records. Biological measurements including average length, weight, and lifespan are not specified in available data. Biological traits of this species remain poorly documented in the scientific literature. Its Least Concern status reflects stable populations within its New Guinea range.
