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 dung beetle

<em>Aphodius pedellus</em>, a species of dung beetle in the family Scarabaeidae, is classified as Least Concern by the IUCN Red List, indicating a stable conservation outlook across its known range. The species has been documented in Denmark, Norway, Sweden, Switzerland, and the United States, with its distribution spanning virtually all terrestrial and freshwater biome types. As a member of the Aphodiini tribe, <em>Aphodius pedellus</em> typically inhabits pastures, meadows, and woodland edges where mammalian dung is available, as dung beetles in this genus rely on feces as both a breeding medium and a food resource. These beetles play a critical role in nutrient cycling and soil aeration, breaking down organic waste and accelerating the return of nutrients to the soil. Their burrowing activity beneath dung pats enhances soil structure and improves water infiltration. <em>Aphodius pedellus</em> is part of a guild of coprophagous insects that collectively support healthy agricultural and natural ecosystems across temperate Europe and North America. Biological traits of this species remain poorly documented in the scientific literature.
