Habitat & Geographic Range

Coastal Rocket Frog

Habitat

Typically found in freshwater habitats, moist forests, and wetlands.

Range

Found in Venezuela. Currently classified as Vulnerable on the IUCN Red List, this species faces significant conservation challenges across its range.

Common Periwinkle

Habitat

Typically found in diverse terrestrial habitats from tropical forests to temperate regions.

Range

Widely distributed across Africa (South Africa), Asia (Armenia, Japan, Turkey), Europe (18 countries), North America (Canada, Mexico, United States), Oceania and the Pacific (Australia), and South America (Brazil).

Coastal Rocket Frog

Coastal rocket frog (Allobates bromelicola) is a small terrestrial frog in the family Allophrynidae (formerly placed in Dendrobatidae), endemic to coastal lowland forests of Venezuela. Despite its placement near poison dart frogs, Allobates species are non-toxic. This species inhabits the humid leaf litter and bromeliads of coastal Venezuelan forests, where adults care for egg clutches and transport tadpoles to small water bodies including bromeliad phytotelmata. The genus Allobates is widespread across Amazonian and coastal South American forests, characterised by vocal males, ground-level activity, and close parental care. Coastal rocket frog is assessed as Vulnerable by the IUCN, primarily due to restricted range, habitat loss from deforestation for agriculture, livestock grazing, and urban expansion along Venezuela's coast. Climate change poses an additional threat through altered precipitation patterns affecting its bromeliad microhabitats. The species' specific association with bromeliads makes it particularly sensitive to vegetation structure loss. As with many narrowly endemic amphibians, ex-situ conservation programmes and improved habitat protection within its range are considered important management priorities.

Common Periwinkle

<em>Vinca minor</em>, known as the common periwinkle or lesser periwinkle, is a trailing evergreen subshrub in the family Apocynaceae, widely recognised by its glossy dark-green leaves and distinctive violet-blue, five-petalled flowers. Native to central and southern Europe, it has been extensively introduced and naturalised across a remarkably wide geographic range, with established populations documented across Africa, Asia, Europe, North America, Oceania, and South America, making it one of the more globally distributed ornamental escapees. The species typically colonises woodland edges, hedgerows, roadsides, and disturbed ground, often forming dense ground-covering mats that can suppress native vegetation. <em>Vinca minor</em> is tolerant of shade and a variety of soil types, contributing to its success as both a garden plant and an invasive species in some regions. It is assessed as Least Concern on the IUCN Red List given its vast distribution and adaptability. In many countries outside its native range, it is considered invasive. Biological traits such as average lifespan, precise growth dimensions, and detailed physiological parameters remain poorly documented in the scientific literature. The species contains alkaloids including vincamine, which have been investigated for pharmaceutical applications.
