The Bishop ray (Aetobatus narinari) is a species in the genus Aetobatus. It is currently classified as Near Threatened on the IUCN Red List. Native to Asia and South America, inhabiting ecosystems characteristic of the region.

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.
