Big Finner

Big Finner (Balaenoptera physalus) is classified as Endangered (EN) on the IUCN Red List. At high risk of extinction in the wild, with significant population decline and ongoing threats to survival.

Common Rue

<em>Ruta graveolens</em>, commonly known as common rue or herb-of-grace, is an aromatic, evergreen subshrub in the family Rutaceae. Native to the Balkan Peninsula and southwestern Europe, the species has been widely cultivated and naturalized across Europe, Asia, the Americas, and Australia for centuries. It typically grows in dry, rocky, well-drained soils in sunny positions, and is commonly found in gardens, roadsides, waste ground, and limestone outcrops. The plant produces small yellow-green flowers in dense, flat-topped clusters and distinctive blue-green, strongly aromatic compound leaves containing volatile oils. Common rue has a long history of medicinal and culinary use in Mediterranean cultures, though its essential oils can cause photosensitive skin reactions. The species is not currently evaluated on the IUCN Red List, reflecting limited formal assessment rather than documented threat. It is a hardy plant tolerant of poor soils and drought conditions once established. Pollination is typically carried out by insects attracted to the small but accessible flowers. The plant produces small, lobed seed capsules dispersed primarily by wind and gravity. Biological traits such as average lifespan, body measurements, and detailed dietary interactions remain poorly documented in standardized ecological databases for this species.
