common greasewort

<em>Aneura pinguis</em>, commonly known as common greasewort, is a liverwort belonging to the genus Aneura within the family Aneuraceae. This cryptogamic plant inhabits ecosystems across Asia, Europe, and North America, thriving in moist or waterlogged environments. Its range encompasses Taiwan in Asia, six European countries, the United States in North America, and Brazil and Colombia in South America, indicating a broad geographic distribution across multiple continents. Common greasewort is assessed as Least Concern on the IUCN Red List. The species typically forms flat, ribbon-like thalli in damp habitats such as stream banks, wet rocks, and boggy ground. Biological traits of this species remain poorly documented in the scientific literature.

Common pricklypear

The Common Pricklypear, <em>Opuntia monacantha</em>, is a cactus in the family Cactaceae with a remarkably broad global distribution, naturalized across Africa, Asia, Europe, and throughout the Americas and Oceania. Native to South America, it has been introduced widely and is considered invasive in parts of its non-native range. The species is characterized by its flat, oval to elongated green cladodes bearing sparse but long spines and dense glochids at each areole. <em>Opuntia monacantha</em> typically grows in dry, disturbed habitats including coastal areas, roadsides, agricultural margins, and degraded scrublands, thriving in full sun and well-drained soils. It produces yellow flowers and small purplish-red fruits that are consumed by birds and mammals, facilitating seed dispersal across its wide range. The plant utilizes CAM photosynthesis, allowing it to minimize water loss in arid conditions. In some regions, the species is cultivated for its edible fruits and as a livestock fodder. It is assessed as Least Concern on the IUCN Red List given its abundance and broad distribution. Biological traits such as average lifespan, body size, and specific dietary preferences remain poorly documented for this species.
