Common Milkwort

Common Milkwort (<em>Polygala vulgaris</em>) is a small flowering plant in the genus <em>Polygala</em>, family Polygalaceae. It is distributed across Europe, North America, and Oceania, with confirmed presence in countries including Australia, Belgium, Canada, Denmark, and Finland. Typically found in diverse terrestrial habitats ranging from tropical forests to temperate grasslands, this species favors calcareous grasslands, heathlands, and other open, well-drained habitats. Common Milkwort produces small flowers in shades of blue, pink, or white, and is associated with traditional grassland communities. Currently classified as Vulnerable on the IUCN Red List, the species faces significant conservation challenges across its range, likely driven by habitat loss through agricultural intensification and the decline of traditionally managed grasslands. Specific biological measurements such as lifespan, length, and weight are not documented in available records. The genus name <em>Polygala</em> derives from Greek meaning "much milk," reflecting a historical belief that the plant could increase milk production in livestock.

gray wolf

灰狼是分布最广的野生犬科动物，分布范围从北美横跨欧亚大陆，栖息于冻原、森林和草原等多种生境。高度社会化的动物，以由占优势的繁殖对领导的家族群体生活。作为关键捕食者，狼调节猎物种群并深刻影响生态系统结构，黄石公园的重引入项目对此有充分证明。曾遭到严重迫害，但目前许多地区的种群正在恢复。
