collared notchwort

The Collared Notchwort, known scientifically as Mesoptychia collaris, is a liverwort belonging to the family Jungermanniaceae within the class Jungermanniopsida. Mesoptychia collaris is a bryophyte — a non-vascular land plant — and represents one of the leafy liverworts, characterised by flattened, leaf-like structures arranged along creeping stems. This species is associated with moist, shaded habitats typical of temperate regions, including areas of Europe and North America. It is reported to occur in Norway, Sweden, and the United States. Like other liverworts, Mesoptychia collaris plays a role in moisture retention and habitat structure in the ecosystems it inhabits. Detailed biological traits including typical lifespan measures and physical dimensions are poorly documented for this species in available literature. The Collared Notchwort is currently assessed as Least Concern on the IUCN Red List.

最も広い分布域を持つ野生のイヌ科動物であるハイイロオオカミは、北アメリカからユーラシアにかけてのツンドラ、森林、草原などの多様な生息地に分布します。優位な繁殖ペアに率いられた家族単位の群れで生活する高度に社会的な動物です。キーストーン捕食者として獲物個体群を調整し、生態系の構造を根本的に形成することは、イエローストーンでの再導入により実証されています。かつて激しく迫害されましたが、多くの地域で個体群は回復しつつあります。
