Broad skate

The Broad Skate (Amblyraja badia) is a species in the genus Amblyraja. It is currently classified as Least Concern on the IUCN Red List. This species is recognized for its ecological significance within its native range.

Common Rush

<em>Juncus pylaei</em> is a perennial rush in the family Juncaceae, distributed in parts of North America and western Europe, with confirmed records from Canada, France, and the United States. The species typically inhabits wet, poorly drained habitats including marshes, wet meadows, stream margins, and bog edges, favoring acidic to neutral soils in temperate climatic zones. Like other members of the genus <em>Juncus</em>, it produces cylindrical, grass-like stems with inconspicuous wind-pollinated flowers arranged in loose to compact inflorescences. The plant is adapted to saturated soil conditions and may form part of wetland plant communities alongside sedges, other rushes, and moisture-tolerant grasses. <em>Juncus pylaei</em> is currently listed as Not Evaluated on the IUCN Red List, meaning it has not yet undergone formal assessment for conservation status. Its distribution across Canada and parts of the eastern United States and France suggests a relict or disjunct range pattern, though the factors underlying this distribution are not fully documented. The species contributes to wetland ecosystem structure by providing cover for invertebrates and small vertebrates and helping stabilize soft substrates. Biological traits such as average lifespan, body measurements, and detailed dietary or feeding interactions remain poorly documented in standardized ecological literature for this species.
