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 seabird tick

<em>Ixodes uriae</em>, the common seabird tick, is a hard tick in the family Ixodidae, order Ixodida, distributed across subarctic and subantarctic regions with records from Norway and Sweden. This species is an obligate ectoparasite that specializes in feeding on colonial seabirds, including auks, penguins, and petrels, making it one of the few tick species with a genuinely circumpolar distribution tied to its avian hosts. <em>Ixodes uriae</em> typically infests birds in their nesting colonies, where dense aggregations and repeated site fidelity by hosts facilitate transmission. Beyond its direct parasitic impact, this tick serves as a vector for various pathogens, including Borrelia spirochetes and tick-borne encephalitis-related viruses, making it of scientific interest for disease ecology in seabird populations. The species has not been formally evaluated by the IUCN, and its conservation status remains Not Evaluated. Biological traits for this species remain poorly documented in the scientific literature, including comprehensive data on average lifespan under natural conditions, body dimensions across life stages, weight, and the full range of its host and pathogen associations.
