Seevogelzecke

<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.

Eisbär

The largest land carnivore on Earth, polar bears can exceed 700 kg and are found across Arctic sea ice from Canada to Russia. Highly specialized marine mammals that rely on sea ice to hunt ringed and bearded seals. Excellent swimmers capable of covering vast distances in open water. Listed as Vulnerable, with populations under severe pressure from rapid Arctic sea ice loss due to climate change.
