北极发生的快速气候变化可能会影响具有重要生态和文化意义的北方鱼类的饮食。在这里，对北美北极地区发现的八种鱼类（重点是因纽特努南加特）完成了系统的文献综述，以确定主要猎物、总结摄食策略并突出数据差距。北极红点鲑 ( Salvelinus alpinus )、Dolly Varden 红点鲑 ( Salvelinus malma )、湖鳟 ( Salvelinus namaycush )、公牛鳟 ( Salvelinus confluentus )、Inconnu ( Stenodus leucichthys )、白鲑 ( Coregonus clupeaformis )、宽白鲑 ( Coregonus nasus ) 和江鳕 ( Lota lota), 由于其生态和文化重要性而被选为感兴趣的物种。审查的 74 项研究表明，这些物种是通才饲养者，表现出广泛的饮食生态位，以及当它们与重叠物种同时出现时通过分配资源来避免竞争性相互作用的趋势。在沿海、湖泊和河流系统中，最常食用的猎物是昆虫（双翅目属），以及诸如杜鹃（科：鲉科）等底栖饲料鱼。昆虫是河流系统的主要猎物，与湖泊相比，河流系统的饮食似乎更为普遍。沿海水域的溯河物种最常以各种甲壳类动物和饲料鱼为食。底栖饲料鱼、昆虫、浮游动物和软体动物是北极湖泊中广泛食用的猎物。江鳕、因康努、和居民多莉瓦登拥有最专业的喂养策略，部分原因是它们的栖息地要求和形态，而湖鳟鱼和居民北极红点鲑通常在湖泊中形成多种生态型，其中一些具有不同的摄食行为。强调了北方鱼类营养生态学方面的知识缺口，特别是河流系统和冬季觅食行为。本综述旨在为有关气候变化对热带鱼类生态影响的预测提供信息，并指导未来的研究。特别是包括河流系统和冬季觅食行为。本综述旨在为有关气候变化对热带鱼类生态影响的预测提供信息，并指导未来的研究。特别是包括河流系统和冬季觅食行为。本综述旨在为有关气候变化对热带鱼类生态影响的预测提供信息，并指导未来的研究。

A systematic review of the trophic ecology of eight ecologically and culturally important fish species in the North American Arctic

Rapid climate change occurring in the Arctic may affect the diet of ecologically and culturally important northern fish species. Here, a systematic literature review was completed for eight fish species found across the North American Arctic, with a focus on Inuit Nunangat, to identify major prey items, summarize feeding strategies, and highlight data gaps. Arctic Char (Salvelinus alpinus), Dolly Varden Char (Salvelinus malma), Lake Trout (Salvelinus namaycush), Bull Trout (Salvelinus confluentus), Inconnu (Stenodus leucichthys), Lake Whitefish (Coregonus clupeaformis), Broad Whitefish (Coregonus nasus), and Burbot (Lota lota), were selected as species of interest due to their ecological and cultural importance. The 74 studies reviewed indicate that these species are generalist feeders that demonstrate wide dietary niches, as well as the tendency to avoid agonistic interactions by partitioning resources when they co-occur with an overlapping species. Across coastal, lacustrine, and riverine systems, the most commonly consumed prey items are insects (Diptera spp.), as well as benthic forage fishes such as sculpins (Family: Cottidae). Insects are major prey items in riverine systems, where diets appear to be more generalized, compared to lakes. Anadromous species in coastal waters most commonly feed on various crustaceans and forage fishes. Benthic forage fishes, insects, zooplankton, and mollusks are widely consumed prey items in Arctic lakes. Burbot, Inconnu, and resident Dolly Varden had the most specialized feeding strategies, due in part to their habitat requirements and morphology, while Lake Trout and resident Arctic Char often form multiple ecotypes in lakes, some with different feeding behaviors. Knowledge gaps regarding northern fish trophic ecology are highlighted, and in particular include riverine systems and winter foraging behavior. This review is intended to inform predictions regarding the impacts of climate change on fish tropic ecology and to guide future research.
