Outside of pest control reports, little attention has been paid to interior ecosystems in high-latitude regions. Opportunistic sampling of live arthropods captured inside the University of Alaska Museum Fairbanks, Alaska, United States of America allowed us to describe and analyse one such interior ecosystem. We document a minimum of 77 arthropod species over 18 years. Beetles, spiders, and booklice represented 80% of the total abundance. Of those captured, synanthropes consisted primarily of fungivores and detritivores, seasonals consisted primarily of predators and omnivores, and transients consisted primarily of predators and had greater diet and species diversity than the synanthropes and transients. January was the most common month for capturing synanthropes, September for capturing seasonals, and July for capturing transients. Four synanthropic species not previously known from Alaska, which appear to have breeding populations inside the museum, were found: Dorypteryx domestica (Smithers, 1958) (Psocodea: Psyllipsocidae), Cartodere constricta (Gyllenhal, 1827), Dienerella filum (Aubé, 1850), and Corticaria serrata (Paykull 1800) (Coleoptera: Latridiidae). Three transient and one synanthrope species previously unreported from Alaska, with no evidence of breeding populations, were also found: the click beetle Danosoma obtectum (Say, 1839) (Coleoptera: Elateridae), a spider in the genus Phantyna, probably the species P. bicornis (Emerton, 1915) (Araneae: Dictynidae), two Colobopsis sp. ant specimens (Hymenoptera: Formicidae), and the synanthropic spider Oecobius cellariorum (Dugès, 1836) (Araneae: Oecobiidae).

除害虫控制报告外，高纬度地区对内部生态系统的关注很少。在美国阿拉斯加费尔班克斯市阿拉斯加大学博物馆内捕获的活节肢动物的机会性抽样，使我们能够描述和分析这样一种内部生态系统。我们记录了18年中至少有77种节肢动物物种。甲虫，蜘蛛和书虱占总数的80％。在被捕获的那些中，拟人生物主要由真菌和碎屑动物组成，季节主要由食肉动物和杂食动物组成，而过渡性动物主要由食肉动物组成，并且饮食和物种多样性都比拟人动物和过渡动物更大。1月是捕获共生动物的最常见月份，9月是捕获季节性的，7月是捕获瞬态的。家蝇（Smithers，1958）（Psocodea：Psyllipsocidae），Cart虫（Codedere constricta）（Gyllenhal，1827），Dienerella filum（Aubé，1850）和Corticaria serrata（Paykull 1800）（Coleoptera：Latridiidae）。还发现了三个以前从未在阿拉斯加报道的过渡物种和一个同时物种，但没有繁殖种群的证据：:甲虫Danosoma obtectum（Say，1839）（鞘翅目：Elateridae），Phantyna属中的蜘蛛，可能是P。 bicornis（Emerton，1915年）（Araneae：Dictynidae），两个Colobopsis sp.。蚂蚁标本（膜翅目：昆虫纲）和同生蜘蛛Oecobius cellariorum （Dugès，1836年）（Araneae：Oecobiidae）。
