Subfossil chironomid (Diptera, Chironomidae) remains are often used as indicators of lake level changes in palaeolimnological studies. However, their usefulness as a water depth proxy can vary between the sites, depending on the lake morphology, mode of taphonomic processes or amplitude of past water level fluctuations, among other factors. In this study, we have examined the distribution of subfossil chironomids in the shallow Lake Spore (northern Poland) to assess the influence of water depth on the fauna. Our aim was to evaluate the sitespecific utility of subfossil chironomids for lake level reconstruction at Lake Spore. The subfossil chironomid assemblages in Lake Spore have heterogeneous distribution, suggesting they are predominately composed of remains deposited close to the sampling location. A strong relationship between the water depth and the chironomids is marked by the 25.12% variance explained by water depth in the taxonomic data. Moreover, according to generalized linear models (GLMs) out of 44 dominant taxa, 12 have significant relationships with water Ac c ted A rtic l

亚化石摇蚊科（双翅目、摇蚊科）在波兰北部孢子湖浅水区沿水深梯度分布

亚化石摇蚊（双翅目，摇蚊科）遗骸经常被用作古湖泊学研究中湖泊水位变化的指标。然而，它们作为水深代理的有用性在不同地点可能有所不同，这取决于湖泊形态、埋藏过程的模式或过去水位波动的幅度等因素。在这项研究中，我们检查了浅层孢子湖（波兰北部）中亚化石摇蚊的分布，以评估水深对动物群的影响。我们的目的是评估亚化石摇蚊在孢子湖的湖面重建中的特定地点效用。孢子湖中的亚化石摇蚊组合具有异质性分布，表明它们主要由沉积在采样位置附近的遗骸组成。水深与摇蚊之间的密切关系以分类数据中水深解释的 25.12% 方差为标志。此外，根据广义线性模型 (GLM)，在 44 个优势类群中，有 12 个与水吸收类群有显着关系
