在充满空气的洞穴和喀斯特栖息地中，穴居动物和嗜穴居动物依靠湿润的洞穴壁面上的水滴或片流的外来（来自表面的）有机质的流入。这种生境类型被称为洞穴湿性（Sket, 2004）。一些洞穴吸湿生境的水文隔离可能会限制有机物的流入，使生境总体上受到营养限制。因此，长时间的食物限制已成为穴居动物进化适应的主要驱动力（例如，Sket, 2004）。在意大利东北部Grotta della Foos，一种高度进化的穴居甲虫Cansiliella servadeii Paoletti 1980（鞘翅目：Leptodirini，前身为深海甲虫科）被发现于地表以下约450米的深度。Paoletti M.G, Beggio M, Dreon A.L, Pamio A, Gomiero T., Brilli M., Dorigo L., Concheri G., Squartini A., Summers Engel A. 2011。基于钙质洞穴中微生物的新食物网：意大利北部的卡西里拉（甲虫）案例。国际洞穴学杂志，40(1),45-52。佛罗里达州坦帕市（美国）。ISSN 0392 - 6672。1827 - 806 - x.40.1.6 DOI: 10.5038 /
inTrOducTiOn In air-filled cave and karst habitats, troglobites and troglophiles rely on an influx of allochthonous (surface-derived) organic matter from dripwaters or sheetflow on moist cave-wall surfaces. This habitat type is referred to as the cave hygropetric (Sket, 2004). Hydrological isolation for some cave hygropetric habitats may restrict the influx of organic matter, making a habitat nutrient-limited overall. Consequently, food limitation over extended periods of time has served as a major driver for evolutionary adaptation for troglobites (e.g., Sket, 2004). One highly evolved, troglobitic beetle, Cansiliella servadeii Paoletti 1980 (Coleoptera: Leptodirini, formerly Bathysciinae), has been found at a depth of ~450 m below the surface in Grotta della Foos, northeastern Italy.
