2021年出现的17岁的Brood X蝉（Magicicada septendecim，M. cassinii和M. septendecula）看到数十亿只蝉从美国中西部和东部的土壤中出现。出现左连接的洞穴在表面可见，这是假设影响近地表水文过程。为了研究这些过程，我们使用单环，双头入渗仪测量田间饱和导水率（Kfs，n= 70）在美国中南部印第安纳州的出现和土地利用模式。我们的实验设计包括地点和没有洞穴在森林（未受干扰）和城市化（干扰）地区。在未受干扰的网站，我们发现一个显着的80.8%增加kfs之间的土壤（中位数= 14.1 cm/h;n= 20）和没有（中位数= 7.8 cm/h;n= 20）的潜穴。在受干扰的地点，我们发现Kfs没有显着差异之间的网站（中位数= 4.2厘米/小时，n= 18）和没有（中位数= 4.4厘米/小时，n= 12）的潜穴。我们发现，在未受干扰的地点，地表存在的洞穴数量与Kfsrate之间存在显著相关性（ρ$$ \rho $$ = 0.42;p =0.008），而在受干扰的地点没有发现相关性（ρ$$ \rho $$ =-0.09;p =0.62）。我们的测量结果表明，在城市化地区的洞穴onKfsis的影响最小化，可能是由于压实和人类干扰，减轻蝉留下的大孔的存在下的其他影响。相比之下，在未受干扰的地区，来自Brood X洞穴的表面连接的大孔隙作为降水进入土壤剖面的管道，并旁路流入更深的土层和浅层地下水位，对径流动态，土壤和地下水补给和质量以及养分循环产生影响。
The 2021 emergence of the 17‐year Brood X cicadas (Magicicada septendecim,M. cassinii, andM. septendecula) saw billions of cicadas emerge from the soil throughout the midwestern and eastern United States. The emergence left connected burrows visible at the surface, which are hypothesized to affect near surface hydrologic processes. To investigate these processes, we used single‐ring, dual head infiltrometers to measure field saturated hydraulic conductivity (Kfs,n= 70) across patterns of emergence and land use in south‐central Indiana, USA. Our experimental design included locations with and without cicada burrows in forested (undisturbed) and urbanized (disturbed) areas. Across undisturbed sites, we found a significant 80.8% increase inKfsbetween soils with (median = 14.1 cm/h;n= 20) and without (median = 7.8 cm/h;n= 20) cicada burrows. At disturbed sites, we found no significant difference inKfsbetween sites with (median = 4.2 cm/h;n= 18) and without (median = 4.4 cm/h;n= 12) cicada burrows. We found a significant correlation between the number of burrows present at the surface andKfsrates for undisturbed sites (ρ$$ \rho $$ = 0.42;p =0.008), while no correlation was found for the disturbed sites (ρ$$ \rho $$ = −0.09;p =0.62). Our measurements suggest that the effect of burrows onKfsis minimized in urbanized areas, potentially due to compaction and other impacts from human disturbance that mitigate the presence of macropores left by cicadas. In contrast, surface‐connected macroporosity from Brood X cicada burrows in undisturbed areas act as a conduit for precipitation into the soil profile and bypass flow into deeper horizons and the shallow groundwater table, with implications for runoff dynamics, soil and groundwater recharge and quality, and nutrient cycling.
