In the context of global insect decline, the urbanisation process plays a key role. However, urban pavements, which are considered to be impervious to biodiversity, can harbour ground-nesting insects under certain conditions. Recent observations have revealed the presence of Formicidae nests under urban pavements. The aim of this work is to determine the species richness of Formicidae nesting under urban pavements in the Brussels-Capital Region (Belgium) and to characterise their nest environment and soil texture. Seven ant species were identified in 120 nesting sites: , , , , , and . Concrete slabs or natural stones with a sandy sub-layer are the main structures in which ants nest. In addition, nests were mainly found under modular pavements with degraded rigid joints. The results of this work highlight the capacity of urban structures to host part of ant biodiversity in cities.
在全球昆虫数量下降的背景下，城市化进程起着关键作用。然而，城市人行道被认为对生物多样性具有不可渗透性，但在某些条件下可能会有地面筑巢昆虫栖息。最近的观察发现城市人行道下存在蚁科巢穴。这项工作的目的是确定比利时布鲁塞尔首都大区城市人行道下筑巢的蚁科物种丰富度，并描述它们的巢穴环境和土壤质地。在120个筑巢地点鉴定出了7种蚂蚁： 、 、 、 、 、 和 。带有沙质下层的混凝土板或天然石块是蚂蚁筑巢的主要结构。此外，巢穴主要发现于刚性接缝退化的模块化人行道下方。这项工作的结果凸显了城市结构承载城市部分蚂蚁生物多样性的能力。
