1.在考虑觅食资源时，决定蜜蜂群落结构的栖息地成分是众所周知的；然而，关于筑巢资源的作用的数据很少。作为一个模型系统，这项研究使用了地中海景观中21个不同的蜜蜂群落，其中包括火灾后再生的各种栖息地。这些发现清楚地表明，各种筑巢基质和筑巢材料在组织蜜蜂群落的组成中起着关键作用。裸地的可用性和潜在的筑巢空穴是影响整个蜜蜂群落结构、行会组成和优势种相对丰度的两个主要因素。其他重要的筑巢资源包括陡峭和倾斜的地面的可用性，提供精干的植物物种的丰富，以及先前存在的洞穴的出现。在火后更新的不同阶段，不同生境的巢资源可获得性和行会结构明显不同，但在所有情况下，巢地点和巢资源都是蜜蜂群落结构的重要决定因素。
1. The habitat components determining the structure of bee communities are well known when considering foraging resources; however, there is little data with respect to the role of nesting resources.2. As a model system this study uses 21 diverse bee communities in a Mediterranean landscape comprising a variety of habitats regenerating after fire. The findings clearly demonstrate that a variety of nesting substrates and nest building materials have key roles in organising the composition of bee communities.3. The availability of bare ground and potential nesting cavities were the two primary factors influencing the structure of the entire bee community, the composition of guilds, and also the relative abundance of the dominant species. Other nesting resources shown to be important include availability of steep and sloping ground, abundance of plant species providing pithy stems, and the occurrence of pre-existing burrows.4. Nesting resource availability and guild structure varied markedly across habitats in different stages of post-fire regeneration; however, in all cases, nest sites and nesting resources were important determinants of bee community structure.
