With the rapid process of urbanization at a global scale, university campuses have been viewed as important urban green spaces for biodiversity conservation. However, little is known about the role of university campuses in protecting ecological specialists, the species usually vulnerable to anthropogenic disturbance. We assessed the associations between several ecological variates and ecological specialization of bird communities across 198 Chinese university campuses. A total of 398 bird species were recorded, including 109 diet specialist species and 104 foraging stratum specialist species. We found that the elevation of campuses was positively related to diet specialist species richness, and the campus area was positively related to foraging stratum specialist species richness. NDVI was positively associated with the community-wide foraging stratum specialization index, but negatively associated with the community-wide diet specialization index. Our results suggest that campuses with larger areas or located at high elevations play an important role in maintaining ecological specialization of bird communities.
在全球范围内城市化进程迅速的背景下，大学校园被视为城市生物多样性保护的重要绿色空间。然而，对于大学校园在保护生态特化物种（通常易受人为干扰的物种）方面的作用，我们了解甚少。我们评估了198个中国大学校园的几个生态变量与鸟类群落生态特化之间的关联。共记录到398种鸟类，包括109种食性特化物种和104种觅食阶层特化物种。我们发现，校园海拔与食性特化物种丰富度呈正相关，校园面积与觅食阶层特化物种丰富度呈正相关。归一化植被指数（NDVI）与群落水平的觅食阶层特化指数呈正相关，但与群落水平的食性特化指数呈负相关。我们的结果表明，面积较大或位于高海拔的校园在维持鸟类群落的生态特化方面发挥着重要作用。
