Internal cephalodia of Lobaria pulmonaria were examined in two British locations, one in western Scotland (Isle of Skye) and the other in England (Cumbria, Lake District), sites which were predicted to have contrasting levels of fixed nitrogen deposition. Cephalodia were found to occupy a small proportion of the total biomass averaging (<1%) in both areas. Modelled nitrogen deposition in the sites in Cumbria was 3–6 times higher than in the Skye sites but the cephalodium relative biomass was not significantly different. It is suggested that local climatic and topographic effects might have reduced the estimated rate of nitrogen deposition at the former sites.

对一些英国 Lobaria pulmonaria (L.) Hoffm 种群中头孢的丰度和生物量的估计及其与氮沉降的关系。

内头畸形肺叶草在两个英国地点进行了检查，一个在苏格兰西部（斯凯岛），另一个在英格兰（坎布里亚郡，湖区），预计这些地点的固定氮沉积水平存在差异。发现 Cephalodia 在这两个地区平均占总生物量的一小部分 (<1%)。坎布里亚地区的模拟氮沉降比斯凯地区高 3-6 倍，但头孢类相对生物量没有显着差异。有人认为，当地的气候和地形影响可能会降低先前地点的估计氮沉积速率。
