两栖动物在全球范围内受到威胁，但并非所有物种都受到不同威胁过程的平等影响。这对于壶菌真菌（Batrachochytrium dendroatidis）构成的威胁是正确的。我们编制了一个欧洲的数据集，以分析欧洲两栖动物的感染趋势。感染风险并非随机分布在欧洲各地的地理或分类上。在流行率不同的国家内，某些两栖动物类群的感染是非随机的。Rana属的棕色蛙不太可能被感染，而Alytidae和Bombinatoridae科的蛙被感染的可能性明显高于偶然预测。在欧洲开展壶菌病空间监测研究应以2科蛙为研究对象。理想情况下，对石斛属的调查应该通过对广泛分布的Pelophylax属进行采样来加强，因为该分类群对石斛属的过度感染在地理上不一致，对其进行监测可能有助于识别引起感染强度空间变异的因素。几个欧洲两栖动物类群在我们的数据集中没有表现出来；但是，在必要时也应对未取样的物种进行监测。
Amphibians are globally threatened, but not all species are affected equally by different threatening processes. This is true for the threat posed by the chytridiomycete fungus (Batrachochytrium dendrobatidis). We compiled a European data set for B. dendrobatidis to analyze the trends of infection in European amphibians. The risk of infection was not randomly distributed geographically or taxonomically across Europe. Within countries with different prevalence, infection was nonrandom in certain amphibian taxa. Brown frogs of the genus Rana were unlikely to be infected, whereas frogs in the families Alytidae and Bombinatoridae were significantly more likely to be infected than predicted by chance. Frogs in the 2 families susceptible to B. dendrobatidis should form the core of attempts to develop spatial surveillance studies of chytridiomycosis in Europe. Ideally, surveys for B. dendrobatidis should be augmented by sampling the widespread genus Pelophylax because this taxon exhibits geographically inconsistent overinfection with B. dendrobatidis and surveillance of it may facilitate recognition of factors causing spatial variability of infection intensity. Several European amphibian taxa were not represented in our data set; however, surveillance of unsampled species should also occur when warranted.
