Bell
et al have reported in
Ecohealth a high prevalence of
Bd from two national parks in Gabon, Monts de Cristal and Ivindo.
Bd was detected in 20 of the 42 species and was present at all three sites surveyed with high prevalence (19.6%–36.0%). Both national parks were
Bd-positive at all elevations and across habitat types, though no dead or dying frogs were encountered. This last observation is in keeping with those made in other regions of Africa, barring dieoffs reported from Kihansi and the Drakensburg. Bell
et al's report contrasts with those of Gratwick
et al who sampled other regions of Gabon: all were negative. Therefore, there appears to be a high degree of spatial heterogeneity in the prevalence of
Bd in Gabon which begs the question, Why?
