Data from: Known and estimated distribution in Mexico of Batrachochytrium dendrobatidis, a pathogenic fungus of amphibians

Chytridiomycosis caused by fungus Batrachochytrium dendrobatidis (Bd) is
one of decline global causes of amphibians. Currently is distributed
throughout a broad range of climates and ecosystems around the world. An
epidemic wave of chytridiomycosis began in North America, resulting in
population decline and local extinction of many species, reconfiguring
species composition of amphibian communities in the Americas. In Mexico,
Bd has caused an amphibian population decrease, and its potential
distribution area has not been determined. We reviewed the number of
species infected, obtaining Bd frequency of infection by land use and
vegetation type, and by elevation range. We examined the known
distribution of Bd, estimated the potential distribution, and obtained the
bioclimate variables relevant for Bd. Our results indicate that in Mexico,
Bd has been detected in 78 species of amphibians in 10 families, from 29
different land use and vegetation types, with cloud forest having the
highest number of cases (139) and infected species (15). Bd occurs over an
elevation range of 1–3,300 m asl, and is most frequent at 1,200–1,500 m
asl (36%). In addition to the regions previously described as suitable for
Bd, our model included desert, coastal and tropical forest regions,
revealing an increase in the area where amphibians could be at risk of
infection. Distribution of Bd is mainly associated with temperature of the
wettest quarter and potential evapotranspiration of the warmer quarter. We
offer an estimate of the ideal conditions for Bd in Mexico, also
information for future studies on Bd and the conservation of amphibians.
