Abstract [en]

The chytrid fungus Batrachochytrium dendrobatidis (Bd), is a generalist pathogen which has caused amphibian population declines worldwide. In many species Bd infection causes the disease chytridiomycosis, leading to high mortality. However, infection may cause sub-lethal fitness effects even in species that are resistant or tolerant to Bd. Moreover, populations of the same species may differ in their sensitivity to Bd, but the factors behind this variation are poorly understood. Here we exposed two common North European amphibians (moor frog Rana arvalis, common toad Bufo bufo) from two latitudinally divergent regions to two different BdGPL strains in a laboratory experiment. We found that Bd exposure lowered survival in both species, but this effect was much stronger in B. bufo.  Moreover, survival was lower in the northern region in both species, this difference again being much stronger in B. bufo. Northern individuals were smaller in both species and the survival difference between regions was size mediated with smaller individuals being more sensitive to Bd. We discuss potential additional factors contributing to this result. Bd exposure also led to sub-lethal effects in terms of reduced growth in both species suggesting that even individuals surviving the infection may have reduced fitness mediated by reduction if body size. However, we did not detect any differences in amphibian responses to the two Bd strains.
