Identifying the biological mechanisms underlying seasonality in infection can enable better prediction and prevention of future infection peaks. A recent study by Daversa et al (2018) tracked Spiny Common Toads (Bufo spinosus) within and across annual cycles to assess seasonal variation in movement, body temperatures and infection from the fungal pathogen, Batrachochytrium dendrobatidis (Bd). Across annual cycles, toads did not consistently sustain infections but instead gained and lost infections from year to year. Radio-tracking data showed that infections were lost after breeding migrations and pronounced seasonal variation in toad body temperatures may be the reason. This study provides evidence of migratory recovery (i.e., loss of infection during migration) in a wild populations and may help explain differences in susceptibility to Bd.
