- Infection patterns of the chytrid fungus, Batrachochytrium dendrobatidis, on anuran assemblages in agro-ecosystems from Buenos Aires Province, Argentina. The disease chytridiomycosis, caused by the pathogenic chytrid fungus Batrachochytrium dendrobatidis (Bd), is linked to extinctions and declines of amphibians. Additionally, in the context of amphibian decline, the habitat loss related to agricultural landscapes is likely the single most important human activity affecting lowland amphibian populations. To assess the impact of anthropogenic land use on anuran response to Bd, infection patterns in several ponds from cultivated (CA) and uncultivated areas (UCA) were studied. Four anuran species (Rhinella fernandezae [Bufonidae]; juvenile and adult of Leptodactylus latrans [Leptodactylidae]; and the hylids Hypsiboas pulchellus and Pseudis minuta) were monitored and tissue samples were collected for Bd diagnosis and quantification. All species tested positive for Bd, but anurans inhabiting the UCA were twice more likely to be infected than those in the CA. Prevalence and infection level were significantly higher in the UCA, suggesting that vulnerability to Bd is associated with land use in agroecosystems. At the assemblage-level, the infection patterns also differed among species, and those with aquatic habitats (L. latrans and P. minuta) had high prevalence and infection levels of Bd. Juvenile stages of L. latrans had higher prevalence and infection level than adults in both study areas. This work contributes to our understanding of anthropogenic effects on host-pathogen relationships, particularly on the effect of Bd on anuran assemblages under different levels of agricultural impact.
A quitridiomicose, causada pelo fungo quitrídeo patogênico Batrachochytrium dendrobatidis (Bd), está ligada a extinções e declínios de anfíbios. Adicionalmente, no contexto dos declínios de anfíbios, a perda de habitat relacionada às paisagens agrícolas é provavelmente a atividade humana isolada mais importante que afeta populações de anfíbios de planícies. Para avaliar o impacto do uso antropogênico da terra sobre a resposta dos anuros ao Bd, foram estudados os padrões de infecção em diversas lagoas de áreas cultivadas (CA) e incultas (UCA). Quatro espécies de anuros (Rhinella fernandezae [Bufonidae]; juvenis e adultos de Leptodactylus latrans [Leptodactylidae]; e os hilídeos Hypsiboas pulchellus e Pseudis minuta) foram monitoradas e amostras de tecido foram coletadas para diagnose G SWCPVKsECÁºQ FQ Bd. Todas as espécies mostraram-se infectadas pelo Bd, mas os anuros de UCA tiveram probabilidade duas vezes maior de estar infectadas do que aquelas de CA. A prevalência e o nível de infecção foram significativamente maiores nas UCA, sugerindo que a vulnerabilidade ao Bd está associada ao uso da terra em agro-ecossistemas. No nível de assembleias, os padrões de infecção também diferiram entre as espécies, e aquelas de habitats aquáticos (L. latrans and P. minuta) tiveram alta prevalência e altos níveis de infecção de Bd. Os estágios juvenis de L. latrans tiveram maior prevalência e maior nível de infecção do que os adultos em ambas as áreas de estudo. Este trabalho contribui para o conhecimento dos efeitos antropogênicos sobre as relações hospedeiro-patógeno, particularmente sobre o efeito do Bd em assembleias de anuros sujeitas a diferentes níveis de impacto agrícola.
