Resumen:
Vegetation type and seasonality promote changes in the species
composition and abundance of parasite hosts. However, it is poorly known
how these variables affect host-parasite interaction networks. This
information is important to understand the dynamics of parasite-host
relationships according to biotic and abiotic changes. We compared the
specialization of host-bat fly interaction networks, as well as bat fly
and host species composition between upland dry forest and riparian
forest and between dry and rainy seasons in a tropical dry forest in
Jalisco, Mexico. Bat flies were surveyed by direct collection from bats.
Our results showed that hostbat fly interaction networks were more
specialized in upland dry forest compared to riparian forest. Bat fly
species composition was different between the dry and rainy seasons,
while host species composition was different between upland dry forest
and riparian forest. The higher specialization in upland dry forest
could be related to the differences in bat host species composition and
their respective roosting habits. Variation in the composition of bat
fly species between dry and rainy seasons coincides with the seasonal
shifts in their species richness. Our study confirms the high
specialization of host-bat fly interactions and shows the importance of
biotic and abiotic factors to understand the dynamics of parasite-host
interactions.
