Effects of anthropogenic disturbance and climate on patterns of bat fly parasitism.
Environmental conditions, including anthropogenic disturbance, can significantly alter host and parasite communities. Yet, our current knowledge is based mainly on endoparasites, while ectoparasites remain little studied. We studied the indirect effects of anthropogenic disturbance (human population...

Environmental conditions, including anthropogenic disturbance, can significantly alter host and parasite communities.
