Since host and parasite diversities are strongly connected, 13 landscape changes are also likely to change wildlife parasite diversity with implication for 14 wildlife health. However, research linking anthropogenic landscape change and wildlife 15 parasite diversity is limited, especially comparing effects of land use change and habitat 16 fragmentation, which often cooccur but may affect parasite diversity substantially 17 differently. Here, we assessed how anthropogenic land use change (presence of plantation, 18 livestock foraging and human settlement) and habitat fragmentation may change the 19 gastrointestinal parasite diversity of wild mammalian host species (n=23) in Anamalai hills, 20 India. We found that presence of plantations, and potentially livestock, significantly 21 increased parasite diversity due possibly to spillover of parasites from livestock to wildlife. 22 However, effect of habitat fragmentation on parasite diversity was not significant.
