Helminths from Rodents in the Galapagos
In this first report of endoparasites from endemic mammals of the Galápagos islands, we identify a new species of cestode of the genus Raillietina (Cyclophyllidea: Davaineidae) from species of Nesoryzomys and summarize the extent of helminth parasitism in both Oryzomyine endemics and introduced spec...
