Resumen
BONIFAZ, Emilio y MENA, José Luis. Selective logging and host sex effects on the ectoparasitism of small mammals of the Southern Peruvian Amazon. Mastozool. neotrop. [online]. 2021, vol.28, n.1, pp.476-476. Epub 01-Dic-2020. ISSN 0327-9383.
Little is known about the effect of reduced impact logging on interspecific relationships, particularly the ectoparasite-host relationship. This study assessed the prevalence, abundance, and diversity of ectoparasites of small mammals in forests with reduced impact logging and control plots in southeastern Peruvian Amazon. We used Generalized Linear Models to assess the effect of reduced logging, habitat structure, and host sex on the ectoparasites of the most representative genera: Marmosops, Euryoryzomys, Proechimys, and Carollia. No statistical evidence about an effect of reduced logging on both the prevalence and diversity of ectoparasites were found. However, we found a positive effect of logging on the abundance of mites (Laelapidae) and ticks (Ixodidae) at individual level for Marmosops spp. and Proechimys spp. respectively; but a negative effect on mite abundance in Euryoryzomys spp. In addition, female rodents had a higher amount of ectoparasites. On the other hand, the intensity of the bat flies (Streblidae) in individuals of Carollia spp. was lower in logged forests. This study is one of the few to address the effect of reduced logging on ectoparasitism in small mammals. We suggest expanding the knowledge about the effects of these interactions to a specific level on a seasonal basis, which can provide further information to improve understanding of how this anthropogenic activity affects interactions between mammals and their ectoparasites.
