Ectoparasites of small mammals in a fragmented area of the southern Amazonia: interaction networks and correlations with seasonality and host sex.

摘要: The present work aimed to analyze the ectoparasite-host interaction network and possible differences of this related two seasonal periods host sex. During November 2016 July 2017, non-flying small mammals were captured in 17 forest fragments located southern portion Amazon biome. We 96 individuals belonging 10 species that parasitized with a total 3668 ectoparasites. Overall, we identified 24 ectoparasite taxa mite insect groups Ixodida (ticks), Mesostigmata, Sarcoptiformes, Trombidiformes (mites), Phthiraptera (lice), Siphonaptera (fleas). between all ectoparasites hosts showed significant deviation from random, moderately high specialization index (H2' = 0.80). There was difference prevalence for Amblyomma cajennense (Fabricius) sensu stricto (s.s), coelebs Neumann larvae Amblyomma. This also found mean intensity infestation Tur aragaoi (Fonseca). Only differed relation sex Marmosa constantiae Thomas. Our results demonstrate specificity region is pattern aggregation some seasons, as well sexes M. constantiae.
