D.; Kuabara, K. M. D.; Torre, G. M. de la; Ogrzewalska, M.; Martins, T. F.; Dutra, D. de AngeliNeotropical birds are mostly parasitized by immature ticks and act as reservoir hosts of tick-borne pathogens of medical and veterinary interest. Hence, determining the factors that enable ticks to encounter these highly mobile hosts and increase the potential for tick dispersal throughout migratory flyways are important for understanding tick-borne disease transmission. We used 9682 individual birds from 572 species surveyed across Brazil and Bayesian models to disentangle possible avian host traits and climatic drivers of infestation probabilities, accounting for avian host phylogenetic relationships and spatiotemporal factors that may influence tick prevalence. Our models revealed that the probability of an individual bird being infested with tick larvae and nymphs was lower in partial migrant hosts and during the wet season. Notably, infestation probability increased in areas with a higher proportion of partial migrant birds. Other avian ecological traits known to influence tick prevalence (foraging habitat and body mass) and environmental condition that might constrain tick abundance (annual precipitation and minimum temperature) did not explain infestation probability. Our findings suggest that migratory flyways harbouring a greater abundance of migrant bird hosts also harbour a higher prevalence of immature ticks with potential to enhance the local transmission of tick-borne pathogens and spread across regions.Item A new genus and new species of macronyssid mite (Mesostigmata: Gamasina: Macronyssidae) from Brazilian caves including molecular data and key for genera occurring in Brazil(2021-05-27) Gomes-Almeida, Brenda K.; Pepato, Almir R.A new genus and a new species of macronyssid mites is described based on material collected from caves in Minas Gerais state, Southeastern Brazil, and additional occurrences from caves in Rio de Janeiro (Southeast) and Pará (Eastern Amazon region). The new genus may be distinguished from other Macronyssidae genera by the combination of sternal shield with a distinct X-shaped area; sternal shield bearing three pairs of setae and two pairs of pores; sternal gland absent; anterior spur on coxa II lacking; adults with dorsal shield entire and j and J series complete; adults and protonymphs with setae J5 minute; males with strong-pores on dorsal shield and peritrema short extending from posterior margin of coxae II to the anterior margin of coxae IV. A key for genera occurring in Brazil is provided, as well sequences from the mitochondrial large subunit of ribosome (16S).Item New records of rare Ornithodoros (Acari: Argasidae) species in caves of the Brazilian Amazon(Persian Journal of Acarology, 2012) Simões, Matheus Henrique; Bernardi, Leopoldo Ferreira de Oliveira; Ogrzewalska, Maria; Labruna, Marcelo Bahia; Ferreira, Rodrigo LopesItem A new species of Neocarus Chamberlin & Mulaik, 1942 (Opilioacarida, Opilioacaridae) from Brazil, with remarks on its post larval development(ZooKeys, 2013) Bernardi, Leopoldo Ferreira de Oliveira; Klomplen, Hans; Zacarias, Mauricio Sergio; Ferreira, Rodrigo LopesItem Occurrences of Erythracarus nasutus Otto, 199(Anystoidea: Anystidae) in undergroud environments in Brazil(Espeleo -Tema, 2010) Bernardi, Leopoldo Ferreira de Oliveira; Mineiro, Jeferson Luiz de Carvalho; Silva, Marconi Souza; Ferreira, Rodrigo LopesItem Sampling effort in mite communities associated with cave bat guano(Speleobiology Notes, 2012) Pelegrinni, Thais Giovannini; Ferreira, Rodrigo LopesItem Snout mites from caves in Brazil, with description of a new species (Acari: Trombidiformes: Bdellidae)(Journal of Natural History, 2011) Hernandes, Fabio A.; Bernardi, Leopoldo Ferreira Oliveira; Ferreira, Rodrigo Lopes
