| host body size and the diversity of tick assemblages on neotropical vertebrates. | identifying the factors that influence the species diversity and distribution of ticks (acari: ixodida) across vertebrate host taxa is of fundamental ecological and medical importance. host body size is considered one of the most important determinants of tick abundance, with larger hosts having higher tick burdens. the species diversity of tick assemblages should also be greater on larger-bodied host species, but empirical studies testing this hypothesis are lacking. here, we evaluate this rela ... | 2016 | 27812506 |
| host specificity in a diverse neotropical tick community: an assessment using quantitative network analysis and host phylogeny. | host specificity is a fundamental determinant of tick population and pathogen transmission dynamics, and therefore has important implications for human health. tick host specificity is expected to be particularly high in the tropics, where communities of ticks, hosts and pathogens are most diverse. yet the degree to which tropical tick species are host-specific remains poorly understood. combining new field data with published records, we assessed the specificity of tick-host associations in pan ... | 2016 | 27357506 |
| amblyomma tapirellum (acari: ixodidae) collected from tropical forest canopy. | free-ranging ticks are widely known to be restricted to the ground level of vegetation. here, we document the capture of the tick species amblyomma tapirellum in light traps placed in the forest canopy of barro colorado island, central panama. a total of forty eight adults and three nymphs were removed from carbon dioxide-octenol baited cdc light traps suspended 20 meters above the ground during surveys for forest canopy mosquitoes. to our knowledge, this represents the first report of questing ... | 2013 | 25075277 |
| questing amblyomma mixtum and haemaphysalis juxtakochi (acari: ixodidae) infected with candidatus "rickettsia amblyommii" from the natural environment in panama canal basin, panama. | this work emphasizes the detection of candidatus "rickettsia amblyommii" in questing haemaphysalis juxtakochi and amblyomma mixtum. from february 2009 to december 2012, questing ticks were collected from the vegetation and leaf-litter of four protected forests and two grassy areas around the panama canal basin. dna was extracted from amblyomma mixtum, amblyomma naponense, amblyomma oblongoguttatum, amblyomma pecarium, amblyomma tapirellum, haemaphysalis juxtakochi, and unidentified immature ambl ... | 2015 | 26865823 |
