| diversity of warning signal and social interaction influences the evolution of imperfect mimicry. | mimicry, the resemblance of one species by another, is a complex phenomenon where the mimic (batesian mimicry) or the model and the mimic (mullerian mimicry) gain an advantage from this phenotypic convergence. despite the expectation that mimics should closely resemble their models, many mimetic species appear to be poor mimics. this is particularly apparent in some systems in which there are multiple available models. however, the influence of model pattern diversity on the evolution of mimetic ... | 2018 | 30151165 |
| new host records for amblyomma rotundatum (acari: ixodidae) from grussaí restinga, rio de janeiro, brazil. | amblyomma rotundatum koch is a parthenogenetic tick usually associated with reptiles and amphibians. however, relatively few studies on occurrences of ticks in wild reptile populations in brazil have been produced. the aim of this study was to analyze the presence of ticks associated with reptile species in the grussaí restinga, in the municipality of são joão da barra, state of rio de janeiro, brazil. between december 2010 and january 2011, 131 individuals belonging to nine species of reptiles ... | 2012 | 23070450 |
