| new quill mites of the family syringophilidae (acari: cheyletoidea). | five new species and two new genera belonging to the family syringophilidae (acari: cheyletoidea) are described from birds that died in the antwerp zoo during their quarantine: charadriaulobia vanelli n. g., n. sp. from vanellus chilensis (charadriiformes: charadriidae) in brazil; fritschisyringophilus lonchurae n. g., n. sp. from lonchura punctulata (passeriformes: estrildidae) in india; mironovia coturnae n. sp. from coturnix coturnix (galliformes: phasianidae) in europe; syringophiloidus dabe ... | 2004 | 14755175 |
| ticks on birds caught on the campus of the federal rural university of rio de janeiro, brazil. | the prevalence of parasitic infections, particularly those caused by ectoparasites, may influence the biology and ecology of wild birds. the aim of this study was to investigate occurrences and identify the species of ticks collected from wild birds caught on the campus of the federal rural university of rio de janeiro. the birds were caught using mist nets between october 2009 and december 2010. in total, 223 birds were caught, represented by 53 species and 19 families in nine orders. nineteen ... | 2012 | 23070429 |
| chromosome painting in vanellus chilensis: detection of a fusion common to clade charadrii (charadriiformes). | the southern lapwing (vanellus chilensis) is endemic to america and is well-known because of the vast expansion of its geographical distribution and its involvement in air accidents. despite its popularity, there is no information concerning the genomic organization and karyotype of this species. hence, because other species of the genus vanellus have variable diploid numbers from 2n = 58 to 76, the aim of this report was to analyze the karyotype of v. chilensis by means of classical and molecul ... | 2015 | 26088018 |
| predation-risk effects of predator identity on the foraging behaviors of frugivorous bats. | predators directly and indirectly affect the density and the behavior of prey. these effects may potentially cascade down to lower trophic levels. in this study, we tested the effects of predator calls (playbacks of bird vocalizations: tyto alba, speotyto cunicularia, and vanellus chilensis), predator visual stimuli (stuffed birds) and interactions of visual and auditory cues, on the behavior of frugivore phyllostomid bats in the field. in addition, we tested if the effects of predation risk cas ... | 2013 | 23657559 |
| automated sound recognition provides insights into the behavioral ecology of a tropical bird. | computer-assisted species recognition facilitates the analysis of relevant biological information in continuous audio recordings. in the present study, we assess the suitability of this approach for determining distinct life-cycle phases of the southern lapwing vanellus chilensis lampronotus based on adult vocal activity. for this purpose we use passive 14-min and 30-min soundscape recordings (n = 33 201) collected in 24/7 mode between november 2012 and october 2013 in brazil's pantanal wetlands ... | 2017 | 28085893 |
| novel insights into chromosome evolution of charadriiformes: extensive genomic reshuffling in the wattled jacana (jacana jacana, charadriiformes, jacanidae). | the order charadriiformes comprises three major clades: lari and scolopaci as sister group to charadrii. until now, only three charadriiformes species have been studied by chromosome painting: larus argentatus (lari), burhinus oedicnemus and vanellus chilensis (charadrii). hence, there is a lack of information concerning the third clade, scolapaci. based on this, and to gain a better understanding of karyotype evolution in the order charadriiformes, we applied conventional and molecular cytogene ... | 2020 | 32105288 |
| burrowing owls eavesdrop on southern lapwings' alarm calls to enhance their antipredatory behaviour. | eavesdropping is a widespread behaviour among animals, providing the receiver with valuable information to assess the habitat, resources or threats. this kind of behaviour has been reported for the burrowing owl (athene cunicularia), which in its northern range lives in close association with fossorial mammals and eavesdrops on their alarm calls as indicators of risk. in their southernmost range, burrowing owls do not associate with mammals, but they are often found sharing foraging and nesting ... | 2018 | 30308234 |
