ultraviolet reflectance structures of peacock feathers. | male peacock (pavo cristatus) tail feathers have an eyespot pattern with an inconspicuous black or dark blue center surrounded by brilliant, structural colors, such as blue, light brown, and yellow-green. under ultraviolet a (uva), the central part of the eyespot reflects uva better than the surrounding parts. herein, i examined various areas of eyespots on paraffin sections of feathers using an optical microscope, and characterized positional relationships between barbs and barbules. these anal ... | 2018 | 30298782 |
incidences of mortality of indian peafowl pavo cristatus due to pesticide poisoning in india and accumulation pattern of chlorinated pesticides in tissues of the same species collected from ahmedabad and coimbatore. | incidences of mortality of indian peafowl pavo cristatus, the national bird (schedule i indian wild life protection act 1972), are rampant in india. between january 2011 and march 2017, around 550 peafowl in 35 incidences were reported dead across the country. due to the non-availability of fresh carcases, poisoning could not be confirmed. birds which died due to kite string injuries in ahmedabad (15) and accidents in coimbatore (5) were tested for residues of chlorinated pesticides, namely hexa ... | 2018 | 29569206 |
captivity stress influences the dna damage of pavo cristatus under environmental conditions of faisalabad, pakistan. | the surroundings of wild and captive birds are divergent in existence. wild birds inhabiting their natural environment have unlimited resources availability. they face variety of captivity stresses when moved from wild habitat to caged enclosures. the effect of similar captivity stresses on the dna of birds living in cages for longer stretches of time is addressed in this study. the laboratory analysis to investigate dna damage in pavo cristatus was performed using single-cell gel electrophoresi ... | 2020 | 31845253 |
hearing in indian peafowl (pavo cristatus): sensitivity to infrasound. | despite the excitement that followed the report of infrasound sensitivity in pigeons 40 years ago, there has been limited followup, with only eleven species of birds having auditory thresholds at frequencies below 250 hz. with such sparse data on low-frequency hearing, there is little understanding of why some birds hear very low frequencies while others do not. to begin to expand the phylogenetic and ecological sample of low-frequency hearing in birds, we determined the behavioral audiogram of ... | 2020 | 33025058 |
comparative analyses of coproscopical techniques to diagnose enteroparasites in a group of captive indian peafowl (pavo cristatus). | captive animals commonly have infections by direct life cycle parasites, since they are easily transmitted between individuals. however, diagnosing these infections in the laboratory is challenging due to the wide variety of parasite, their life stages and to the variety of available diagnose techniques, being difficult to choose the best one. the present study sampled a group of captive indian peafowl (pavo cristatus) from são paulo zoological park foundation, são paulo, brazil, to test and com ... | 2020 | 33128866 |
