| ecological relationships of meso-scale distribution in 25 neotropical vertebrate species. | vertebrates are a vital ecological component of amazon forest biodiversity. although vertebrates are a functionally important part of various ecosystem services they continue to be threatened by anthropogenic impacts throughout the amazon. here we use a standardized, regularly spaced arrangement of camera traps within 25km2 to provide a baseline assessment of vertebrate species diversity in a sustainable use protected area in the eastern brazilian amazon. we examined seasonal differences in the ... | 2015 | 25938582 |
| isolation and characterization of ten novel microsatellite loci in the red-winged tinamou (rhynchotus rufescens, tinamiformes, aves) and cross-amplification in other tinamous. | we describe the isolation and characterization of ten microsatellite loci from the red-winged tinamou (rhynchotus rufescens) and also evaluated the cross-amplification of these loci and other ten loci previously developed for the great tinamou (tinamus major) in other tinamous. genetic variability was assessed using 24 individuals. six loci were polymorphic with moderate to high number of alleles per locus (2-12 alleles) and showed expected heterozygosity (he) ranging from 0.267 to 0.860. all lo ... | 2012 | 21947952 |
| the complete mitochondrial genome of the white-throated tinamou, tinamus guttatus (tinamiformes, tinamidae). | the white-throated tinamou, tinamus guttatus (tinamiformes, tinamidae) is a species of the family tinamidae. herein, we firstly reported the complete mitochondrial genome of white-throated tinamou. the length of mitogenome was 16 750 bp, and composed of 13 protein-coding genes, 22 trna genes, 2 rrna genes, and 1 putative misc-feature region. most protein-coding genes started with a traditional atg codon, but specially, cox1 and cox2 initiated with an infrequent start codon gtg instead, nd3 and n ... | 2016 | 26195216 |
| a nanostructural basis for gloss of avian eggshells. | the role of pigments in generating the colour and maculation of birds' eggs is well characterized, whereas the effects of the eggshell's nanostructure on the visual appearance of eggs are little studied. here, we examined the nanostructural basis of glossiness of tinamou eggs. tinamou eggs are well known for their glossy appearance, but the underlying mechanism responsible for this optical effect is unclear. using experimental manipulations in conjunction with angle-resolved spectrophotometry, s ... | 2015 | 25505139 |
| focal philophthalmus gralli infection possibly persists in melanoides tuberculata over two years following the definitive hosts' removal. | philophthalmosis is a zoonotic disease associated largely with the spread of the invasive freshwater snail melanoides tuberculata, serving as an intermediate host. here we examined philophthalmus gralli focal fenced infection site reported recently as being associated with tinamus major and m. tuberculata in alajuela, costa rica. removal of the definitive hosts allowed us to address also the long-term survival strategy of the parasite. initially, the snail intermediate hosts displayed high preva ... | 2014 | 25102356 |
| pathology and first report of natural eye infection with the trematode philophthalmus gralli (digenea, philophthalmidae) in tinamus major (tinamiformes, tinamidae), costa rica. | the eye-fluke philophthalmus gralli (philophthalmidae looss, 1899) was found in six birds known as great tinamous (tinamus major) reared in a wild animal shelter located in alajuela, costa rica. the birds presented conjunctival hyperemia, blepharitis, anorexia and weakness. some of them suffered from unilateral blindness and ocular loss. after morphometric analysis, the specimens showed characteristics compatible with the digenean trematode p. gralli. the clinical signs of infection were resolve ... | 2013 | 23993998 |
| development of microsatellite markers for parentage analysis in the great tinamou (tinamus major). | eighteen microsatellite loci were isolated from great tinamous (tinamus major), which are large terrestrial birds found in the neotropics. these are the first primers developed for the order tinamiformes. paternity analyses are possible because the levels of heterozygosity are sufficiently high (0.29-0.90). | 2008 | 21585934 |
