| chromosome painting in neotropical long- and short-tailed parrots (aves, psittaciformes): phylogeny and proposal for a putative ancestral karyotype for tribe arini. | : most neotropical psittacidae have a diploid number of 2n = 70, and a dichotomy in chromosome patterns. long-tailed species have biarmed macrochromosomes, while short-tailed species have telo/acrocentric macrochromosomes. however, the use of chromosome painting has demonstrated that karyotype evolution in psittacidae includes a high number of inter/intrachromosomal rearrangements. to determine the phylogeny of long- and short-tailed species, and to propose a putative ancestral karyotype for thi ... | 2018 | 30309041 |
| novel nonsurgical approach to stabilization of bilateral pathologic femoral fractures in an egg-laying maroon-bellied conure (pyrrhura frontalis). | a 2-year-old, egg-laying maroon-bellied conure (pyrrhura frontalis) was referred for treatment of bilateral femoral fractures believed to be secondary to recent egg laying and nutritional and husbandry deficiencies. on radiographs, all skeletal components were diffusely osteopenic, precluding surgical fixation. a novel device to stabilize the bilateral femoral fractures was manufactured with polyvinyl chloride piping, which braced the bird's feet at the level of the perch and supported its upper ... | 2016 | 27315387 |
