DNA sampling from eggshells and microsatellite genotyping in rare tropical birds: Case study on Brazilian Merganser
This study shows that sampling maternal DNA from hatched and abandoned eggshells is a viable noninvasive strategy for studying the genetics of rare or endangered tropical birds, as exemplified here by the Brazilian Merganser (Mergus octosetaceus). Eighteen microsatellites were isolated from enriched libraries and nine heterologous loci from related species were tested. Seven loci were amplified...
متن کاملBlood parasites in passerine birds from the Brazilian Atlantic Forest.
Parasites may lead bird species to extinction, affect host temporal and spatial population dynamics, alter community structure and alter individual' social status. We evaluated blood parasite prevalence and intensity according to bird families and species, among 925 birds that were caught in 2000 and 2001, in the Atlantic Forest in the State of Minas Gerais, Brazil. We applied Giemsa staining t...
متن کاملSex determination in birds: HINTs from the W sex chromosome?
Sex in birds is controlled genetically (ZZ male: ZW female), but the genetic mechanism remains unclear. While some evidence points to the involvement of Z sex chromosome dosage, other data favour a dominant female-determining gene carried on the W sex chromosome. An intriguing candidate gene located on the chicken W chromosome is HINTW, which encodes an aberrant form of a hydrolase enzyme. In c...
متن کامل[Correlates of smoking in pregnant women in six Brazilian cities].
OBJECTIVE To evaluate sociodemographic and lifestyle correlates of smoking in pregnant women sampled from hospitals. METHODS A cross-sectional study was conducted in 5,539 pregnant women aged 20 or more who sought medical attention in prenatal clinics of affiliate hospitals of the Brazilian National Health System in the cities of Manaus, Fortaleza, Salvador, Rio de Janeiro, São Paulo, and Por...
متن کاملNovel Insights into Chromosome Evolution in Birds, Archosaurs, and Reptiles
Homologous synteny blocks (HSBs) and evolutionary breakpoint regions (EBRs) in mammalian chromosomes are enriched for distinct DNA features, contributing to distinct phenotypes. To reveal HSB and EBR roles in avian evolution, we performed a sequence-based comparison of 21 avian and 5 outgroup species using recently sequenced genomes across the avian family tree and a newly-developed algorithm. ...
