The illegal wildlife trade is one of the major threats to Brazil’s biodiversity. Approximately 80 % of illegally captured animals are birds, and 4 % of those are parrots. Although many seized birds do not survive, those that are recovered may be returned to the wild. The release of seized individuals into the wild should be conducted with caution, as local populations may suffer adverse effects if genetically different individuals are introduced. In this study, we evaluated the genetic… 
Population Genetic Structure in Hyacinth Macaws (Anodorhynchus hyacinthinus) and Identification of the Probable Origin of Confiscated Individuals.
Given the genetic structure observed, the most probable regions of origin of 24 confiscated individuals were identified, and these data helped to trace illegal traffic routes and identify natural populations that are being illegally harvested.
Genetic assignment and monitoring of yellow cardinals
A robust genetic assignment technique is contributed to be used in future yellow cardinal seizures and identify factors that might improve subsequent releases.
Effective Characterisation of the Complete Orang-Utan Mitochondrial DNA Control Region, in the Face of Persistent Focus in Many Taxa on Shorter Hypervariable Regions
The number, length and position of hypervariable regions is inconsistent between orang-utan species, and that prior definitions of the HVRI were haphazard, highlighting the forensic utility of complete control-region sequences.
Genetic Assignment Tests to Identify the Probable Geographic Origin of a Captive Specimen of Military Macaw (Ara militaris) in Mexico: Implications for Conservation
It is shown that the use of genetic markers provides a promising tool for determining the origin of pets and individuals seized from the illegal animal trade to better inform decisions on reintroduction and improve conservation programs.

Back home? Uncertainties for returning seized animals to the source‐areas under climate change
The results suggest that population restoration programs for seized species need to be rethought, and furthermore other suitable areas could be considered for truly ensuring the survival and maintenance of overexploited populations in the long-term.
Use of swab for DNA sampling from confiscated raptors for molecular sexing
The potential used of buccal swabs for genetics studies of raptor, with further optimization for a better result suggests the potential of swab to collect tracheal and cloacal epithelial cells of confiscated raptor bird for genetic studies.
Literature review of the use of birds as pets in Latin-America, with a detailed perspective on Mexico
A large amount of birds are harvested from the natural environment for the pet market. This trade is a conservation issue and an economic income for many people, two aspects not analyzed yet as a
El objetivo de este estudio fue describir los parametros hematologicos en 69 polluelos en cautiverio de origen silvestre, clinicamente sanos, menores de tres meses de edad, en cuatro especies de


Contrasting Phylogeographic Patterns in Mitochondrial DNA and Microsatellites: Evidence of Female Philopatry and Male-Biased Gene Flow Among Regional Populations of the Blue-and-Yellow Macaw (Psittaciformes: Ara ararauna) in Brazil
Analyses of population genetic structure based on mtDNA showed evidence of two major populations in western and eastern Brazil that share a few lowfrequency haplotypes, and male-biased dispersal and female philopatry best explain the different patterns observed in these two markers.
Detecting Wildlife Poaching: Identifying the Origin of Individuals with Bayesian Assignment Tests and Multilocus Genotypes
Evaluating the usefulness of two assignment tests to wildlife forensics by applying them to large empirical (microsatellite DNA) data sets from 10 species suggests that nearly all individuals can be assigned with high statistical certainty for two highly differentiated populations.
Wildlife DNA forensics—bridging the gap between conservation genetics and law enforcement
The requirement for wildlife DNA forensic analysis to be performed under equivalent qual- ity assurance standards to those of human forensic genetics is highlighted and approaches for the interpretation and presentation of DNA evidence are described.
Predicting the Probability of Outbreeding Depression
An extended form of the breeders' equation was used to predict the probability of OD due to adaptive differentiation between recently isolated population fragments as a function of intensity of selection, genetic diversity, effective population sizes, and generations of isolation.
The one that did not get away: individual assignment using microsatellite data detects a case of fishing competition fraud
Individual assignment based on microsatellite data was used to identify a case of fishing competition fraud and the usefulness of confidently excluding populations as the origin of an individual is emphasized.
Measuring and interpreting genetic structure to minimize the genetic risks of translocations
The fundamental inadequacy of using measures of genetic divergence to predict interactions between populations is illustrated, and there is no substitute for direct tests for variation in ecologically relevant traits and possible genetic incompatibilities among populations.
Between a rock and a hard place: evaluating the relative risks of inbreeding and outbreeding for conservation and management
Managers can minimize the risks of both inbreeding and outbreeding by using intentional hybridization only for populations clearly suffering from inbreeding depression, maximizing the genetic and adaptive similarity between populations, and testing the effects of hybridization for at least two generations whenever possible.
International wildlife trade : a CITES sourcebook
For more than two decades, the Convention on International Trade in Endangered Species of Wild Fauna and Flora, known as CITES, has been one of the largest and most effective conservation agreements
