Full textBrazil has the highest number of parrot species in the world (about 74), 17 of them endangered. Among them is the hyacinth macaw (Anodorhynchus hyacinthinus), which is considered vulnerable and could become endangered in the near future, due to the intense illegal traffic and loss of habitat. In this study we estimated levels of variability and characterized the genetic structure of natural populations of hyacinth macaws. We analyzed 10 microsatellite loci from 98 individuals and concatenated sequences of mitochondrial genes (ND5, cytochrome b and ND2, 2,123 bp total) from 80 individuals. The genetic diversity index was low compared to those from other species of parrots. In addition, RST indeces and Bayesian analysis of microsatellite data showed moderate genetic structure among individuals of four regions in Brazil (north Pantanal, south Pantanal, north and northeast), but FST indeces indicate differentiation only between three regions (north and northeast without differentiation). This is in accordance with the strong genetic structure indicated by FST indeces and haplotype network based on mitochondrial sequences. Based on the mitochondrial data, the time of divergence of the genetic groups of hyacinth macaws was estimated to have occurred 16 to 42 thousand years ago, which corresponds to the late Pleistocene. Still, the results suggest that the population has been demographically stable over time, which may indicate that the low variability levels may be a characteristic of the species. However, the haplotype network presents a star shape, which indicate recent expansion, specially in the northeast. Additionally, given the population genetic structure data, it was possible to identify the most probable region of origin of apprehended individuals, this information is important to plan preventive and repressive control. Additionally, we analyzed seven microsatellite loci of chicks sampled in the same nest (same breeding season, alternate breeding seasons and consecutive seasons) in two regions of the Pantanal. The results suggest that the species is predominantly monogamous, but there is at least 12.5% of extra-pair paternity and 6.5% of brood parasitism. Furthermore, the genetic data is congruent with field observations that suggest that many couples return to the same nest in consecutive and alternative breeding seasons. Finally, we standardized for a molecular sexing protocol for molten feathers. In conclusion, the genetic results obtained in this study provide information about the processes involved in the evolutionary history and the reproductive behavior of hyacinth macaws that may help plan conservation actions.

Full textIn addition to environmental and demographic factors, the study of genetic properties of populations became inevitable issues in the conservation of declining populations. To acquire relevant information for conservation planning and implementing conservation strategies, conservationists have realized the need of population genetics tools. Moreover, this discipline has become more efficient with the development of a wide range of effective and relatively cheap methods for the characterization of a huge number of molecular markers. This led to define the conservation genetics as a separate discipline, which is the use of genetics in species preservation as dynamic entities evolving to cope with environmental changes and to minimize their extinction risk. Using a broad panel of molecular markers (mitochondrial and nuclear genes, microsatellites and SNPs), we interested in the evolutionary history at different spatial and temporal scales of the Mediterranean western subspecies Testudo hermanni hermanni (THH), which presents a very fragmented insular and continental distribution. The aim of this study is to 1) understand the processes that explain the current distribution of the structure and genetic diversity of populations, 2) identify the origin of introduced populations (Menorca and Ebro Delta) and 3) Dating the origin of the subspecies THH. At the population level, our study aimed to identify the number of homogeneous genetic groups of THH tortoise and the degree of genetic differentiation between these groups in order to identify evolutionarily significant units (ESU) and management units (MU). Finally, we were interested in the study of the last core populations of THH in the Var by landscape genetics approach. Our results revealed that a divergence by vicariance pattern explains the origin of the appearance of the subspecies THH. This biogeographic scenario is explained by the succession of glacial and interglacial events of the Pleistocene causing a withdrawal of the species toward refugia on the northern Mediterranean fringe. Moreover, the observed differentiation pattern (island vs continent) is very original compared to the reported diversity patterns of other reptiles sharing the same distribution range. According to our results, we may conclude that the Hermann’s tortoise is not native in Menorca and has a double origin: the first, is an introduction resulting from a unique source, probably from a continental lineage genetically close to Albera. The second, from an island origin, is the result of multiple contributions, from Corsica, Sardinia or Sicily. Lastly,the isolation of THH populations within each geographic region reflects a very strong genetic structure, therefor the six most relevant management units forconservation purposes are proposed on the basis that they represent a significant part of the evolutionary legacy of the species

Fagus hayatae Palib., a rare and statutory-conserved plant in Taiwan, is distributed in Chatienshan Nature Reserve, Tongshan area, and few new single mountain areas. It can also be found in Sichun province, Hubei province, and Zhejiang province in China. A population genetics research on this endangered species was conducted by using chloroplast trnL–F and rbcL–atpB regions; three microsatellite markers developed for Fagus crenata were also examined in Fagus hayatae on the nine populations in Taiwan and three populations in China. Results showed that a low variation in Taiwan''s populations using chloroplast markers, and a close relationship with the related taxa from China. Results also indicated a clear divergence of the populations from Syue Mountain (Beicha, Loupei, Lala, Niauzui, and Ayu) and Central Mountains (Lenkan, Dabai, Taipin Beech Trail, and Tongsan). By conducting microsatellite analysis, populations in Taiwan exhibited low level of genetic variation, while populations in China had higher level of genetic variation, especially for Zhejian’s population. Nevertheless, results of Bayesian clustering analysis suggested that populations in Taiwan and China should be considered as a single genetically distinct group. The results from microsatellite data provide more genetic information and therefore can be a great resource for further population genetics studies, hopefully provide applications to conservation biology of Fagus hayatae in Taiwan.
