The tuco-tuco das dunas (Ctenomys flamarioni) is a subterranean rodent endemic to sand-dune ecosystems along the southern coast of Brazil. We studied 3 populations that differed in degree human impact, and used direct indirect methods assess demographic genetic information. Field studies revealed tendency toward female-biased sex ratio, sexual dimorphism both weight length all populations. This evidence supports hypothesis polygyny C. flamarioni. Using 9 microsatellite loci, we explored...
With about 68 recognized living species, subterranean rodents of the genus Ctenomys are found in a multiplicity habitats, from dunes Atlantic coast to Andes Mountains, including environments ranging humid steppes Pampas dry deserts Chaco region. However, this needs an exhaustive reevaluation its systematic and phylogenetic relationships regarding different groups that compose it. This knowledge is essential propose biodiversity conservation strategies both at species level higher...
Black-and-gold howler monkeys Alouatta caraya, are arboreal primates, inhabitants of Neotropical forests, highly susceptible to the yellow fever virus, considered early 'sentinels' outbreaks, and thus, major epidemiological importance. Currently, anthropogenic habitat loss modifications threatens their survival. Habitat modification can prevent, reduce or change dispersal behavior, which, in turn, may influence patterns gene flow. We explored past contemporary levels genetic diversity,...
The genetic variability for a sample of 227 animals from three populations Pantaneiro horses was estimated using data 10 microsatellite loci.The number alleles and the proportion heterozygosity indicated high variability.A total 91 were found, with significantly mean alleles.The polymorphic information content 0.7 paternity exclusion probability 99.3%.The inbreeding coefficient (F IS ) low populations: Ipiranga = 0.147), Nova Esperança 0.094) Promissão 0.108).Genetic differentiation among...
Abstract In Argentina, wild pigs ( Sus scrofa ) are represented by boars and feral pigs. These populations inhabit a wide territory due to natural dispersion human translocation. Previous studies in other countries have detected crossbreeding between the different morphotypes, even with domestic This crossing can lead introgression of improved traits population, which would increase invasive potential and, therefore, damage native ecosystems. The aim this work was obtain patterns genetic...
Summary Relatively large rates of response to traits economic importance have been observed in different selection experiments salmon. Several QTL mapped the salmon genome, explaining unprecedented levels phenotypic variation. Owing relatively intensity, individual loci may be indirectly selected, leaving molecular footprints selection, together with increased inbreeding, as its likely relatives will share selected loci. We used population differentiation and linkage disequilibrium...
Abstract In this study, we conducted a survey of newly discovered populations tuco-tuco (subterranean rodents the genus Ctenomys ) in Entre Ríos province, an area characterized by its unexplored nature and climatic biogeographic complexity within Argentina, which includes two National Parks. We characterize nucleotide sequences cytochrome-b gene, revealing presence seven novel haplotypes rionegrensis , species known to inhabit both sides Uruguay River. Through Bayesian analyses, estimated...
Porcine Stress Syndrome (PSS) is a disorder codified by the ryanodine receptor 1 gene (RYR1) and affects both animal welfare quality of meat product. As consequence, individuals with this syndrome generate great worldwide economic losses in porcine industry. In Argentina, Buenos Aires Province most involved on activity, productions are to be open field higher frequency pigs diverse pathologies. On other hand, biggest oldest wild population located Atlantic coast Province, which presents...
Crespa goats are phenotypically similar to the Angora breed, and traditionally reared in small, low-tech farms southernmost Brazil. Whether they represent degenerated remnants of pure or result from foreign breeds introduced during colonial times recently mixed with commercial is unknown. Since degree relatedness relation other completely unknown, we performed a comparative assessment genetic similarity between region (Angora, Alpine, Anglo-Nubian, Boer, Saanen), particularly Angora. We used...
Abstract The biogeographic history of a species results from responses to past and current processes, understanding those at both temporal scales is essential. We explored phylogeographic genetic variation structure in Ctenomys flamarioni—a subterranean rodent that inhabits small region the coastal plain Brazil—and contrasted roles “present-day niche suitability” versus “historical climate stability” understand intraspecific diversity. used mitochondrial DNA sequences (concatenated Cytb...
Subterranean rodents of the genus Ctenomys (tuco-tucos) are endemic to South America and have experienced relatively recent radiation. There about 67 recognized species that originated in approximately 1-2 MY. They stand out for their richness, extraordinary chromosomal diversity, wide distribution. Phylogenetic relationships among tuco-tucos been challenging resolve. Groups closely-related suggested, but must be resolved. This study estimates phylogeny using massive sequencing, generating...
The puma ( Puma concolor Linnaeus, 1771) is the top predator with widest distribution in America. Since establishment of European settlers on American continent, populations have experienced significant contractions and reductions their original distribution. In Argentina, management conflict between humans pumas (direct persecution habitat modification) focused reduction or elimination methods, leading to a drastic contraction, even total eradication, as seen Patagonia eastern part country....
