Testing for selection is becoming one of the most important steps in analysis multilocus population genetics data sets. Existing applications are difficult to use, leaving many non-trivial, error-prone tasks user. Here we present LOSITAN, a detection workbench based on well evaluated F st -outlier method. LOSITAN greatly facilitates correct approximation model parameters (e.g., genome-wide average, neutral ), provides import and export functions, iterative contour smoothing generation...
The human genome project has been recently complemented by whole-genome assessment sequence of 32 mammals and 24 nonmammalian vertebrate species suitable for comparative genomic analyses. Here we anticipate a precipitous drop in costs increase sequencing efficiency, with concomitant development improved annotation technology and, therefore, propose to create collection tissue DNA specimens 10 000 specifically designated the very near future. For this purpose, we, Genome 10K Community...
Noninvasive genetic approaches continue to improve studies in molecular ecology, conservation genetics and related disciplines such as forensics epidemiology. sampling allows without disturbing or even seeing the target individuals. Although noninvasive has been used for wildlife since 1990s, technological advances make among most rapidly advancing areas genetics. Here, we review recent how they allow us address important research management questions thanks improved techniques DNA...
Cattle domestication from wild aurochsen was among the most important innovations during Neolithic agricultural revolution. The available genetic and archaeological evidence points to at least two major sites of in India Near East, where zebu taurine breeds would have emerged independently. Under this hypothesis, all present-day European be descended cattle domesticated East subsequently spread diffusion herding farming lifestyles. We present here previously undescribed contrast with view,...

Most hosts are infected with multiple parasites, and responses of the immune system to co‐occurring parasites may influence disease spread. Helminth infection can bias host response toward a T‐helper type 2 (Th2) over 1 (Th1) response, impairing host’s ability control concurrent intracellular microparasite infections potentially modifying dynamics. In humans, immune‐mediated interactions between helminths microparasites alter susceptibility diseases such as HIV, tuberculosis (TB), malaria....
Genetic data from extant donkeys ( Equus asinus ) have revealed two distinct mitochondrial DNA haplogroups, suggestive of separate domestication events in northeast Africa about 5000 years ago. Without phylogeographic structure domestic donkey haplogroups and with little information on the genetic makeup ancestral African wild ass, however, it has been difficult to identify ancestors geographical origins for clades. Our analysis ancient archaeological historic museum samples provides first...
Gene-targeted and genome-wide markers are crucial to advance evolutionary biology, agriculture, biodiversity conservation by improving our understanding of genetic processes underlying adaptation speciation. Unfortunately, for eukaryotic species with large genomes it remains costly obtain genome sequences develop resources such as SNPs. A method is needed allow gene-targeted, next-generation sequencing that flexible enough include any gene or number genes, unlike transcriptome sequencing....
Donkeys transformed human history as essential beasts of burden for long-distance movement, especially across semi-arid and upland environments. They remain insufficiently studied despite globally expanding providing key support to low- middle-income communities. To elucidate their domestication history, we constructed a comprehensive genome panel 207 modern 31 ancient donkeys, well 15 wild equids. We found strong phylogeographic structure in donkeys that supports single Africa ~5000 BCE,...
Novel species of fungi described in this study include those from various countries as follows: Argentina , Neocamarosporium halophilum leaf spots Atriplex undulata . Australia Aschersonia merianiae on scale insect ( Coccoidea ), Curvularia huamulaniae isolated air, Hevansia mainiae dead spider, Ophiocordyceps poecilometigena Poecilometis sp. Bolivia Lecanora menthoides sandstone, open semi-desert montane areas, Sticta monlueckiorum corticolous a forest, Trichonectria epimegalosporae...
The origin of Iberian cattle has been suggested by some authors to be the product European and north African entrances during last few thousands years. However, these hypotheses were mainly based on morphological similarities. This study analyzed 889 unrelated individuals from 15 representative breeds 3 French for 16 microsatellite loci. Statistical tests used calculate interpopulation genetic distances (DA) principal components analysis (PCA). To visualize geographical distribution...
Identifying the source of infectious disease outbreaks is difficult, especially for pathogens that infect multiple wildlife species. Brucella spp. are among most problematic zoonotic agents worldwide, and they notoriously difficult to detect identify. We genotyped 10 variable number tandem repeat (VNTR) DNA loci in 56 abortus isolates from bison (Bos bison), elk (Cervus elaphus), cattle taurus) test species likely be origin recent brucellosis Greater Yellowstone Area. Isolates were nearly...
Several studies have investigated the differentiation of mitochondrial DNA in Eurasian, African and American cattle as well archaeological bovine material. A global survey these shows that haplogroup distributions are more stable time than space. All major migrations shifted considerably with a reduction number haplogroups and/or an expansion haplotypes rare or absent ancestral populations. The most extreme case is almost exclusive colonization Africa by T1 haplogroup, which Southwest Asian...
Type 2 diabetes mellitus (T2DM) is a chronic metabolic disease that becoming significant global health care problem. Several studies have shown people with are more susceptible to oral problems, such as periodontitis and, although the causes still inconclusive, microbiota considered play major role in health. This study aimed characterize microbiome of sample representing T2DM patients from Portugal and exploit potential associations between some microorganisms variables like teeth brushing,...
Five cattle Y-specific microsatellites, totalling six loci, were selected from a set of 44 markers and genotyped on 608 Bos taurus males belonging to 45 populations Europe Africa. A total 38 haplotypes identified. Haplogroups (Y1 Y2) previously defined using single nucleotide polymorphisms did not share haplotypes. Nine the 27 Y2-haplotypes only present in African cattle. Network correspondence analyses showed that this African-specific subfamily clustered separately main Y2-subfamily Y1...
Summary Donkey domestication drastically changed ancient transport systems in A frica and sia, enabling overland circulation of people goods influencing the organization early cities pastoral societies. Genetic studies based on mt DNA have pointed to frican wild ass as most probable ancestor domestic donkey, but questions regarding its center origin remain unanswered. Endeavoring pinpoint geographical we assessed levels patterns genetic diversity at 15 microsatellite loci from eight...
Despite a number of recent studies that have focused on the origin domestic horses, genetic relationships between major geographical clusters still remain poorly understood. In this study we analyzed 296 bp mtDNA fragment from HVI region 171 horses representing 11 native Iberian, Barb, and Exmoor breeds to assess maternal phylogeography Iberian horses. The haplogroup with CCG motif (nucleotide position 15,494 15,496) was most frequent in Barb (0.42 0.57, respectively), regardless geographic...
