The genome of the zebra finch — a songbird and model for study vertebrate brain, behaviour evolution has been sequenced. Its comparison with chicken genome, only other bird available, shows that genes neural function implicated in cognitive processing song have rapidly evolving lineage. also vocal communication engages much brain transcriptome identifies potential integrator microRNA signals linked to communication. studying Comparison are Moreover, brain. is an important organism several...
International agreements such as the Convention on Biological Diversity (CBD) have committed to conserve, and sustainably equitably use, biodiversity. The CBD is a vital instrument for global conservation because it guides 195 countries European Union in setting priorities allocating resources, requires regular reporting progress. However, similar policy often neglected genetic diversity. This critical gap diversity underlies adaptation environmental change ecosystem resilience. Here we aim...
Abstract The genes of the major histocompatibility complex (MHC) code for proteins involved in antigen recognition and triggering adaptive immune response, are therefore likely to be under selection from parasites. These regimes may vary space time. Here we report a strong geographical structure MHC class II B migrating bird, great snipe ( Gallinago media ). Genetic differentiation between two ecologically distinct distributional regions (Scandinavian mountain populations vs. East European...
Due to its high polymorphism and importance for disease resistance, the major histocompatibility complex (MHC) has been an important focus of many vertebrate genome projects. Avian MHC organization is particular interest because chicken Gallus gallus, avian species with best characterized MHC, possesses a highly streamlined minimal essential which linked resistance against specific pathogens. It remains unclear extent this describes situation in other birds whether it represents derived or...
Genetic approaches have proved valuable to the study and conservation of endangered populations, especially for monitoring programs, there is potential further developments in this direction by extending analyses genomic level. We assembled genome wolverine (Gulo gulo), a mustelid that Scandinavia has recently recovered from significant population decline, obtained 2.42 Gb draft sequence representing >85% including >21,000 protein-coding genes. then performed whole-genome resequencing 10...
Abstract Genetic diversity is one of the three main levels biodiversity recognised in Convention on Biological Diversity (CBD). Fundamental for species adaptation to environmental change, genetic nonetheless under‐reported within global and national indicators. When it reported, focus often narrow confined domesticated or other commercial species. Several approaches have recently been developed address this shortfall reporting wild While multiplicity helpful any development process, can also...
Abstract Genes of the major histocompatibility complex (MHC) play a part in activation vertebrate immune system. In addition, they also appear to function as cues for mate choice. mammals especially, several kinds MHC‐dependent choice have been hypothesized and observed. These include mates that share no or few alleles with choosing individual, differ much possible from heterozygous mates, certain genotypes rare alleles. We investigated these different aspects relation MHC lekking bird...
Microsatellites are widely used for many genetic studies. In contrast to single nucleotide polymorphism (SNP) and genotyping-by-sequencing methods, they readily typed in samples of low DNA quality/concentration (e.g. museum/non-invasive samples), enable the quick, cheap identification species, hybrids, clones ploidy. also have highest cross-species utility all types markers genotyping, but, despite this, when isolated from a only relatively small proportion will be utility. Marker...
Genome and transcriptome sequencing applications that rely on variation in sequence depth can be negatively affected if there are systematic biases coverage. We have investigated patterns of local coverage by utilising ultra-deep (>100,000X) mtDNA obtained during two vertebrate genomes, wolverine (Gulo gulo) collared flycatcher (Ficedula albicollis). With such extreme depth, stochastic should negligible, which allows us to provide a very detailed, fine-scale picture dependent error...
Several factors affect the flight altitude of migratory birds, such as topography, ambient temperature, wind conditions, air humidity, predation avoidance, landmark orientation, and avoiding over-heating from direct sunlight.1-6 Recent tracking birds over long distances has shown that migrants change more commonly dramatically than previously thought.4-8 The reasons behind these changes are not well understood. In their seasonal migrations between Sweden sub-Saharan Africa, great snipes...
Abstract Genetic diversity is essential for maintaining healthy populations and ecosystems. Several approaches have recently been developed to evaluate population genetic trends without necessarily collecting new data. Such “genetic indicators” enable rapid, large-scale evaluation across dozens thousands of species. Empirical studies, when available, provide detailed information that important management, such as estimates gene flow, inbreeding, erosion adaptation. In this article, we argue...
Avian beta-defensins (AvBDs) represent a group of innate immune genes with broad antimicrobial activity. Within the chicken genome, previous work identified 14 AvBDs in cluster on chromosome three. The release second bird zebra finch, allows us to study comparative evolutionary history these gene clusters between from two species that shared common ancestor about 100 million years ago.A phylogenetic analysis beta-defensin and finch several cases duplication loss along their ancestral lines....
The different regions of a genome do not evolve at the same rate. For example, comparative genomic studies have suggested that sex chromosomes and harbouring immune defence genes in Major Histocompatability Complex (MHC) may faster than other regions. advent next generation sequencing technologies has made it possible to study which are evolutionary liable change static, as well enabling an increasing number non-model species. However, de novo whole organism remains non-trivial. In this...
Genes of the immune system are generally considered to evolve rapidly due host–parasite coevolution. They therefore great interest in evolutionary biology and molecular ecology. In this study, we manually annotated 144 avian genes from zebra finch (Taeniopygia guttata) genome conducted analyses these by comparing them with their orthologs chicken (Gallus gallus). classified as receptors showed elevated dN/dS ratios compared other classes genes. Immune general also appear be evolving more...
In order to understand patterns of adaptation and molecular evolution it is important quantify both variation in gene expression nucleotide sequence divergence. Gene profiling non-model organisms has recently been facilitated by the advent massively parallel sequencing technology. Here we investigate tissue specific zebra finch (Taeniopygia guttata) with special emphasis on genes major histocompatibility complex (MHC).Almost 2 million 454-sequencing reads from cDNA six different tissues were...
The migration of the great snipe Gallinago media was previously poorly known. Three tracks in 2010 suggested a remarkable migratory behaviour including long and fast overland non‐stop flights. Here we present pattern Swedish male snipes, based on 19 individuals tracked by light‐level geolocators four different years. About half birds made stopover(s) northern Europe early autumn. They left breeding area 15 d earlier than those which flew directly to sub‐Sahara, suggesting two distinct autumn...
