Project description:The site of Nunalleq has yeilded remarkably well preserved archaeological artefacts, which have provided insight into the lifeways of humans and dogs in pre-contact Alaska. Dietary studies using stable isotopes have revealed a mixed economy relying heavily on aquatic resources, but while similarities between human and dog provisioning are apparent, the broad perspectives provided by stable isotope analysis leaves questions concerning the management of dogs in the past open for interpretation. This dataset was generated to explore the viability of performing palaeoproteomic analyses on palaeofaeces, something which, at the time we started, had yet to be published on, and to explore the short term insights from dog faeces in high resolution using a combination of shotgun proteomics and zooarchaeology by mass spectrometry.

Project description:The Italian island of Sardinia is well known in studies of human population isolates. It is also home to the Fonni's Dog, a breed of canine whose development was reliant on the functionality of the dog. Using genome-wide variant and sequence analyses, we have characterized the Fonni's Dog relative to 27 other dog breeds from the Mediterranean region. We determine introgression events relevant to Mediterranean breed development and describe how the Fonni's dog presents an intriguing model demonstrating the characteristics of traditional human population isolates and, in particular, exhibiting the unique demographic composition of the people of Sardinia.

Project description:This study used the NimbleGen dog whole genome CGH 2.1M tiling array to assay copy number variants in the dog genome in multiple breeds and wolf.
Project description:Through thousands of years of breeding and strong human selection, the dog (Canis lupus familiaris) exists today within hundreds of closed populations throughout the world, each with defined phenotypes. A singular geographic region with broad diversity in dog breeds presents an interesting opportunity to observe potential mechanisms of breed formation. Italy claims 14 internationally recognized dog breeds, with numerous additional local varieties. To determine the relationship among Italian dog populations, we integrated genetic data from 263 dogs representing 23 closed dog populations from Italy, seven Apennine gray wolves. Using 142,840 genome-wide SNPs, this dataset was used in the identification of breed development routes for the Italian breeds that included divergence from common populations for a specific purpose, admixture of regional stock with that from other regions, and isolated selection of local stock with specific attributes.
Project description:We report the sequences bound to CENP-A in the dog genome (Canis familiaris) for high-throughput characterization of centromeric sequences. We compare these ChIPSeq reads (72 bp, single read) against a reference centromeric satellite DNA domain database for the dog genome, resulting in the annotation of sequence variation and estimated abundance of seven satellite families together with adjacent, non-satellite sequences. To study global patterns of sequence diversity and characterizing the subset of sequences correlated with centromere function, these sequences were evaluated relative to a comprehensive centromere sequence domain k-mer library. From this analysis, we identify functional sequence features from two satellite families (CarSat1 and CarSat2) that are defined by distinct arrays subtypes.
