▼ In the early days of genomics, the development of a reference genome was an expensive, collaborative undertaking reserved only for traditional and popular model organisms; however, in a theoretical shift highlighted most clearly by the goals of the Genome 10K Project, the advent of next-generation sequencing (NGS) technology has resulted in a shift of focus towards the development of reference genomes for a variety of species less commonly studied. One non-traditional model organism selected as a priority species for the Genome 10K Project is the red fox (Vulpes vulpes), and specifically a fox from an experimental breeding project in which silver foxes (a melanistic variant of the red fox) have been selected over the past several decades to exhibit extreme behavioral phenotypes. The population consists of a strain of hyper-aggressive foxes and a strain of hyper-docile foxes, offering a model system through which the genetic underpinnings of behavior, as well as the genetic correlates of domestication, can be investigated.
The draft red fox genome, which was developed at BGI, has a sequence depth of 94x and is assembled into 676,878 scaffolds with an N50 of 11.80 Mbp. However, in order for the reference genome to be integrated with previous work in the model system, it is necessary to understand the relationship between the scaffolds and the chromosomes they comprise. Therefore, the primary goal of the present study was to assemble the fox chromosomes from the scaffolds of the draft red fox genome assembly.
The draft genome was first analyzed to detect bioinformatic errors known to occur in NGS-assembled genomes that might influence the integrity of the chromosome assembly. Based on these findings, the 500 largest scaffolds were assembled into the 17 fox chromosomes (16 autosomes and the X) based both on nucleotide-level synteny among the fox, dog, and cat identified through pairwise alignment of the reference genomes and on interspecies synteny reported in previously developed comparative maps. The result of the current analysis is the development of a new version of the red fox reference genome that will serve as a valuable tool in ongoing research by increasing the resolution at which mapping studies can probe the genetic architecture of complex behavioral phenotypes in the domesticated fox system.

▼ A single nucleotide polymorphism in insulin-like growth factor 2 (IGF2 intron3-G3072A) is associated with greater muscle mass and decreased subcutaneous fat deposition in pigs carrying a paternal copy of the A allele (Apat). While many studies have focused on the differences in between the gross phenotypes of these animals, relatively little has been done to understand how these animals differ at the molecular level. It was the objective of this study to compare the molecular phenotypes of animals carrying the Apat allele and those carrying the Gpat allele in order to gain insight into how those differences may result in the differences seen at the whole-animal level. RNA was extracted from longissimus (LM) samples taken from six animals of each genotype (Apat and Gpat) at four different time points, fetal day 90 (d90), birth (0d), weaning (21d), and market weight (176d). In total 46 samples were sequenced on the Illumina HiSeq 2000 with a target depth of 20 million reads per sample. Analysis of the RNA-seq data using tweeDEseq determined differentially expressed genes between Apat and Gpat pigs at each time point. Additionally, IPA analysis was used to determine if there were any differentially activated pathways between the two phenotypes. IGF2 was not found to be upregulated in Apat pigs compared to Gpat at d90 or 0d; however, IGF2 expression was found to be increased in Apat pigs compared to Gpat pigs at 21d and 176d. Though there was not differential expression of IGF2 at d90 and 0d, there was still differential expression of several other genes at these time points. At d90, Apat pigs tended to have an increase in the expression anti-apoptotic genes and a decrease in pro-apoptotic genes, possibly indicating enhanced myoblast survival, while Gpat pigs had greater expression of genes associated with protein synthesis. At 0d, there was an increased expression of genes associated with proliferation and protein synthesis in Apat pigs, and Gpat pigs appeared to have upregulation of genes involved in inflammation. At both 0d and 21d Apat and Gpat pigs had displayed upregulation of markers of myogenesis, suggesting different stages of muscle development. At 176d, Apat animals had decreased expression of genes involved in adipose signaling, including inflammation, stress, and autophagy and greater expression of genes associated with tissue development and the cell cycle. Thus, throughout the developmental timepoints, there appear to be markedly different processes taking place in the muscle tissue of Apat pigs and Gpat pigs.

▼ Strains of red fox (Vulpes vulpes) with markedly different behavioral phenotypes have been developed in the famous long-term selective breeding program known as the Russian farm-fox experiment. Here we sequenced and assembled the red fox genome and re-sequenced a subset of foxes from the tame, aggressive, and conventional farm-bred populations to identify genomic regions associated with the response to selection for behavior. Analysis of the resequenced genomes identified 113 regions with either significantly decreased heterozygosity in one of the three populations or increased divergence between the populations. A strong positional candidate gene for tame behavior was highlighted: SorCS1, which encodes the main trafficking protein for AMPA glutamate receptors and neurexins and suggests a role for synaptic plasticity in fox domestication. Other regions identified as likely to have been under selection in foxes during domestication include genes implicated in human neurological disorders, in mouse behavior, and in dog domestication. The fox represents a powerful model for the genetic analysis of affiliative and aggressive behaviors that can benefit genetic studies of behavior in dogs and other mammals, including humans.

▼ Variation in activity of the hormonal stress response, or hypothalamic-pituitary-adrenal (HPA) axis, has been associated with different personality traits and coping styles in humans and animals, while its dysregulation has been implicated in psychological disorders. The molecular basis of HPA axis regulation, however, is not yet well understood. Here, foxes selectively bred for tameness or aggression are used as a model to investigate differences in regulation of the HPA axis. Activity of this axis is markedly reduced in tame compared to aggressive foxes, with reduced levels of HPA axis hormones such as adrenocorticotrophic hormone (ACTH) and cortisol both basally and in response to a stressor. Gene expression differences were analyzed using RNA sequencing in the anterior pituitary and adrenal glands of foxes from the tame and aggressive lines, and variant analysis was performed on RNA reads from hypothalamus, anterior pituitary, and adrenal tissues from the same foxes. Pituitary analysis revealed expression differences in genes related to exocytosis and cellular signaling; adrenals analysis identified differences in similar pathways, in addition to genes related to fatty acid and cholesterol synthesis. Variant analysis also implicated cell signaling and exocytosis, as well as ion transport and DNA damage repair. These findings suggest the importance of regulation of hormone release in the control of ACTH and cortisol levels. They also suggest that metabolism of precursors to cortisol, such as fatty acids and cholesterol, may be of greater importance in HPA axis regulation than synthesis of cortisol itself. Finally, in conjunction with previous genomic findings, they suggest an association between DNA repair mechanisms and selection for tameness. These findings provide possible new lines of investigation into biological underpinnings of the phenotypic differences between the tame and aggressive lines of foxes. More broadly, as the tame foxes are considered experimentally domesticated, the findings from this project may prove applicable to HPA axis regulation differences associated with domestication in other species. Additionally, a deeper understanding of HPA axis regulation and dysregulation may be applicable both to variation in the normal population, particularly as related to behavioral traits such as coping styles, and to a number of psychiatric disorders in humans, as well as to behavioral disorders in other species, such as dogs.

▼ Dogs were domesticated more than 15,000 years ago, and since then they have become an integral part of human lives. They have served as hunters, guards, and pets, and have migrated with humans to multiple continents, including the Americas and Australia. The close relationship between humans and dogs makes dogs a valuable proxy when studying human history. In this study, we use ancient dog remains from the Americas to gain an understanding of their demographic and dietary history, as well as that of humans. Mitochondrial DNA sequences of the hypervariable region of ancient dogs were compared to modern and ancient American dogs to model dog demography and compare populations to identify shared haplotypes. This study identified multiple founding haplotypes, and suggested that dogs arrived to the Americas after the initial human migration. The majority of published ancient American dog DNA sequences is of the hypervariable region, so this comparison gives us the opportunity to look at the largest number of dogs across the Americas. We also sequenced complete mitochondrial genomes (mitogenomes), to determine if mitogenome data could be used to confirm the hypotheses made about ancient American dog demography using the hypervariable region. Mitogenome sequences show a higher-resolution perspective on dog diversity, and the longer sequences revealed different aspects of dog demography. We were able to support the hypotheses that suggest that dogs migrated to the Americas with humans, and that dog populations vary in genetic diversity, but were not able to support the hypotheses that ancient and modern dogs show continuity, and that dogs arrived to the Americas later in time. We also found that ancient dog demography mirrors ancient Native American demography in specific regions of North America, such as the Pacific Coast and Southeast. Finally, we assessed the diet in dogs from the American Bottom using both stable isotopes and shotgun sequencing of dog coprolites, and used the findings about dog diet to infer human diet during the Late Woodland and Mississippian periods. We found that dogs (and humans) ate no maize during the Late Woodland Period, but were consuming large amounts of maize as early as 1010 AD, and maize was likely present in the American Bottom by 900 AD. Additionally, Mississippian dogs and humans supplemented their diet of maize with other foods including squash and fish. The analysis of the history of dogs has yielded a wealth of information about how dogs and humans interacted in the Americas.

▼ Cognition encompasses important mechanisms with which animals are able to adjust their behavior in response to environmental cues. These cognitive processes play a clear role in many fitness-related behaviors such as foraging, predator avoidance, and courtship. Thus, how these processes have evolved are of key scientific interest. Historically, research on the evolution of cognitive traits has largely focused on variation between species. However, particularly in the last couple of decades, there has been increasing interest in examining variation in cognition within a species. These studies no longer look at intraspecific variation as noise, but see it as being potentially adaptive and therefore impacting evolutionary trajectories. Yet, while many of these studies seemingly demonstrate the benefits of different cognitive traits, this has inevitably led to questions about why intraspecific variation is maintained. How costly are these traits? Are there trade-offs that maintain variation?
The aim of the research in this dissertation is to study the mechanisms that drive and maintain intraspecific variation in cognition in threespined sticklebacks. This is done from four different angles. First, I tested the hypothesis that learning is part of an overall suite of correlated traits related to how an individual copes with changes in the environment, and that trade-offs between early learning and responsiveness to changes in learning outcomes may maintain cognitive variation. I found that individuals that showed a higher cortisol stress response and that were more reactive to a predatory threat were slower to learn a novel discrimination task, but not necessarily faster to respond when learning conditions changed. Second, I tested the hypothesis that sticklebacks from populations inhabiting different environments are primed to learn different cue associations faster within novel learning conditions. When individuals from two separate populations were trained on either a color vs. spatial discrimination task, the two populations excelled on different tasks: fish from a river habitat performed significantly better on the side version than they did on the color version, while the opposite was observed in fish from a pond habitat. Third, I explored the underlying causes of why some individuals are more responsive than others when there is a change in learning outcomes (i.e., differences in behavioral flexibility) by asking whether individual differences in reversal learning performance were more strongly associated with variation in boldness, neophobia and/or inhibitory control. I found that early performance on reversal learning trials was associated with all three behavioral traits, while time to criterion during reversal learning was independent of the other behaviors. Finally, I took advantage of the radiation of sticklebacks to ask whether behaviors predicted to facilitate adaptation to new environments (i.e., neophilia and inhibitory control) have evolved as stickleback have repeatedly colonized freshwater environments…
