1. Arief, Riana Aryani. Dog demography and population estimates for rabies control in Bali, Indonesia.

Degree: MS(M.S.), Clinical Sciences, 2014, Colorado State University

Rabies is a fatal zoonotic disease with global significance. At the end of 2008, rabies emerged in the Island of Bali, Indonesia, drawing international attention. As the disease became wide-spread, the government focused on island-wide mass vaccination of dogs and improving public awareness, however the local dog population is not well documented. The Center for Indonesian Veterinary Analytical Studies (CIVAS), a local non-government organization in Indonesia, and the International Livestock Research Institute (ILRI) initiated a project to explore the link between the dog population and local communities in Bali with focus on the impact of this relationship in the spread of rabies. As part of that project, the objective of the study is to (1) characterize the demographics and rabies vaccination of owned and free-roaming dogs and (2) estimate the abundance and identify factors associated with the distribution of the dogs in Bali. The study was conducted on two dog subpopulations, owned and free-roaming dogs, in 310 banjars in Denpasar city, Gianyar district, and Karangasem district in Bali. Banjar is a subvillage structure in Bali. The sampling design was a two-stage sampling with villages as the primary sampling unit and banjars as the secondary sampling unit. Data were collected between March 2011 and March 2012. Survey of owned dogs was carried out through door to door interview of owners and photographic mark recapture was used to collect data on free-roaming dogs. Dogs were predominantly owned and the effect of unowned dogs towards the total population was minimal. Demographically, the sex ratio was male-biased and juveniles make up 15-20% of the population. Free-roaming dogs were dominated by adults and a higher proportion of males. There were differences in the demographics of dogs in urban and non-urban areas which should be considered when planning and implementing control programs. Overall vaccination coverage was high (>70%), however juveniles and females have a higher likelihood of not being vaccinated. The endurance of vaccination collars should be improved to better represent the true vaccination coverage in free-roaming dogs as there is high confidence that most free-roaming dogs were actually owned dogs. Recent culling was associated with increased proportions of juveniles and a 40% higher risk of dogs not being vaccinated. The observation of free-roaming dogs should always account for detection probability as only 20% of dogs in this study were seen at any given time. Failure to account for detection probability will result in severe underestimation of the population abundance. The human population, presence of a forest and recent culling accounted for 28% of variation in the number of owned dogs in banjars. Accordingly, the number of owned dogs and presence of rice paddies accounted for 61% of variation in the number of free-roaming dogs in banjars. Finally, the overall and median human to dog ratios were the least biased ratios available for estimating the overall dog population, however it… Advisors/Committee Members: Salman, M. D.

2. Kisiel, Luz Maria. Using a dog demography field study to inform the development of an agent-based computer simulation. Evaluating owned dog population control interventions in a small, semi-urban community in Mexico.

Degree: MS, Department of Population Medicine, 2017, University of Guelph

This thesis evaluates the potential effects of different dog population control interventions in a small, semi-urban community in Mexico. First, a cross-sectional study was conducted to characterize dog ecology and demography in Villa de Tezontepec, Hidalgo. Approximately 65% of the households owned one or more dogs. The majority of owned dogs (76%) were not sterilized, and less than half (45%) were kept confined. Second, a stochastic, agent-based simulation model was constructed to determine the projected impact of surgical sterilization interventions and increased dog confinement on the owned dog population size for this community. The model outputs suggested that surgical sterilization interventions focused only on young dogs (prior to sexual maturity) could yield greater reductions in population size than surgical interventions focused on dogs of mixed age. The information generated in this thesis can help to identify considerations for the design and implementation of dog population control programs in developing countries.

3. Witt Dillon, Kelsey E. A demographic and dietary history of ancient dogs in the Americas using ancient DNA.

Degree: PhD, Ecol, Evol, Conservation Biol, 2017, University of Illinois – Urbana-Champaign

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.
