RESERVATION DOGS: OCCUPANCY, COMMUNITY BELIEFS, AND LAKOTA WAYS OF KNOWING

Camille L Griffith (14227979) 08 December 2022 (has links)
<p>  </p> <p>Free-roaming dogs on Native American Reservations are called rez dogs on the Pine Ridge Indian Reservation, SD. Understanding the human-rez dog relationship is needed to develop best management practices. As a member of the Oglala Lakota nation and a resident of the Pine Ridge Indian Reservation, I used a combination of western scientific methods and Lakota ways of knowing to research how rez dogs are related to their human caretakers on the Pine Ridge Reservation. First, I determined how they are related to humans spatially. To do this, I installed trail cameras at 73 sites distributed within four zones around six communities on the Pine Ridge Reservation. I analyzed presence-absence and count data to estimate how human habitat covariates influenced rez dog occurrence and abundance. My results show that rez dog occupancy and abundance is related to human habitation and emphasizes the importance of considering human caretakers when developing best management practices. To investigate how human caretakers may perceive rez dogs and current management practices on the Pine Ridge Reservation, I used semi-structured questionnaires. I distributed surveys to 107 residents at grocery stores and convenience stores within five towns. The survey assessed the communities' perceptions of rez dog overpopulation, and topics related to their attitude toward dogs overall and rez dog sterilization programs. I used ordinal regression to determine if community member demographics, the number of people and dogs in the household, and distance to the veterinary clinic influenced these variables. My results show community members support rez dog sterilization programs and that policymakers should focus on free or low-cost sterilization programs for ambiguously owned rez dogs in conjunction with owned dogs. In addition, these results highlight how the economic disparity and lack of culturally appropriate methods of rez-dog population control prevent effective management of rez dogs. This dynamic is one example of how the settler-colonialism structure continues to negatively impact Native American communities and prevent effective, efficient, and ethical ways to manage rez dogs. I describe how the Lakota ways of knowing can be used to develop best management practices for rez dogs that are culturally appropriate. I describe the seven Lakota values, lessons learned from the Lakota dog creation story, and approaches to Lakota research methodologies. This paper introduces an example of a seven-generation, One Health framework that implements Lakota ways of knowing to establish rez dog management and centers community values, beginning generational healing through <em>Shunka </em>(dog) caretaking. In conclusion, this research describes how rez dogs are related to us spatially, by occupying the same area as us, and how we are related within a social context, with dogs being an indicator of our own well-being as humans. </p>

Interactions spatiales et temporelles entre les chiens libres et les carnivores sauvages à proximité des villages nordiques du Nunavik dans un contexte de transmission d’une maladie zoonotique : la rage

Frenette, Marie-Christine 04 1900 (has links)
Dans l'Arctique, le risque de transmission de maladies zoonotiques comme la rage est encore une préoccupation pour la santé publique, avec plusieurs cas rapportés chaque année chez différentes espèces animales. L’interface entre la faune sauvage, les animaux domestiques et les humains pour la transmission de maladies sera en augmentation en raison des pressions grandissantes du développement anthropique et du réchauffement climatique. Les interactions directes entre les chiens domestiques des villages nordiques et les renards sauvages, les principales sources d’exposition à la rage, sont des évènements critiques pour l’exposition des humains au virus, mais très peu d’études se sont attardées à ce sujet. Les objectifs de ce projet sont 1- de décrire et de quantifier l’activité spatiale et temporelle des renards et des chiens libres et d’identifier les facteurs anthropiques et environnementaux qui influencent leur présence à proximité et dans les villages nordiques, 2- de quantifier les contacts directs et le potentiel d’interactions entre les renards et les chiens libres afin de mieux identifier les périodes et les zones avec un risque de transmission de la rage, 3- de comparer et discuter des résultats de l’activité des renards et des chiens libres et leur potentiel d’interactions entre les deux villages nordiques à l’étude et 4- d’identifier des méthodes de gestion pour diminuer les opportunités d’interactions entre les renards et les chiens libres. Afin de détecter la présence des deux carnivores, un réseau de caméras automatiques a été installé sur une grille spatiale autour et à l’intérieur de deux villages typiques du Nord, Kuujjuaq (près de la limite des arbres) et Inukjuak (à > 100 km de la limite des arbres). Pour chaque station caméra, différents facteurs anthropiques et environnementaux ont été évalués (distance au dépotoir, distance à l’aéroport, densité d’habitations, densité de chiens de traîneau, distance aux rues, distance à l’eau, indice de végétation). Les contacts directs et les indices d’interaction ont été calculés pour évaluer le potentiel d’interactions entre les renards et les chiens libres. Les opportunités d’interactions entre les renards et les chiens sont plus élevées à l’aube et au crépuscule pendant les mois d'octobre et de novembre en périphérie des deux villages, particulièrement près des chiens de traîneau et légèrement près du dépotoir municipal (KU) et de l’aéroport (IN). Les renards roux et les renards arctiques ont été observés à proximité et dans les deux villages, mais les renards roux sont plus souvent observés à Kuujjuaq (87% des observations) qu’à Inukjuak (renards arctiques : 74% des observations), ce qui reflète également des particularités biotiques et abiotiques uniques à chaque village. Les résultats suggèrent que les opportunités d’interactions entre les renards et les chiens représentent un risque d’exposition à la rage pour les chiens et les humains, et possiblement pour d’autres pathogènes nordiques transmissibles entre les chiens et la faune. Cependant, les évènements de contacts directs interspécifiques renard-chien sont rares et les opportunités d’interactions sont concentrées dans le temps et dans des zones restreintes, ce qui peut aider à cibler des mesures préventives visant à limiter les évènements de transmission. Cette étude fournit la première documentation sur l'activité des renards et leurs interactions avec les chiens libres dans les villages de l'Arctique. L’application d’une approche « Une seule Santé » devrait être utilisée pour prévenir ou diminuer le risque de transmission de la rage entre les renards et les chiens. / In the Arctic, the risk of transmission of zoonotic diseases like rabies is still a public health concern, with several cases reported each year in different animal species. The interface between wildlife, domestic animals and humans for disease transmission will be increasing due to pressures from anthropogenic development and global warming. Direct interactions between domestic dogs in northern communities and wild foxes, the main source of rabies exposure, are critical of human exposure to the virus, but very few studies have focused on this. The objectives of this project are 1- to describe and quantify the spatial and temporal activity of free-ranging dogs and foxes, and identify the anthropogenic and environmental factors that influence their presence near and within northern villages, 2- to quantify direct contacts and the potential for interactions between free-ranging dogs and foxes in order to better identify periods and areas of higher risk of rabies transmission, 3- to compare and contrast dog-fox activity and interactions between the two northern villages under study, and 4- to identify management methods to reduce opportunities for fox-dog interactions. To detect the presence of the two carnivores, we set up a network of automatic cameras near and within two typical northern villages, i.e., Kuujjuaq (near the tree line) and Inukjuak (> 100 km from the tree line). For each camera, different anthropogenic and environmental factors were evaluated (distance to the landfill, distance to the airport, density of dwellings, density of sled dogs, distance to streets, distance to water, vegetation index). Direct contacts and interaction index were calculated to assess the potential for interactions between foxes and free-roaming dogs. Interaction opportunities between foxes and dogs are more likely to occur at dawn and dusk during the months of October and November, and on the outskirts of both villages, particularly near sled dogs and slightly nearer to the landfill (KU) and the airport (IN). Red and Arctic foxes were observed in and around both villages, but red foxes were more frequently observed in Kuujjuaq (87% of observations) while Arctic foxes were more frequent in Inukjuak (74% of observations), which also reflects the biotic and abiotic particularities specific to each village. These results suggest that fox-dog contacts around and within the village are likely, posing a real risk of peri-domestic rabies transmission to dogs and humans, and possibly for other northern pathogens transmissible between wildlife and dogs. Nevertheless, interspecific direct contact events are rare and interaction opportunities are concentrated in time and space, which may help target preventive measures aimed at limiting transmission events. This study provides the first documentation on the activity of foxes and their interactions with dogs and humans in Arctic communities. Considering the potential risk-by-proximity described in our study, a “One Health” approach could be applied to prevent or lower fox-dog rabies transmission.
