Heterogeneity of hunting ability and nutritional status among domestic dogs in lowland Nicaragua

Abstract

In past and modern human societies, dogs have played an important role as hunting companions. Given considerable ethnographic evidence that dogs vary in their hunting abilities, this paper addresses the effects of key demographic variables, namely age and sex, on the amount of harvested game that dogs contribute in an indigenous Nicaraguan community. Controlling for variation in the time spent potentially hunting, male dogs and older dogs are significantly associated with greater harvests. These results may account for documented preferences for males in both archaeological and ethnographic contexts. Among societies in which dogs are used both as hunting companions and sources of food, the age-related delay in peak hunting ability also suggests a tradeoff that might explain the consumption of dogs shortly after they have reached adult size. Informant rankings of two cohorts of dogs indicate that residents of the community exhibit high agreement about the relative abilities of the dogs, and the rankings indicate that dogs from the same household exhibit comparable skill. There is little evidence that talented, highly-ranked dogs are provided a more nutritious diet, as measured by nitrogen-based and carbonbased isotopic analysis of hair samples. Overall, although dogs can be quite advantageous as hunting companions, this research suggests that the heterogeneity of hunting ability combines with the high mortality of dogs to impose risks on households that depend on dogs as a source of harvested meat.Canis lupus familiaris | life history theory | Mayangna | Miskito | stable isotopes

Craniomandibular Trauma and Tooth Loss in Northern Dogs and Wolves: Implications for the Archaeological Study of Dog Husbandry and Domestication

“…Bogoras [44] states that sled dogs in the Chukotka area decline after six to seven years of age, but some work until ten or eleven years old. Detailed quantitative studies of modern Nicaraguan hunting dogs reported an average age at death of 3.7 years, with only 11% of individuals reaching eight years of age [27]; similarly short lives for dogs are reported in other studies [45]–[48]. Data on average age at death for wild wolves is rare, but it appears that few reach seven to eight years of age [49], [50].…”

Pre-Neolithic evidence for dog-assisted hunting strategies in Arabia

“…This suggests complex dog-assisted hunting strategies on the Arabian Peninsula began in the Pre-Neolithic and may have been a critical part of successfully repopulating the interior after a long hiatus. In the future, archaeologists should consider the effects of hunting dogs on cost-benefit analyses and prey choice models (Koster 2008;Koster and Tankersley 2012;Perri 2014;. For example, the targeting of male prey species may be less about human intentionality of conserving females and more about innate prey choices by hunting dogs.…”

Subsistence Hunting with Mixed-Breed Dogs Reduces Hunting Pressure on Sensitive Amazonian Game Species in Protected Areas

“…Moreover, animals corralled in burrows or driven into streams require less ammunition because they are captured using smoke and machetes or other non-ballistic weapons (Koster 2009). However, the efficiency of hunting with dogs also varies greatly with the ability of the hunter to read the dog signs and the ability of the dog to identify, chase and corral prey (Koster & Tankersley 2012). This variability may account for the divergent findings of studies that compared the efficiency of hunting with dogs with that of other strategies in the Neotropics (see Koster 2009).…”
