Data are presented supporting previous competition hypotheses. The frequency and intensity of encounters was highest during competition for resources that were limited and defendable. Activities associated with limited but undefendable resources were followed by fewer encounters which were of lower intensity. When unlimited and undefendable resources were involved, agonistic encounters were infrequent. Comparisons with earlier work show that patterns of agonistic behavior in groups of <em>Sus scrofa</em>, regardless of the environmental setting, are not simply related to the preceding activity per se, but are related systematically to the availability and distribution of resources associated with that activity. A short-term decrease in the tendency of one male to displace its rank neighbor, not encompassed by familiar notions of rank-neighbor relations, was discovered. A previously undescribed visual display used to prevent or inhibit aggression was observed.</p></div>","PeriodicalId":100106,"journal":{"name":"Applied Animal Ethology","volume":"10 4","pages":"Pages 291-300"},"PeriodicalIF":0.0,"publicationDate":"1983-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-3762(83)90180-3","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"100336737","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Population densities of approximately 400 dogs per square mile and a sex ratio of 3 males: 1 female were found for each of three study areas. Free-ranging dogs were typically large, owned individuals; strays were a monority. Of four different group types identified in this study (familiar, unfamiliar, people-mediated and estrous), the first three are described. The social organization during non-breeding periods was characterized by a majority of solitary individuals. The relatively few groups observed rarely contained more than two individuals. Familiarity between dogs was the primary basis of sociality, although the distance a dog was from its home-site, its body size, age and ownership status also influenced social behavior. There was no seasonal variation in these patterns. Aggression was rare and mutual avoidance was the primary spacing mechanism. However, of those agonistic interactions that did occur, unfamiliar dogs were involved 5–15 times more frequently than familiar dogs.</p><p>Home-range movements of individuals were largely restricted to areas around the home-site. Home-range size was correlated to a dog's ownership status much more than body size. There was no evidence of territoriality.</p><p>Resources such as food and shelter influenced the social organization by concentrating individuals in areas where these were available. Major, predictable changes in available food had no effect on social behavior. Likewise, environmental parameters such as human presence and weather conditions generally influenced dog behavior indirectly.</p></div>","PeriodicalId":100106,"journal":{"name":"Applied Animal Ethology","volume":"10 4","pages":"Pages 341-363"},"PeriodicalIF":0.0,"publicationDate":"1983-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.1016/0304-3762(83)90184-0","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91350183","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
