Title Behavioral patterns and proximate reason of young male separation in Misaki feral horses Type Journal Article
Year 1997 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 54 Issue 4 Pages 281-289
Keywords Misaki feral horse; Horse maternal-filial bond; Social behavior; Separation season; Separation reason
Abstract The present investigation was undertaken to study the proximate reasons why and the behavioral patterns of young male Misaki feral horses when they left their natal band or mothers. We observed a total of ten young males twice a month from January 1988 to December 1995. Almost all young males left their natal band or mothers at between 1 and 4 years of age. We found that, during the separation process, all the young males from first parity dams returned several times after the initial separation, indicating a strong attachment between primiparous mares and their male offspring. The other five separated only once without rejoining. Our observations showed five variable behavior patterns of young males at separation time, depending on the consort relation between their mothers and harem stallion and the reason for separation at that time. Eight young males separated in the non-breeding season at average 2.1 years and the other two separated in the breeding season at average 3 years and the average difference was not significant. These results revealed that 80% of the young males separated voluntarily when the natural resources become poor whereas 20% separated when their siblings were born.

Title Cooperation and the Prisoner's Dilemma: towards testable models of mutualism versus reciprocity Type Journal Article
Year 1997 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 54 Issue 3 Pages 551-557
Keywords
Abstract For the purpose of distinguishing between mutualism and reciprocity in nature, recent work on the evolution of cooperation has both oversimplifed and undersimplified the distinction between these two categories of cooperation. This article addresses the resulting issues of model testability, clarifies the role of time and argues that the category of `pseudo-reciprocity' is an unnecessary complication.
