Social Play Behavior, Marc Bekoff
Social Play Behavior, Marc Bekoff
Ethology Collection
Recent studies clearly indicate that animal play is an important behavioral phenotype, and that detailed analyses of the phenomenon are useful for furthering our understanding of the evolution of social behavior and the interaction of phylogeny, ecology, and behavioral development. This article is concerned mainly with evolutionary, ecological, and developmental aspects of social play behavior in mammals.
Aquatic Feeding By Moose: Selection Of Plant Species And Feeding Areas In Relation To Plant Chemical Composition And Characteristics Of Lakes, D. Fraser, E R. Chavez, J. E. Paleheimo
Aquatic Feeding By Moose: Selection Of Plant Species And Feeding Areas In Relation To Plant Chemical Composition And Characteristics Of Lakes, D. Fraser, E R. Chavez, J. E. Paleheimo
Feeding Behavior Collection
Aquatic feeding by moose was studied with emphasis on (i) the chemical composition of aquatic plants compared with terrestrial browse, (ii) the chemical composition of preferred and unpreferred aquatic plant species and (iii) characteristics of preferred feeding areas. Compared with woody browse, aquatic plants had much higher levels of sodium and iron, and similar levels of other nutrients tested. In a "cafeteria" selection experiment, moose consistently ate seven species of aquatic plants (preferred plants), consistently rejected five species (unpreferred plants), and gave an intermediate response to seven species. Preferred species had significantly higher sodium content. Those in the intermediate class …

The Origins Of Empathy And Altruism, Carolyn Zahn-Waxler, Barbara Hollenbeck, Marian Radke-Yarrow
The Origins Of Empathy And Altruism, Carolyn Zahn-Waxler, Barbara Hollenbeck, Marian Radke-Yarrow
Human and Animal Bonding Collection
We will describe theories and research that try to explain the development, especially in children, of sensitivity to the needs of others. Are children born with empathy? Is it instinctive or learned? What kinds of changes do humane feelings and behaviors undergo as children develop? How do the environments in which children are reared determine whether they will be more or less likely to show concern and to assume responsibility for the welfare of others? We have examined these issues in a series of studies of (a) the early origins of emotional concern (empathy) and (b) the translation of concerned …
Limitations On Spatial Memory In Mice, Robert H.I. Dale, Martin Bedard
Limitations On Spatial Memory In Mice, Robert H.I. Dale, Martin Bedard
Scholarship and Professional Work - LAS
Rats have an impressive ability to remember locations they have visited. Two experiments used an eight-arm radial maze to determine whether mice showed two important characteristics of this spatial memory: its durability, and its dependence on stimuli outside the maze (extreme stimuli). In Experiment 1, food-deprived mice were allowed to eat from four of the eight arms of the maze then, after delays of 5 sec, 1 min, or 5 min, they were permitted to choose the remaining arms. Choice accuracy declined significantly with the longer delays, but always remained above chance. In Experiment 2, the maze was rotated 180° …
