  Title When Is Self-Organization Used in Biological Systems? Type Journal Article
  Year 2002 Publication Biol Bull Abbreviated Journal (up) Biol Bull  
  Volume 202 Issue 3 Pages 314-318  
  Keywords  
  Abstract Self-organization, or decentralized control, is widespread in biological systems, including cells, organisms, and groups. It is not, however, the universal means of organization. I argue that a biological system will be self-organized when it possesses a large number of subunits, and these subunits lack either the communicational abilities or the computational abilities, or both, that are needed to implement centralized control. Such control requires a well informed and highly intelligent supervisor. I stress that the subunits in a self-organized system do not necessarily have low cognitive abilities. A lack of preadaptations for evolving a system-wide communication network can prevent the evolution of centralized control. Hence, sometimes even systems whose subunits possess high cognitive abilities will be self-organized. N1 -

  Title The Evolution of Political Intelligence: Simulation Results Type Journal Article
  Year 2002 Publication British Journal of Political Science Abbreviated Journal (up) Br. J. Polit. Sci.  
  Volume 32 Issue Pages 613-639  
  Keywords  
  Abstract Several bodies of theory develop the idea that the intelligence of highly social animals – most interestingly, humans is significantly organized around the adaptive problems posed by their sociality. By this “political intelligence” hypothesis, sociality selects for, among other attributes, capacities for “manipulating” information others can gather about one's own future behaviour, and for “mindreading” such manipulations by others. Yet we have little theory about how diverse parameters of the games that social animals play select for political intelligence. We begin to address that with an evolutionary simulation in which agents choose between playing Prisoner's Dilemma and Hawk-Dove games on the basis of the information they can retrieve about each other given four broad information processing capacities. We show that political intelligence – operationally, the aggregate of those four capacities evolves to its highest levels when co-operative games are generally more attractive than conflictual ones, but when conflictual games are at least sometimes also attractive.

  Title In search of king Solomon's ring: cognitive and communicative studies of Grey parrots (Psittacus erithacus) Type Journal Article
  Year 2002 Publication Brain, behavior and evolution Abbreviated Journal (up) Brain Behav Evol  
  Volume 59 Issue 1-2 Pages 54-67  
  Keywords *Animal Communication; Animals; Attention/physiology; Cognition/*physiology; Cues; Form Perception/physiology; Humans; Intelligence; Learning/physiology; Male; Models, Psychological; Parrots/*physiology; Psychomotor Performance/physiology; Reward; Social Behavior  
  Abstract During the past 24 years, I have used a modeling technique (M/R procedure) to train Grey parrots to use an allospecific code (English speech) referentially; I then use the code to test their cognitive abilities. The oldest bird, Alex, labels more than 50 different objects, 7 colors, 5 shapes, quantities to 6, 3 categories (color, shape, material) and uses 'no', 'come here', wanna go X' and 'want Y' (X and Y are appropriate location or item labels). He combines labels to identify, request, comment upon or refuse more than 100 items and to alter his environment. He processes queries to judge category, relative size, quantity, presence or absence of similarity/difference in attributes, and show label comprehension. He semantically separates labeling from requesting. He thus exhibits capacities once presumed limited to humans or nonhuman primates. Studies on this and other Greys show that parrots given training that lacks some aspect of input present in M/R protocols (reference, functionality, social interaction) fail to acquire referential English speech. Examining how input affects the extent to which parrots acquire an allospecific code may elucidate mechanisms of other forms of exceptional learning: learning unlikely in the normal course of development but that can occur under certain conditions.

  Title Convergence of complex cognitive abilities in cetaceans and primates Type Journal Article
  Year 2002 Publication Brain, Behavior and Evolution Abbreviated Journal (up) Brain Behav Evol  
  Volume 59 Issue 1-2 Pages 21-32  
  Keywords Animal Communication; Animals; Brain/physiology; Cerebral Cortex/physiology; Cetacea/*physiology; Cognition/*physiology; *Evolution; Humans; Intelligence; Primates/*physiology  
  Abstract What examples of convergence in higher-level complex cognitive characteristics exist in the animal kingdom? In this paper I will provide evidence that convergent intelligence has occurred in two distantly related mammalian taxa. One of these is the order Cetacea (dolphins, whales and porpoises) and the other is our own order Primates, and in particular the suborder anthropoid primates (monkeys, apes, and humans). Despite a deep evolutionary divergence, adaptation to physically dissimilar environments, and very different neuroanatomical organization, some primates and cetaceans show striking convergence in social behavior, artificial 'language' comprehension, and self-recognition ability. Taken together, these findings have important implications for understanding the generality and specificity of those processes that underlie cognition in different species and the nature of the evolution of intelligence.

  Title Song perception in the European starling: hemispheric specialisation and individual variations Type Journal Article
  Year 2002 Publication Comptes Rendus Biologies Abbreviated Journal (up) Compt. Rend. Biol.  
  Volume 325 Issue 3 Pages 197-204  
  Keywords lateralisation; perception; birdsong; starling; electrophysiology; individual variations; latéralisation; perception; chant; étourneaux; électrophysiologie; variations individuelles  
  Abstract Hemispheric specialisation for speech in humans has been well documented. The lateralisation for song production observed in songbirds is reminiscent of this hemispheric dominance. In order to investigate whether song perception is also lateralised, we made multiunit recordings of the neuronal activity in the field L of starlings during the presentation of species-specific and artificial non-specific sounds. We observed a systematic stronger activation in one hemisphere than in the other one during the playback of species-specific sounds, with inter-subject variability in the predominant hemisphere for song perception. Such an asymmetry was not observed for artificial non-specific sounds. Thus, our results suggest that, at least at the individual level, the two hemispheres of the starlings' brain perceive and process conspecific signals differently.

  Title An evaluation of long-term preservation methods for brown bear (Ursus arctos) faecal DNA samples Type Journal Article
  Year 2002 Publication Conservation Genetics Abbreviated Journal (up) Conservat. Genet.  
  Volume 3 Issue 4 Pages 435-440  
  Keywords  
  Abstract Relatively few large-scale faecal DNA studieshave been initiated due to difficulties inamplifying low quality and quantity DNAtemplate. To improve brown bear faecal DNA PCRamplification success rates and to determinepost collection sample longevity, fivepreservation methods were evaluated: 90%ethanol, DETs buffer, silica-dried, oven-driedstored at room temperature, and oven-driedstored at -20 °C. Preservationeffectiveness was evaluated for 50 faecalsamples by PCR amplification of a mitochondrialDNA (mtDNA) locus (~146 bp) and a nuclear DNA(nDNA) locus (~200 bp) at time points of oneweek, one month, three months and six months. Preservation method and storage timesignificantly impacted mtDNA and nDNAamplification success rates. For mtDNA, allpreservation methods had >= 75% success atone week, but storage time had a significantimpact on the effectiveness of the silicapreservation method. Ethanol preserved sampleshad the highest success rates for both mtDNA(86.5%) and nDNA (84%). Nuclear DNAamplification success rates ranged from 26-88%, and storage time had a significant impacton all methods but ethanol. Preservationmethod and storage time should be importantconsiderations for researchers planningprojects utilizing faecal DNA. We recommendpreservation of faecal samples in 90% ethanolwhen feasible, although when collecting inremote field conditions or for both DNA andhormone assays a dry collection method may beadvantageous.

  Title Leadership and Followership: Same Animal, Different Spots? Type Journal Article
  Year 2002 Publication Consulting Psychology Journal: Practice and Research Abbreviated Journal (up) Consult Psychol J Pract Res  
  Volume 54 Issue 3 Pages 157-165  
  Keywords  
  Abstract This study examined the relationship between the constructs of leadership, as operationalized through the Leadership Personality Survey (LPS; G.J. Curphy, 1998), and followership, as op-era-tion-al-iz-ed by the Power of Followership Survey (PFS; R.E. Kelley, 1992). The LPS is based on the 5-factor model of personality that is widely regarded as the premier model for understanding trait personality dimensions (R.R. McCrae & O.P. John, 1992). The PFS is based on R.E. Kelley's (1992) model of followership styles. Data were collected from 130 students at a military college as part of their involvement in an academic course on leadership. Correlational analyses revealed numerous significant positive relationships between these 2 constructs. Regression modeling provided insight into the relations of personality dimensions and followership. Limitations to this study and implications of these findings as well as future research directions are discussed.

  Title The use of fecal markers to facilitate sample collection in group-housed cats Type Journal Article
  Year 2002 Publication Contemporary Topics in Laboratory Animal Science / American Association for Laboratory Animal Science Abbreviated Journal (up) Contemp Top Lab Anim Sci

  Abstract The provision of proper social housing is a priority when designing an experiment using domestic cats as laboratory animals. When animals are group-housed, studies requiring analysis of stool samples from individual subjects pose difficulty in sample collection and identification. In this study, commercially available concentrated food colorings (known as bakers pastes) were used as fecal markers in group-housed cats. Cats readily consumed 0.5 ml of bakers paste food coloring once daily in canned cat food. Colorings served as fecal markers by imparting a distinct color to each cat s feces, allowing identification in the litter box. In addition, colored glitter (1/8 teaspoon in canned food) was fed to cats and found to be a reliable fecal marker. Long-term feeding of colorings and glitter was found to be safe and effective at yielding readily identifiable stools.
