    Notes: [Auszug] Fig. l The possible outcomes when individuals settle out at random from a pool of n competitors to fill patches with 6 resource units. In one patch competitors consist of n -1 individuals who play Xp = 2, and a single mutant individual who plays Xm = 3. In the remaining P-l patches all competitors ...

    Notes: [Auszug] The science of sociobiology, which began in principle with the work of Fisher and Haldane and has more recently been developed by Hamilton, Maynard Smith, Trivers, Wilson and others, has been the centre of both scientific and political controversy. Dr Parker discusses the strengths and weaknesses ...

    Male mate choice as predicted by sperm competition in thirteen-lined ground squirrels (1990)
    [s.l.] : Nature Publishing Group
    Nature 348 (1990), S. 62-64 
    Details
    ISSN: 1476-4687

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] In many polygynous species, male reproductive success hinges primarily on fertilizations achieved per unit time invested11. For male thirteen-lined ground squirrels, pay-offs from mating can vary markedly owing to sperm competition. Oestrous females commonly mate with any males that find them and ...

    Optimality theory in evolutionary biology (1990)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Optimization models help us to test our insight into the biological constraints that influence the outcome of evolution. They serve to improve our understanding about adaptations, rather than to demonstrate that natural selection produces optimal ...

    Notes: [Auszug] FIELD studies of the long-tailed widow-bird, Euplectes progne, by Andersson1 involved experimental manipulation of the tail-lengths of territorial males and measurement of their breeding success in terms of the number of females that nested in the male's territory. The Darwin-Fisher theory2'3 of ...

    Punishment in animal societies (1995)

    Topics: Biology , Chemistry and Pharmacology , Medicine , Natural Sciences in General , Physics
    Notes: [Auszug] Although positive reciprocity (reciprocal altruism) has been a focus of interest in evolutionary biology, negative reciprocity (retaliatory infliction of fitness reduction) has been largely ignored. In social animals, retaliatory aggression is common, individuals often punish other group members ...

    Notes: [Auszug] LIBIDINOUS females? On page 440 of this issue1, Madsen et al. present new evidence why we may expect them to be so. The evidence and its interpretation is intriguing, not least because it runs counter to the longstanding view that, whereas males should be eagerly promiscuous, females, once ...

    Evolution of phenotypic optima and copula duration in dungflies (1994)

    Notes: [Auszug] The reproductive behaviour of dungflies, Scatophaga stercoraria, has been widely analysed using ideal free10'11 and marginal value models12'13 in behavioural ecology. Dungfly males arrive quickly at fresh cattle droppings and copulate when they capture incoming gravid females. Females contain sperm ...
