    Inbreeding depression in the convict cichlid, Cichlasoma nigrofasciatum (Baird and Girard) (1982)
    Oxford, UK : Blackwell Publishing Ltd
    Journal of fish biology 21 (1982), S. 0 
    Details
    ISSN: 1095-8649
    Source: Blackwell Publishing Journal Backfiles 1879-2005
    Topics: Biology
    Notes: Convict cichlids, Cichlasoma nigrofasciatum, inbred for four and five generations exhibited moderate and severe morphological deformities. Deformed fishes were characterized by a more vertically sloping forehead, irregular jaw, hyoid, opercula and fin structure, reduced growth and irregular swimming behaviour. Inbred fish (F4, F5) did not differ from F1s in their age of maturation or the average size of their first broods. Brood survival was 18.7% in F5 inbred fish, compared to 75.5% in F1s.

    Notes: [Auszug] With the emergence of models of latency based on stochastic processes3, the importance of the average latency declines somewhat, since the average value of a probability distribution has no uniquely valuable properties. Indeed, as a sole measure, it may be almost useless. Reaction times are ...

    Two methods for using period length to study rhythmic phenomena (1973)
    Springer

    Notes: Summary We have developed two distinct methods of biological rhythm analysis. The procedures are based on existing techniques for analysis of time series, Enright's periodogram and autocorrelation, and both of the new methods use the parameter, period length (τ), for defining oscillatory phenomena. We empirically evaluated the two types of analyses using real biological data from circadian rhythm studies in salamanders and sparrows. The first method permits us to make a statistical comparison of period lengths between groups of animals in given treatments. This method is useful for data where the signal-to-noise ratio of the suspected rhythm is very low; and the method is not adequate for making a definitive judgment from single animals. It can best be applied to the question of whether a signal is entraining a rhythm or not and to questions of group differences in period length. With the second method, we determined period length versus time. Using this procedure, we took into consideration the observation that the period length of many biological oscillations changes with time. The method is applicable to records from individual animals, and it can be used to compare treatment effects in individual animals. The technique can also be used to answer the common question of whether periodicityper se exists within a defined range in a time series.

    Latency models for reaction time distributions (1965)

    Notes: Abstract This paper presents an adaptation of the method of moments for comparing observed and theoretical distributions of reaction time. By using cumulants in place of moments, considerable simplification of the treatment of convoluted distributions is obtained, particularly if one of the components is normally distributed. Stochastic latency models are often poorly fitted by reaction time data. This may be because a simple latency distribution is convoluted with a normal or high-order gamma distribution. The comparison method described will assist investigation of this and other interpretations of reaction time distributions.
