摘要
An analysis of living and dead components of a population of deep-sea agglutinated Foraminifera reveals that both segments of the fauna are dispersed nonrandomly on a scale of centimeters. Significant positive correlations between the distribution of living and dead individuals in several species imply that small-scale patch structure in this environment may persist for more than one generation. Mechanisms maintaining such structure may include habitat selection and reproductive patterns and suggest that dispersion pattern is the result of an active interaction between amimals and a heterogeneous physical and biotic environment. © 1979 Springer-Verlag.
