    Title
    A Study Of The Relationship Between Preferred Temperature Selection And Ontogeny In The Guppy, Lebistes reticulatus
    Type
    thesis
    Abstract
    The relationships between preferred temperature and ontogeny in the guppy Lebistes reticulatus were investigated using a horizontal temperature gradient. The results suggest a preference for warmer temperatures in the juvenile fish. It appears there is a gradual shift in selection from warmer to cooler temperatures as the guppy matures to the adult stage. This higher temperature preference in the younger fish may be related to optimum growth rate and avoidance of predation especially from its own species. Predation experiments were also run in the gradient. No definite conclusions about the relationship between predation and temperature selection could be made from the data.
