POST-EMBRYONIC GROWTH OF THE COLLEMBOLANS FOLSOMIA CANDIDA AND XENYLLA GRISEA AT THREE TEMPERATURES

Abstract

AbstractThe relationship between body size and age in two species of Collembola, Folsomia Candida and Xenylla grisea, was studied in three temperature regimes. Power curves were used to describe length as a function of age for each species-temperature combination. Growth parameters (slopes of the log-log curves) and length at hatch (log intercepts) were compared by multiple regression. There was a strong non-linear effect of temperature on growth in the range normally encountered.
