✦ Synopsis

The effect of temperature on the life history of various representatives of the meiofauna associated with decaying mangrove (Rhizophora mangle) leaves was investigated. Life cycles, recorded in days, for 6 species of marine nematodes cultured at a temperature of 24 ~ are as follows: Rhabditis marina, 2 ~ /4 ; Di plolaimelloides sp.,7; Diplolaimella ocetlata,l 11/ 2 ; Enoplus paralittoralis, 22; Oncholaimus sp., 29; Halipleetus dorsalis, 34. In general, life cycles become shorter with increased temperatures; however, as temperatures approach the upper limits which support reproduction, life cycles become slightly lengthened. For most species, the ability to complete a life cycle was inconsistent within the temperature range of 33 ~ to 35 ~ Studies with two harpaeticoid copepod and two foraminifera species tend to support the 33 ~ to 35 ~ range as being the thermal stress zone.
