Abstract
Energy flow A = R + P assimilation = respiration + production and lifehistory/densitybiomass cycles were followed for 1 year in a mayfly Brachycercus sp population and two chironomid Procladius sp and Tendipes decorus populations in a 094 ha pond located in northcentral Texas Temperature 5 10 15 20 25 and 30°C effects on R and patterns of metabolic compensation/acclimatization were determined for the mayfly and chironomids Chironomid and mayfly populations dominated the nine benthic macroinvertebrates identified in the pond with greatest abundances in winter and winterspring respectively Annual energy flow was 51 kcal m−2 R = 40 kcal P = 11 kcal or 19 g in Brachycercus sp 23 kcal m−2 R = 5 kcal P = 18 kcal or 24 g in Procladius sp and 74 kcal m−2 R = 17 kcal P = 57 kcal or 60 g in T decorus Each species metabolically compensated partially to temperatures en countered during their life histories
