The partitioning of energy in three species of nematode, Paroigolaimella bernensis, Diplogasteritus nudicapitatus and Rhabditis curvicaudata, from a polysaprobic environment is considered. Temperature was shown to have a profound impact on the rate at which these organisms obtained food resources and on the partitioning of energy into growth, reproduction and maintenance. Declining temperature resulted in a reduction in energy consumption and in production and maintenance costs. Absorption efficiencies were relatively low, rarely exceeding 20% and lying on average between 5-15%. Net production efficiencies varied throughout the life-cycle, but attained maximum levels of 70-80%. Females achieved higher net production efficiency than males. The physiology and ecological implications are discussed.
本文考虑了来自多污带环境的三种线虫，即伯氏拟奥戈线虫、裸头双胃线虫和弯尾小杆线虫的能量分配情况。结果表明，温度对这些生物获取食物资源的速率以及能量在生长、繁殖和维持之间的分配有着深远影响。温度下降导致能量消耗以及生产和维持成本降低。吸收效率相对较低，很少超过20%，平均在5%-15%之间。净生产效率在整个生命周期中有所变化，但最高可达70%-80%。雌性的净生产效率高于雄性。文中还讨论了其生理学和生态学意义。
