Abstract

Life history of benthic faunas of tropical high-altitude cold environments are poorly studied. Here, monthly larval and adult data are presented for at Saltana Stream in Ecuador. In cold conditions throughout the year (6 °C), this species showed an asynchronous and continuous production. Larval density showed two peaks in August and April. All five larval instars were present in most months. Using the size-frequency method an annual rate of secondary production per biomass of 4.8 was calculated. The measured biomass was 785 mg/m.

摘要

热带高海拔寒冷环境底栖动物区系的生活史研究较少。在此，呈现了厄瓜多尔萨尔塔纳溪的月度幼虫和成虫数据。在全年寒冷的条件下（6摄氏度），该物种呈现出异步且持续的繁殖。幼虫密度在8月和4月出现两个峰值。大多数月份都有所有五个幼虫龄期。使用大小频率法计算出每生物量的年二次生产率为4.8。测得的生物量为785毫克/平方米。
