Rotifer diversity in a central Mexican pond

Abstract

A survey of rotifers from a small pond (less than 2 ha in area and 3 m deep), located at Kilometer 28 in the federal highway Ixtlahuaca-Jilotepec (19°49' 13'' N, 99°42' 22'' W) at an altitude of 2503 m above sea level, resulted in a total of 78 species. From these, 20 are new records for Mexico. This study confirms the presence of some of the rotifer species listed only in earlier studies. Comments on some species are made from a zoogeographical point of view.
