Although the plants themselves make study difficult, they structure the habitat in interesting ways, and examination of these places can provide insight to ecological processes such as community structure, especially for small metazoans such as rotifers. For example, macrophytes provide interstices for concealment from visual predators and offer spatial and temporal variability of microcimate, including oxygen concentration, pH, and temperature (Dvorak 1970, Vitt & Bayley 1984). Moreover, rotifers have their greatest diversity in the littoral (Pennak 1966, Wallace et al. 2006). Rotifer abundance and diversity is high in the littoral, yet few studies have focused on their community structure in macrophyte dominated systems.We examined the spatial and temporal diversity of a rotifer community in a backwater near the River Tisza, comprising a diverse vegetation complex of marsh, emerged, and submerged macrophytes. 收起
