    abstract = {The seasonal patterns of rotifer community structure in response 
  to temporal fluctuations in environmental variables were investigated in two 
  water bodies located in Northwest Iran. Sampling was carried out during October 
  2007 to November 2008. In total, 45 rotifer species were identified from the 
  two studied sites. In each site, rotifer species diversity differed seasonally. 
  Temporal patterns observed innon-metric Multidimensional Scaling (nMDS) ordinationsrevealed 
  separation of Summer from other seasons due to different diversity and density 
  of the rotifer assemblages. Analysis of Variance (ANOVA) also showed significant 
  difference in the rotifer diversity and abundance among seasons (F = 4.7, p&lt;0.05). 
  Rotifer species diversity was highly correlatedwith the level of dissolved oxygen 
  and pH in the reservoir Cheshmehgul (r = 0.92 and 0.63, respectively, p&lt;0.001). 
  However, analysis of the accumulated data of both water bodies revealed that 
  a significant Spearman=s correlation coefficient existed between salinity and 
  water temperature and the abundance of the rotifers (r = 0.54, p&lt;0.001). 
  Canonical Correspondence Analysis (CCA) identified dissolved oxygen and electrical 
  conductivity to be the main environmental factors shaping the rotifer assemblages. 
  According to this study, seasonal variations in environmental factors can influence 
  structure of rotifer communities even in distinct, unrelated ecosystems.}
