      Call synchrony has been reported for the snowy tree cricket (Oecanthus fultoni), but the degree to which it occurs in natural interactions has not been previously investigated. I recorded acoustic interactions among ten ...

    • Development of vegetation in wetlands restored on Ozaukee County Conservation Reserve Program Lands 

      Reinartz, James A; Warne, Elizabeth L (1990-10-01)
      We studied the natural revegetation of six wetlands created in 1988 and six wetlands created in 1989 in Ozaukee County, Wisconsin. By describing the flora and vegetation of these two sets of wetlands we could compare the ...
