| Title | Assessing How Fish Predation and Interspecific Prey Competition Influence a Crayfish Assemblage |
| Creator | Garvey, James E. Stein, Roy A. Thomas, Heather M. |
| Description | In northern Wisconsin lakes, the introduced crayfish Orconectes rusticus is replacing O. propinquus, a previous invader, and O. virilis, a native crayfish. Herein, we explore how fish predation and competition interact to drive this change in crayfish species composition. In outside pools, we conducted selective predation experiments exposing crayfish to largemouth bass, Micropterus salmoides, to quantify patterns of crayfish vulnerability. To determine how interactions among crayfish... |
