 of temperatures and landings (heads-off) of pink shrimp 

 Penaetis diiorarum. Open circles represent years before 1982 

 reported by Hettler and Chester (1982); closed circles repre- 

 sent the years 1982-91. (Bottom) Spring landings (heads-off)

 availability of habitats that respond differently to drop- 

 ping temperatures. The safest habitats would include 

 favorable sediments for deep burrowing, deep water, 

 and physiologically isosmotic salinity.
