assessment for seabirds. The role of refugia and growth centres. Biol. Conserv., 40(1):1-9.

Large spills adjacent to colonies of pursuit-diving seabirds could kill all birds at the colony. The rate of population recovery depends on the size and loca- tion of neighbouring colonies which may act as refugia or as growth centres that accelerate recovery

by attracting recruits. Population recovery following destruction of a major common murre Uria aalge colony in Newfoundland would likely be slow because of the absence of suitable refugia and growth centres near large colonies. Full assessment of recovery potential requires further information on inter-colony recruitment, movement of pre-breeders and their potential to repopulate a colony, dynamics of colony foundation, and the role of food compe- tition in determining colony size.

The LC50 and no-effect and 100% mortality con- centrations are reported from 96-hr and 10-day tests. The toxicity of contaminated sediments could be explained by chemical partitioning into overlying or interstitial water. Amphioxus is not recommended as a routine test species because of (1) difficulty in distinguishing severely affected from dead individ- uals, (2) inability to determine the status of bur- rowed animals without disrupting sediment, (3) their relative lack of sensitivity in acute exposures to toxic chemicals, and (4) difficulty in routine collection of sufficient numbers of animals. Grass shrimp, how- ever, are useful as an epibenthic test species for waterborne and sediment-source toxicants. US EPA Environ. Res. Lab., Gulf Breeze, FL 32561, USA.
