Effect of crab effluent on lobster interactions

We exposed two different size classes of juvenile lobsters (Homarus americanus) to either control seawater or seawater with green crab (Carcinus maenas) effluent. This was done in arenas in the lab, with one shelter available and two lobsters in the tank at once. The process was recorded with time-lapse photographs (0.5s) and then aggression and shelter use were quantified. You can read the manuscript for additional detail.

本研究将两个不同体型分级的美洲螯龙虾幼体（Homarus americanus）分别暴露于对照海水与添加欧洲绿蟹（Carcinus maenas）排泄液的海水环境中。实验于实验室的饲养槽内开展，每个槽内配备一处遮蔽物，且单次同时放置两只龙虾。实验过程通过间隔0.5秒的延时摄影照片（time-lapse photographs）进行记录，随后对龙虾的攻击行为与遮蔽物占用情况进行量化分析。更多详细信息可参阅该研究手稿。
