Microcystin-LR (one of the toxic congeners of microcystin) exposure causes crayfish to forget previous fight outcomes as well as previous opponents, MI, 2025

Harmful algal blooms are increasing across the globe as a function of nutrient run off and climate change. While the study of the mechanisms that underlie the blooms themselves are abundant, the impact of the toxins produced by blooms needs more research. Crayfish are keystone species in aquatic habitats and rely on chemoreception for many of their ecosystem functions. Crayfish were placed in a fight arena for measure both the outcome and dynamics aspects of agonistic encounters. Then the loser of the fights were exposed to either controls or microcystin for four days. Afterwards, the crayfish fought either another unfamiliar opponent or the previous opponent. The data contained in this package has the concentrations of microcystin exposure, morphological data on the crayfish, and then behavioral data from the two different fights. The behavioral data has two categories: time spent at different levels of intensity and time it took the crayfish pair to reach a certain intensity.

随着营养盐径流与气候变化的影响，全球有害藻华的发生规模正持续扩大。尽管针对藻华自身形成机制的研究已较为丰富，但藻华产生的毒素所带来的生态影响仍有待更多深入探索。淡水小龙虾是水生生境中的关键物种，其诸多生态功能均依赖化学感应机制完成。研究人员将淡水小龙虾置于争斗竞技场中，以测定其争斗交锋的结局与动态特征。随后，将争斗中的败虾分别暴露于对照组环境或微囊藻毒素（microcystin）环境中，持续时长为4天。之后，让这些败虾分别与陌生同类或此前的争斗对手再次进行争斗。本数据集套件包含以下三类数据：微囊藻毒素暴露浓度数据、淡水小龙虾形态学数据，以及两次不同争斗场景下的行为学数据。其中行为学数据包含两个类别：不同争斗强度等级下的停留时长，以及该对小龙虾达成特定争斗强度所需的耗时。
