Social deprivation early in life affects further individual development and leads to irreversible behavioural alterations later in life. Although the syndrome is well-studied in vertebrates including humans, its presence in invertebrates has been described only in eusocial insects and cockroaches. Here we show the first evidence of social deprivation in subsocial decapod crustaceans, based on analysis of video-recorded agonistic encounters of juvenile red swamp crayfish (Procambarus clarkii, Girard). In comparison with maternally incubated juveniles, isolated crayfish had altered repertoires, numbers and frequency of agonistic interactions similar to those described in vertebrates. Our results support the view on the syndrome of social deprivation as a ubiquitous trait in species with developed maternal care across diverse taxa.
社会剥夺在生命早期会影响进一步的个体发展，并导致生命后期不可逆转的行为改变。尽管这种综合征在包括人类在内的脊椎动物中得到了很好的研究，但在无脊椎动物中，仅在社会性昆虫和蟑螂中有所描述。在这里，我们基于对幼年红沼泽小龙虾（Procambarus clarkii，Girard）的攻击性遭遇的视频记录分析，展示了在亚社会性十足甲壳动物中社会剥夺的第一个证据。与母体孵化的幼体相比，孤立的小龙虾表现出改变的行为模式、数量和频率的攻击性相互作用，类似于在脊椎动物中描述的那样。我们的结果支持了社会剥夺综合征作为一种普遍特征的观点，即在具有发达的母性照顾的物种中跨越不同的分类群。
