In a.ima. societies, beha.iora. idiosyncra.ies of the individua.s often guide which ta.ks theyshould perform. Such persona.ity-specific ta.k pa.ticipa.ion ca. increa.e individua. ta.k efficiency,thereby improving group performa.ce. While severa. recent studies ha.e documented group-levelbenefits of within-group beha.iora. （i.e., persona.ity） diversity, how these benefits a.e rea.ized a.the individua. level is unclea.. Here we probe the individua.-level benefits of persona.ity-driven ta.kpa.ticipa.ion in the socia. spider Stegodyphus dumicola. In S. dumicola. the presence of a. lea.tone highly bold individua. ca.a.yzes fora.ing beha.ior in shy colony members, a.d a.l group con-stituents hea.ily compete for prey. We a.sessed boldness by exa.ining how quickly spidersresumed norma. movement a.ter a.simula.ed preda.or a.ta.k. We test here whether （1） pa.ticipa.tsin collective fora.ing ga.n more ma.s from prey items a.d （2） whether bold individua.s a.e less re-sista.t to sta.va.ion tha. shy spiders, which would motiva.e the bold individua.s to fora.e ***, we a.sembled colonies of shy spiders with a.d without a.bold individua., a.ded one preyitem, a.d then tra.ked the ma.s ga.n of ea.h individua. spider a.ter this single feeding event.

近年来,半导体催化剂因其较强的氧化还原能力和较好的稳定性而受到广泛关注.然而,光生电子和空穴对易复合和低氧化性导致单一半导体催化剂难以实现实际应用.深入研究表明,S型异质结具有独特的电子和空穴分离机理、强大的氧化还原能力和较强的载流子分离驱动力.本研究以在In_(2)O_(3)纳米球上生长的Bi_(19)Br_(3)S_(27)纳米花为原料,采用水热法合成了In_(2)O_(3)/Bi_(19)Br_(3)S_(27)梯形异质结.这种梯形异质结有效地促进了光生电荷载流子的分离和转移.结果表明,In_(2)O_(3)/Bi_(19)Br_(3)S_(27)复合材料对CO_(2)的还原产率高达28.36μmol h^(-1)g^(-1),分别是In_(2)O_(3)和Bi_(19)Br_(3)S_(27)的19和3.5倍.此外,通过原位漫反射红外傅里叶变换光谱对参与光催化反应的中间体进行了研究,揭示了光催化还原CO_(2)的反应过程.本工作为构建S型异质结光催化剂增强CO_(2)催化还原的方法提供了较好的研究思路.
