In animal societies, behavioral idiosyncrasies of the individuals often guide which tasks theyshould perform. Such personality-specific task participation can increase individual task efficiency,thereby improving group performance. While several recent studies have documented group-levelbenefits of within-group behavioral （i.e., personality） diversity, how these benefits are realized atthe individual level is unclear. Here we probe the individual-level benefits of personality-driven taskparticipation in the social spider Stegodyphus dumicola. In S. dumicola, the presence of at leastone highly bold individual catalyzes foraging behavior in shy colony members, and all group con-stituents heavily compete for prey. We assessed boldness by examining how quickly spidersresumed normal movement after a simulated predator attack. We test here whether （1） participantsin collective foraging gain more mass from prey items and （2） whether bold individuals are less re-sistant to starvation than shy spiders, which would motivate the bold individuals to forage ***, we assembled colonies of shy spiders with and without a bold individual, added one preyitem, and then tracked the mass gain of each individual spider after this single feeding event. Wefound that spiders that participated in prey capture （whether bold or shy） gained more mass thannonparticipators, and colonies containing a single bold spider gained more total mass than purelyshy colonies. We also found that bold spiders participated in more collective foraging events andwere more susceptible to starvation than shy spiders, suggesting that the aggressive foraging ofbold individuals may represent a strategy to offset starvation risk. These findings add to the bodyof evidence that animal personality can shape social organization, individual performance, andgroup success.

Gastrointestinal cancer is a group of tumors that affect multiple sites of the digestive system, including the stomach, liver, colon and pancreas. These cancers are very aggressive and rapidly metastasize, thus identifying effective targets is crucial for treatment. Galectin-1(Gal-1) belongs to a family of glycan-binding proteins, or lectins, with the ability to cross-link specific glycoconjugates. A variety of biological activities have been attributed to Gal-1 at different steps of tumor progression. Herein, we summarize the current literature regarding the roles of Gal-1 in gastrointestinal malignancies. Accumulating evidence shows that Gal-1 is drastically up-regulated in human gastric cancer, hepatocellular carcinoma, colorectal cancer and pancreatic ductal adenocarcinoma tissues, both in tumor epithelial and tumor-associated stromal cells. Moreover, Gal-1 makes a crucial contribution to the pathogenesis of gastrointestinal malignancies, favoring tumor development, aggressiveness, metastasis, immunosuppression and angiogenesis. We also highlight that alterations in Gal-1-specific glycoepitopes may be relevant for gastrointestinal cancer progression. Despite the findings obtained so far, further functional studies are still required. Elucidating the precise molecular mechanisms modulated by Gal-1 underlying gastrointestinal tumor progression, might lead to the development of novel Gal-1-based diagnostic methods and/or therapies.
