保护行为干预的有效性往往取决于当地资源使用者的潜在社会互动。然而，目前尚不清楚资源使用者之间共享的相关信息主题的差异在多大程度上可以改变网络结构对信息流和行为传播的影响。在这里，我们探讨了与计划扩大社区共同管理计划有关的渔业信息的九个子主题的差异，该计划旨在减少秘鲁小规模渔业的海龟附带捕捞。研究表明，海龟副渔获信息共享的一般网络结构不同于其他渔业信息共享。具体来说，没有发现显著的度同性（度同源性），节点偏心的方差低于我们的零模型下的预期。我们还表明，渔民之间与海龟副渔获物相关的信息共享模式更类似于捕捞法规、船舶技术和维护方面的信息共享，而不是天气、捕捞活动、财务和船员管理方面的信息共享。我们的研究结果强调了在与预期干预直接相关的环境中评估信息共享网络的重要性，并证明了识别可能或多或少适合与计划保护行动相关的信息共享的社会环境。
The effectiveness of behavioural interventions in conservation often depends on local resource users' underlying social interactions. However, it remains unclear to what extent differences in related topics of information shared between resource users can alter network structure—holding implications for information flows and the spread of behaviours. Here, we explore the differences in nine subtopics of fishing information related to the planned expansion of a community co-management scheme aiming to reduce sea turtle bycatch at a small-scale fishery in Peru. We show that the general network structure detailing information sharing about sea turtle bycatch is dissimilar from other fishing information sharing. Specifically, no significant degree assortativity (degree homophily) was identified, and the variance in node eccentricity was lower than expected under our null models. We also demonstrate that patterns of information sharing between fishers related to sea turtle bycatch are more similar to information sharing about fishing regulations, and vessel technology and maintenance, than to information sharing about weather, fishing activity, finances and crew management. Our findings highlight the importance of assessing information-sharing networks in contexts directly relevant to the desired intervention and demonstrate the identification of social contexts that might be more or less appropriate for information sharing related to planned conservation actions.
