Abstract

Local ecological knowledge (LEK) has been increasingly used in the search for efficient strategies to maintain biological diversity. However, considering the rapid environmental changes in ecosystems, such knowledge may have been lost between generations, affecting its potential application. In this study, we adopted the LEK of the potential dispersers of Caryocar coriaceum Wittm. (Caryocaraceae), an endangered plant species of socioeconomic and cultural importance from northeast Brazil, as a model. We evaluated whether there is intergenerational variation in the LEK about the abundance of Dasyprocta prymnolopha (the principal disperser of C. coriaceum) associated with the local practice of hunting. We collected LEK data from 39 hunter-gatherers aged 31 to 84 years, and camera traps were used during two annual C. coriaceum harvests to record its potential dispersers. Our results indicate that the LEK of the potential animal dispersers of C. coriaceum does not vary between generations; it is disseminated and shared between different generations. The strong interactions among people during the C. coriaceum harvest period facilitate the sharing of information about the potential dispersers of this species. Our results show that hunting D. prymnolopha does not depend on perceptions regarding the availability of this resource in the forest, which may be causing overexploitation. Therefore, local knowledge may need to be updated and connected to the recent and rapid environmental changes because people may believe that current environmental conditions are like those of the past. If this is the case, people may be less cooperative with conservation strategies because they are not aware of environmental changes, so measures to update knowledge about environmental conditions may be necessary to encourage effective participation in management and conservation plans.

人们将有关环境的生态信息社会化，却可能忘记自己的经验：有关种子传播动物的地方生态知识的案例研究

当地生态知识（LEK）已被越来越多地用于寻找维护生物多样性的有效策略。然而，考虑到生态系统中环境的快速变化，这些知识可能已经在代际之间丢失，影响了其潜在的应用。在本研究中，我们采用了 Caryocar coriaceum Wittm.(Caryocaraceae）的潜在散布者（LEK）为模型，该物种是巴西东北部具有社会经济和文化重要性的濒危植物物种。我们评估了关于 Dasyprocta prymnolopha（C. coriaceum 的主要传播者）丰度的 LEK 是否存在与当地狩猎活动相关的代际差异。我们收集了 39 位年龄在 31 至 84 岁之间的狩猎采集者的 LEK 数据，并在每年的两次 C. coriaceum 收获期间使用相机陷阱记录其潜在的传播者。我们的研究结果表明，矢车菊潜在动物散布者的低密度脂蛋白钾（LEK）在不同世代之间并无差异；它在不同世代之间传播和共享。在鸡冠花收获期，人与人之间的强烈互动促进了有关该物种潜在散布者的信息共享。我们的研究结果表明，狩猎 D. prymnolopha 并不取决于对森林中该资源可用性的认识，这可能会导致过度开发。因此，当地的知识可能需要更新，并与近期快速的环境变化联系起来，因为人们可能认为当前的环境条件与过去一样。如果是这种情况，人们可能会因为不了解环境变化而不太配合保护战略，因此可能需要采取措施更新有关环境条件的知识，以鼓励有效参与管理和保护计划。

期刊介绍： Ethnobiology and Conservation (EC) is an open access and peer-reviewed online journal that publishes original contributions in all fields of ethnobiology and conservation of nature. The scope of EC includes traditional ecological knowledge, human ecology, ethnoecology, ethnopharmacology, ecological anthropology, and history and philosophy of science. Contributions in the area of conservation of nature can involve studies that are normally in the field of traditional ecological studies, as well as in animal and plant biology, ethology, biogeography, management of fauna and flora, and ethical and legal aspects about the conservation of biodiversity. However, all papers should focus explicitly on their contribution to the conservation of nature. Merely descriptive papers without a theoretical discussion contextualized from the findings, although possibly being accepted, will not be given priority for publication.
