Abstract Bighorn sheep (Ovis canadensis) management involves ecological and socioeconomic aspects, creating a social-ecological system (SES). Social-ecological thresholds can be identified in the system to assess its specific resilience in response to climate stressors. Thus, the aim of this study is to build a dynamic model to assess whether this system is resilient to a particular stressor (water stress). In this study, the SES is considered resilient if the bighorn population is sufficiently large to provide economic revenue to landowners and promote conservation action. We validate and formalize this model by conducting semistructured interviews to Bonfil ejido landowners located in Baja California Sur (BCS), Mexico, and to experts in the field of recreational hunting and wildlife management. To explore the changes in specific resilience in this SES, we conduct simulations to assess the impact of rainfall variability patterns on the system. Our results indicate that rainfall variations with respect to the historical record have the potential to disrupt both the species and the local economy and that the lack of adaptive capacity in both harvest and conservation strategies may affect the dynamics of the whole SES. Finally, this paper explores how adaptive wildlife conservation management strategies can enhance the resilience of both subsystems in this SES.

社会生态恢复力模型:墨西哥南下加利福尼亚州大角羊管理系统中的水分胁迫效应

摘要 大角羊(Ovis canadensis)管理涉及生态和社会经济方面,创建了一个社会生态系统(SES)。可以在系统中确定社会生态阈值,以评估其对气候压力源的具体适应能力。因此,本研究的目的是建立一个动态模型来评估该系统是否对特定压力源(水压力)具有弹性。在这项研究中,如果大角牛种群足够大,可以为土地所有者提供经济收入并促进保护行动,则认为 SES 具有弹性。我们通过对位于墨西哥南下加利福尼亚州 (BCS) 的 Bonfil ejido 土地所有者以及休闲狩猎和野生动物管理领域的专家进行半结构化访谈来验证和形式化该模型。为了探索该 SES 中特定弹性的变化,我们进行了模拟以评估降雨变化模式对系统的影响。我们的结果表明,相对于历史记录的降雨量变化有可能破坏物种和当地经济,并且在收获和保护策略方面缺乏适应能力可能会影响整个 SES 的动态。最后,本文探讨了适应性野生动物保护管理策略如何增强该 SES 中两个子系统的弹性。我们的结果表明,相对于历史记录的降雨量变化有可能破坏物种和当地经济,并且在收获和保护策略方面缺乏适应能力可能会影响整个 SES 的动态。最后,本文探讨了适应性野生动物保护管理策略如何增强该 SES 中两个子系统的弹性。我们的结果表明,相对于历史记录的降雨量变化有可能破坏物种和当地经济,并且在收获和保护策略方面缺乏适应能力可能会影响整个 SES 的动态。最后,本文探讨了适应性野生动物保护管理策略如何增强该 SES 中两个子系统的弹性。
