Abstract

Effective, practical options for managing disease in wildlife populations are limited, especially after diseases become established. Removal strategies (e.g., hunting or culling) are used to control wildlife diseases across a wide range of systems, despite conflicting evidence of their effectiveness. This is especially true for chronic wasting disease (CWD), an untreatable, fatal prion disease threatening cervid populations across multiple countries, for which recreational harvest has been suggested as an important disease control strategy. Using observational data to evaluate whether harvest effectively limits CWD prevalence has been difficult because statistical relationships between harvest and disease prevalence can arise from a causal effect of harvest (i.e., harvest's impacts on prevalence via changes in transmission or demographic structure) or from a number of alternative mechanisms. For instance, correlations between harvest and disease prevalence can also be driven by disease's impacts on population size and harvest (i.e., reverse causality) or from confounding variables (e.g., habitat or geographic location) that impact both harvest rates and disease prevalence. We analyzed two decades of surveillance data (2000–2021) from 10 mule deer herds in Wyoming, using statistical approaches informed by causal inference theory, to test for the effects of harvest on CWD prevalence. Herds with consistently high harvest pressure across 20 years had significantly lower prevalence. Our models predicted that harvesting 40% of adult males per year across 20 years would maintain prevalence below 5% on average, whereas if only 20% of males were harvested in each year, prevalence would increase to >30% by year 20. Moreover, shifting the relative harvest pressure within a herd over a shorter period (3 years) reduced subsequent prevalence, albeit to a smaller degree. Although high harvest is unlikely to completely eradicate CWD, our analysis suggests that maintaining hunting pressure on adult males is an important tactic for slowing CWD epidemics within mule deer herds. Our study also provides guidance for future analyses of longitudinal surveillance data, including the importance of demographic data and appropriate time lags.

收获对限制野生动物疾病的有效性:来自怀俄明州20年慢性消耗性疾病的见解
在野生动物种群中管理疾病的有效、实际的选择有限,特别是在疾病已经确定之后。清除策略(例如狩猎或扑杀)用于在广泛的系统中控制野生动物疾病,尽管有关其有效性的证据相互矛盾。对于慢性消耗性疾病(CWD)尤其如此,这是一种无法治疗的致命朊病毒疾病,威胁着多个国家的宫颈种群,娱乐性收获已被建议作为一种重要的疾病控制策略。利用观测数据来评估采收是否有效地限制了CWD的流行一直很困难,因为采收与疾病流行之间的统计关系可能源于采收的因果效应(即,采收通过传播或人口结构的变化对流行的影响)或一些替代机制。例如,收获与疾病流行之间的相关性也可由疾病对种群规模和收获的影响(即反向因果关系)或影响收获率和疾病流行的混杂变量(例如生境或地理位置)驱动。我们分析了怀俄明州10个骡鹿群20年(2000-2021年)的监测数据,使用因果推理理论的统计方法来测试收获对CWD流行的影响。在过去20年中,收获压力持续较高的畜群的流行率显著降低。我们的模型预测,在20年内每年捕获40%的成年雄性,将使患病率保持在5%以下,而如果每年只捕获20%的雄性,到20年患病率将增加到30%。此外,在较短的时间内(3年)改变畜群内的相对收获压力,减少了随后的流行,尽管程度较小。虽然高收成不太可能完全根除CWD,但我们的分析表明,维持成年雄鹿的狩猎压力是减缓CWD在骡鹿群中流行的重要策略。我们的研究还为纵向监测数据的未来分析提供了指导,包括人口统计数据的重要性和适当的时间滞后。

期刊介绍: The pages of Ecological Applications are open to research and discussion papers that integrate ecological science and concepts with their application and implications. Of special interest are papers that develop the basic scientific principles on which environmental decision-making should rest, and those that discuss the application of ecological concepts to environmental problem solving, policy, and management. Papers that deal explicitly with policy matters are welcome. Interdisciplinary approaches are encouraged, as are short communications on emerging environmental challenges.
