概括

在跨境动物疾病 (TAD) 紧急情况期间,空中操作是屠杀野猪的最时间和成本高效的方法. 结合方法可以进一步提高野生猪种群控制的效率.

科学领域:

野生动物生态生态学
疾病生态学疾病生态学
虫害管理虫害管理虫害管理

背景情况:

野生动物的跨境动物病 (TAD) 对畜牧业贸易构成重大威胁,需要迅速制.
野生猪中的非洲猪瘟病毒 (ASFv) 是一个日益严重的全球问题,需要有效的应急应对策略.
关于各种野生猪杀方法对TAD反应的效率的数据有限.

研究的目的:

为了比较不同野生猪杀方法的时间和成本效益,以应对TAD紧急情况.
评估空中作业,捕捉,有毒诱和地面射击在杀和尸体回收率方面.
为未来涉及野猪的TAD反应提供资源分配和部署策略的信息.

主要方法:

在美国德克萨斯州中北部进行了为期两个月的实地研究,比较了四种杀方法:空中操作,捕捉,有毒诱和地面射击.
量化杀率,尸体回收,时间投资,以及与每种方法相关的成本.
基于人口减少指标计算的成本效益.

主要成果:

屠宰和尸体回收的整体平均率为0.15头野猪/人小时,为233.04美元/头野猪.
尽管初始投资很高,但空中作战对于减少人口的时间和成本效益最高 (减少10%的7266美元).
捕捉提供了立即的尸体恢复,但比空中行动慢13.5倍;有毒的诱和地面射击效率较低.

结论:

在紧急TAD应对场景中,空中操作是密集杀野生猪和尸体回收的最有效方法.
陷提供了一个有价值的替代品,当立即的尸体回收是至关重要的,虽然时间效率较低.
多种杀方法的战略整合可以优化涉及野猪的TAD反应的效率和准备.

关键词:

一个空中天线.非洲猪瘟是非洲猪瘟的一种疾病.消除消除消除野生猪是野生猪的一种.移除移除移除移除这就是Sus scrofa.有毒剂有毒剂陷陷是一个陷.带动物带动物野猪是野生猪的一种动物.

Conservation of Declining Populations

Conservation of Declining Populations

Conservation of declining population focuses on ways of detecting, diagnosing, and halting a population decline. The approach uses methods to prevent populations from going extinct.

Conservation of Small Populations

Conservation of Small Populations

Small population sizes put a species at extreme risk of extinction due to a lack of variation, and a consequent decrease in adaptability. This weakens the chances of survival under pressures such as climate change, competition from other species, or new diseases. Large populations are more likely to survive pressures such as these, as such populations are more likely to harbor individuals that have genetic variants that are adaptive under new stresses. Small populations are much less...
