前言根据有关资料介绍,野生动物布病的传染源可成为家畜布病的来源。例如欧洲野兔中流行的猪布病第3生物型能使猪体受到传染。感染布病的野生动物和鼠类,可经其体表寄生的扁虱而使家畜受到感染。由于布氏杆菌在扁虱体内繁殖,存活的时间较长,可以长期保持对家畜的致病力。感染布病的野生的鼠、兔等在家畜布病的传播上,具有一定的作用。因此,在草原上防治布病在家畜中的传播中,研究布病对野生动物的感染情况也是一个重要的环节。为此 ...

野猪春季农耕觅食地选择特征初探——以贵州赤水桫椤国家级自然保护区为例
为了研究野猪(Sus scrofa)春季农耕觅食地生境选择特征,以贵州赤水桫椤国家级自然保护区为例,于2015~2016年春季,利用样方调查法在保护区内对野猪危害的农耕地开展实地调查。主成分分析结果表明,特征值大于1的共有4个主成分,累计贡献率为67.56%,包括隐蔽因素、可视度因素、人为干扰因素和农耕地因素。野猪在利用农耕地觅食时,倾向于选择灌木和农作物盖度较大(隐蔽因素)、灌木和乔木较高(可视度因素)以及远离居民点的区域(人为干扰因素),并且,野猪选取的农耕地食物资源较丰富,外形呈狭长型 ...

The mass mortality of Asia's native pigs induced by African swine fever 非洲猪瘟引起亚洲本土猪大规模死亡
Most Asian wild pigs (Sus scrofa) in a Peninsular Malaysian primary rainforest died within a 6‐week period in May–June 2022. Abstract Asia's wild pigs are ecosystem engineers and a key food for predators and people. The arrival of African swine fever (ASF) in 2018 induced near‐100% fatality in domestic pigs and decimated the Chinese pork industry in ...

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响
This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

This study establishes the optimal nonlethal laser deterrence range (210–260 W, 1s) for wild boars, preventing agricultural damage while ensuring animal safety. Results demonstrate that efficacy requires seasonal power adjustments (≤ 285 W in winter) and precise targeting control—enabling effective, injury‐free wildlife conflict mitigation.

Wildlife mortality risk posed by high and low traffic roads
Abstract Wildlife mortality due to collisions with vehicles (roadkill) is one of the predominant negative effects exerted by roads on many wildlife species. Reducing roadkill is therefore a major component of wildlife conservation. Roadkill is affected by various factors, including road attributes and traffic volume.

《野猪渡河》是张贵兴以三年零八个月的日据时期下的时代背景而展开述说的砂华史。由于《野猪渡河》仅出版将近两年之久,所以并未有太多的学者对其进行研究。因此本论文将探讨张贵兴在《野猪渡河》的面具书写和蕴涵研究,面具书写分为四个不同的面向:象征权力面具的日军、象征欲望面具的朱大帝、以及爱蜜莉戴上面具以伪装自己的真实身份,和马婆婆用面具来作为她的保护色。而面具的蕴含就分为暴力和人性两个课题。本论文会先运用叶芝的“面具理论”来分析张贵兴在《野猪渡河》里所创造的第二自我——既文本中的丑角 ...

近年来,以野猪为代表的野生动物与人冲突事件频发,不仅造成了经济损失,甚至人员伤亡,而且也不利于维护生态平衡。成为社会关注的热点。冲突主要体现在破坏庄稼、伤害人畜、传播疾病等,导致受害者对野猪的忍耐性降低、反对野猪保护。本文综述了野猪与人冲突的表现、原因及防控策略的效果。
