概括

慢性衰竭疾病 (CWD) 并没有显著改变白尾鹿 (WTD) 削行为. 然而,年和白天光的人口水平变化表明CWD对生殖策略的潜在影响.

科学领域:

野生动物生态生态学
动物行为动物行为
疾病生态学疾病生态学

背景情况:

野生动物疾病的爆发可能会导致人口通过死亡率或行为变化减少健康状况而下降.
慢性衰竭疾病 (CWD) 是一种影响子宫的神经病原体,已知会影响行为和运动.

研究的目的:

调查CWD对白尾鹿 (Odocoileus virginianus; WTD) 生殖行为的影响,特别是削.
为了确定CWD状态是否会影响削交互的频率或类型.

主要方法:

监测在一个高CWD流行率的地区的107个削地点.
摄像机陷记录了3,063次抓取互动,涉及218只独特的鹿 (雄鹿,鹿,小鹿).
从削场所收获的公牛 (13个阳性,8个阴性) 中CWD状态的分析.

主要成果:

没有发现CWD状态对个人皮行为有显著影响.
子占了大部分的擦除互动 (73%).
观察到潜在的人口水平的变化:与以前的研究相比,年龄大的雄鹿在白天和白天的削比例增加.

结论:

在这项研究中,CWD没有明显改变个体WTD削行为.
观察到的人口层面上削模式的变化可能表明CWD对WTD生殖策略的间接影响.
需要进一步的研究来了解CWD在鹿类种群中的更广泛的生态和行为后果.

Threats to Biodiversity

Threats to Biodiversity

There have been five major extinction events throughout geological history, resulting in the elimination of biodiversity, followed by a rebound of species that adapted to the new conditions. In the current geological epoch, the Holocene, there is a sixth extinction event in progress. This mass extinction has been attributed to human activities and is thus provisionally called the Anthropocene. In 2019 the human population reached 7.7 billion people and is projected to comprise 10 billion by...
