概括
使用摄像头陷估计查克马 (Papio ursinus) 密度是可行的保护. 摄像头捕捉方法提供了可信的人口估计,以管理人与之间的冲突和农作物损害.
科学领域:
- 野生动物生态学野生动物生态学
- 灵长类动物种群动态
- 保护技术 保护技术
背景情况:
- 人与野生动物之间的冲突,包括像这样的灵长类动物 (Papio spp. ),随着人类人口的增长而增加.
- 有效的保护和冲突缓解策略需要准确的人口估计,但对于查克马 (Papio ursinus) 的人口估计很少,特别是在农业地区.
- 传统的密度估计方法对于商业农田上的通常是不切实际的.
研究的目的:
- 评估摄像头捕捉方法的潜力,以估计查克马的密度.
- 为了比较使用摄像头陷 (CTDS) 和随机遭遇模型 (REM) 监测种群的远距离采样性能.
- 为保护政策和策略提供信息,以减轻人与的相互作用和作物损失.
主要方法:
- 现场测试摄像头捕捉技术,特别是CTDS和REM,以估计查克马的密度.
- 通过两种摄像头捕捉方法得出的密度估计的比较.
- 分析影响存在和分布的因素,如睡眠地点,作物可用性和水源.
主要成果:
- 查克马的密度估计在1-3个/平方公里之间,与现有的丰度数据保持一致.
- 无论是CTDS还是REM都提供了可信的密度估计,表明它们对监测种群的潜力.
- 的分布主要受睡眠地点的可用性影响,这与作物位置一起与水的可用性有关.
- 在检测中,相机间的异质性被确定为这两种方法的不精确性的重要来源.
结论:
- 使用CTDS和REM的摄像头陷,为估计农田上的查克马密度提供了一个可行的替代方案.

How animals obtain and eat their food is called foraging behavior. Foraging can include searching for plants and hunting for prey and depends on the species and environment.

02:16Light Acquisition
9.3K
In order to produce glucose, plants need to capture sufficient light energy. Many modern plants have evolved leaves specialized for light acquisition. Leaves can be only millimeters in width or tens of meters wide, depending on the environment. Due to competition for sunlight, evolution has driven the evolution of increasingly larger leaves and taller plants, to avoid shading by their neighbors with contaminant elaboration of root architecture and mechanisms to transport water and nutrients.

02:30Naturalistic Observations

If you want to understand how behavior occurs, one of the best ways to gain information is to simply observe the behavior in its natural context. However, people might change their behavior in unexpected ways if they know they are being observed. How do researchers obtain accurate information when people tend to hide their natural behavior? As an example, imagine that your professor asks everyone in your class to raise their hand if they always wash their hands after using the restroom. Chances...
