概括

土地使用变化增加了灌木伤寒风险 (一种载体传播的疾病),森林碎片化是关键的驱动因素. 未来的高风险地区可能会出现在城市与自然息地的接口.

科学领域:

环境科学环境科学
流行病学流行病学
生态生态学生态生态学

背景情况:

全球土地使用变化引发了人们对传染病溢出影响的担忧.
草伤寒是一种媒介传播的疾病,其发病率和地理扩展率不断增加.
土地利用变化对灌木伤寒动态的具体影响尚不清楚.

研究的目的:

量化景观碎片化对中国灌木伤寒发病率的影响.
在不同的共享社会经济路径 (SSP) 下预测未来的灌木伤寒风险.
确定影响灌木伤寒的关键土地使用类型和碎片化水平.

主要方法:

构建一个全面的景观碎片化指数 (LFI).
应用一个通用的添加剂模型 (GAM) 来评估LFI对灌木伤寒的影响.
根据SSP1-2.6,SSP2-4.5,SSP3-7.0和SSP5-8.5情景预测未来的影响.

主要成果:

在LFI和灌木伤寒发病率之间发现了一个非线性正相关性 (RR=1.20每0.1 LFI增加).
森林碎片化产生了最显著的积极影响,其次是耕地碎片化;建筑用地碎片化显示出负面关联.
未来的高灌木伤寒风险区域主要预计在城市与自然息地接口,在SSP之间有所不同.

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...

What is Climate?

What is Climate?

Climate refers to the prevailing weather conditions in a specific area over an extended period. As the saying goes, “Climate is what you expect. Weather is what you get.” Climate is influenced by geographic factors, such as latitude, terrain, and proximity to bodies of water.

Steps in Outbreak Investigation

Steps in Outbreak Investigation

In the ever-evolving field of public health, statistical analysis serves as a cornerstone for understanding and managing disease outbreaks. By leveraging various statistical tools, health professionals can predict potential outbreaks, analyze ongoing situations, and devise effective responses to mitigate impact. For that to happen, there are a few possible stages of the analysis:
