Distribution and Dispersion

21.7K
To understand intra-specific interactions in populations, scientists measure the spatial arrangement of species individuals. This geographic arrangement is known as the species distribution or dispersion. Highly territorial species exhibit a uniform distribution pattern, in which individuals are spaced at relatively equal distances from one another. Species that are highly tied to particular resources, such as food or shelter, tend to concentrate around those resources, and thus exhibit a...

  • 了解害虫机构风险和公众检测率可以为有效的监测策略提供信息.
  • 正式的早期检测调查计划从害虫入侵动态的知识中受益.

研究的目的:

  • 确定与美国新的害虫机构相关的县级属性.
  • 确定影响公众检测到新害虫与其他来源之间的因素.
  • 为优化害虫监测规划提供空间显式数据.

主要方法:

  • 分析了美国 (2010-2018年) 113次新增害虫入侵的数据.
  • 量化县级的地理,人口和经济因素.
  • 统计建模以评估害虫的建立和检测概率,控制样本选择偏差.

主要成果:

  • 随着人口密度,靠近港口 (<250公里) 和有利的气候条件,害虫的建立可能性增加.
  • 在农作物销售价值较高,人口较少的县,公众检测的可能性较小.
  • 高农业价值与公共检测的减少相关,可能是由于专业监督的增加.

结论:

  • 空间显式模型预测了美国各县的新害虫建立和公共检测概率.
  • 调查结果通过为决策提供定量投入,支持有针对性的监测规划.
  • 了解检测来源是提高早期害虫检测计划效率的关键.
