概括

一个新的数据库,DEFID2,现在绘制了超过65万个欧洲森林昆虫和疾病干扰的地图. 该资源追踪影响森林生态系统服务的生物干扰,帮助生态研究和气候建模.

科学领域:

生态生态学生态生态学
林业林业林业林业林业
遥感遥感遥感遥感
气候科学气候科学

背景情况:

由于气候变化,昆虫和疾病的爆发正在加剧欧洲森林的生物干扰.
这些干扰威胁着重要的森林生态系统服务,如碳捕获和生物多样性保护.
缺乏空间详细的泛欧洲数据库,阻碍了对这些事件的研究和管理.

研究的目的:

引入欧洲森林昆虫和疾病扰乱数据库 (DEFID2),这是一个全欧洲的新型资源.
提供关于1963年至2021年森林昆虫和疾病干扰的协调,地理引用的数据.
支持生态研究,监测和土地气候建模中的大规模应用.

主要方法:

汇编了来自欧洲八个国家的超过65万个地理引用记录 (多边形/点).
整合了定性属性 (代理物,宿主物种,触发因素,干预) 和定量卫星数据 (Landsat NBR,LandTrendr).
干扰指标的表征,包括干扰的开始,持续时间,大小,速度和与其他干扰的相互作用 (风吹,野火).

主要成果:

DEFID2数据库提供了关于欧洲森林生物干扰的全面,协调的数据集.
它包括有关干扰特征和潜在驱动因素的详细定性和定量信息.
数据库涵盖了1963-2021年,提供了对干扰动态的长期视角.

结论:

DEFID2是了解和监测欧洲森林生物干扰的独特资源.
它有助于改善生态过程的理解,实验设计和气候模型的整合.
鼓励继续共享数据,以提高数据库的范围和用于森林管理和研究的实用性.

Ecological Disturbance

Ecological Disturbance

An ecological disturbance is a temporary disruption in the environment resulting from abiotic, biotic, or anthropogenic factors, causing a pronounced change in an ecosystem. The impact of an ecological disturbance, which can depend on its intensity, frequency, and spatial distribution, plays a significant role in shaping the species diversity within the ecosystem.

Habitat Fragmentation

Habitat Fragmentation

Habitat fragmentation describes the division of a more extensive, continuous habitat into smaller, discontinuous areas. Human activities such as land conversion, as well as slower geological processes leading to changes in the physical environment, are the two leading causes of habitat fragmentation. The fragmentation process typically follows the same steps: perforation, dissection, fragmentation, shrinkage, and attrition.
