概括

在中国的贝塔多样性.

科学领域:

生态生态学生态生态学
生物多样性研究生物多样性研究
森林生态森林生态

背景情况:

贝塔多样性揭示了物种组成的空间变化,这对于理解社区聚集和生物多样性维护至关重要.
中国的 (Larix) 森林对环境条件和物种多样性至关重要,但缺乏详细的β-多样性研究.
很少有研究在这些森林中检查了β-多样性成分 (物种周转和化).

研究的目的:

确定中国树林中不同生命形式 (树,灌木,草) 的总β多样性及其组成部分.
评估影响这些生态系统中的β-多样性模式的主要驱动因素.
调查区分和分散限制在树林社区集会中的作用.

主要方法:

分析了中国各地的483个树林地块.
总贝塔多样性及其组成部分的量化 (物种周转,化结果).
评估地理,气候和海拔因素作为贝塔多样性的驱动因素.

主要成果:

树林的总贝塔多样性主要是由物种交换驱动的.
贝塔多样性和物种周转率随着地理,海拔和气候距离的增加而增加.
结巢导致的成分随着距离的增加而减少,地理和环境因素解释了多样性的很大一部分.
树林类型显著影响了总的贝塔多样性和物种周转.

结论:

生命形式影响中国树林中的β-多样性模式.
贝塔多样性是由利基区分和分散限制形成的.
这些发现提高了对树林生态系统中社区聚集机制的理解.

关键词:

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...
