- 为了测试进化论关于成功物种的非重叠空间分布的预测.
- 确定类动物用来维持物种多样性的生物地理战略.
主要方法:
- 红外摄像头陷被用来收集2017-2021年在中国四个国家自然保护区 (NNR) 的物种分布数据.
- 鉴定了七种类动物物种: *Arctonyx collaris*, *Meles leucurus*, *Martes foina*, *Martes flavigula*, *Mustela altaica*, *Mustela nivalis* 和 *Mustela sibirica*. 这些物种包括: *Arctonyx collaris*, *Meles leucurus*, *Martes foina*, *Martes flavigula*, *Mustela altaica*, *Mustela nivalis* 和 *Mustela sibirica*.
- 根据Ricklefs对生物社区的定义,分析了物种关联网络.
主要成果:
- 确定了五种不同的物种协会网络,其中类动物分布在它们之间.
- 同一个属的类动物,如Martes foina和Martes flavigula,以避免竞争而占据不同的网络.
- 具有不同生态的物种要么在相同的网络中与空间回避共存,要么占用单独的网络;在不同属和子家族之间观察到不对称的关联.

00:54Distribution 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...

01:32What is Natural Selection?
115.0K
Natural selection is an evolutionary process in which individuals with survival-promoting traits reproduce at higher rates. These favorable traits become more common within a population or species. Naturally selected traits initially arise via random genetic mutations. In order for selection to occur, there must be variation within a population, the trait controlling the variation must be heritable, and there must be an evolutionary advantage for variation in the trait.

02:31Habitat Fragmentation
17.4K
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.
