概括
城市化对植物多样性产生影响. 垂直城市化,就像建筑体积一样,增加了本地植物的丰富性,而水平因素则影响城市绿地中的非本地物种.
科学领域:
- 城市生态城市生态学
- 植物生物多样性 植物生物多样性
- 城市规划 城市规划
背景情况:
- 城市化显著改变生态系统,导致息地丧失和生物多样性下降.
- 城市自发植物对于生态系统服务和环境监测至关重要.
- 与水平因素相比,垂直城市化对植物多样性的影响仍未得到充分研究.
研究的目的:
- 在多维城市化下调查自然植物多样性的空间模式和驱动因素.
- 分析垂直和水平城市化指标对总,本土和非本土植物物种丰富性的影响.
- 为可持续城市规划和生物多样性保护提供见解.
主要方法:
- 在中国长春市245个城市绿地块的1147个草本地块中对自发植物进行了全面的调查.
- 收集了408种自发植物物种的数据,根据生命形式,起源 (本土/非本土) 和分散方法分类它们.
- 通过回归分析分析了多维城市化指标 (垂直和水平) 和植物多样性指标上的补丁特征的影响.
主要成果:
- 原生植物的多样性在方形绿地和灌木间隙中最高;非原生植物的多样性在棕色地块中突出.
- 垂直城市化 (建筑体积) 对总体,本土和自主自发植物的丰富性产生了积极的影响.
- 横向的城市化 (不透气的表面,距离市中心) 显著影响了非本土和无菌植物的丰富性.
结论:
- 自发的植物多样性表现出独特的空间模式,受到垂直和水平城市化的影响.
- 垂直城市化在塑造本土植物多样性方面发挥着关键作用,而水平因素对非本土物种更为关键.

Every organism has an optimum temperature range within which healthy growth and physiological functioning can occur. At the ends of this range, there will be a minimum and maximum temperature that interrupt biological processes.

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...

Cell Diversity

The concept of a cell started with microscopic observations of dead cork tissue by Robert Hooke in 1665. Hooke coined the term "cell" based on the resemblance of the small subdivisions in the cork to the rooms that monks inhabited, called cells. About ten years later, Antonie van Leeuwenhoek became the first person to observe the living and moving cells under a microscope. In the century that followed, the theory that cells represented the basic unit of life developed.

Environmental Applications of Microorganisms

Microorganisms play a pivotal role in maintaining ecosystem balance by recycling essential elements such as carbon, nitrogen, and phosphorus, as well as supporting processes like bioremediation, wastewater treatment, and biofuel production.Microbes in Elemental CyclesIn the carbon cycle, microorganisms decompose organic matter, releasing carbon dioxide via aerobic respiration. This carbon dioxide is subsequently used by photosynthetic organisms to synthesize organic compounds, closing the...

Adaptations that Reduce Water Loss
27.9K
Though evaporation from plant leaves drives transpiration, it also results in loss of water. Because water is critical for photosynthetic reactions and other cellular processes, evolutionary pressures on plants in different environments have driven the acquisition of adaptations that reduce water loss.
