Ecological Disturbance02:26

Ecological Disturbance

21.1K
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.

Ecological Succession02:17

Ecological Succession

21.6K
Ecological succession is influenced by the processes of facilitation, inhibition, and toleration. Facilitation occurs when early successional species create more favorable ecological conditions for subsequent species, such as enhanced nutrient, water, or light availability. In contrast, inhibition happens when early successional species create unfavorable ecological conditions for potential successive species, such as limiting resource availability. In some cases, later successional species...

Ecological Niches

26.7K
All organisms have a position within an ecosystem. The complete set of living and nonliving factors—including food resources, climate, and terrain—that define the position of a given organism are collectively referred to as the organism’s ecological niche.

Protein Networks02:26

Protein Networks

4.6K
An organism can have thousands of different proteins, and these proteins must cooperate to ensure the health of an organism. Proteins bind to other proteins and form complexes to carry out their functions. Many proteins interact with multiple other proteins creating a complex network of protein interactions.
These interactions can be represented through maps depicting protein-protein interaction networks, represented as nodes and edges. Nodes are circles that are representative of a protein,...

Network Covalent Solids02:18

Network Covalent Solids

16.2K
Network covalent solids contain a three-dimensional network of covalently bonded atoms as found in the crystal structures of nonmetals like diamond, graphite, silicon, and some covalent compounds, such as silicon dioxide (sand) and silicon carbide (carborundum, the abrasive on sandpaper). Many minerals have networks of covalent bonds.
To break or to melt a covalent network solid, covalent bonds must be broken. Because covalent bonds are relatively strong, covalent network solids are typically...

Area of Science:

  • Ecological network analysis
  • Landscape ecology
  • Urban planning

Background:

  • Habitat fragmentation impacts species survival.
  • Ecological networks assess landscape-species relationships.
  • Urban expansion threatens natural habitats.

Purpose of the Study:

  • Simulate woodland and wetland ecological networks in Qingdao.
  • Assess the impact of construction land expansion on ecological networks.
  • Develop an ecological security pattern for Qingdao.

Main Methods:

  • Least cost path method for network simulation.
  • Graph theory for network element importance assessment (betweenness centrality, correlation length-percentage of importance of omitted patches).
  • Analysis of construction land changes from 2005-2013.

Main Results:

  • Ecological network framework quantifies land attributes and connections.
  • Significant wetland loss due to construction land expansion (2005-2013).
  • Previous assessments overlooked the role of specific woodland and wetland connections.

Conclusions:

  • Ecological network analysis provides a framework for quantifying ecological attributes and connections.
  • Delineating ecological security patterns optimizes regional ecological bases.
  • This approach offers spatial guidance for urban expansion and ecological conservation.
