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

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.

The Tree of Life - Bacteria, Archaea, Eukaryotes

39.1K
The “tree of life” describes the evolution of life and the evolutionary relationships between organisms. The root of the tree is the common ancestor to all life on Earth. All other species radiate from this point, much like the branches of a tree. The numerous tips of these branches on the tree of life represent every living, or extant, species. Extinct species, which are species that no longer exist, can be found towards the center of the tree. Currently, these organisms, both...

Survival Tree01:19

Survival Tree

436
Survival trees are a non-parametric method used in survival analysis to model the relationship between a set of covariates and the time until an event of interest occurs, often referred to as the "time-to-event" or "survival time." This method is particularly useful when dealing with censored data, where the event has not occurred for some individuals by the end of the study period, or when the exact time of the event is unknown.

Phylogenetic Trees

49.9K
Phylogenetic trees come in many forms. It matters in which sequence the organisms are arranged from the bottom to the top of the tree, but the branches can rotate at their nodes without altering the information. The lines connecting individual nodes can be straight, angled, or even curved.

Area of Science:

  • Ecology
  • Environmental Science
  • River Basin Management

Background:

  • Aquatic ecological regionalization and function regionalization are crucial for effective water resource management and ecosystem utilization in river basins.
  • These fields have been subjects of extensive research in China for over a decade, yet common challenges persist.

Purpose of the Study:

  • To systematically analyze the relationship between aquatic ecological regionalization and aquatic ecological function regionalization.
  • To address existing problems in the field and provide a clear process framework for aquatic ecological function regionalization within river basins.

Main Methods:

  • A systematic analysis of aquatic ecological zoning and aquatic ecological function types was conducted.
  • The study utilized a dual tree structure to develop the RFCH process and the diamond conceptual model.
  • Aquatic ecological function regions were classified based on a three-class aquatic ecological regionalization system, using the Liaohe River basin as a case study.

Main Results:

  • The study elucidated the relationship between aquatic ecological regionalization and aquatic ecological function regionalization.
  • A novel process framework, the RFCH process, and a conceptual model were proposed.
  • A practical classification of aquatic ecological function regions was achieved for the Liaohe River basin.

Conclusions:

  • The developed process framework offers a systematic approach to aquatic ecological function regionalization for river basins.
  • This research contributes to improved water environmental management and rational aquatic ecosystem utilization.
  • The findings provide a valuable methodology for future regionalization studies in similar river systems.
