Ecological Disturbance02:26

Ecological Disturbance

20.7K
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

21.3K
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

26.1K
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.

Source: Yi, Y., et al. Plant-Microbe Interaction: Transcriptional Response of Bacillus Mycoides to Potato Root Exudates. J. Vis. Exp. (2018)This video demonstrates the preparation and treatment of Bacillus mycoides cultures to study plant-microbe interactions. It outlines the steps from streaking a stock culture and incubating it in liquid medium to exposing the bacteria to plant root exudates under agitation. The process culminates in harvesting and flash-freezing the bacterial cells for...

A Hydroponic Co-cultivation System for Simultaneous and Systematic Analysis of Plant/Microbe Molecular Interactions and Signaling

14.7K
The described hydroponic cocultivation system supports intact plants with metal mesh screens and cocultivates them with bacteria. Plant tissue, bacteria, and secreted molecules can then be separately harvested for downstream analyses, simultaneously allowing for the molecular responses of both plant hosts and interacting microbes or microbiomes to be...

Investigation of Plant Interactions Across Common Mycorrhizal Networks Using Rotated Cores

13.2K
Most plants within communities likely are interconnected by arbuscular mycorrhizal (AM) fungi, but mediation of plant interactions by them has been investigated primarily by growing plants with versus without mycorrhizas. We present a method to manipulate common mycorrhizal networks among mycorrhizal plants to investigate their consequences for plant...

Area of Science:

  • Ecology
  • Microbiology
  • Network Science

Background:

  • Above-belowground ecology in natural ecosystems, particularly plant-microbe associations at regional scales, remains poorly understood.
  • Macroscopic interkingdom relationships are well-studied, but fine-scale interdomain interactions are less clear.

Purpose of the Study:

  • To develop a workflow for constructing interdomain ecological networks (IDEN) between plants and microbes (bacteria and archaea).
  • To investigate the topological features and specialization patterns of plant-microbe associations across 30 latitudinal forests in China.

Main Methods:

  • Development of a novel workflow to construct interdomain ecological networks (IDEN).
  • Analysis of ecological network topology, including connectance, nestedness, specialization, and modularity.
  • Comparison of observed networks with randomly rewired networks to assess significance.

Main Results:

  • Regional IDEN exhibited high connectance, nested structure, asymmetric specialization, and modularity.
  • Plant species demonstrated strong preferences for specific microbial groups, indicating specialized associations.
  • Plant distribution showed higher endemicity than microbial distribution across the studied forests.

Conclusions:

  • The study successfully demonstrates interdomain species associations between plants and microbes in natural forest ecosystems.
  • IDEN analysis provides new insights into the structure and function of meta-communities across different domains.
  • Findings highlight the specialized nature of plant-microbe interactions and their ecological significance.
