A concept map visually connects key concepts in a subject using nodes and links. When creating an ecological concept map, considering keystone species can provide crucial insights into overall ecosystem structure and function. This article explores ideas for thoughtfully incorporating keystone species into a concept map.

What are Keystone Species?

Keystone species exert strong, disproportionate influence on their environment relative to their biomass or population size. Their impacts are critical for maintaining the organization and diversity of ecological communities.

Common examples include top predators, herbivores, and pollinators. Their niche roles drive important ecosystem processes. Few in number but large in ecological influence.

Benefits of Adding Keystone Species

Including keystone species in a concept map has several key benefits:

Benefits of Adding Keystone Species

  • Highlights central ecosystem roles. Calling out keystone species makes clear that not all organisms play equal structural roles.
  • Demonstrates complex connections. Visually tracing a keystone species’ relationships illustrates vulnerabilities if they are removed.
  • Maps ecosystem services. Linking services like water filtration or pollination to keystone interactions shows their origination.
  • Provides ecosystem resilience insights. The presence or absence of redundancy and fragility become apparent.
  • Entry points for niche exploration. Describing a keystone species’ niche builds understanding of associated predator/prey niches.

How to Add Keystone Species

Follow these steps to effectively add keystone species:

1. Identify relevant keystone organisms in the ecosystem you are mapping. Research specific keystone examples.

2. Add keystone nodes to appropriate locations in the concept map structure. Attach links to other nodes.

3. Indicate keystone status through labels, node shapes, or colors that distinguish them.

4. Map critical impacts by linking to species strongly influenced. Also show dependent ecosystem processes.

5. Connect ecosystem services that arise from keystone interactions.

6. Explain niche relationships by detailing keystone resources and mortality sources.

7. Analyze fragility – note sections that would collapse if the keystone node was removed.

8. Create comparison maps showing hypothetical ecosystem changes if a keystone node disappears.


Thoughtfully incorporating keystone species into ecological concept maps highlights their critical ecosystem roles and relationships. This provides valuable context for understanding ecosystem structure, function, resilience and services. When constructing concept maps, be sure to identify and integrate important keystone species nodes.
