Stable Isotope Analysis

Tracing food-web relationships and ecological change in freshwater ecosystems

UNDERSTANDING AQUATIC FOOD WEBS

Following energy through freshwater ecosystems

Stable isotope analysis is a powerful tool for investigating feeding relationships and the movement of energy through aquatic food webs. By comparing isotope signatures among fish, invertebrates, and potential food sources, we can explore how organisms use resources and how their trophic relationships vary across habitats and environmental conditions. These insights help connect ecological processes with questions about freshwater conservation and management.

STEP 01

Collect

Sample fish, aquatic invertebrates, and other food-web components in the field.

STEP 02

Analyse

Use laboratory measurements of stable isotopes to characterize biological samples.

STEP 03

Interpret

Compare isotope patterns to investigate food sources, trophic relationships, and ecosystem change.
