Area of Science:

  • Ecology
  • Marine Biology
  • Biophysics

Background:

  • Hydrodynamic stress is a key factor shaping marine ecosystems.
  • Quantifying hydrodynamic forces in situ is challenging due to instrumentation costs and reliability issues.
  • Barnacles exhibit phenotypic plasticity in response to environmental conditions.

Purpose of the Study:

  • To investigate the potential of barnacles, specifically ivory barnacles (Amphibalanus eburneus), as biological indicators of hydrodynamic flow.
  • To determine if morphological changes in barnacle cirri can be used to quantify relative flow differences.

Main Methods:

  • Reciprocal transplant experiments of Amphibalanus eburneus between wave-exposed and wave-protected sites.
  • Transplantation of barnacles into controlled low (<5 cm/s) and high (>25 cm/s) flow environments, with some individuals shielded to reduce flow.
  • Measurement of cirral dimensions to assess morphological plasticity in response to varying flow regimes.

Main Results:

  • Amphibalanus eburneus exhibited significant differences in cirral morphology between high and low flow sites.
  • Phenotypic changes in barnacle morphology were observed within two weeks and were reversible upon relocation.
  • Flow velocity, rather than wave action alone, was identified as the primary driver of barnacle morphological changes.

Conclusions:

  • Barnacles serve as effective, low-cost biological indicators for assessing relative differences in hydrodynamic flow.
  • The phenotypic plasticity of barnacle cirri provides a valuable tool for ecological studies in wave-swept and estuarine environments.
  • This method offers an accessible alternative to traditional instrumentation for flow measurement.
