Hypothesis
The developmental response to the oxygen environment would be family specific.
Conclusion
Zebrafish families vary in their plastic response to hypoxia, indicating genetic variation may aid adaptation to changing environments.
Supporting Evidence
- Cardiac output varied significantly between zebrafish families.
- Physiological traits related to cardiac output showed family-specific responses to hypoxia.
- No overall trend in response to oxygen levels was observed across families.
Takeaway
Different families of zebrafish react differently to low oxygen levels, which might help them survive in changing environments.
Methodology
Zebrafish were bred in controlled environments, with one group exposed to normal oxygen levels and the other to low oxygen levels, to assess cardiovascular responses.
Limitations
The study did not distinguish between genetic and maternal effects on developmental responses.
Participant Demographics
Zebrafish (Danio rerio) from various families.
