RETRACTION: Ocean Acidification Disrupts the Innate Ability of Fish to Detect Predator Olfactory Cues
Ecology Letters
|August 5, 2026
Summary
This retracted study investigated how ocean acidification affects fish's ability to detect predator cues. Data errors led to the retraction, undermining the original findings on sensory disruption.
Area of Science:
- Marine Biology
- Ecology
- Environmental Science
Background:
- Ocean acidification poses a significant threat to marine ecosystems.
- Understanding the impact of altered water chemistry on marine life is crucial.
- Fish rely on olfactory cues for predator detection and survival.
Purpose of the Study:
- To investigate the effects of ocean acidification on fish's innate ability to detect predator olfactory cues.
- To assess potential disruptions in sensory perception due to changing ocean conditions.
Main Methods:
- The study involved exposing fish to varying levels of acidity.
- Olfactory responses to predator cues were measured.
- Statistical analysis was intended to evaluate the impact of acidification.
Main Results:
- The original article reported that ocean acidification impairs fish's ability to detect predator scents.
- Specific data anomalies, including repeated blocks and missing information, were identified.
- The provided data did not consistently align with the described observation methods.
Conclusions:
- The article has been retracted due to statistically implausible data variances and substantial errors.
- The publisher and editor lack confidence in the published results.
- The retraction highlights the importance of rigorous data handling and quality control in scientific research.

Osmoregulation in Fishes
When cells are placed in a hypotonic (low-salt) fluid, they can swell and burst. Meanwhile, cells in a hypertonic solution—with a higher salt concentration—can shrivel and die. How do fish cells avoid these gruesome fates in hypotonic freshwater or hypertonic seawater environments?
Marine Microbial Ecology
Marine microbial ecosystems are shaped by distinct physicochemical limits, including high salinity, low nutrient availability, and fluctuating oxygen levels. These conditions favor smaller microbial cell sizes, which maximize their surface-to-volume ratio for efficient nutrient uptake.Microbial activity and community composition are closely linked to biogeochemical cycles, particularly in dynamic environments like estuaries, where halotolerant microbes thrive in response to variable salinity...
Instinctive Drift
Instinctive drift refers to the tendency of animals to revert to their innate behaviors despite repeated reinforcement. Breland and Breland demonstrated this concept in an experiment with a raccoon. The raccoon was trained to pick up two coins and place them in a container in exchange for food. Initially, the raccoon learned to associate the coins with food, making them a conditioned stimulus or a substitute for food. However, over time, the raccoon became less willing to put the coins into the...
