Animal contests and microplastics: evidence of disrupted behaviour in hermit crabsPagurus bernhardus

AI summary Read the abstract

Researchers found that microplastic exposure disrupted shell-fighting contests in hermit crabs, impairing defenders' ability to assess opponents and reducing attackers' rapping strength, suggesting broader behavioral impacts on marine animals than previously recognized.

Raw Data from All Shell Selection Experiments from Microplastics disrupt hermit crab shell selection

AI summary Read the abstract

This dataset contains raw behavioral data from shell selection experiments in hermit crabs exposed to microplastics, recording whether crabs contacted and entered optimal shells and the latency for these behaviors. The data support a published study showing that microplastics disrupt normal shell selection behavior in hermit crabs.

Supplementary material from "Microplastics disrupt hermit crab shell selection"

AI summary Read the abstract

Lab experiments showed that hermit crabs exposed to polyethylene microplastic spheres for five days were less likely to investigate, contact, or enter an optimally-sized shell than unexposed crabs. Since shell selection is critical for hermit crab survival, microplastic-induced impairment of this behavior could have meaningful effects on their fitness in polluted environments.

Does microplastic exposure and sex influence shell selection and motivation in the common European hermit crab, Pagurus bernhardus?

AI summary Read the abstract

This study tested whether microplastic exposure influences shell selection behavior and motivational drive in hermit crabs, finding that MP-exposed crabs showed altered preferences for new shells. The results suggest that microplastic contamination may impair sensory or cognitive processes important for survival in hermit crabs.
