Hypothesis
Does taxonomic bias exist in parental care research, and have patterns of bias changed over the past decade?
Conclusion
Parental care research exhibits significant bias towards birds, which likely represents a disproportionate amount of the research despite the existence of many other taxa.
Supporting Evidence
- Birds comprised 58% of the articles on parental care, indicating a significant taxonomic bias.
- Taxonomic citation bias was significantly influenced by taxon, with parental care articles exhibiting lower levels of bias compared to general animal behavior articles.
- Despite warnings about taxonomic bias, the levels of bias in parental care research have not declined over the past decade.
Takeaway
This study found that most research on parental care focuses on birds, even though there are many other animals that also take care of their young.
Methodology
Analyzed parental care articles published in six leading journals from 2001–2010 using statistical tests including ANCOVA and ANOVA.
Potential Biases
Potential bias in publication practices may skew the representation of different taxa in parental care research.
Limitations
The study may not capture all parental care research across all taxa, and the focus on specific journals may introduce bias.
