Species inequality in scientific study.

Area of Science:

• Conservation Biology
• Zoology
• Bibliometrics

Background:

• Debate exists on whether conservation efforts should prioritize critically endangered species or common species across large areas.
• This debate extends to the distribution of scientific research effort among different species.

Purpose of the Study:

• To assess the scientific equity in research attention given to 1909 species of mammals, birds, reptiles, and amphibians in southern Africa.
• To determine if species' conservation status, particularly their listing on the International Union for Conservation of Nature (IUCN) Red List, influences scientific research investment.

Main Methods:

• A quantitative analysis was performed, correlating the number of scientific papers published on each species with its IUCN Red List status.
• Data encompassed 1909 species of mammals, birds, reptiles, and amphibians from southern Africa.

Main Results:

• Threatened large mammals and reptiles garnered more scientific papers than their non-threatened counterparts.
• Conversely, threatened small mammals and amphibians received less scientific attention compared to non-threatened species.
• Threatened birds showed an intermediate level of scientific attention.
• Significant disparities in scientific investment were observed across taxonomic groups, with large mammals receiving disproportionately more attention than other groups.

Conclusions:

• Species' threat status influences scientific research effort, but this relationship varies across animal groups.
• Factors beyond conservation status, such as pest management and commercial interests, also drive scientific investment in certain species.
• The distribution of scientific attention is highly unequal, with a few species dominating research while many others lack sufficient data for conservation.
