Biodiversity research shows significant spatial bias, with wealthy nations dominating studies while biodiverse regions, especially in the Global South, are underrepresented. Addressing these imbalances is crucial for effective conservation efforts.
Area of Science:
- Ecology
- Conservation Biology
- Bibliometrics
Background:
- Biodiversity loss is a critical global challenge.
- Efforts to quantify biodiversity changes and impacts are ongoing.
- Understanding research patterns is key to addressing conservation needs.
Purpose of the Study:
- To identify and analyze spatial biases in global biodiversity research.
- To assess the geographical distribution of research output and key researchers.
- To highlight research deficits in biodiversity hotspots and threatened regions.
Main Methods:
- Comprehensive bibliometric analysis of 134,321 publications.
- Assessment of research focus (terrestrial, aquatic, species level).
- Analysis of researcher collaboration networks and institutional affiliations.
Main Results:
- Research is concentrated in wealthy countries, with deficits in biodiverse regions.
- Core researchers are primarily based in North America and Europe.
- Biodiversity research disproportionately focuses on terrestrial systems, plants, and species level.
Conclusions:
- Significant spatial imbalances exist in biodiversity research.
- Capacity building in the Global South is essential.
- Improved, shared, and curated biodiversity databases are needed.
