Stable isotopes (δ¹³C, δ¹⁸O, δ¹⁵N) have revolutionized paleoecology studies. But how have these tools been applied in South America, one of the world’s richest fossil archives? ⚛️🌎 This is the first bibliometric and conceptual review to answer that question.

🖥️We analyzed 80 studies (1994–2024) to explore: •Temporal and taxonomic biases •Research trends, gaps and emerging topics •Collaboration networks and gender equity

📈 The field has grown exponentially, especially in the last 5 years. But studies are heavily skewed toward: ✔ the Quaternary (77% of the papers) ✔ certain taxa (e.g., Equidae, Camelidae, Toxodontidae)

🌎 Geographically, most works are concentrated in Argentina and Brazil. Countries like Paraguay and Venezuela are underrepresented. We need more balanced regional sampling to understand continent-wide patterns.

The most frequent keywords (“Isotope”, “Pleistocene”, “Diet”, “Paleoecology”, and “Carbon”) highlight a primary focus on evaluating the paleodiets and ecological roles of extinct taxa, and recent years show growing interest in Ecological niche modeling.

Network analysis using clustering methods provided valuable insights into collaborative structure trends. Co-authorship analysis revealed a highly collaborative landscape, with 90% of identified clusters involving international partnerships.

🌎 South American researchers are increasingly assuming leadership roles in the production of isotopic research over the last decade.

Gender analysis revealed significant imbalances in female participation. Promoting equitable representation in scientific authorship is crucial not only for social justice but also to enrich research by incorporating diverse perspectives.

🦏🦣🦌 LARGE paper alert!!! We tracked 60 million years of large herbivore evolution—over 3,000 fossil species—to uncover how ecosystems have changed and reorganized through time. What we found might help us understand the next big tipping point 🧵👇 https://t.co/l6pLrehdlp

Ancient sloths ranged in size from tiny climbers to ground-dwelling giants. Now, researchers report in Science that this body size diversity was largely shaped by sloths’ habitats, and that these animals’ precipitous decline was likely a result of increasing human pressures.
