En cuestión de semanas, los primeros brotes verdes emergen entre las cenizas, transformando el paisaje devastado en un mosaico inesperado de vida.

¿Puede la vegetación recuperarse por sí sola después de un gran incendio?

Mientras que algunos incendios abren oportunidades para que la vida renazca con fuerza, los de alta intensidad pueden iniciar una degradación irreversible si no actuamos con inteligencia.

New paper out!

This review looks at 30 years of stable isotope studies on South American fossil mammals, exploring research trends, paleoecological insights, and future directions.

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.

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.

This systematic literature analysis offers a comprehensive understanding of the field’s progress over the past three decades.

🧭We hope this review becomes a roadmap for future work.

🌍 What structures life on Earth?
In the 1980s, Brown and Maurer laid the foundations of macroecology with a simple, powerful idea:
space, time… and FOOD.

Where food is, how it's distributed, and who gets access to it.

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. scim.ag/43dd0t7

The emergence and demise of giant sloths

The emergence of multi-tonne herbivores is a recurrent aspect of the Cenozoic mammalian radiation. Several of these giants have vanished within the past 130,000 years, but the timing and macroevolutio...
