Comparative thermal ecophysiology in Pristidactylus scapulatus populations from the Puna region of Argentina

Zoology, 2021
Reptiles are important models for understanding fundamental aspects of physiological ecology and for assessing how environmental change can impact biodiversity. Abiotic factors (micro-environmental temperatures, operative temperatures, thermal quality) may vary geographically along an altitudinal and latitudinal gradient, and therefore the different ...

Along the Silenced Footsteps of Latin American Pastoralists: From Mexico to Argentina, a Journey Through Pastoral Systems in Latin America

The Journal of Latin American and Caribbean Anthropology, Volume 31, Issue 1, March 2026.
ABSTRACT Pastoralism worldwide faces a complex landscape of increased pressures and exclusion. Beyond ecological and economic challenges, pastoralists suffer eroding cultural identity, limited generational renewal, and political marginalization. Yet pastoral livelihoods are increasingly recognized as stewards of sustainable futures and amongst the best

Breeding seasonality in Charadriiformes on the Andean Altiplano is influenced by rain and possibly flood risk

Ecosphere, Volume 17, Issue 2, February 2026.
Abstract The Andean Altiplano in South America represents a remarkable mountain ecosystem with unique wildlife. However, knowledge of breeding ecology for birds inhabiting Andean Altiplano is scarce, relying mostly on anecdotal records, and drivers of breeding phenology remain unexplored.

Projections of Atmospheric Moisture Transport Over South America in a Changing Climate

International Journal of Climatology, Volume 46, Issue 2, February 2026.
End‐of‐century (2071–2100) climate projections show significant contrasts in atmospheric moisture over South America, with increased divergence over Northern Chile and Eastern Brazil and stronger convergence over the La Plata and Magdalena basins. Moisture convergence raises risks of extreme rainfall and floods, while divergence intensifies droughts ...

Hidroecosistemas de la Puna y Altos Andes de Argentina

, 2016
Los humedales son zonas en donde el agua es el principal factor que controla el ambiente así como biodiversidad asociada. Especialmente en zonas áridas como la Puna, estos sistemas son de enorme importancia para la biodiversidad y las poblaciones locales que dependen de los servicios ecosistémicos que éstos proveen. En éste trabajo presentamos un mapeo
