Nest habitat selection by the Austral parakeet in north‐western Patagonia
Austral Ecology, 2012 AbstractIdentifying habitat or nesting microhabitat variables associated with high levels of nest success is important to understand nest site preferences and bird–habitat relationships. Little is known about cavity availability and nest site requirements of cavity nesters in southern hemisphere temperate forests, although nest site limitation is ...

Integrative Conservation, Volume 5, Issue 1, Page 86-103, March 2026.Urbanization may alter bird foraging. Austral Parakeets (Enicognathus ferrugineus) in Patagonia rely on introduced plants in urban areas, especially in winter, despite preferring natives in the wild. This seasonal reliance on introduced species highlights urbanization trade‐offs and underscores the need to manage green areas with native plants to ...

Earth Surface Processes and Landforms, Volume 51, Issue 2, February 2026.We provide a geomorphological analysis of Cordillera Vilcanota and use morphostratigraphic principles to reconstruct palaeo icefield extent and palaeoglacier readvances, likely during the Antarctic Cold Reversal and Younger Dryas. We find evidence of temperate and polythermal ice margins, with limited glaciofluvial landform generation.

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 ...
