Changes in Average Annual Precipitation in Argentina’s Pampa Region and Their Possible Causes [PDF]

, 2015
Changes in annual rainfall in five sub-regions of the Argentine Pampa Region (Rolling, Central, Mesopotamian, Flooding and Southern) were examined for the period 1941 to 2010 using data from representative locations in each sub-region.

Implications of water management on methane emissions and grain yield in paddy rice: A case study under subtropical conditions in Brazil using the CSM-CERES-Rice model

Agricultural Water Management
Rice (Oryza sativa L.) is a staple food and plays a crucial role in the food security of many countries. However, rice cultivation is associated with significant methane (CH4) emissions, contributing to overall greenhouse gas emissions and, thus, climate

Disentangling conservation asymmetries through socio‐economic transboundary factors across the Alto Paraná Atlantic Forest of South America

People and Nature, Volume 8, Issue 5, Page 1328-1348, May 2026.
Abstract Ecoregions are often defined based on homogeneous biophysical and ecological conditions and are optimal spatial units for designing conservation strategies. However, transboundary ecoregions such as the Alto Paraná Atlantic Forest (APAF) experience asymmetrical conservation outcomes, understood here as cross‐border differences, resulting from ...

Ecological and Historical Correlates of Taxonomic, Phylogenetic, and Functional Diversity of Amphibians in South American Rainforests and Savannas

Ecology and Evolution, Volume 16, Issue 4, April 2026.
This study identifies the key drivers of anuran amphibian diversity (taxonomic, functional, and phylogenetic) across South America's Cerrado, Amazonia, and Atlantic Rainforest. Although taxonomic and phylogenetic diversity consistently increased with long‐term climatic stability in all regions, functional diversity was primarily influenced by current ...

Biogeographic History and Morphological Trait Influence in the Diversification of the Subtribe Calothecinae (Poaceae)

Journal of Biogeography, Volume 53, Issue 4, April 2026.
ABSTRACT Aim The biodiversity of the Neotropics has been shaped by complex interactions over time with several major geological and climatic events linked to the diversification of lineages. The subtribe Calothecinae (Poaceae) comprises 28 species adapted to open environments, ranging from lowlands to high‐altitude grasslands in America.

Should I Stay or Should I Go? Using Open Data to Investigate Movements of the Streamer‐Tailed Tyrant (Gubernetes yetapa)

Austral Ecology, Volume 51, Issue 3, March 2026.
ABSTRACT Migration is a global phenomenon shaping bird assemblages in response to seasonal climate variations. The Streamer‐tailed Tyrant (Gubernetes yetapa) is a Neotropical bird associated with wetlands. Although considered common across most of its range, its natural history remains poorly understood, and some authors have suggested it may exhibit ...

EAACI Guidelines on the Importance of Green Space in Urban Environments for Allergy and Asthma Prevention

Allergy, Volume 81, Issue 3, Page 635-650, March 2026.
ABSTRACT The allergy and asthma epidemic in urban societies following World War II is mostly caused by changes in the environment, diet and lifestyle. Disconnection of urban populations from the wider environment has reduced the protective factors building up immunological resilience.

Comportement de la structure des sols de la pampa inondable et de la pampa agricole de l'Argentine

, 2006
Soils of the Argentine Pampas have been developed over same parent material (loess), but evolved under different topography and land use. This led to different soil structural behaviour.
