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

Grass-Fed Beef Production Systems of Argentina's Flooding Pampas

Outlook on Agriculture, 2011
The homogeneous topography of Argentina's flooding pampas conceals a substantial amount of spatial and temporal ecosystem heterogeneity. Differences in soils, grassland botanical composition and plant growth regimes that occur down to individual paddocks influence livestock grazing patterns and, predictably, affect the productivity of cattle ranches ...

Streamflow Elasticity to Precipitation Distribution and Potential Evapotranspiration Across South America

Hydrological Processes, Volume 40, Issue 2, February 2026.
Graphical abstract summarizing the modelling experiments used to quantify streamflow elasticity to changes and temporal redistribution of precipitation across South America, highlighting stronger effects of seasonal redistribution and larger responses in humid climates. ABSTRACT This study examines the sensitivity of mean, high and low streamflows (i.e.

Improvement of an induced autotetraploid population ofLotus tenuisfor their use in the Flooding Pampas [PDF]

WIT Transactions on Ecology and The Environment, 2013
In the Flooding Pampas, Argentina, as agricultural expansion spread into areas historically used for livestock grazing, it came to occupy the best soils in the area. The need therefore arose to increase the production of forage species able to adapt to increasingly stressed soil conditions.

Landscape Genomics and Evolutionary History of Megamelus scutellaris, a Biocontrol Agent of the Invasive Water Hyacinth (Pontederia crassipes)

Evolutionary Applications, Volume 19, Issue 2, February 2026.
ABSTRACT Understanding the evolutionary history of biological control agents in their native ranges is crucial for improving their selection, establishment, and performance across environmentally diverse regions. Phytophagous insects that specialize on aquatic plants offer particularly valuable models, as their evolutionary trajectories may be shaped ...

Exploring Phosphate Solubilizing Bacterial Communities in Rhizospheres of Native and Exotic Forage Grasses in Alkaline-Sodic Soils of the Flooding Pampa [PDF]

The flooding pampa is one of the most important cattle-raising regions in Argentina. In this region, natural pastures are dominated by low-productivity native grass species, which are the main feed for livestock.

A Novel Sampling Protocol for Fruit‐Feeding Butterflies in Grasslands and Open Habitats

Austral Ecology, Volume 51, Issue 1, January 2026.
This study proposed a novel sampling protocol for fruit‐feeding butterflies in grasslands and open areas in the subtropical region. The new method involves the use of Van Someren‐Rydon bait traps placed on specific supports closer to the ground, aiming to capture the true diversity of butterflies in these habitats.

Relative Abundance, Habitat Use, and Seasonal Variability of Raptor Assemblages In the Flooding Pampas of Argentina

Journal of Raptor Research, 2017
Abstract We evaluated the species composition, relative abundance, habitat use, and seasonal variability of raptor assemblages in the Flooding Pampas of Argentina, which represents the southeastern part of the biome known as the Rio de la Plata Grasslands.

Present and Future: Using Ecological Niche Modeling to Understand the Conservation Status of Alouatta caraya (Primates, Atelidae) and Promote Its Protection

American Journal of Primatology, Volume 87, Issue 8, August 2025.
Free‐living Alouatta caraya: the male (top left) and his females (bottom left). We used ecological niche modeling to assess the species' climate suitability both now and in future projections. Between now and 2030, there is a 31% reduction in distribution.

Effects of Continuous Grazing and Exclusion on the Structure of Modified Flooding Pampa Grassland in Argentina

, 2020
The breeding of beef cattle is the predominant activity in the Flooding Pampa wet grasslands. The stocking rate of this region is increasing because of livestock displaced by agriculture in other regions. This increased load has been achieved through the
