Post-Burn Recovery in the Flooding Pampa: Impact of an Invasive Legume [PDF]
Journal of Range Management, 1997 Winter burning of Paspalum quadrifarium Lam. stands ("pajonales") promotes colonization of denuded spaces by several alien species. Lotus tenuis Waldst et Kit. ("lotus"), a recent invader of the region, is able to reach very high densities between the resprouting bunches of the dominant species. Results of a removal experiment performed to evaluate the

Fragmentation Status of Tall-Tussock Grassland Relicts in the Flooding Pampa, Argentina [PDF]
Rangeland Ecology and Management, 2009 Abstract Since European settlement vast areas of the tall tussock grassland dominated by Paspalum quadrifarium Lam. and Paspalum exaltatum J. Presl (“pajonal” grassland) in the Flooding Pampa of Argentina were converted to croplands and short grasslands.

Postburning Legume Seeding in the Flooding Pampas, Argentina [PDF]
Journal of Range Management, 2000 In Argentina, Paspalum quadrifarium Lam. (paja colorada) forms tall dense grassland communities in the flooding pampas. Referred to locally as "pajonales", these grasslands generally have very low nutritional value for cattle, except at the post-burn regrowth stage. To improve forage quality and consumption by breeding cattle, Lotus tenuis Walst et Kit.

Flood Risk and Adaptation Strategies for Soybean Production Systems on the Flood-Prone Pampas under Climate Change [PDF]
Agronomy, 2021 In recent decades, multiple flood events have had a devastating impact on soybean production in Argentina. Recent advances suggest that the frequency and intensity of destructive flood events on the Argentinian Pampas will increase under pressure from climate change.

Long-lasting floods buffer the thermal regime of the Pampas [PDF]
Theoretical and Applied Climatology, 2016 The presence of large water masses influences the thermal regime of nearby land shaping the local climate of coastal areas by the ocean or large continental lakes. Large surface water bodies have an ephemeral nature in the vast sedimentary plains of the Pampas (Argentina) where non-flooded periods alternate with flooding cycles covering up to one third

Geophysical Monograph Series, Page 169-190., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Cross‐scale vegetation patterns of Flooding Pampa grasslands [PDF]
Journal of Ecology, 2001 Summary The spatial pattern of vegetation heterogeneity across different scales may indicate the major environmental controls on vegetation structure, and thus guide strategies for the conservation of biodiversity. We analysed cross‐scale vegetation patterns in a 90 000‐km2area of natural grasslands in the Flooding Pampa, Argentina.

Poplar Afforestation Effects on Grassland Structure and Composition in the Flooding Pampas [PDF]
Rangeland Ecology & Management, 2005 Tree establishment can have multiple effects on the production and biodiversity of rangelands. In mixed (C3–C4) grasslands, winter deciduous trees could favor cold-season species in the understory, improving forage availability in the most critical time of the year.

Effect of Phosphate Fertilization on Flooding Pampa Grasslands (Argentina) [PDF]
Rangeland Ecology & Management, 2007 Abstract We postulate that phosphorus (P) fertilization may increase above-ground net primary productivity ( ANPP ) of rotationally grazed rangelands without reducing the legume component, as does N fertilization. In doing so, we evaluated the effect of phosphate fertilization on the production and relative contribution of legumes and grasses of ...
