Germination behaviour of Italian ryegrass in flooding pampa rangelands
Seed Science Research, 1998AbstractLolium multiflorum Lam., a winter annual grass species originating from the Mediterranean region, has become widespread in native grasslands of the flooding pampa (Argentina). The dynamics of dormancy release of L. multiflorum seeds in simulated natural conditions was studied.

The effects of gypsum applied to a Natraquoll of the Flooding Pampas of Argentina
Soil Use and Management, 1998Abstract. The application of gypsum to a Natraquoll under pasture was evaluated in a humid area of the ‘Flooding Pampas’ of Argentina in a randomized block field design. Gypsum was incorporated at 0, 15, 35, and 60 t ha ‐1 .

Genesis, Properties and Management of Salt-Affected Soils in the Flooding Pampas, Argentina
2020The Flooding Pampa is a plain, covering around 90,000 km2 composed of eolian and alluvial deposits. It is characterized by its geomorphology, with low (0.1–0.01%) slopes and elevations, including the coastal flat. A significant fraction of the region has permanent or temporary lagoons, generally connected with the underground water.

Frequency of defoliation of native and naturalized species of the Flooding Pampas (Argentina)
Grass and Forage Science, 2001This study describes the effect of herbage mass of species on defoliation patterns in a multispecies temperate–subhumid natural grassland of the Flooding Pampas at low, medium and high sward herbage mass [761 ± 8·7, 989 ± 137 and 1591 ± 44·0 kg green dry matter (DM) ha–1 respectively] maintained by continuous grazing of cattle at variable stocking ...

Ecosystem services are only able to make a contribution to human well-being if they reach the users or beneficiaries. Therefore, it is important to differentiate the potential contributions of ecosystems (ecosystem service supply) from the fraction of the supply that is captured or used.

Habitat Use by Non-breeding Shorebirds in Flooding Pampas Grasslands of Argentina
Waterbirds, 2003Abstract We identified environmental variables and grassland characteristics that affect the use of natural grasslands by four migratory shorebird species (Patagonian: Rufous-chested Dotterel (Charadrius modestus) and Tawny-throated Dotterel (Oreopholus ruficollis); Nearctic: American Golden Plover (Pluvialis dominica) and Buff-breasted Sandpiper ...

Community Structure in Grazed and Ungrazed Grassland Sites in the Flooding Pampa, Argentina
American Midland Naturalist, 1989-We compared the community structure and composition of two contiguous grasslands, one that had been continuously grazed and one that had remained ungrazed since 1972. Basal cover was measured at both sites in 1976 and 1985. The structure of the grazed area was affected by grazing during these 9 years, which was indicated by the reduction of the cover ...

The halo-hydromorphic soils in the Inland Pampas, located in subhumid and semiarid environments of central Argentina, are governed by the depth and salinity of water table, salt content and sodium in the profile, and the excess of water. Its aptitude of use is ruled by the A horizon thickness, cemented horizons (hardpans or fragipans) and occurrence ...

Agriculture, Ecosystems & Environment, 2010
Temperate grasslands of Argentina are extensively grazed by domestic livestock. Primary production follows a seasonal pattern, with maximum vegetation growth in late spring and minimum in winter. During the last decade, winter forage productivity has been encouraged by promoting the growth of cool-season annual grasses through late summer applications ...

Applied Vegetation Science, 2005
Abstract Question: How do meteorological variations at seasonal, interannual scales differentially affect the canopy dynamics of four contrasting landscape units within a region? Location: Flooding Pampa, Buenos Aires, Argentina. 5000 km2. Central point: 35°15′ S, 57°45′ W. Methods: We used a 19-year series of the normalized difference vegetation index
