“…Based upon information from sites located in the adjacent Interserrana Plain, Politis, et al (2004), Martínez (2001), and Grill M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT et al (2007) postulated that initial population took place under arid to semi-arid climatic conditions. The human populations that would have lived in this area c. 11,000-10,000 BP would therefore done so under colder, dry sub-humid conditions (Quattrocchio et al, 2008;Tonni and Cione, 1994;Prieto, 1996;Tonni et al, 1999Tonni et al, , 2003. Between c. 10,500 and 9000 BP a change in these dry conditions towards higher rainfall levels and temperatures has been indicated by numerous proxy records from the Pampas region (Tonni and Fidalgo, 1978;Prado et al, 1987;Alberdi et al, 1989;Tonni y Cione, 1994;Prieto, 1996;Zárate et al, 1995Zárate et al, , 2000Zarate, 1997;Borrero et al, 1998;Bonadonna et al, 1999;Tonni et al, 1999;Martinez, 1999Martinez, , 2001Martinez, , 2007Prieto et al, 2004;Grill et al, 2007;Gutierrez y Martínez, 2008;Gutierrez et al, 2010).…”

The Tandilia range is a discontinuous series of hills and valleys located at the central area of the Pampean region (Argentina). The process of human settlement reached in this zone the highest population densities and reoccupation levels of Southern South America, developing under the strongly changing climatic conditions that characterized the Pleistocene-Holocene transition. This paper analyzes the geoarcheological and paleoenvironmental record of the Pleistocene-Holocene transition (c. 9400-10,500 14 C BP) recovered from cave and rockshelter sedimentary successions of the Tandilia range. The analysis of several lines of evidence (stratigraphic, geoarchaeological, archaeological, zooarchaeological, and paleobotanical), suggests that a cold arid to semi-arid climate characterized the late Pleistocene (c. 10,500 BP), and changed abruptly to warmer conditions towards the beginning of the Post-Glacial Period. As a consequence of this climatic amelioration, the populations inhabiting the Tandilia range would have been benefited by a higher availability of resources, which could explain the higher levels of site density and reoccupation found in the area during this period.

“…According to Tonni & Figalgo (1978), during Pleistocene the climatic conditions alternated between arid or semi-arid and humid. The predominance of dry and cold climate in the late Pleistocene is suggested by the presence of fossil pollen especially from the Brassicaceae (Quattrocchio et al, 2008), and of fossil of extant mammals from Patagonian and Central sub-regions, associated to arid or semi-arid and cold weathers (Microcavia australis and Pediolagus salinicola) (Tonni, 1981(Tonni, , 1985Tonni et al, 1992;Prado & Alberdi, 2010).…”

-Studies regarding Quaternary mammals from the Serra da Bodoquena (South-western Brazil, state of Mato Grosso do Sul) are scarce. In the region, the Fadas Cave has been an important paleontological site. Remnants of Pleistocene fauna were collected along a river channel inside the cave. It is the first record of Arctotherium, Scelidotheriinae and Nothrotheriinae in the Serra da Bodoquena. Smilodon populator, Eremotherium laurillardi, Gomphotheriidae and Glyptodontinae, already known for the region, were also identified. These new occurrences allow us to redefine the paleozoogeographical distribution of some of the aforementioned taxa. Herein we propose the expansion of the range of the Brazilian Intertropical Region, which should include Mato Grosso do Sul and São Paulo. The state of Rio Grande do Sul keeps a greater paleozoogeographical affinity to others temperate zones from Argentina and Uruguay. Taxa associated to open environments indicate the existence of large areas of savannas during the late Pleistocene in the Serra da Bodoquena.Key words: Brazilian Intertropical Region, Pampean Region, paleozoogeographical zones, Fadas Cave, Quaternary mammals, Serra da Bodoquena.RESUMO -Os estudos sobre mamíferos quaternários da Serra da Bodoquena (Mato Grosso do Sul) são escassos.

O Estado do Rio Grande do Sul mantém uma maior afinidade paleozoogeográfica com outras zonas temperadas da Argentina e do Uruguai.

“…The Belisario Creek is a tributary of the El Oro Creek, which flows into the Sauce Grande River. This is the main river in the southwest Pampa (Quattrocchio et al 2008), and the main water source of the Paso de Las Piedras dam that supplies water to the cities of Bahia Blanca (300 000 inhabitants) and Punta Alta (60 000 inhabitants) (Marucci et al 2011). The area is occupied by two major types of plant communities: short-needlegrass on poor soils and tall-tussock grasslands on rich soils (Loydi et al 2010).…”

Delgado M.I., Gaspari F.J., Kruse E.E. (2015): Land use changes and sediment yield on a hilly watershed in CentralEast Argentina. Soil & Water Res., Watershed management strategies need suitable techniques to be available in order to quantify sediment yield, among other relevant issues. The aim of this work was to estimate the sediment yield on a hilly watershed, for two different land use scenarios (years 1966 and 2011) and rainfall events (106 mm and 65.5 mm). The Modified Universal Soil Loss Equation was used to estimate the sediment yield produced by a single rainfall on the watershed of the Belisario Creek, placed south-west of the Buenos Aires province, Argentina. The information was processed using the Geographic Information System Idrisi Taiga ® . Modelling the 45-year distant land use scenarios allowed to estimate the high level of degradation that is currently taking place on the watershed. Also, we detected different responses through different areas of the watershed; the same rainfall event in the 2011 land use scenario compared to the 1966 scenario showed a 400% increment in sediment yield in the upper sub-watersheds, together with an almost 100% increment near the sink. Here we propose the urgent need to elaborate a sustainable plan for the watershed of the Belisario Creek, in order to establish action criteria that could help improve natural resources management. The methodology used could be also applied to neighbouring watersheds with similar characteristics in the region.
