Implicaciones Paleoambientales De La Presencia Del Género Ceratophrys (Anura, Ceratophryinae) en Contextos Arqueológicos De La Transición Pampeano-Patagónica en El Holoceno Tardío (Curso Inferior Del Río Colorado, Argentina)

Health and disease of hunter-gatherer groups from the eastern Pampa–Patagonia transition (Argentina) during the Late Holocene

“…The probabilistic distribution of radiocarbon dates suggests an increase in the archaeological signal during the last 1000 years, probably linked to a demographic growth (Martínez et al, 2013). Also, more stable settlements, inter-site variability, and changes in mobility were observed (Martínez, 2008(Martínez, -2009. Regarding funerary practices, multiple secondary burials and formal disposal areas were adopted during this period (Martínez et al, 2012).…”

“…This technology could provide other substances such as liq- uids and fermentable beverages that perhaps were not consumed regularly in the ILH (Flensborg, 2013). Furthermore, the increase in the frequency of grinding stones in the archaeological record, as well as more standardized and formal tool designs, suggests that plant resources played an important role in the hunter-gatherer diet during the FLH (Martínez, 2008(Martínez, -2009Armentano, 2012). From a comparative perspective, the frequencies shown in the study area are similar to those reported for neighboring regions (e.g.…”

“…According to the information generated at the regional level, it is suggested that physical activities played an important role in the development of osteoarthrosic lesions in the hunter-gatherer groups. In this sense, changes in social organization in the lower basin of the Colorado River during the FLH probably impacted on behaviors and activities of human groups (Martínez, 2008(Martínez, -2009. The adoption of a logistical mobility strategy, with more stable settlements and longer occupations, may have caused changes in the behavior of human groups.…”

“…Archaeological data for the Pampas and northeastern Patagonia regions (Argentina) indicate major changes and reorganization of cultural systems in hunter-gatherer groups during the Final Late Holocene (c. 14 C years BP). These changes included diverse socioeconomic and demographic phenomena such as population growth, population expansions, inter-ethnic contacts, social interaction networks at different spatial scales (local, regional, and extra-regional), territoriality, spatial circumscription, intensification and diversification of the subsistence activity, demographic packing, and possible regionalization (Barrientos and Pérez, 2004;Berón, 2007;Martínez, 2008Martínez, -2009Politis, 2008;Prates, 2008;Favier Dubois et al, 2009;Martínez et al, 2014).…”

Mammalia, Rodentia, Sigmodontinae, Holochilus brasiliensis (Desmarest, 1819): distribution extention

“…In fact, in Hilario Ascasubi (a locality about 15 km N Pedro Luro, see Figure 1) "big red rats" were observed by the Instituto Nacional de Tecnología Agropecuaria personal when they burned the vegetation covering of an irrigation channel; 2) In addition to taking advantage of irrigation channels H. brasiliensis recent discovery in southern latitudes could be linked to global warming (e.g., Moritz et al 2008) which would induce Brazilian species to move southwards (Udrizar Sauthier et al 2005); 3) This record represents a relictual population, remain of a wider past distribution, as H. brasiliensis was found in Late Holocene archaeological deposits (Figure 1) in the valleys of Negro River (Prates 2008), Limay River (Teta et al 2005), and Colorado River (Stoessel et al 2008).…”
